The Impact of Intergroup Emotions on Forgiveness in Northern Ireland

Keywords: forgiveness, infrahumanization, intergroup contact, intergroup emotions

. Two studies showed that both the specifi c intergroup emotion of anger and infrahumanization (the attribution of more human emotions to the ingroup than to the outgroup) predicted decreased intergroup forgiveness in Northern Ireland. Results further revealed intergroup contact as a potential means of reducing anger toward the outgroup and improving attitudes toward them. This research integrated prior interpersonal theory with intergroup literature to examine the concept of intergroup forgiveness and its predictors. Results are discussed in terms of their implications for reconciliation in confl ict societies.

To escape a self-perpetuating cycle of violence and retaliation inherent in situations of widespread sectarian confl ict, violence on both sides must cease, and a strategy of cooperation must be pursued [START_REF] Mclernon | Views on forgiveness in Northern Ireland[END_REF]. Intergroup forgiveness may serve to break the cycle of violence and aid in the reconciliation process after a protracted intergroup confl ict. An understanding of intergroup forgiveness is of particular importance in post-confl ict societies such as Northern Ireland, where groups involved in intergroup confl ict are often encouraged to 'move on' from the past. Where intergroup confl ict is concerned, however, the past is intimately part of the present. The past forms part of the ongoing intergroup competition central to any intergroup confl ict, with people in Northern Ireland remembering battles fought long ago [START_REF] Cairns | The confl ict in Northern Ireland: Causes, consequences, and controls[END_REF].

The research on building forgiveness has centered on the individual and interpersonal levels (e.g. McCullough, Pargament, & Thoresten, 2000). Although the fi ndings of this research are relevant to the intergroup level, they are not immediately applicable to it. Therefore, relevant research on interpersonal forgiveness and the effects of forgiveness on individuals must be extrapolated and empirically examined on the intergroup level to elucidate why certain individuals on both sides of the divide are able to forgive past wrongs and break the cycles of revenge that typically escalate intergroup confl ict. On November 8, 1987, for instance, when Gordon Wilson's daughter, Marie, was killed in an IRA bomb attack, he said, 'I bear no ill will, I bear no grudge'. On the other side of the sectarian divide, Michael McGoldrick's son, Michael, was shot by Protestant paramilitaries on July 8, 1996, yet he pleaded, 'Bury your pride with my boy. To those who've done this, I and my family forgive you' [START_REF] Cairns | Intergroup forgiveness and intergroup confl ict: Northern Ireland, a case study[END_REF]. Such acts of forgiveness may break a cycle of vengeance and violence. Such acts are, however, rare.

Forgiveness permits the relationship between the confl icting parties to move forward after a transgression [START_REF] Zechmeister | Victim and offender accounts of interpersonal confl ict: Autobiographical narratives of forgiveness and unforgiveness[END_REF]. Forgiving a transgressor has, in fact, repeatedly been shown to result in less turmoil and more positive emotional reactions compared with not forgiving a transgressor [START_REF] Mccullough | Vengefulness: Relationships with forgiveness, rumination, well-being and the big fi ve[END_REF]. Thus, forgiveness may promote overall relationship satisfaction in interpersonal relations [START_REF] Kachadourian | Attitudinal ambivalence, rumination, and forgiveness of partner transgressions in marriage[END_REF]. On the intergroup level, forgiveness involves the release of negative feelings toward the perpetrator's group [START_REF] Tutu | No future without forgiveness[END_REF] and prosocial behaviors toward that group [START_REF] Wohl | Forgiveness and collective guilt assignment to historical perpetrator groups depend on level of social category inclusiveness[END_REF]. People who forgive a historical perpetrator category (e.g. Jews forgiving Germans) are, for example, more willing to become friends with a member of that group and to buy products made by them (e.g., German cars; [START_REF] Wohl | Forgiveness and collective guilt assignment to historical perpetrator groups depend on level of social category inclusiveness[END_REF].

Negative emotions that result from intergroup confl ict persist long after the violence itself has stopped [START_REF] Wohl | Forgiveness and collective guilt assignment to historical perpetrator groups depend on level of social category inclusiveness[END_REF]. These negative cross-community feelings must be addressed in the promotion of more positive intergroup relations and reconciliation of the two communities. This survey explores intergroup emotions in the prediction of intergroup forgiveness in Northern Ireland, based on theories of both interpersonal forgiveness and intergroup relations.

Intergroup emotions and forgiveness: the role of anger

Relations between groups often involve intense emotions, and although social psychological explanations for discriminatory behavior tend to focus on prejudice as an attitude, specifi c intergroup emotions may be more conducive to predicting intergroup behaviors than general outgroup evaluation is [START_REF] Smith | Social identity and social emotions: Toward new conceptualizations of prejudice[END_REF]. Differentiated emotions may be more accurate for predicting behavior than attitudes are, because evaluating groups as simply positive or negative does not allow for differential predictions about groups that are feared, hated, respected, or liked. Moreover, a greater variety of outgroup behaviors may be explained by various emotions (Mackie & Smith, 2002). Anger, for example, is particularly related to decreased forgiveness. In fact, according to [START_REF] Baumeister | The victim role, grudge theory, and two dimensions of forgiveness[END_REF], 'to forgive someone means to cease feeling angry or resentful over the transgression ' (p. 85). The process of forgiving, on the individual level, involves letting go of negative emotions without seeking to improve relations with the transgressor [START_REF] Baumeister | The victim role, grudge theory, and two dimensions of forgiveness[END_REF]. However, whether or not the victim seeks to improve relations with the transgressor, forgiveness can occur only after emotions aroused by offensive behavior have been addressed [START_REF] Harber | Emotional disclosure and closeness toward offenders[END_REF].

In forgiveness intervention programs, there is also a need to confront angry emotions after being hurt. For example, although Enright and colleagues' 'Process Model of Forgiveness' emphasizes cognitive processes such as reframing the offense, achieving insight, and fi nding meaning, it begins with the 'confrontation of anger' [START_REF] Enright | Researching the process model of forgiveness within psychological interventions[END_REF]. According to [START_REF] Freedman | Forgiveness as an intervention goal with incest survivors[END_REF], confronting hostile emotions comes before the cognitive shifts that solidify forgiveness: 'Before forgiving, one needs to express his or her justifi ed anger' (p. 985) and 'the point is to release, not harbor, the anger' (p. 986). The confrontation and expression of offense-related emotions is one of the most important elements in the 'Process Model of Forgiveness' [START_REF] Enright | Researching the process model of forgiveness within psychological interventions[END_REF].

Baumeister and colleagues (1998) explicitly defi ne forgiveness as an emotional state. Research indeed suggests that forgiveness is rooted in emotions (e.g. [START_REF] Harber | Emotional disclosure and closeness toward offenders[END_REF] and therefore should be constrained by the laws that govern emotions. One principle of emotions is that they are involuntary, in the sense that, once aroused, emotions cannot be defused at will [START_REF] Zajonc | Feeling and thinking: Preferences need no inferences[END_REF]. Thus, although a person may want to stop feeling angry, hostile, or resentful, directly trying to expunge these feelings may not be suffi cient to stop them. In fact, efforts to consciously suppress or deny these emotions are more likely to increase rather than decrease their infl uence [START_REF] Wegner | Mental control[END_REF]. Interventions are needed to deal with intergroup emotions themselves. Thus it is important to establish predictors of intergroup emotions. One such predictor is intergroup contact, which has been shown not only to promote positive intergroup emotions but also to mitigate negative ones [START_REF] Miller | Effects of intergroup contact and political predispositions on prejudice: Role of intergroup emotions[END_REF]. Specifi c emotions are states of immediate readiness to act [START_REF] Frijda | The emotions[END_REF] and are theorized as directing behavior [START_REF] Smith | Social identity and social emotions: Toward new conceptualizations of prejudice[END_REF]. [START_REF] Mackie | Intergroup emotions: Explaining offensive action tendencies in an intergroup context[END_REF] have shown that although anger and fear are both forms of negative affect, they are empirically distinct and provoke different intergroup behaviors: fear predicts avoidant action tendencies, while anger predicts aggressive action tendencies against the outgroup [START_REF] Devos | Experiencing intergroup emotions[END_REF]. In addition to these negative intergroup emotions, our recent studies have shown positive intergroup emotions to be key predictors of out-group attitudes and action tendencies [START_REF] Tam | The role of intergroup emotions and empathy in contact between Catholics and Protestants in Northern Ireland[END_REF]. In the case of predicting forgiveness toward the outgroup, the specifi c emotion of anger is likely to be involved. We thus tested this for the fi rst time on the intergroup level, and hypothesized that the specifi c intergroup emotion of anger would be a better predictor of decreased intergroup forgiveness than a general outgroup evaluation and other specifi c intergroup emotions would be. Wohl and Brancombe (2005) maintain that the resolution of social confl ict involves more than just changing negative beliefs; it is also necessary to see the humanity in the other. Their research demonstrated that perpetrator groups that are seen as 'human' elicit intergroup forgiveness and more positive intergroup behaviors toward the outgroup (i.e. increased willingness to befriend outgroup members and buy outgroup products). The Truth and Reconciliation Commission in South Africa has similarly shown us that what seems to be needed is an ability to see outgroup members as human like the self [START_REF] Tutu | No future without forgiveness[END_REF]. Such perceptions of the 'human family' may well be crucial for intergroup forgiveness and the creation of a more harmonious future (Wohl & Brancombe, 2005). We thus investigated the relationship between infra-humanization (seeing the outgroup as less human than the ingroup) and reduced intergroup forgiveness. Intergroup behavior may be a result not only of emotions felt toward the outgroup, but also of differential emotions attributed to the outgroup, i.e. fewer 'human' emotions attributed to the outgroup vs. the ingroup. Research has shown that people tend to infuse an essence (biological, cultural, religious, etc.) into social groups in order to explain their differences. Thus, an ingroup perceived as superior may be endowed with 'the' human essence, while outgroups are seen as 'infra-humans' [START_REF] Leyens | Psychological essentialism and the differential attribution of uniquely human emotions to ingroups and outgroups[END_REF]. Leyens and colleagues (2001) have demonstrated this 'infrahumanization' process in multiple groups with a history of mild confl ict (e.g. Flemish-speaking vs. French-speaking Belgians). They have shown that people perceive what emotion researchers (e.g. [START_REF] Ekman | Are there basic emotions?[END_REF] call secondary emotions (e.g. nostalgia) as more unique to humans than primary emotions (e.g. pleasure), which may also be attributed to animals. Researchers generally agree that emotions such as anger, fear, and joy are common to both animals and humans, while emotions such as guilt, melancholy, and embarrassment are unique to human beings [START_REF] Ekman | Are there basic emotions?[END_REF]. People tend to attribute secondary (human) emotions more to the ingroup than to the outgroup [START_REF] Leyens | The emotional side of prejudice: The attribution of secondary emotions to ingroups and outgroups[END_REF]. This infrahumanization has even been demonstrated on the implicit level [START_REF] Paladino | Differential association of uniquely and non uniquely human emotions with the ingroup & the outgroup[END_REF]. Using the Implicit Association Test [START_REF] Greenwald | Measuring individual differences in implicit cognition: The implicit association test[END_REF], Paladino and colleagues (2002) showed that participants implicitly associated secondary emotions with the ingroup and primary emotions with the outgroup more than the other way around.

Infrahumanization and forgiveness

In this study, we aimed to investigate Leyens and colleagues' concept of infrahumanization in an area with a history of extreme confl ict. We thus examined the differential attribution of secondary and primary emotions to the ingroup vs. the outgroup in Northern Ireland, and hypothesized that those who infra-humanized the outgroup less would be more willing to forgive them. As [START_REF] Tutu | No future without forgiveness[END_REF] and [START_REF] Wohl | Forgiveness and collective guilt assignment to historical perpetrator groups depend on level of social category inclusiveness[END_REF] suggest, forgiveness may be a particularly 'human' act.

Extensive evidence has established that positive interaction between members of different groups can reduce intergroup prejudice and hostility [START_REF] Allport | The nature of prejudice[END_REF][START_REF] Pettigrew | A meta-analytic test of intergroup contact theory[END_REF]. Intergroup contact has in fact long been considered one of psychology's most effective strategies for improving intergroup relations (Dovidio, Gaertner, & Kawakami, 2003). In this study, we examined potential differential outcomes that intergroup contact may have for intergroup relations in Northern Ireland. [START_REF] Paolini | Effects of direct and indirect cross-group friendships on judgments of Catholics and Protestants in Northern Ireland: The mediating role of an anxiety-reduction mechanism[END_REF] have shown that anxiety mediates the effects of contact on prejudice in Northern Ireland. Our previous research has revealed that it is not only anxiety but also other intergroup emotions (i.e. anger-related emotions and positive emotions) that explain the effects of contact on prejudice [START_REF] Tam | The role of intergroup emotions and empathy in contact between Catholics and Protestants in Northern Ireland[END_REF]. Emotional processes of healing are crucial to post-confl ict reconciliation [START_REF] Nadler | Post-resolution processes: Instrumental and socioemotional routes to reconciliation[END_REF], and anger is a particularly relevant emotion associated with forgiveness [START_REF] Mccullough | The psychology of forgiveness: History, conceptual issues, and overview[END_REF]. We therefore examined the impact of contact on specifi c intergroup emotions, such as anger, fear, and positive emotions, and hypothesized that people who experienced anger toward the outgroup would be particularly disinclined to forgive them, even after controlling for people's general evaluation of the outgroup. We hypothesize moreover that specifi c intergroup emotions such as anger will be more predictive of outcome variables such as intergroup forgiveness than will a general evaluation such as general attitude toward the outgroup.

The current research

The current research investigates the predictors of intergroup forgiveness in Northern Ireland. It is crucial to investigate forgiveness and reconciliation in real confl ict situations, as laboratory research cannot take into account contextual variables vital to intergroup relations in confl ict areas [START_REF] Pettigrew | Generalized intergroup contact effects on prejudice[END_REF]. Since 1969, over 3,600 people have been killed in sectarian violence in Northern Ireland, and more than half the Northern Irish population knows someone who was injured or killed in 'The Troubles' [START_REF] Smyth | The human costs of the troubles[END_REF]. Many people in Northern Ireland, especially the Protestant community, believe it should remain part of the United Kingdom. Others, particularly the Catholic community, take the opposite perspective and believe it should instead become part of the Republic of Ireland. Religious polarization in Northern Ireland is so strong that vital aspects of life (e.g. areas of residence, schools, shops, political parties, sports, fi rst and last names) can be identifi ed as being either Catholic or Protestant (see Hargie & Dickinson, 2003).

Despite resolution of a range of economic and social issues (such as differential employment, education, and housing for Catholics and Protestants), division is still highly symbolic and psychologically real, and the confl ict pervades people's everyday lives. In a post-confl ict society, it is imperative to promote intergroup harmony, but the question remains, how can this best be done? In this study, we address the mechanisms underlying intergroup forgiveness in Northern Ireland.

Intergroup forgiveness in the context of Northern Ireland

To elucidate the concept of intergroup forgiveness in Northern Ireland, McLernon, Cairns, Hewstone, and Smith (2002) conducted a series of focus groups with people from organizations devoted to the reduction of conflicts, exparamilitary group members, and victims themselves. Most participants agreed that it was easier to forgive an individual than a group, because it was easier to trust an individual than each member of the other community. Victims were hostile to the idea of forgiveness and viewed forgiveness as an act that justifi ed the wrongs done to them. Ex-members of paramilitary groups were similarly hostile; they felt their acts were justifi ed at the time and that they did not need to ask for, or offer, forgiveness. All groups stressed that attempting to impose intergroup forgiveness was likely to be counterproductive, but that an act of remembrance such as a monument might give people the opportunity to share the loss and make forgiving easier.

We used a measure of intergroup forgiveness in Northern Ireland that was developed from these focus groups (see [START_REF] Mclernon | Views on forgiveness in Northern Ireland[END_REF] to investigate the concept of intergroup forgiveness and assess psychological processes that may foster or inhibit forgiveness in Northern Ireland. We explored the predictors of intergroup forgiveness in Northern Ireland, basing our conceptualization of intergroup forgiveness on the results of focus groups as well as on previous research and theorizing on interpersonal forgiveness, intergroup relations, and emotion, and the small literature on intergroup forgiveness in this context [START_REF] Hewstone | Intergroup forgiveness and guilt in Northern Ireland: Social psychological dimensions of 'The Troubles[END_REF][START_REF] Hewstone | Intergroup contact, forgiveness, and experience of 'The Troubles' in Northern Ireland[END_REF], which suggests segregation in Northern Ireland to hinder intergroup forgiveness.

On this basis, we hypothesized that: (1) angerrelated intergroup emotions would be particularly associated with decreased intergroup forgiveness; and (2) infra-humanization would also be associated with decreased intergroup forgiveness. We hypothesized a model in which intergroup contact would be associated with decreased anger and infra-humanization, which would in turn lead to increased intergroup forgiveness. This model is depicted in Figure 1. Anger, infrahumanization, and attitudes were examined at the same level, as no causal order among them was hypothesized. The plus signs indicated a hypothesized positive relation between variables, and the minus signs indicated a hypothesized negative relation between variables.

Study 1

Method

Participants and procedure Participants were 97 students from three universities in Northern Ireland. Thirty-six participants identifi ed themselves as Protestant; sixty-one identifi ed themselves as Catholic. Seventy-fi ve participants were female, 18 were male, and 4 did not report their sex; their mean age was 23 years (SD = 6.3). Participants were asked to complete a questionnaire about social attitudes and intergroup relations.

Measures

Intergroup forgiveness The measure of intergroup forgiveness was a shortened form of one used in previous research [START_REF] Hewstone | Intergroup forgiveness and guilt in Northern Ireland: Social psychological dimensions of 'The Troubles[END_REF][START_REF] Hewstone | Intergroup contact, forgiveness, and experience of 'The Troubles' in Northern Ireland[END_REF], developed through a series of focus groups with Northern Irish citizens (see [START_REF] Mclernon | Views on forgiveness in Northern Ireland[END_REF]. Participants were given the instructions: 'You may have read in the newspapers, or heard/seen discussions on the radio and TV about reconciliation and forgiveness in Northern Ireland. Now, please tell us how you feel about these issues'. Participants rated four items on 4-point scales (1 = Disagree strongly, 4 = Agree strongly): 'Only when the two communities of Northern Ireland learn to forgive each other can we be free of political violence', 'My community should, as a group, seek forgiveness from the other community for past paramilitary activities', 'Northern Ireland will never move from the past to the future, until the two communities learn to forget about the past', and 'Northern Ireland will never move from the past to the future, until the two communities learn to draw a line under the past'. Cronbach's alpha for these four items was .69. Mackie et al.'s (2000) scale was adapted to assess negative (angry and fearful) intergroup emotions in Northern Ireland, and a set of positive emotions was added to this scale. Participants were asked to rate how much of each emotion (angry, hatred, furious, irritated, nervous, anxious, fearful, worried, afraid, cheerful, happy, pleasant) they felt when thinking about members of the other community on 7-point scales (0 = Not at all, 6 = Extremely). These emotions were presented in a randomized order.

Intergroup emotions

To examine the structure of emotional reactions to the outgroup, we conducted factor analyses. First, a principal components analysis on the 12 emotion items, retaining eigenvalues greater than 1, revealed three factors that accounted for 76.8% of the variance. Factor loadings, after varimax rotation, showed that all the anger items (angry, hatred, furious, irritated) loaded onto the fi rst factor (> .69), all the fear items (nervous, anxious, fearful, worried, afraid) loaded onto the second factor (> .80), and all the positive emotion items (cheerful, happy, pleasant) loaded onto the third factor (>. 81), suggesting that anger, fear, and positive emotions were clearly distinct intergroup emotions. Cronbach's alpha for the four anger-related items was .89. For the fi ve fear-related items, it was .93, and for the three happy-related items, it was .82. (2001) was adapted for the Northern Irish context and assessed the differential attribution of primary (universal) and secondary (uniquely human) emotions to the outgroup vs. the ingroup with two checklists. Participants were asked to mark the words which they believed to be typical of the other community (outgroup) in one list and to mark the words which they believed to be typical of their own community (ingroup) in the other list. The lists consisted of seven positive primary emotions (surprise, calmness, attraction, enjoyment, caring, excitement, pleasure), seven positive secondary emotions (optimism, love, passion, elation, nostalgia, admiration, hope), seven negative primary emotions (pain, fear, anger, fury, panic, fright, suffering), and seven negative secondary emotions (humiliation, shame, guilt, disgust, melancholy, disconsolate, disenchantment). As in previous research, participants were asked to select as many traits as they liked but were encouraged to choose traits sparingly and to limit their choices to descriptors they believed to be especially relevant to their or the other community.

Infrahumanization The measure of infrahumanization developed by Leyens and colleagues

Outgroup attitudes Attitudes toward the other community were assessed using a modifi ed version of Wright, Aron, McLaughlin-Volpe, & Ropp's (1997) 'General Evaluation Scale'. Participants were asked to evaluate the other community on 5-point semantic differential scales (1-5): warm-cold (reverse-coded), negative-positive, friendly-hostile (reverse-coded), generousselfi sh (reverse-coded), insensitive-sensitive, and insincere-sincere. The six items created a reliable index refl ecting attitudes toward the other community. Cronbach's alpha for these six items was .82.

Intergroup contact Contact quantity was assessed by asking participants, 'How much contact do you have with people who are of a different religion to you/from the other community in just chatting to people?' on a 7-point scale (0 = None at all, 6 = A great deal). Contact quality was assessed by asking participants, 'In general, when you meet people of a different religion/from the other community, do you fi nd the contact pleasant or unpleasant?' on a 7-point scale (0 = Very unpleasant, 6 = Very pleasant). To measure the amount of high quality contact, the interaction between quantity and quality of contact was examined, by multiplying quantity and quality of contact together. This procedure, adopted by previous researchers (e.g. [START_REF] Voci | Intergroup contact and prejudice toward immigrants in Italy: The mediational role of anxiety and the moderational role of group salience[END_REF], allows us to consider these two aspects of contact simultaneously. In fact, quantity or quality of contact taken separately are often not enough to reduce prejudice; an optimal combination of the two is needed [START_REF] Allport | The nature of prejudice[END_REF].

Results and discussion

We hypothesized that anger and infrahumanization would be associated with decreased intergroup forgiveness. To assess infrahumanization, we computed composite scores for the number of primary and secondary emotions attributed to the ingroup and outgroup for each participant by combining the selected emotions. To control for the number of emotions selected in general, proportion scores were calculated such that each composite score was divided by the total number of emotions selected. We then calculated a fi nal infrahumanization score by subtracting the proportion score for secondary emotions attributed to the ingroup from the proportion score for secondary emotions attributed to the outgroup. The difference between the proportion score of primary emotions attributed to the outgroup and the proportion score of primary emotions attributed to the ingroup was also computed. We similarly examined the differential valence of emotions attributed to the ingroup vs. the outgroup, and calculated the proportion of positive and negative emotions attributed to ingroup vs. the outgroup.

To investigate the hypothesized predictors of intergroup forgiveness, regression analyses were conducted, and forgiveness was regressed onto quality of contact, quantity of contact, and their cross-product, anger, fear, and positive intergroup emotions, outgroup attitude, infra-humanization, the differential attribution of primary emotions to the ingroup vs. the outgroup, and the differential attribution of positive and negative emotions to the ingroup vs. the outgroup (to account for valence) simultaneously. As predicted, anger and intra-humanization predicted reduced forgiveness (β = -.40, p < .01 and β = -.26, p < .05, respectively), over and above the effects of quality of contact (β = -.15, ns), quantity of contact (β = -.16, ns), quality × quantity (β = .18, ns), fear (β = .23, p < .05), positive emotions (β = .03, ns), outgroup attitude (β = .20, p < .05), the differential attribution of primary emotions to the ingroup vs. the outgroup (β = .07, ns), and the differential attribution of positive and negative emotions to the ingroup vs. the outgroup (β = .08 and β = -.17, respectively, both ns).

We then evaluated the proposed model with only the hypothesized (manifest) variables (see Figure 1) using structural equation modeling (AMOS 5.0; Arbuckle, 2004). Covariance matrices were used as input (see Table 1), and estimates were derived using the maximum likelihood procedure. To assess overall model fi t, we used the chi-square test, the comparative fit index (CFI), the root mean square of approximation (RMSEA), and the standardized root mean square residual (SRMR). A satisfactory fi t is generally indicated by a χ 2 /df ratio ≤ 3, a CFI ≥ .95, an RMSEA ≤ .08, and an SRMR ≤ .08 [START_REF] Voci | Intergroup contact and prejudice toward immigrants in Italy: The mediational role of anxiety and the moderational role of group salience[END_REF].

The structural equation model examined intergroup contact as a potential predictor of anger-related emotions, infrahumanization, and outgroup attitudes, which in turn predicted intergroup forgiveness. Intergroup contact was assessed as the cross-product of quantity and quality of contact, as in previous research (e.g. [START_REF] Voci | Intergroup contact and prejudice toward immigrants in Italy: The mediational role of anxiety and the moderational role of group salience[END_REF].The fi t of the model was good (χ 2 = .02, df = 1, p = .88, χ 2 / df = .024, CFI = 1.00, RMSEA = .00, SRMR = .00). As expected, the model showed that anger, infrahumanization, and outgroup attitudes were signifi cant predictors of intergroup forgiveness in the model (β = -.27, β = -.21, and β = .21, all p < .05). Moreover, intergroup contact predicted reduced anger and more positive outgroup attitudes, and marginally predicted reduced infrahumanization. Twenty-three per cent of the variance in forgiveness was explained in the model (see Figure 2). Alternative models Although the hypothesized model fi ts the data well, there are always alternatives (MacCullem & Austin, 2000), especially for a relatively new area of investigation such as that of intergroup forgiveness. We thus considered two options. In the fi rst alternative model, we tested the potential for forgiveness to mediate the effects of the originally hypothesized mediators on promoting intergroup contact. The model thus included decreased anger, decreased infrahumanization, and more positive attitudes as predictors of greater intergroup forgiveness, which then predicted higher levels of positive contact. The second alternative model tested the possibility that forgiveness mediates the effects of contact on the originally hypothesized mediators. In other words, contact leads to greater intergroup forgiving, which then leads to decreased anger, decreased infrahumanization, and more positive attitudes. The two alternative models are statistically equivalent, as they are the reverse causal models of one another. These alternative models did not fi t the data better than the proposed model did (χ 2 (3) = 10.14, p = .02; RMSEA = .15; SRMR = .08; CFI = .87).

In fact, they fi t the data signifi cantly worse than the proposed model did (∆χ 2 = 10.12, ∆df = 2, p < .05. Lastly, we hypothesized that the relationship between the specifi c intergroup emotion of anger and intergroup forgiveness would be stronger than the relationship between general evaluation (outgroup attitude) and forgiveness. Although the effect of anger on forgiveness was more highly signifi cant than the effect of outgroup attitudes on forgiveness, we conducted a structural equation model with equality constraints imposed to statistically compare their effects and confi rm that this difference was signifi cant. Equality constraints were placed on the paths from anger to forgiveness and from attitudes to forgiveness. The fi t of this model was signifi cantly worse than the fi t of the original model in which coeffi cients were freely estimated (unconstrained) (χ 2 (2) = 15.70, p < .001; RMSEA = .25; SRMR = .10; CFI = .76). The difference in χ 2 was 15.68, ∆df = 1, p < .05, indicating that anger predicted signifi cantly more variance in intergroup forgiveness than did attitudes.

The results of Study 1 confi rmed the hypotheses. As predicted, both anger and infrahumanization predicted reduced forgiveness, over and above the effects of the other variables. That is, controlling for the effects of other intergroup emotions, contact, outgroup attitudes, and the differential attribution of primary, positive, and negative emotions to the ingroup vs. the outgroup shows the importance of anger and the differential attribution of secondary, rather than primary or valenced emotions, for predicting decreased forgiveness. Moreover, our hypothesized model of the predictors of intergroup forgiveness was confi rmed. However, because of the small size of our sample, we sought to replicate the fi ndings in a second study. It might also be argued, given the exact wording of the four items used in this study, that our measure of intergroup forgiveness, in fact, refl ected respondents' attitudes toward forgiveness, rather than their actual forgiveness toward the outgroup. We therefore sought to improve this measure in our second study. We included all 10 items from the original 'Intergroup Forgiveness Scale for Northern Ireland' [START_REF] Hewstone | Intergroup forgiveness and guilt in Northern Ireland: Social psychological dimensions of 'The Troubles[END_REF][START_REF] Hewstone | Intergroup contact, forgiveness, and experience of 'The Troubles' in Northern Ireland[END_REF] and we added nine new items tailored to refl ect defi nitions of forgiveness from the literature, i.e. in terms of a decreasing motivation to enact retribution and revenge [START_REF] Mccullough | Interpersonal forgiving in close relationships[END_REF], letting go of negative affect in response to considerable injustice [START_REF] Rye | Forgiveness and romantic relationships in college: Can it heal the wounded heart[END_REF], and abandoning the right to resentment and retaliation, and instead offering mercy to the offending party [START_REF] Enright | Researching the process model of forgiveness within psychological interventions[END_REF].

Study 2

Method

Participants and procedure Participants were 101 students from a large university in Northern Ireland. Thirty-eight participants identifi ed themselves as Protestant; 60 identifi ed themselves as Catholic, and three identifi ed themselves as other. These three were removed from further analyses. Forty-eight participants were female, 44 were male, and 6 did not report their sex; their mean age was 22 years (SD = 3.8). As in Study 1, participants were asked to complete a questionnaire about social attitudes and intergroup relations.

Measures

Intergroup forgiveness

The new measure of intergroup forgiveness comprised 19 items, the four used in Study 1 and the following (each of which participants were asked to rate on 4-point scales, 1 = Disagree strongly, 4 = Agree strongly): 'It is important that my community never forgets the wrongs done to us by the other community' (reverse-coded); 'It is important that my community never forgives the wrongs done to us by the other community' (reversecoded); 'My community has remained strong precisely because it has never forgiven past wrongs committed by the other community' (reverse-coded); 'I forgive the other community for past paramilitary activities'; 'I will never forgive past wrongs committed by the other community' (reverse-coded); 'It is important that we release our negative feelings toward the other community'; 'It is important that we abandon our right to resentment and retaliation'; 'I believe we should be merciful toward offenders from the other community'; 'I am able to view offenders from the other community with compassion'; 'I am able to let go of the negative emotions I have felt toward members of the other community who have acted unjustly to my community'; 'I believe revenge should be sought for acts committed by members of the other community' (reversecoded); 'We should forgive members of the other community for their past misdeeds'; 'We should never forgive members of the other community for past wrongs' (reverse-coded); 'The two communities in Northern Ireland must learn not to retaliate against political violence'; and 'People in my community think it is important to take revenge for all atrocities committed by the other community' (reverse-coded). Cronbach's alpha for the full scale was .89.

Intergroup emotions Intergroup emotions were assessed with the same scale as in Study 1. The principal components analysis on the 12 items, retaining eigenvalues greater than 1, again revealed three factors that accounted for 78.1% of the variance. Factor loadings, after varimax rotation, as in Study 1, showed that all the anger items (angry, hatred, furious, irritated) loaded onto the fi rst factor (> .72), all the fear items (nervous, anxious, fearful, worried, afraid) loaded onto the second factor (> .67), and all the positive emotion items (cheerful, happy, pleasant) loaded onto the third factor (> .78). Cronbach's alpha for the four anger-related items was .92; for the fi ve fear-related items, it was .91; and for the three happy-related items, it was .86.

Infrahumanization The measure of infrahumanization was the same as in Study 1.

Outgroup attitudes Attitudes toward the other community were assessed using a slightly different version of [START_REF] Wright | The extended contact effect: Knowledge of cross-group friendships and prejudice[END_REF] 'General Evaluation Scale'. Participants were asked to evaluate the other community on 5-point semantic differential scales (1-5): warm-cold (reverse-coded), negative-positive, friendly-hostile (reverse-coded), suspicioustrusting, respect-contempt (reverse-coded), and admiration-disgust (reverse-coded). The six items created a reliable index refl ecting attitude towards the other community. Cronbach's alpha for these six items was .86.

Intergroup contact Intergroup contact was assessed in the same way as in Study 1. Again, to measure the amount of high quality contact, the quantity and quality of contact were multiplied together (see [START_REF] Voci | Intergroup contact and prejudice toward immigrants in Italy: The mediational role of anxiety and the moderational role of group salience[END_REF].

Results and discussion

As in Study 1, to investigate the hypothesized predictors of intergroup forgiveness, regression analyses were conducted, and forgiveness was regressed onto quality of contact, quantity of contact, and their cross-product, anger, fear, and positive intergroup emotions, outgroup attitude, infrahumanization, the differential attribution of primary emotions to the ingroup vs. the outgroup, and the differential attribution of positive and negative emotions to the ingroup vs. the outgroup. As predicted, anger and infrahumanization predicted reduced forgiveness (β = -.59, p < .001 and β = -.25, p < .01, respectively), over and above the effects of quality of contact (β = .38, ns), quantity of contact (β = .04, ns), quality × quantity (β = -.39, ns), fear (β = .23, p < .06), positive emotions (β = .07, ns), outgroup attitude (β = .11, ns), the differential attribution of primary emotions to the ingroup vs. the outgroup (β = .18, ns), and the differential attribution of positive and negative emotions to the ingroup vs. the outgroup (β = .00 and β = -.26, respectively, both ns) (see Table 2).

We then evaluated the proposed model with only the relevant (manifest) variables (see Figure 1) using structural equation modeling (AMOS 5.0; Arbuckle, 2004). The structural equation model examined intergroup contact, as the cross-product of quantity and quality of contact, as a potential predictor of anger-related emotions, infrahumanization, and outgroup attitudes, which in turn predicted intergroup forgiveness. The fi t of the model was good (χ 2 = .01, df = 1, p = .91, χ 2 /df = .01, CFI = 1.00, RMSEA = .00, SRMR = .00). As expected, the model showed that anger, infrahumanization, and outgroup attitude were signifi cant predictors of intergroup forgiveness in the model (β = -.53, β = -.19, and β = .19, all p < .05). Intergroup contact predicted reduced anger toward the outgroup (β = -.49, p < .001) and more positive outgroup attitudes (β = .53, p < .001); however, contact did not predict reduced infrahumanization (β = .10, ns). Fortyfour per cent of the variance in forgiveness was explained by our model (see Figure 3).

Alternative models

We again considered two alternatives to the model proposed. The fi rst alternative model again included decreased anger, decreased infrahumanization, and more positive attitudes as predictors of greater intergroup forgiveness, which then predicted higher levels of positive contact. The second alternative model tested the possibility that contact leads to greater intergroup forgiving, which then leads to decreased anger, decreased infrahumanization, and more positive attitudes. The alternative models did not fi t the data better than the proposed model did (χ2 (3) = 27.22, p < .001; RMSEA = .29; SRMR = .08; CFI = .79). As in Study 1, these two alternative models are statistically equivalent, as they are the reverse causal models of one another, and again both alternative models fi t the data signifi cantly worse than the proposed model did (∆χ2 = 27.21, ∆df = 2, p < .05.

Finally, we again hypothesized that the relationship between the specifi c intergroup emotion of anger and intergroup forgiveness would be stronger than the relationship between a general evaluation (outgroup attitude) and forgiveness. Although the effect of anger on forgiveness was more highly signifi cant in the model than the effect of outgroup attitudes on forgiveness, we conducted a structural equation model with equality constraints imposed to compare their effects statistically and confi rm that this difference was signifi cant. Equality constraints were placed on the paths from anger to forgiveness and from attitudes to forgiveness. The fi t of this model was signifi cantly worse than the fi t of the original model in which coeffi cients were freely estimated (unconstrained) (χ2 (2) = 45.52, p < .001; RMSEA = .46; SRMR = .19; CFI = .65). The difference in χ 2 was 45.51, ∆df = 1, p < .05, indicating that anger predicted signifi cantly more variance in intergroup forgiveness than did attitudes.

General discussion

Both Catholics and Protestants have experienced a history of murder and violence from the other community [START_REF] Smyth | The human costs of the troubles[END_REF]. Although the Belfast Agreement (signed on April 10, 1998) provided a way forward from 'The Troubles' (setting up a local assembly and a power-sharing government, embracing all the major political parties), the formal resolution of a confl ict is often only the fi rst step toward peaceful coexistence. Individuals within and beyond the parties involved must then engage in psychological processes to overcome their blighted history and engage in reconciliation (see Hewstone et al., in press). Forgiveness plays a key role in helping groups in confl ict put the atrocities of the past behind them [START_REF] Cairns | Intergroup forgiveness and intergroup confl ict: Northern Ireland, a case study[END_REF]. To explore forgiveness at the community level rather than at the individual level, we used a measure of intergroup forgiveness that examined factors beyond personalized trauma on the individual level. This measure was designed from focus groups which specifi cally aimed to understand the concept of intergroup forgiveness in the context of Northern Ireland [START_REF] Mclernon | Views on forgiveness in Northern Ireland[END_REF]. Based on the results of the focus groups as well as on previous theory and research on forgiveness and intergroup relations, key predictors of intergroup forgiveness were hypothesized and tested. Anger and infrahumanization were identifi ed as proximal predictors of intergroup forgiveness, even after the effects of outgroup attitude, other emotions, and other variables were controlled for.

In this article, we provided two empirical examinations of the predictors of forgiveness in a real post-confl ict area. These two studies not only elucidated mechanisms which hinder forgiveness toward the outgroup-namely anger toward and infrahumanization of the other community-but they also demonstrated the potential for frequent positive intergroup contact to mitigate that anger toward the outgroup and improve outgroup attitudes, and thereby increase the likelihood of forgiveness. Study 1 showed that intergroup contact was marginally predictive of reduced infrahumanization; however, Study 2 did not confi rm this fi nding. Thus, although results showed that infrahumanization is detrimental to the process of forgiving the outgroup for past wrongs, contact may not necessarily ameliorate this infrahumanization.

Although fear and anger were signifi cantly correlated, both being negative affect, they were distinctly separate emotions which differentially predicted forgiveness. While anger predicted reduced forgiveness, interestingly fear predicted increased outgroup forgiveness in both studies, although this effect was only marginal in Study 2 (p < .06). (We believe, from focus groups and other research we have conducted, that fear relates to 'The Troubles' erupting again, and the understanding that mutual forgiveness must be a key part of the process of reconciliation needed to avoid that.) Positive emotions toward the outgroup did not relate to forgiveness. That is, it is not necessary for people to feel good about the other community to forgive them. But people who feel angry will not forgive. These results are consistent with previous research on interpersonal forgiveness, which demonstrates a strong link between feelings of anger toward a transgressor and lack of forgiveness. Anger impedes forgiveness [START_REF] Worthington | The pyramid model of forgiveness: Some interdisciplinary speculations about unforgiveness and the promotion of forgiveness[END_REF]. To achieve intergroup forgiveness, it is also vital for group members to see the humanity in the other. Results supported this hypothesis and demonstrated the inverse relationship between infrahumanization and forgiveness. That is, people who infrahumanized the outgroup (and saw them as less human) tended to be less forgiving of the outgroup for past wrongs committed. Intergroup forgiving may thus be a result not only of reduced anger felt toward the outgroup, but also of an increased perception of the outgroup's humanity. Confi rming our hypothesis, the differential attribution of secondary emotions to the ingroup over the outgroup (infrahumanization) was negatively related to intergroup forgiveness, over and above the differential attribution of primary (and positive and negative) emotions to the ingroup vs. the outgroup. The results thus demonstrated predictive validity for the infrahumanization measure in Northern Ireland and were in line with the hypothesis and previous research in other parts of the world. [START_REF] Smith | Social identity and social emotions: Toward new conceptualizations of prejudice[END_REF] intergroup emotions theory shifted the fi eld of intergroup relations away from the traditional notion of prejudice as outgroup attitude to the conceptualization of prejudice as emotion. We explored this distinction empirically and predicted that the relationship between specifi c intergroup emotions and intergroup forgiveness would be stronger than the relationship between general evaluation (outgroup attitude) and forgiveness. Results showed that anger-related intergroup emotions predicted forgiveness. The signifi cantly worse fi t of the model with equality constraints imposed confi rmed that anger predicted more variance in intergroup forgiveness than did outgroup attitudes. The results thus favored the ability of emotion (specifi cally anger) to predict intergroup forgiveness over that of outgroup attitude, and demonstrated the inverse relationship between the specifi c emotion of anger and intergroup forgiveness. Thus, it may not be enough to like the outgroup in order to forgive them. Factors beyond simply having positive outgroup attitudes need to be addressed in order to achieve forgiveness.

Intergroup forgiveness plays an integral part in the achievements of organizations such as the Northern Ireland Victims Commission. However, despite the importance of intergroup forgiveness for areas of confl ict, empirical research on this construct is lacking. Results suggest that the promotion of intergroup forgiveness in confl ict societies should involve certain psychological processes. The reduction of the specifi c intergroup emotion of anger should be targeted in particular; in addition, interventions should aim to decrease infra-humanization of the outgroup. The data, moreover, suggest contact to be one intervention that may help to decrease anger toward the outgroup for perceived past offenses and enhance more positive attitudes toward them.

Of course, these implications must be considered alongside the cross-sectional nature of our research, which makes it diffi cult to establish causality defi nitively in our model. However, previous research and theory suggest the causal order we proposed, and the ability of SEM to test complex a priori predictions and alternative models allows for some optimism about its assumed causal directions. Moreover, this research was also conducted in the context of real intergroup confl ict, rather than with manipulated variables in a laboratory, as we aimed to investigate people's real-life experiences of intergroup emotions and contact in context. To fi nd signifi cant effects under these circumstances suggests that we are dealing with robust and important empirical relationships. However, we acknowledge that the reverse causal model may also, perhaps even simultaneously, hold true; intergroup forgiveness may also lead to decreased anger, decreased infra-humanization, and more positive outgroup attitudes, which, in turn, lead to increased intergroup contact. (This model is however statistically equivalent to the proposed model, and thus cannot be tested in comparison.)

The results of this study established predictors of forgiveness for the outgroup. By understanding the antecedents of intergroup forgiveness, it may be possible to create theoretically driven interventions to increase forgiveness in an area of confl ict. Focus groups with Northern Irish citizens have shown a strong antipathy to imposing forgiveness upon victims of intergroup violence. To promote intergroup forgiveness, therefore, it is perhaps more important to look at the established predictors of intergroup forgiveness. Interventions should aim to include elements of targeting the specifi c emotion of anger as well as emphasizing the 'humanity' of members of the outgroup. John Hume, who shared the Nobel Peace Prize for his role in furthering the peace process in Northern Ireland, emphasized the vital role 'humanizing the other' has played. 'We have to realise', he said, 'that our common humanity transcends our differences'. As part of the healing process, Hume advocated programs that encourage Catholics and Protestants to live, work, and be educated together. 'The real border is not between north and south', he said, 'but in the minds and hearts of our people' (Dozier, 2002, p. 291).

For post-confl ict societies such as Northern Ireland, an understanding of the psychological factors that promote intergroup forgiveness is imperative, and the consequences of a history of intergroup violence must be addressed. Opportunities for people to deal with their grievances and anger-which clearly hold the potential to derail the peace process-must be provided. Deep engagement can help people see the humanity of the other by addressing prior hurts, pain, and violence that the groups have infl icted upon each other [START_REF] Staub | Individual and group identities in genocide and mass killing[END_REF]. A more complete understanding of intergroup forgiveness will leave us better prepared to take on the challenges involved in the process of reconciliation in post-confl ict societies.
