Tolman trained rats to run down a straightaway, and subsequently make several turns until finally reaching a goal box baited with food. After the rats learned this task, the maze was altered. The main straightaway was blocked. However, there were many alternate paths radiating in all directions from the start box. The goal box remained in the same location relative to the start box, and one of the alternate paths led directly to it. Tolman found that rats:
