Validation procedure. (a) Framewise displacement (FD). (b) Intersubject correlation (ISC). Results are shown for the five experimental groups: audiovisual (AV), audio-only (A), video-only (V), congenitally blind (CB), and congenitally deaf (CD). For typically developed groups, ISC peaks were observed in the left superior temporal gyrus (STG) for AV (r = 0.45; MNIxyz: −65, +14, +1), in the right lateral occipital cortex (LOC) for V (r = 0.40; MNIxyz: +52, −74, −2), and in the left STG for A (r = 0.41; MNIxyz: −65, −11, +4). For sensory-deprived groups, ISC peaked in the right STG for CB (r = 0.27; MNIxyz: +64, −8, −2) and in the right LOC for CD (r = 0.40; MNIxyz: +49, −74, +1). The color scale in the figure was adjusted to match the group with the lowest ISC values.
