RSA analysis for the Experiment 1. A) Shape correlation model for both the shape color and background color tasks. The model assumes a perfect sensitivity to the availability of shape information. B) Correlation with model is plotted as a function of ROI, separately for each task, pathway, and hemisphere, averaged across participants. Top plus signs indicate significant correlations with the shape model for the shape task. Bottom plus signs indicate significant correlations for the background task. Asterisks indicate significant correlation difference between tasks. Error bars represent the standard error of the mean. The gray bars represent the noise ceiling for each ROI. This indicates the reliability of correlational patterns within each ROI, approximating the upper limit of correlations between fMRI and the shape model, considering the inherent noise in the data.
