Synchronous brain activity across individuals underlies shared psychological perspectives is a functional magnetic resonance imaging study where human subjects watch a movie while being scanned. Half of the subjects were instructed to take a social perspective (forensic detective) while watching the movie, while the other half where instructed to take a non-social (as an interior decortator) perspective

[edit] Method

[edit] Experiment

Movie viewing of ten minutes of an episode of Desperate Housewives. The subjects were split in two groups:

  1. Social perspective
  2. Non-social perspective

[edit] Data acquisition

  • Brain scanning with fMRI.
  • EyeLink 1000 eye tracker for eye gaze recording.

[edit] Analysis

  • Intersubject correlations (ISC)

[edit] Results

  • Social perspective ('Detective') subjects look more on the face, whereas 'decorator' looks more at the surroundings (Figure 3A).
  • ...

[edit] Brain scanning

Brain areas with peak intersubject correlation.
