Experimental design. In two counterbalanced sessions, participants were immersed in a VR scenario (VR exposure) where they either observed the scenario from a 1PP and performed visuomotor exercises congruent with the female character’s movements (1PP; top left), or observed the scenario from a 3PP and performed visuomotor exercises congruent with the virtual camera’s movements (3PP; bottom left). In both sessions, participants were subsequently moved to an MRI scanner, where they watched a continuous 3D video from 1PP showing a domestic violence situation in which a male aggressor approached the viewer and entered their personal space (right).

Boxplots of VR questionnaire data. Left, The boxplots show the medians, interquartile ranges, maximum and minimum (as indicated by the stems) and outliers of the questionnaire scores that addressed the subjective experience of body ownership and identification for each condition (1PP, 3PP). An asterisk indicates a significant difference (FDR < 0.05). Right, The boxplots show the medians, interquartile ranges, maximum and minimum of the difference scores (1PP-3PP) for body ownership and identification.

ISC differences (permutation testing, N = 20, p[corrected] < 0.05) between perception of an identical 3D domestic violence video preceded by 1PP and 3PP exposure. Voxels that showed significantly higher ISC after 1PP exposure than 3PP exposure are indicated in yellow (top). Voxels that showed significantly higher ISC after 3PP exposure than 1PP exposure are indicated in red (bottom).

Differences in effective connectivity between perception of an identical 3D threat video preceded by 1PP and 3PP exposure (RFX ANCOVA, N = 20, p[corrected] < 0.05). The arrows indicate the direction of the connectivity between regions that is unique for each condition.

Differences in functional connectivity between perception of an identical 3D threat video preceded by 1PP and 3PP exposure (RFX ANCOVA, N = 20, p[corrected] < 0.05).

Correlation between threat proximity and the ISC time course within each ROI in the 1PP (dark gray) and the 3PP (light gray) session. An asterisk indicates a significant relationship between threat proximity and ISC (FDR < 0.05).
