A silent emergence of culture: The social tuning effect.

Abstract

Scholars have long been concerned with understanding the psychological mechanisms by which cultural (i.e., shared) knowledge emerges. This article proposes a novel psychological mechanism that allows for the formation of cultural memories, even when intragroup communication is absent. Specifically, the research examines whether a stimulus is more psychologically and behaviorally prominent when it is assumed to be experienced by more similar versus less similar others. Findings across 3 studies suggest that stimuli such as time pressure (Study 1), words (Study 2), and paintings (Study 3) are more psychologically and behaviorally prominent when they are thought to be experienced by more (vs. less) similar others. Critically, the effect is absent when similar others are thought to be experiencing distinct stimuli from the participant (Study 3). Taken as a whole, these results are consistent with the hypothesis that stimuli which are assumed to be experienced by one's social group are more prominent in both cognition and behavior. Theoretical implications for the emergence of culture are discussed.
