Collection: Hierarchical competitions subserving multi-attribute choice

Description: Contrast map from psychophysiological interaction analysis (PPI), at time of decision. Seed region is bilateral IPS, extracted from attribute relevance competition. Psychological regressor reflects difference between trials where stimulus attribute is deemed 'relevant', and response attribute is deemed 'relevant'. Voxels with positive values show more functional connectivity to IPS when stimulus is relevant than response; voxels with negative values show the converse. See figure 6 of paper.
