LG's contour integration threshold improved to age-level performance. (A) Illustration of contour detection in noise stimulus, where a contour made of Gabor patches (circular shape) embedded in randomly oriented patches was measured as a function of background element density to target spacing ratio. See Methods for more details. (B) LG's performance pre-training to more than 4 years post-training. The x-axis shows the time since the onset of training (arrow below x-axis indicates the training duration), and the y-axis denotes the contour integration thresholds. Light and dark gray lines indicate performance of children aged 5–6 years, and normal adults. Error bars indicate SEM.
