We used function Magnetic Resonance Imaging (fMRI) to obtain the hemodynamic brain responses during perspective modulated naturalistic movie presentations to find the influence of perception to individual’s cognitive and affective reactions. Inter-subject correlation (ISC) was used as the analysis tool and Interpersonal Reactivity Index (IRI) was used as the behavioral measurement tool. The study applied selected group ISC analysis to distinguish neural substrates related to physical, cognitive, and affective perspective-taking using naturalistic perspective modulated movie presentation. The finding helps understanding the neural mechanism of perspective taking and would be a useful for future social cognition studies.
