(A) The +-maze has two Start arms (East or West). On each trial, the unused Start arm is blocked. The animal chooses between two possible Goal arms (North or South), only one of which is rewarded. (B) The +-maze provides 4 different tasks. Two spatial tasks are solved by entering the goal arm in one spatial location (North or South). Two response tasks are solved by executing a specific body turn response (Right or Left) to enter a goal arm. A strategy switch occurs when the task is changed from spatial to response or vice versa. A spatial reversal occurs when the task is changed from one spatial task to the other.
