From: Asymmetric interference between the perception of shape and the perception of surface properties Journal of Vision. 2009;9(5):13. doi:10.1167/9.5.13 Figure Legend: Results for each judgment in each task (width: width is the relevant attribute, length is the irrelevant attribute; length: length relevant and width irrelevant; shape: width or length relevant, shading irrelevant; shading: shading relevant, width or length irrelevant) from Experiment 3. Light bars represent baseline blocks, where only the relevant attribute varies, and dark bars represent filtering blocks, where both the relevant and irrelevant attributes vary. All statistical comparisons are between the absence versus the presence of variation on the irrelevant attribute for each task (i.e., between the light and the dark bars for each task). Results are based on data from 12 participants, in a repeated-measures design. Error bars indicate 95% confidence intervals derived using the mean square error term from the repeated-measures analyses of variance. (A) Results for participants' response latencies in the Shape-only task (width and length judgments) and the Shape–Shading task (width or length and shading judgments). * p < 0.05; ** p < 0.01. (B) Results for the number of errors committed in both tasks of Experiment 3 (ms = milliseconds).
