Mean angle of absolute error (degrees) in the cognitive map test as a function of delay condition (wakeful rest vs. perceptual task) and age group (young vs. older adults). Younger and older adults who experienced wakeful rest after learning performed significantly better than those who performed a perceptual task. Error bars show the standard error of the mean. Significance thresholds: * = p <.05, ** = p < .01, and *** = p < .001.
