The article investigates whether more socially restrictive societies provide more outlets for aggression. These authors operationalized restrictiveness with the presence of sorcery and unilineal kinship structure; the two outlets for aggression examined were occurrence of warfare and games of physical skill. Results suggest an association between these variables, though unilineal kinship structure was the better predictor of the existence of warfare.

This article tests some conditions that may lead to the emergence of unilineal descent, focusing on unilocality and warfare. Unilineal descent is thought to be likely in a unilocal society without a centralized political system that is experiencing intra- or inter-societal warfare. The authors also posit that a "clan" system usually develops prior to a "lineage" system.

This article examines the relationships between game types (physical, strategy, and chance) and social, religious, and geographic variables. Hypotheses are supported.

This study focuses on the development of unilineal descent, reviewing previous theories and testing additional factors to explain the relationship between unilineal descent and unilocal residence. Results suggest four key factors leading to a low association between these two variables: insufficient alternatives to unilocal residence rule, instability of communal composition, absence of sedentary settlement pattern, and small average community size. A model linking all variables from the paper is presented.

This study replicates the study of games conducted by Roberts, Arth and Bush (1959) using new data. Findings support the results of the original study, suggesting that games of strategy are related to social complexity and games of chance are related to games of physical skill.

This article tests hypotheses related to kinship terms, cousin marriage, and descent rules. Omaha, Crow, Eskimo, and Iroquois systems are each significantly associated with different kinship rules. Material from Northern Ghana is also considered.

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