This paper is concerned with the variation in sexual behavior in humans. Authors test hypotheses regarding the relationships between sexual behaviors and beliefs concerning sex.

Authors hypothesize that grammatical sex gender may be related to social structural variables. Results support this hypothesis and suggest that the degree of sex bias in the social structure is associated with the relative frequency of masculine and feminine nouns in languages with sex gender.

This book chapter examines relationships between the child-training behavior of mothers and the responsibilities of both mothers and others. Child-training behavior is also examined in relation to single and multiple family dwellings.

Researchers looked at the meaning of various emotion concepts, 'emotion semantics' in an attempt to determine the patterns and processes behind meaning cross-culturally. They used maps of colexification patterns (where semantically related concepts are named with the same word), adjusted Rand indices (ARIs) which indicated the similarities of two community's network structures, and various psychophysiological dimensions to test relationships and patterns of variability /structure in emotion semantics. These methods shed light on the underlying mechanisms behind emotions, both their words and their meanings in languages across the world. Their findings show substantial difference in language families and relationships between geographic proximity of language families and subsequent variation in emotion colexification tied to an evolutionary relationship, while also finding cultural universals in emotion colexification networks with languages primarily differentiating emotions on the basis of valence and activation.

This article proposes that differences in diet may account for the presence or absence of morning sickness in a society. Data suggest that morning sickness is not a universal symptom of pregnancy, and there are significant differences in foods consumed where morning sickness does not occur, including more maize, fats, and vegetables.
