Error Goal-Gradients of Mature-Young and Aged Rats during Training in a 14-Unit Spatial Maze
16 mature-young and 16 aged rats were tested in a 14-unit spatial T-maze using distributed practice of one trial per day and differential motivation. Mature-young rats learned the maze more quickly than aged rats, and age differences increased with increasing trials. Error goal-gradients were obtained which were similar for both age groups and which were maintained over trials.
