a Average navigator efficiency for No Feedback and Feedback Game image acquisitions. Use of the feedback game significantly increased navigator efficiency compared to no feedback. The solid red line indicates the mean of each group. b Average navigator efficiency vs age for No Feedback (NF) and Feedback Game (FG) image acquisitions. There was no correlation between navigator efficiency and age for either no feedback (r = -0.07, p = 0.63) or feedback game (r = 0.14, p = 0.32) acquisitions. The solid lines indicate the line of best fit for each group
