Human kinship, from conceptual structure to grammar

Research in anthropology has shown that kin terminologies have a complex combinatorial structure and vary systematically across cultures. This article argues that universals and variation in kin terminology result from the interaction of (1) an innate conceptual structure of kinship, homologous with conceptual structure in other domains, and (2) principles of optimal, "grammatical" communication active in language in general. Kin terms from two languages, English and Seneca, show how terminologies that look very different on the surface may result from variation in the rankings of a universal set of constraints. Constraints on kin terms form a system: some are concerned with absolute features of kin (sex), others with the position (distance and direction) of kin in "kinship space", others with groups and group boundaries (matrilines, patrilines, generations, etc.). Also, kin terms sometimes extend indefinitely via recursion, and recursion in kin terminology has parallels with recursion in other areas of language. Thus the study of kinship sheds light on two areas of cognition, and their phylogeny. The conceptual structure of kinship seems to borrow its organization from the conceptual structure of space, while being specialized for representing genealogy. And the grammar of kinship looks like the product of an evolved grammar faculty, opportunistically active across traditional domains of semantics, syntax, and phonology. Grammar is best understood as an offshoot of a uniquely human capacity for playing coordination games.     

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.     

Communication in social networks: Effects of kinship,network size,and emotional closeness

Communication is important in preventing social relationships from decaying over time. This study examined the effects of social network size, emotional closeness, and type of relationship (kinship vs. friendship) on communication patterns in the social networks of 251 women. Participants with large kin networks had longer times to last contact to both kin and friends. Participants with high levels of emotional closeness in their networks had shorter times to last contact. The effect of emotional closeness on time to last contact was greater for kin than for friends. These results demonstrate that time to last contact is closely tied to emotional closeness and suggest that the costs of maintaining kin relationships are lower than the costs of maintaining friendships.     

Evidence for kinship information contained in the rhesus macaque (Macaca mulatta) face

The ability to recognize kin is an important social skill for primates. Humans are adept at using facial similarity to recognize likely kin, and there is evidence that nonhuman primates are also able to use facial similarity to make judgments about kinship. However, if and how nonhuman primate faces actually contain kinship information remains unclear. To test whether there is objectively measurable facial similarity in related nonhuman primates, we compared facial measurements from related (paternal half-sisters) and unrelated adult female rhesus macaques (Macaca mulatta). Facial measurements were first summarized into 5 factors using a principal component analysis. Differences in these factors between the faces of related macaques were compared with differences between the faces of random unrelated macaques and of age-matched unrelated macaques. The difference in facial measurements between related macaques was significantly smaller than the difference in facial measurements of either group of unrelated macaques, constituting an objective measure of facial similarity in macaque kin. These results indicate that kinship information is contained in the rhesus macaque face and suggest that nonhuman primates may rely in part on facial similarity to distinguish kin.     

Will the real grandmother please stand up? The psychological reality of dual meaning representations

Two types of meaning representation are described, symptom and criterion, and it is argued that both have psychological status in mental representations of kinship terms. Certain symptoms, such as old age and biofocals for grandmothers, are likely indicators of grandmotherhood, but they do not reliably pick out all positive instances, nor do they indicate negative ones. Criteria specify the necessary and sufficient conditions for grandmotherhood: having a grandchild. The psychological reality of these two representations was demonstrated by asking children and adults to select kin-term exemplars from pictures in which both age and reciprocal kin symptoms are displayed, and to justify their selections. In both tasks, there was change with age away from using typical age as the sole basis for performance; older subjects selected pictures displaying reciprocal kin, and justified their choices by referring to the criterion. More important, at each age level, there was evidence for dual representation: Even subjects who selected pictures based on the age symptom often gave criterial justifications, and subjects who selected pictures based on the reciprocal kin symptom still preferred pictures displaying age symptoms in addition to the reciprocal kin.     

上下意象图式对羌族亲属词认知的影响

采用亲属词判断任务和真假词判断任务, 考查了“上下意象图式”对羌族被试认知隐含辈分关系的羌族亲属词的影响, 并通过空间识别任务检验亲属词辈份概念加工能否自动地激活空间意象图式, 引导空间注意朝向与空间意象图式一致的位置。实验1表明, 在羌族被试对羌族亲属词的认知中, 存在着“隐喻一致性效应”：高辈分的亲属词呈现在计算机屏幕的上方加工得更快, 低辈分的亲属词呈现在计算机屏幕的下方加工得更快。实验2表明, 当目标刺激的空间位置与亲属词的辈分信息一致时, 羌族被试对目标刺激的辨认速度更快。整个研究表明, 羌族亲属词隐含的辈分关系可以用垂直空间关系来理解, 并引导被试的空间注意朝向与上下意象图式一致的位置, 证明对抽象概念的理解基于感觉运动的加工, 符合概念隐喻理论的预言。     

道德两难判断中亲属关系的认知研究:来自ERPs的证据

采用事件相关电位技术,考察个体在道德两难情境下对不同亲属的加工特征及其亲属偏见效应。道德两难情境中的主人公为被试的两个亲属(父亲、叔父)和一个熟人,要求被试阅读道德两难情境故事后,对是否愿意救助故事中主人公作出判断。结果发现,直系亲属(父亲)比旁系亲属(叔父)和熟人诱发了更大的P2和LPC平均波幅,而旁系亲属与熟人之间并无显著差异。研究表明了个体对直系亲属更为关注和敏感,表现出明显的亲属偏见效应。     

Kinship and altruism: A cross‐cultural experimental study

Humans are characterized by an unusual level of prosociality. Despite this, considerable indirect evidence suggests that biological kinship plays an important role in altruistic behaviour. All previous reports of the influence of kin selection on human altruism have, however, used correlational (rather than experimental) designs, or imposed only a hypothetical or negligible time cost on participants. Since these research designs fail either to control for confounding variables or to meet the criteria required as a test of Hamilton's rule for kin selection (that the altruist pays a true cost), they fail to establish unequivocally whether kin selection plays a role. We show that individuals from two different cultures behave in accordance with Hamilton's rule by acting more altruistically (imposing a higher physical cost upon themselves) towards more closely related individuals. Three possible sources of confound were ruled out: generational effects, sexual attraction and reciprocity. Performance on the task however did not exhibit a perfect linear relationship with relatedness, which might reflect either the intrusion of other variables (e.g. cultural differences in the way kinship is costed) or that our behavioural measure is insufficiently sensitive to fine‐tuned differences in the way individuals view their social world. These findings provide the first unequivocal experimental evidence that kinship plays a role in moderating altruistic behaviour. Kinship thus represents a baseline against which individuals pitch other criteria (including reciprocity, prosociality, obligation and a moral sense) when deciding how to behave towards others.     

Altruistic Celibacy, Kin-Cue Manipulation, and The Development of Religious Institutions

Abstract. Building on a model first proposed by Gary Johnson, it is hypothesized that religious institutions demanding celibacy and other forms of altruism from members take advantage of human predispositions to favor genetic relatives in order to maintain and reinforce these desired behaviors in non‐kin settings. This is accomplished through the institutionalization of practices to manipulate cues through which such relatives are regularly identified. These cues are association, phenotypic similarity, and the use of kin terms. In addition, the age of recruits and their contact with actual kin are factors that relate to kinship recognition and that are similarly manipulated by institutions in order to reinforce altruistic behavior directed toward non‐kin. Support for this set of predictions is presented from historical and ethnographic sources on monastic life in Buddhism, Christianity, and Hinduism, as well as Islamic dervish groups, the Essenes, Shakers, and others. Potential implications of the model for understanding the development of religious institutions are preliminarily explored by reviewing Joachim Wach's model of religious developmental stages as well as some of the literature on the relationship between individualism and communalism in incipient religious organizations, in light of the kin‐cue manipulation model.     

Family Financial Pressure and Maternal and Adolescent Socioemotional Adjustment: Moderating Effects of Kin Social Support in Low Income African American Families

The moderating effect of kinship social support on the association of family financial pressure with socioemotional adjustment was examined in 200 African American mothers and adolescents. Financial pressure was positively associated with mothers’ depressive symptoms and negatively related to mothers’ optimism about the future. Financial pressure was also positively associated with adolescents’ depressive symptoms and problem behavior. Kin social support was negatively linked to mothers’ depressive symptoms and positively associated with optimism. Kin support was negatively related to adolescents’ problem behavior. Kinship support moderated the association of family financial pressure with mothers’ and adolescents’ adjustment. Positive association of financial pressure with mothers’ depression was less apparent for mothers with more compared to less kin social support. Also, negative association of financial pressure with mothers’ optimism was less apparent for mothers with more compared to less kin social support. Positive relation of financial pressure with adolescents’ problem behavior was less apparent for those with more compared to less kin social support. The need to assess the links of kin social support to other domains of family life such as marital relations is discussed.     

Selective interference in rhesus monkey (Macaca mulatta) intragroup agonistic episodes by age-sex class

Adult male interference in agonistic episodes is strongly biased against adolescent and adult male participants, whereas adult female interference is biased in favor of kin and in support of younger animals against older animals. Although natal males also are biased in favor of their kin, their selective targeting of sexually mature males is independent of kinship. Adolescent males target adult males, but only in defense of kin. This selective interference against adolescent and adult males by adult males has the potential to profoundly modify male agonistic participation in intragroup encounters after puberty. Because female support is influenced primarily by kinship, females less consistently interfere against male agonistic participants. Adult males may therefore play an important role in the socialization of male agonistic expression.     

Family reconciliation as a response to adolescent crises

Concern for adolescents who act in dangerous, life-threatening ways has heightened dramatically in recent years. Many of these adolescents appear to come from nuclear families isolated from their kinship systems. Without the mediating effects of kin, the adolescent transition can become a major crisis. Kinship systems remain cohesive when members can reconcile their beliefs about essential aspects of family functioning with the demands for adaptation during major life transitions. Reconciliation is lost when members believe that kin can no longer be trusted to insure their well-being. Kinship fragmentation ensues as family members leave the field or are excluded. Isolated nuclear families then rapidly lose the resilience to respond to life transitions without resorting to extreme, maladaptive solutions. The Systemic Crisis Intervention Program (SCIP) uses the opportunity of the crisis precipitated by the adolescent's life-threatening behavior to alter family myths that have led to network fragmentation. Crisis teams mobilize and meet with kin in four-hour gatherings to foster reconciliation and kinship system reintegration.     

亲子鉴定:科技维护家庭伦理存在的道德悖论

亲子鉴定对于维护家庭应有的婚姻观念和伦理关系的积极意义是不言而喻的;但同时也带来一系列需要引起注意的新问题,如强化了男子亲权的意义而忽视了女子亲权的意义、强化性关系的生理和血缘伦理意义而弱化了性关系的社会伦理意义,容易因诱发和助长夫妻间的不信任情绪而导致婚姻和家庭信任危机等;因此,国家和社会应当对亲子鉴定进行必要的引导和限制。     

The Colored, Eco-Genetic Relationship Map (CEGRM): A Conceptual Approach and Tool for Genetic Counseling Research

The Colored Ecological and Genetic Relational Map (CEGRM) [pronounced see-gram] is a conceptual approach and tool for presenting information about family and nonkin relationships and stories about inherited diseases in a simple, understandable form. It combines information that can be derived from pedigrees, genograms, ecomaps, and social network analysis in a single, or series of, pictorial maps based on colors and shapes. The CEGRM is based on a social systems perspective, particularly emphasizing social exchange and resource theories. The CEGRM should be particularly useful in genetic counseling research with members of suspected cancer-risk families or families with other late-onset inherited diseases. A genetic counseling client comes with a social history and context as well as a genetic one. Client decision-making in terms of reproductive plans, therapeutic intervention, lifestyle behavior and sharing or withholding of genetic information frequently becomes enmeshed with preexisting psycho-social relationships among biological kin, affinal kin (in-laws) and fictive kin (friends who act as family). The CEGRM makes it easier to compare different types of social interactions between the client and his/her significant others and among family members on the same dimensions.     

平辈亲属词语义加工中长幼概念的空间隐喻和重量隐喻——来自中国朝鲜族和汉族的证据

采用具身认知范式考察平辈亲属词语义加工中长幼概念的空间和重量隐喻,比较中国朝鲜族和汉族的长幼观念。实验1表明,中国朝鲜族人在平辈亲属词语义加工中对平辈年长亲属词的加工快于对平辈年幼亲属词的加工,并且存在着部分的上下隐喻一致性效应,平辈年幼亲属词呈现在屏幕的下方加工得快。汉族人在平辈亲属词语义加工中存在着完整的上下隐喻一致性效应:平辈年长亲属词呈现在屏幕上方加工得快,平辈年幼亲属词呈现在屏幕下方加工得快。实验2表明,"左大右小"的亲属词对促进了中国朝鲜族人对"左重右轻"天平倾斜方向的判断,表明亲属词对蕴含的长幼概念激活了重量概念,但对汉族人的天平倾斜方向判断却无显著的影响。实验3表明,"左重右轻"的天平倾斜方向促进了中国朝鲜族人对"左大右小"的朝鲜语亲属词对的年龄比较,表明重量加工激活了长幼概念,但不影响汉族人对汉语亲属词对的年龄比较。朝、汉两个民族对平辈亲属词的不同隐喻方式源于不同的文化图式,反映了两个民族的长幼文化的差异:与汉族人相比,中国朝鲜族人更重视长幼秩序,对长幼规范的要求更加严格。     

Comparison of two models of similarity judgment

The conventional multidimensional distance model of similarity judgment was compared with a new model in which component differences are weighted and then averaged. To evaluate the models, qualitative and quantitative predictions were derived from Romney and D'Andrade's (1964) componential analysis of American kinship terms, and these predictions were tested by having subjects rate the similarity (in experiment 1) and the difference (in experiment 2) between all possible pairs of 12 kinship terms. In both experiments, violations of qualitative predictions for both a simple distance model and a simple averaging model revealed that the componential analysis was not sufficient to account for the data. However the averaging model was able to account for the data when the dichotomous dimension of lineality used by Romney and D'Andrade was replaced by a continuous dimension of immediacy or closeness of kin. In contrast, no comparable elaboration under the distance model was successful. These results were discussed in terms of the likely psychological processes underlying similarity judgment.     

基诺族亲属词概念结构的特点及其成因

运用自然分类和多维标度方法,探讨基诺族中学生的亲属词概念结构特点。结果发现,基诺族亲属词概念结构有两个维度：(1)亲密程度;(2)照顾者／被照顾者。这与汉族中学生的亲属词概念结构既有相同之处,又有明显差异。这与基诺族的血缘婚制度以及马来亚式亲属制度等历史积淀有关,也与基诺族跨越式发展中他文化的渗透和主文化的变迁有关。

Social cues and verbal framing in risky choice

We examined how people use social and verbal cues of differing priorities in making social decisions. In Experiment 1, formally identical life – death choice problems were presented in different hypothetical group contexts and were phrased in either a positive or negative frame. The risk‐seeking choice became more dominant as the number of kin in an endangered group increased. Framing effects occurred only in a heterogeneous group context where the lives at risk were a mixture of kin and strangers. No framing effect was found when the same problem was presented in the context of a homogeneous group consisting of either all kin or all strangers. We viewed the framing effects to be a sign of indecisive risk preference due to the differential effects of a kinship cue and a stranger cue on choice. In Experiment 2, we presented the life – death problem in two artificial group contexts involving either 6 billion human lives or 6 billion extraterrestrial lives. A framing effect was found only in the human context. Two pre‐conditions of framing effects appear to be social unfamiliarity of a decision problem and aspiration level of a decision maker. In Experiment 3, we analyzed the direction of the framing effect by balancing the framing. The direction of the framing effect depended on the baseline level of risk preference determined by a specific decision context. Copyright © 2001 John Wiley & Sons, Ltd.     

Kin recognition loss following anesthesia in beetle larvae (Aleochara bilineata, Coleoptera, Staphylinidae)

Kin recognition is a complex cognitive process, where an individual should detect a phenotypic cue and compare it to an internal template, which might be genetically determined (i.e., innate or acquired). Kin recognition mechanisms will depend on whether previous encounters with kin are possible or not to form the individual internal template. When relatives have never met before, kin recognition is supposed to rely on recognition alleles (which allows the innate recognition of relatives bearing them), or on self-referent phenotype matching (the individual has formed a template using its own phenotype and recognizes as kin individuals which match it closely enough). Although self-referent phenotype matching is in theory the more likely explanation, it has not been possible so far to exclude experimentally the recognition alleles’ hypothesis. Here, we report that kin recognition in the solitary parasitoid larvae of Aleochara bilineata (Coleoptera; Staphylinidae) is suppressed following carbon dioxide anesthesia or chill-coma, both treatments known to cause a temporary amnesia. Treated larvae superparasitize indifferently hosts parasitized either by siblings or by non-kin larvae, while untreated larvae avoid hosts occupied by siblings. The two types of anesthesia thus suppress kin recognition, but their global effect on larvae is different. Chill-coma suppresses the ability to distinguish parasitized from unparasitized hosts and reduces parasitism rate, suggesting an aspecific impairment of sensory receptors or cognition. However, carbon dioxide narcosis only impairs kin recognition, strongly suggesting that an intact memory is necessary for kin recognition to take place. Although this study does not address the recognition alleles’ hypothesis per se, our results strongly support a self-referent phenotype matching mechanism. On the whole, kin recognition in A. bilineata larvae is effective through short-term memory, because it is affected by amnesic treatments.
