在空间记忆测试中检查了大鼠遵循不同食物搜索策略的能力。在赢-转移程序中，大鼠选择与刚刚选择的位置不同的位置会得到奖励，而在赢-停留程序中，它们会因为回到刚刚选择的位置而得到奖励。在第三个程序中，老鼠的每一个选择都得到了奖励。赢-转移策略学得很快，而且表现良好;赢-保持策略学得很慢，如果有的话。当每一个选择都得到奖励时，老鼠表现出更喜欢遵循胜利转移策略。大鼠在寻找食物时倾向于遵循胜利转移策略。他们能够更好地学习赢-转移程序而不是赢-停留程序。当任何一种选择都能带来回报时，他们更愿意遵循一种双赢的策略。讨论了这种胜利转移的倾向对野外食物采集的影响，以及对实验室辨别任务的影响。
The ability of rats to follow different food-searching strategies was examined in a test of spatial memory. In a win-shift procedure, rats were rewarded for choosing locations different from those just chosen, and in a win-stay procedure they were rewarded for returning to the locations just chosen. In a 3rd procedure, rats were rewarded for every choice. The win-shift strategy was learned rapidly and was performed well; the win-stay strategy was learned slowly, if at all. When every choice was rewarded, rats exhibited a preference for following a win-shift strategy. Rats were disposed to follow a win-shift strategy when searching for food. They were able to learn a win-shift procedure better than a win-stay procedure. When any choice produced reward, they preferred to follow a win-shift strategy. The influence of this win-shift disposition on food gathering in the wild, and on performance of laboratory discrimination tasks, was discussed.
