在径向臂迷宫中对大鼠进行测试，以确定一只大鼠所做的空间选择是否会影响另一只大鼠随后的空间选择。在一个自由选择的过程中，大鼠表现出增加的倾向，选择的位置，最近被选择的觅食伙伴，但倾向于访问的觅食伙伴访问过的位置。强迫选择程序被用来更好地控制社会刺激和大鼠之间的相互作用。在某些条件下，如果观察到另一只大鼠选择该位置，则在受试大鼠的选择序列中选择较晚的位置。气味和其他老鼠来访的其他物理痕迹被排除在这种影响的解释之外。结果表明，工作记忆的存在，由一个熟悉的同种访问的位置。
Pairs of rats were tested in a radial-arm maze to determine whether the spatial choices made by one rat affect the subsequent spatial choices of the other rat. In a free-choice procedure, rats showed an increased tendency to choose the location that had most recently been chosen by a foraging partner but a decreased tendency to visit locations that the foraging partner had visited earlier. Forced-choice procedures were used to better control the social stimulus and the interactions between the rats. Under some conditions, locations were chosen later in the choice sequence of a subject rat if another rat had been observed choosing that location. Odor and other physical traces of the other rat's visits were ruled out as explanations for this effect. The results demonstrate the existence of working memory for locations visited by a familiar conspecific.
