15 只大鼠执行标准径向臂迷宫任务（实验 1）和修改后的任务（实验 2），该任务包含一组强制选择和完成迷宫之前的 15 分钟保留间隔。除了径向臂迷宫中选择的标准测量之外，还测量了手臂的方向，并将其视为构成“微观选择”决策。老鼠进行了研究，但拒绝了许多手臂。开发了一种选择模型，其中假设有关手臂的选择决策是独立做出的，并且微选择不会有选择地引导至诱饵手臂。该模型的表现几乎与老鼠一样好。这些结果对径向臂迷宫中的选择行为由认知图引导的理论提出了重要的限制。
Fifteen rats performed in a standard radial-arm maze task (Experiment 1) and in a modified task with a set of forced choices and a 15-min retention interval prior to completion of the maze (Experiment 2). In addition to the standard measure of choice in the radial-arm maze, orientation toward arms was measured and considered to constitute go–no-go “microchoice” decisions. Rats investigated but rejected many arms. A model of choice was developed in which it was assumed that choice decisions about arms were made independently and that microchoices were not selectively guided toward baited arms. The model performed nearly as well as the rats. These results place important limitations on the theory that choice behavior in the radial-arm maze is guided by a cognitive map.
