Working spatial memory in dogs (Canis familiaris) was tested in Experiments 1 and 2 on an 8-arm radial maze. When dogs chose freely among all 8 arms containing food in Experiment 1, they learned to enter all 8 arms with progressively fewer arm visits over trials. In Experiment 2, 2 groups of dogs were forced to visit 4 randomly chosen arms on the maze and then tested for memory of these arm visits using a win-shift rule for 1 group and a win-stay rule for the other group. Dogs performed better with the win-shift rule than with the win-stay rule. In Experiment 3, reference memory was investigated by using a 4-arm maze on which 0, 1, 3, and 6 pieces of food were consistently placed on different arms. Dogs learned to visit the arms with the larger amounts before the arms with the smaller amounts. Dogs' memory capacity in these studies was found to be surprisingly low.
在实验1和实验2中，利用八臂放射状迷宫对家犬（犬属）的工作空间记忆进行了测试。在实验1中，当狗在所有八个装有食物的臂中自由选择时，它们学会了进入所有八个臂，并且随着试验次数的增加，进入臂的次数逐渐减少。在实验2中，两组狗被强制访问迷宫上随机选择的四个臂，然后一组使用赢-转换规则、另一组使用赢-保持规则对这些臂的访问记忆进行测试。狗使用赢-转换规则比使用赢-保持规则表现得更好。在实验3中，通过使用四臂迷宫研究参考记忆，在该迷宫上始终在不同的臂上放置0、1、3和6块食物。狗学会了先访问食物量多的臂，再访问食物量少的臂。在这些研究中发现狗的记忆能力出奇地低。
