Basic Task Description
The deterministic reversal learning task is a computerized behavioral measure of reversal learning, a form of behavioral/cognitive flexibility that has been widely used in both animal and human studies (Robbins et al., 2000). This particular task version was modeled after a paradigm originally used to examine genetic associations with reversal learning in BXD strains of mice (Laughlin et al., 2011). Participants are presented with two doors and instructed that they will receive monetary rewards based on which door they choose. The initial side of reinforcement (right or left) is randomly selected by the computer. If participants select the door associated with the reward, they immediately see two quarters appear in place of the door and hear a rewarding sound (cash register noise). Reinforced selections also present a running total of earnings on the bottom of the screen. If participants select the door that is not associated with the reward, they immediate see the screen go black (except for a white outline where the door was) and hear a negative sound (loud buzzing noise). Once participants have selected the reinforced door for 5 consecutive trials, the contingencies for the doors are reversed. After the reversal, participants need to select the newly reinforced door for 5 consecutive trials. The primary dependent variable is the number of errors that are made after reversal.
