Altruism in social networks: Evidence for a ‘kinship premium’

Why and under what conditions are individuals altruistic to family and friends in their social networks? Evolutionary psychology suggests that such behaviour is primarily the product of adaptations for kin‐ and reciprocal altruism, dependent on the degree of genetic relatedness and exchange of benefits, respectively. For this reason, individuals are expected to be more altruistic to family members than to friends: whereas family members can be the recipients of kin and reciprocal altruism, friends can be the recipients of reciprocal altruism only. However, there is a question about how the effect of kinship is implemented at the proximate psychological level. One possibility is that kinship contributes to some general measure of relationship quality (such as ‘emotional closeness’), which in turn explains altruism. Another possibility is that the effect of kinship is independent of relationship quality. The present study tests between these two possibilities. Participants (N= 111) completed a self‐report questionnaire about their willingness to be altruistic, and their emotional closeness, to 12 family members and friends at different positions in their extended social networks. As expected, altruism was greater for family than friends, and greater for more central layers of the network. Crucially, the results showed that kinship made a significant unique contribution to altruism, even when controlling for the effects of emotional closeness. Thus, participants were more altruistic towards kin than would be expected if altruism was dependent on emotional closeness alone – a phenomenon we label a ‘kinship premium’. These results have implications for the ongoing debate about the extent to which kin relations and friendships are distinct kinds of social relationships, and how to measure the ‘strength of ties’ in social networks.     

Symptom modelling can be influenced by psychiatric categories: choices for research domain criteria (RDoC)

Psychiatric researchers typically assume that the modelling of psychiatric symptoms is not influenced by psychiatric categories; symptoms are modelled and then grouped into a psychiatric category. I highlight this primarily through analysing research domain criteria (RDoC). RDoC’s importance makes it worth scrutinizing, and this assessment also serves as a case study with relevance for other areas of psychiatry. RDoC takes inadequacies of existing psychiatric categories as holding back causal investigation. Consequently, RDoC aims to circumnavigate existing psychiatric categories by directly investigating the causal basis of symptoms. The unique methodological approach of RDoC exploits the supposed lack of influence of psychiatric categories on symptom modelling, taking psychiatric symptoms as the same regardless of which psychiatric category is employed or if no psychiatric category is employed. But this supposition is not always true. I will show how psychiatric categories can influence symptom modelling, whereby identical behaviours can be considered as different symptoms based on an individual’s psychiatric diagnosis. If the modelling of symptoms is influenced by psychiatric categories, then psychiatric categories will still play a role, a situation which RDoC researchers explicitly aim to avoid. I discuss four ways RDoC could address this issue. This issue also has important implications for factor analysis, cluster analysis, modifying psychiatric categories, and symptom based approaches.     

Orthodoxy Niches: Diversity in Congregational Orthodoxy Among Three Protestant Denominations in the United States

The organizational niche, a fruitful concept from the organizational ecology literature, frames this study on the diverse orthodoxy of congregations within the same denomination. Congregations diversify along a conservative‐to‐liberal continuum, which lessens niche overlap with nearby congregations in their denomination. Pastors and priests in United Methodist and Episcopal congregations in three U.S. regions were able to locate their congregations (and other congregations in their denomination in close proximity) along this conservative‐to‐liberal continuum, an indication that orthodoxy distinctions were important to congregational identity. In comparison, Assemblies of God congregations showed little intradenominational diversity in orthodoxy, since sectarian boundaries narrow their niche. Theoretical and methodological implications of this intradenominational diversity are explored.     

Keeping an eye on the truth? Pupil size changes associated with recognition memory

During recognition memory tests participants' pupils dilate more when they view old items compared to novel items. We sought to replicate this "pupil old/new effect" and to determine its relationship to participants' responses. We compared changes in pupil size during recognition when participants were given standard recognition memory instructions, instructions to feign amnesia, and instructions to report all items as new. Participants' pupils dilated more to old items compared to new items under all three instruction conditions. This finding suggests that the increase in pupil size that occurs when participants encounter previously studied items is not under conscious control. Given that pupil size can be reliably and simply measured, the pupil old/new effect may have potential in clinical settings as a means for determining whether patients are feigning memory loss.     

The Changing Values of Children and Preferences Regarding Family Size in South Africa

Cette recherche élargit à un contexte africain avec la problématique suivante les études en cours sur les relations entre les générations et les valeurs attribuées aux enfants: dans quelle mesure la structure des valeurs projetées sur les enfants (VOC) repérée dans des études antérieures peut‐elle être retrouvée en Afrique du Sud et quelles sont les préférences des femmes concernant la taille des familles petite, nombreuse et idéale. L’échantillon était constitué de trois cohortes de femmes noires sud‐africaines originaires de la province de Limpopo. Des analyses factorielles ont montré que les dimensions de la VOC apparue en Afrique du Sud étaient un agrégat de différentes valeurs. Ont été isolées comme dimensions relatives au désir d’enfants Social/Emotionnel et Traditionnel/Utilitaire. Pour ce qui est des motifs expliquant le choix de ne pas avoir d’enfants sont apparus l’enfant comme source de contraintes et les contraintes que constitue le fait d’avoir un enfant. Les comparaisons entre les générations montrent des variations dans l’importance des dimensions des valeurs accordées aux enfants et dans les préférences concernant la taille de la famille. Les valeurs dont les enfants sont porteurs pour les jeunes mères étaient liées au nombre d’enfants que ces femmes avaient et à leurs préférences relatives à la taille de la famille. La discussion sur les résultats tient compte de l’évolution du contexte sociopolitique de l’Afrique du Sud. This study extends the ongoing studies on values of children and intergenerational relations into an African context with the following key questions: To what extent can the structure of values of children (VOC) identified in previous studies be found in South Africa and what are women's preferences regarding the size of small, large, and ideal families? The sample consisted of three cohorts of Black South African women from the Limpopo Province. Factor analyses showed that the dimensions of VOC found in South Africa are a conglomeration of different values. Identified dimensions were Social/Emotional and Traditional/Utilitarian with respect to reasons for wanting children. Regarding reasons for not wanting children, Child as Source of Constraints and Constraints to Have a Child were identified. Intergenerational comparisons showed variations in the importance of value of children dimensions and in preferences regarding family size. Values of children of younger mothers were related to the number of children these women had and to their preferences regarding family size. The findings are discussed within the changing socio‐political context of South Africa.     

Immigrant Youth: Acculturation, Identity, and Adaptation

Cet article présente plusieurs des principaux résultats d’une grande étude internationale sur l’acculturation et l’adaptation de jeunes immigrés (âgés de 13 à 18 ans) qui se sont implantés dans treize pays (N = 5,366); il y est adjoint un échantillon de jeunes nationaux (N = 2,631). La recherche s’appuyait sur trois questions centrales: comment les jeunes migrants gèrent‐ils le processus d’acculturation? Comment parviennent‐ils à s’adapter? Et y a‐t‐il un lien manifeste entre la forme d’acculturation et le succès de l’adaptation? L’analyse en clusters déboucha sur quatre profils d’acculturation: intégrateur, ethnique, national et diffus. L’analyse factorielle de cinq variables d’adaptation mit en évidence deux types d’adaptation: psychologique et socioculturel. Il existe une forte relation entre la façon dont les jeunes s’acculturent et leur adaptation: ceux qui présentent un profil intégrateur bénéficient des meilleurs indicateurs d’adaptations psychologique et socioculturelle alors que ceux souffrant d’un profil diffus ont les pires. Entre les deux, le profil ethnique présente une adaptation psychologique relativement bonne et une adaptation socioculturelle plutôt pauvre, tandis que le profil national a une adaptation psychologique relativement pauvre et une adaptation socioculturelle légèrement négative. Cette configuration de résultats fut en grande partie retrouvée à travers une modélisation en équation structurelle. Les conséquences pour l’implantation des jeunes immigrés sont claires: ils devraient être encouragés à préserver l’appartenance à leur culture d’origine tout en établissant des liens étroits avec la société d’accueil. This paper reports some of the main findings from a large international study of the acculturation and adaptation of immigrant youth (aged 13 to 18 years) who are settled in 13 societies (N= 5,366), as well as a sample of national youth (N= 2,631). The study was guided by three core questions: How do immigrant youth deal with the process of acculturation? How well do they adapt? Are there important relationships between how they acculturate and how well they adapt? Cluster analysis produced four distinct acculturation profiles: integration, ethnic, national, and diffuse. Factor analysis of five adaptation variables revealed two distinct forms of adaptation: psychological and sociocultural. There were substantial relationships between how youth acculturate and how well they adapt: those with an integration profile had the best psychological and sociocultural adaptation outcomes, while those with a diffuse profile had the worst; in between, those with an ethnic profile had moderately good psychological adaptation but poorer sociocultural adaptation, while those with a national profile had moderately poor psychological adaptation, and slightly negative sociocultural adaptation. This pattern of results was largely replicated using structural equation modeling. Implications for the settlement of immigrant youth are clear: youth should be encouraged to retain both a sense of their own heritage cultural identity, while establishing close ties with the larger national society.     

Identity, Reasoning, and Emotion: An Empirical Comparison of Three Sources of Moral Motivation

Prior research on moral motivation has primarily emphasized moral reasoning and moral emotion; however, identity may also play an important role. Therefore, the purpose of the present study was to examine the relative importance of prosocial identity, prosocial moral reasoning, and empathy in predicting prosocial behavior. The sample included 91 university students, ages 19–35 years (M=21.89; SD=3.01; 80% European American; 65% female). Prosocial identity and empathy, but not prosocial moral reasoning, were positively associated with overall prosocial behavior. Exploratory analyses examined how these three sources of prosocial motivation differentially related to six forms of prosocial behavior. Results suggest the importance of considering the roles of all three sources of moral motivation.     

History Assessments of Thinking: A Validity Study

This article reports a validity study of History Assessments of Thinking (HATs), which are short, constructed-response assessments of historical thinking. In particular, this study focuses on aspects of cognitive validity, which is an examination of whether assessments tap the intended constructs. Think-aloud interviews with 26 high school students were used to examine the thinking elicited by 8 HATs and multiple-choice versions of these tasks. Results showed that although both HATs and multiple-choice items tapped historical thinking processes, HATs better reflected student proficiency in historical thinking than their multiple-choice counterparts. Item format also influenced the thinking elicited, with multiple-choice items eliciting more instances of construct-irrelevant reasoning than the constructed-response versions. Implications for history assessment are discussed.
