虽然有大量的证据表明社会学习和其他形式的社会影响行为，相对较少的实验分析所涉及的机制。本文回顾了一系列研究，探讨社会对空间选择的影响，在空间工作记忆范式的背景下，使用对实验室大鼠一起觅食。有一个社会联系效应-老鼠被吸引到空间位置，如果一个熟悉的同种在那里。然而，有一个抵消的趋势，以避免访问的空间位置，以前耗尽的食物由其他大鼠。后一种效应是基于对另一只大鼠先前所做选择的工作记忆。另一只大鼠先前选择的记忆可以灵活地影响随后的选择，增加或减少选择倾向，这取决于大鼠自己访问该位置所产生的空间位置内容的工作记忆。
Although there is abundant evidence for social learning and other forms of social influence on behavior, relatively little experimental analysis of the mechanisms involved is available. The present paper reviews a line of research examining social influences on spatial choice in the context of spatial working memory paradigms using pairs of laboratory rats foraging together for food. There is a social affiliation effect - rats are attracted to spatial locations if a familiar conspecific is there. However, there is a countervailing tendency to avoid visits to spatial locations that were previously depleted of food by the other rat. The latter effect is based on working memory for the choices made previously by the other rat. The memories for the previous choices of another rat can affect subsequent choices flexibly, either increasing or decreasing choice tendencies depending on working memory for the contents of spatial locations resulting from the rat's own visits to the location.
