RSA analysis for the diffeomorphic experiment. A) The shape correlation model applied to both the shape and color tasks. The model posits a perfect correlation between similar levels of scrambling, gradually decreasing as the scrambling levels differ more. B) Correlation with the model is graphed as a function of ROI, defined using the Wang atlas (2015), separately for each task, pathway, and hemisphere, and averaged across participants. Plus signs at the top indicate a significant correlation for the shape task, at the bottom for the color task. Asterisks signify a significant difference in correlation between the two 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.
