1. Step down test to assess fear
​
One at a time, each mouse will be placed on a small block (2x4" and .5" high) in the middle of a large box. The time it takes for it takes to step down from the block is recorded. A second block will be placed on top of the first and the time it takes for it to step off is recorded. This is repeated until either a. the mouse refuses to step down within 2 minutes, or b. the maximum allowable height of 12" is reached.
