Figure 2. Identity and Expression Matching Task.

Figure 2.

A. Images of 8 different facial identities and 4 different expressions (happy, fearful, angry, and neutral) from 3 different viewpoints (left, front, and right) were used as stimuli. B. Depiction of the trial structure – each trial began with a 100ms fixation cross, followed by the presentation of three faces in a triangle format for 2s, during which participants were to indicate which of the two bottom faces (or neither) matched the top face either on identity or expression (in separate runs). C. Box and whisker plots showing performance accuracy for identity and expression matching for control participants in blue and MBS individuals in red. MBS individuals had similar performance as control participants on the identity matching task but worse performance on the expression matching task (*p < 0.01; ns: no significant difference; chance performance on this task = 33%).
