A) Individual face images were transformed towards high and low composite templates of trait variables (Extraversion, Agreeableness, Neuroticism, Physical health). The example shown is extraversion. The images used are for illustrative purposes and were not used in the experiment. B) During scanning, each block began with an instruction screen, which provided a statement and a reminder of the ratings scale. On each subsequent trial, participants had to make a judgment based on the face presented. As such, all trials in a mini-block were from the same category (e.g., extraversion), but all trials showed a different individual. C) An illustration of the population coding model of face perception that the repetition suppression design was testing. High and low trait features are presented in blue and green, respectively. Novel and repeated trials are presented in darker and lighter colours, respectively. The individuals presented in this figure gave written informed consent for these images to be used.

Error bars are 95% confidence intervals.

Percent signal change for novel compared to repeated trials in the face perception (A) and theory-of-mind network (B). Error bars are standard error of the mean. Abbreviations: r = right; OFA = occipital face area; FFA = right fusiform face area; pSTS = posterior superior temporal sulcus; TPJ = temporoparietal junction; mPFC = medial prefrontal cortex; ant. Temp. = anterior temporal.
