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

This study relates the type of games present in a society to the level of cultural complexity. Authors use a "game-type combination scale" that categorizes societies as having: 1) games of physical skill only; 2) games of physical skill and games of chance; and 3) games of physical skill, games of chance, and games of strategy. Results show a relationship between the game-type combination scale and indicators of cultural complexity.

This study builds on a previous study of games by Roberts, Arth and Bush (1959) and offers a conflict interpretation of game involvement. Several significant relationships are observed between game type and child training variables.

Authors investigate the cross-cultural correlates of games of chance. They advance a "conflict-enculturation" model to explain why individuals choose to engage in games of chance in particular (as opposed to games of strategy or physical skill). They suggest that games of chance are linked to cultures with antecedent conflict and/or feelings of powerlessness in the presence of uncertainty; both are psychological stressors whose effects may be assuaged by play with uncertainty models in the form of games of chance.

Dopamine receptor D4 (DRD4) exhibits the largest number of polymorphisms of any dopamine receptor yet identified, and variation in DRD4 has been linked to variation in traits such as novelty-seeking and attention deficit/hyperactivity disorder. DRD4 also exhibits large variation between populations. Here, the authors test the hypothesis that natural selection acting on DRD4 may account for variation in between-population migratory patterns, using genetic and historical data from 39 populations.
