The authors examined same- and cross-gender friendship norms in a sample of 135 adults (average age 73 years). Participants evaluated a friend's behavior, quantitatively and qualitatively, in vignettes in which the friend's gender was experimentally manipulated. Gender often significantly, though modestly, influenced normative evaluations. Women frequently had higher expectations of friends tha...

Social attitudes toward women vary significantly across societies. This chapter reviews recent empirical research on various historical determinants of contemporary differences in gender roles and gender gaps across societies, and how these differences are transmitted from parents to children and therefore persist until today. We review work on the historical origin of differences in female lab...

Musical enculturation is a complex, multifaceted process that includes the development of perceptual processing specialized for the pitch and rhythmic structures of the musical system in the culture, understanding of esthetic and expressive norms, and learning the pragmatic uses of music in different social situations. Here, we summarize the results of a study in which 6-month-old Western infan...

The aim of this study was to identify factors affecting HIV risk reduction among 150 Black and 150 White South Africans chosen by systematic random sampling. Main outcome measures included sexual behavior and condom use, knowledge about correct condom use, intention of condom use, behavioural norms, attitudes, normative beliefs, and subjective norms about condoms, HIV/AIDS health beliefs, and H...

This article describes cross-cultural research on the relation between how people conceptualize nature and how they act in it. Mental models of nature differ dramatically among populations living in the same area and engaged in similar activities. This has novel implications for environmental decision making and management, including common problems. The research offers a distinct perspective o...

What are the origins of cultural differences in conformity? The authors deduce the hypothesis that these cultural differences may reflect historical variability in the prevalence of disease-causing pathogens: Where pathogens were more prevalent, there were likely to emerge cultural norms promoting greater conformity. The authors conducted four tests of this hypothesis, using countries as units ...

Driven by intergroup competition, social norms, beliefs, and practices can evolve in ways that more effectively tap into a wide variety of evolved psychological mechanisms to foster group-beneficial behavior. The more powerful such evolved mechanisms are, the more effectively culture can potentially harness and manipulate them to generate greater phenotypic variation across groups, thereby fuel...

We propose semantics for the manipulation of sample values and metadata for scientific data. Our approach uses domain knowledge from an ontology; computational knowledge about dimensions, units, coordinate systems, etc; and cultural and linguistic norms. It recombines annotated values with specialized operators. This semantics does several types of dynamic error checking and results in “selfdoc...

Building on a recent work of Harrison, Armstrong, Harrison, Iverson and Lange which suggested that Wechsler Adult Intelligence Scale–Fourth Edition (WAIS-IV) scores might systematically overestimate the severity of intellectual impairments if Canadian norms are used, the present study examined differences between Canadian and American derived WAIS-IV scores from 861 postsecondary students atten...

Sociosexual norms, as well as marital patterns, vary widely across human history and culture. Yet, humans share an evolved psychobiology of sexual motivation that reliably leads to procreation through incentivizing sexual activity. We predicted that in socially monogamous societies with conservative norms for sexual behavior, the interaction of sexual motivation and strong discouragement of non...
