小鼠与大鼠
Roger Morris博士的小鼠水迷宫提示
“由压力/奖励提供的动机与一项困难任务之间的微妙平衡。”
1998年，Roger Morris博士（不要与发明该迷宫的Richard Morris教授混淆）分享了他来之不易的小鼠实验笔记。这些笔记实用、略带幽默，至今仍很有用。我们把它们分成了若干短页面；以下是开头部分（英文原文）。
Mouse / Water maze Hints

The following notes are edited from material kindly supplied by Dr. Roger Morris.
Editor's notes:
“a) Rats are natural swimmers and if handled well will cooperate easily in Water Maze. They don't have the option to float or jump - they are solid citizens who just swim for that platform and get onto it.
b) Mice are also good swimmers, and if handled well, will also take part easily. But they are more temperamental, and they do have the option to stop swimming and just float, and to jump. These notes suggest ways to reduce stress, so your mice will feel confident, and cooperate.
”
-Richard Baker
Introduction
The swimming-pool (Morris Water Maze) is a delicate balance of motivation provided by stress/reward, and a difficult task. It is an unnatural for rodents, for whom sight is a minor sense. If the stress is too high, or the reward too slight, the task is not attempted.
