Three aspects of the self(private, public, collective) with different probabilities in different kinds of social environments were sampled. Three dimensions of cultural variation (individualism--collectivism, tightness-looseness, cultural complexity) are discussed in relation to the sampling of these three aspects of the self. The more complex the culture, the more frequent the sampling of the public and private self and the less frequent the sampling of the collective self. The more individualistic the culture, the more frequent the sampling of the private self and the less frequent the sampling of the collective self. Collectivism, external threat, competition with outgroups, and common fate increase the sampling of the collective self. Cultural homogeneity results in tightness and in the sampling of the collective self. The article outlines theoretical links among aspects of the environment, childrearing patterns, and cultural patterns, which are linked to differential sampling of aspects of the self. Such sampling has implications for social behavior. Empirical investigations of some of these links are reviewed.
