(A) The group-average subjective DM. Warmer colors represent greater dissimilarity. (B) The method by which a subject’s subjective DM was computed. In this example (Angry Male condition), MD values for the four categories (Female, Male, Angry and Happy), which reflect mouse trajectories’ attraction toward the four category responses in the mouse-tracking tasks, were used to create a response vector. Similarity in these response vectors was used to calculate pairwise similarity for the other conditions (Happy Female, Angry Female and Angry Male). In this way, face conditions that elicited similar activation of the Female, Male, Angry and Happy responses during mouse-tracking were deemed more similar in a subject’s subjective DM. (C) An illustration of our RSA procedure. Participants’ neural patterns for each condition were correlated with each other to formulate a neural DM. A subject’s own subjective DM was used to predict this neural DM (when controlling for the group-average subjective DM depicted in A).
