According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

In this article, we analyze the patterns of culture of honor within Spanish families. Each member of 271 Spanish four-member families completed a questionnaire containing scales for the culture of honor and for sociodemographic variables. The results show that intra-family similarities emerge. However, path analyses show that the gender and birth order of the child are relevant in predicting this similarity. In particular, the first-born child converges with their mother to a higher extent than the father regardless of their gender. (...) However, for the second-born child both parents instill their ideas about culture of honor in a gender congruent way. Furthermore, there are higher similarities within younger families, indicating a stronger influence from parents to children. Results are discussed in view of social role and gender social learning theories. (shrink)

We studied the relationship between perceived social image and life satisfaction in four different cultural groups. One-hundred nine Indian (63 females, 46 males), 67 Pakistani/Bangladeshi (36 females, 31 males), 76 White British (43 females, 33 males), and 94 European Americans (43 females, 48 males) completed measures on the cultural importance of social image, positive and negative emotions, academic achievement, and perceived social image. Indian and Pakistani/Bangladeshi participants valued social image more than White British and European-American participants. Consistent with this value (...) difference, a positive perceived social image predicted life satisfaction among Indian and Pakistani/Bangladeshi participants only. For these participants, perceived social image predicted life satisfaction above and beyond the effects of emotions and academic achievement. Academic achievement only predicted life satisfaction among White British and European Americans. Emotions were significant predictors of life satisfaction for all participants. (shrink)

ABSTRACTTwo studies examined anger and shame, and their associated appraisals and behavioral intentions, in response to harm to an in-group's social-image. In Study 1, 37 British Muslims reported incidents in which they were devalued as Muslims. In Study 2, 108 British Muslims were presented with objective evidence of their in-group's devaluation: the controversial cartoons about Prophet Muhammad The appraisal of harm to social-image predicted anger and shame, whereas the appraisal of offense only predicted anger. Anger was a more empowering response (...) than shame, as anger predicted willingness for public confrontation, institutional punishment, and written disapproval. In contrast, shame only predicted written disapproval. Furthermore, independent of individual differences in identification as Muslim, a mediation model showed that individual differences in honor orientation pre... (shrink)

Trolling—the online exploitation of website, chat, or game mechanics at another user's expense—can and does take place all over cyberspace. It can take myriad forms, as well—some verbal, like trash-talking an opponent in a game, and some silent, like refusing to include a new player in a team effort during an in-game quest. However, despite this variety, there are few to no studies comparing the effects of these differing trolling types on victims. In addition, no study has yet taken into (...) account users' offline cultural context and norms into the trolling victim experience. To fill this gap in the literature, the present study put participants from three culturally-distinct countries—Pakistan, Taiwan, and the Netherlands—in a simulated trolling interaction using the Cyberball game. Participants were either flamed or ostracized by a member of their own cultural group or a minority member, and the participants' emotional responses, behavioral intentions toward the other players, and messages sent during the game were taken as indicators of their response to the trolling. Results showed that our Taiwanese sample used the most reactive aggression when trolled and our Dutch sample was the most passive. In addition, ostracism generally produced the desire to repair relationships, irrespective of cultural context, and perpetrator culture only produced an effect in the behavioral intentions of our Pakistani sample. Overall, it would appear that online and offline culture interact to produce the variety of responses to trolling seen in extant literature. Additional implications for future research into computer-mediated communication and online aggression are also discussed. (shrink)
