  • For the visual stimulation task, face-selective activation defined for face ROIs, object-selective activation defined for object ROIs and place-selective activation defined for place ROIs. The OGB was defined relative to each participant’s sex as a difference score in the magnitude of activation in response to the male and female face recognition blocks (e.g., for a female participant female > male blocks). The t tests evaluated a difference in magnitude of this relative OGB between the two sexes. Bolded p values surpassed the FWE correction of p < 0.004. All t tests were independent-samples two-tailed tests.
