Perceptual learning of motion segregation affects spatial suppression. a Motion segregation performance as a function of the training session. Data were fit with an exponential function. Error bars are s.e.m. b Comparison of pre- and post-training motion direction discriminations at high contrast. Black lines are descriptive model fits to the post-training data (see “Methods” section), with the solid line indicating the trained motion direction. Gray lines are fits to the pre-training data. For clarity, pre-training thresholds are omitted and can be seen in Fig. 5a. Error bars are s.e.m. c The relationship between the amount of perceptual learning and the resultant change in spatial suppression strength for the trained motion direction. Error bars are 95% CI, revealing significant learning in 3 observers. The empty circle shows the average overall observers, with s.e.m as error bars. d Same as (b), except only showing data for observers who exhibited significant perceptual learning. For comparison, data for young adults is replotted from Fig. 5b (averaged over motion direction). Note that the y-axis is larger than in (b) to accommodate young adult data. e Same as (b), but for low contrast stimuli
