Figure 3. Duration of Gaze Fixation. Figure shows average duration of gaze fixation (in milliseconds, vertical axis) for the six gamers (from the Baseline condition of the Gap-Overlap Task) before (light) and after (dark) training. Error bars represent average standard error for pre- and post-training fixation duration. Four of 6 gamers significantly improved the duration of gaze fixation (greater than 2 standard errors compared to a sample of 23 typical children mean age 11). Three of these who had shorter than typical fixation duration improved into the typical range marked by dashed lines representing upper and lower confidence limits of the typical sample from Miller et al (Miller, Chukoskie et al. 2014).
