This article examines the "sexual conflict" hypothesis which predicts that male genital mutilation should be associated with polygyny and a reduction in the frequency of extramarital sex. Male genital mutilation (MGM) rituals should be highly public and facilitate access to social benefits. Support for these assumptions is provided.

Ikat and warp weaving techniques have a long history in Southeastern Asia and tend to be the most geographically widespread in the region. This researcher uses Bayesian and Neighbornet techniques to create models of phylogenetic descent and distribution of SE Asian weaving traditions. These findings do not support the theory of late Bronze Age Dong-Son descent.

Languages and weaving methods are passed down generation to generation, allowing both of them to have relatively clear phylogenies. These researchers use a Bayesian approach with Markov chain Monte Carlo methods to uncover similar but independent phylogenies for Kra-Dai languages and weaving technologies. Evolutionary differences between the two are most likely due to different rates of change: smooth change (language) and periods of burst and stasis (weaving). This study found that language phylogenies were not efficient at predicting phylogenies of technologies.

The researchers examine associations between male status and various measures of reproductive success among foraging/non-foraging, and monogamous/polygynous societies in order to test the "egalitarian hypothesis" which predicts lower status effects in hunter-gatherer groups. Contrary to this hypothesis, they find that male social status is equally significantly associated with reproductive success in foraging and nonforaging societies. Additional support is found for the "mating effort" hypothesis, which predicts that male reproductive success will be more associated with fertility than offspring mortality in polygynous societies, leading the authors to make various suggestions regarding the evolutionary mechanisms at play.

This study examines aggression in folktales in relation to child socialization variables. The author suggests that punishment for aggression and aggression anxiety are related to how aggression is portrayed in folktales. Hypotheses are supported.

This article examines the relationship between childhood experience and adult personality. This aspect of the adult personality is defined as ego strength. The emphasis of this study is mental health, maturity and the effectiveness of adult learning. Psychoanalytic theory predicts curvilinear relationships but most relationships are linear.

The relationships of aggression and crime to variables of childhood experience, adult behavior, and social structure are cross-culturally analyzed.

This article proposes that societal factors that cause anxiety concerning isolation and self-reliance leads to a preoccupation with dreams. Authors test associations between subsistence economy and marital residence and the use of dreams to seek and control supernatural powers.

This article examines the relationship between sonority and climate. Results suggest that languages spoken in warmer climates have higher levels of sonority than languages spoken in colder climates.

This study explores how differences in group autonomy are related to differences in internal group control. Results support the hypothesis and suggest that group autonomy is positively related to the manipulatory potential of the group and the control that the group has over its members.
