Supplementary Figure 2: Creation and summary of subjective DM in study 1
From: Neural pattern similarity reveals the inherent intersection of social categories
Study 1 subjective DM creation and summary (N = 17). (a) Mouse-trajectories were used to compute similarity vectors of each condition to the 7 main categories (e.g., trajectory-deviation towards Angry vs. Happy measures similarity to each category). Dissimilarity between all 12 conditions was computed as correlational distance (1 – Pearson r) between each of their vectors (see Online Methods). An example computation finding Happy-Asian-Females to be more similar to Happy-Asian-Males than Angry-Asian-Males is depicted. For ease of understanding, similarity (Pearson r) rather than dissimilarity (1 – Pearson r) values are depicted. (b) The resulting 12×12 subjective DM. (c) Means and (d) variability (SD) of the subjective 7×7 DM showing similarity of the 7 main categories underlying the subjective 12×12 DM.
