Abstract
Zusammenfassung: Das Konzept der verwandtschaftlichen Orientierung bezieht sich auf einen evolvierten Mechanismus der Bevorzugung von genetisch verwandten gegenüber nichtverwandten und genetisch näher verwandten gegenüber genetisch entfernter verwandten Personen. Die verwandtschaftliche (nepotistische) Orientierung wird durch die Korrelation zwischen genetischer Verwandtschaft und emotionaler Nähe innerhalb individueller sozialer Netzwerke indiziert (Neyer & Lang, 2003). In dieser Studie wurde die 4-Jahresstabilität der nepotistischen Orientierung mit unterschiedlichen Methoden in 2 unabhängigen Stichproben untersucht (489 junge Erwachsene und 206 Hochbetagte im Durchschnittsalter von 28 bzw. 84 Jahren). Die Befunde stützen die Annahme einer relativ stabilen nepotistischen Orientierung als evolvierter psychologischer Adaptation, die aber auf individueller Ebene angesichts der hohen Plastizität des menschlichen Sozialverhaltens je nach Umweltbedingungen einigen Schwankungen unterliegt.
Abstract: The concept of kinship orientation (nepotism) refers to the tendency to emotionally prefer kin over non-kin, and closer kin over less close kin. This tendency can be operationalized by the correlation of differential genetic relatedness with emotional closeness within individual social networks (Neyer & Lang, 2003). This research investigated the 4-year stability of nepotism in 2 independent samples using different methods (489 young and 206 older adults aged 24 and 84 years, respectively). Mean level of nepotism was stable, and the rank-order stability was moderate. The findings support the assumption of nepotism as evolved psychological adaptation, which despite the plasticity of social relationships remains stable throughout adulthood, although being malleable at the individual level.
