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
Group 1 of 20 healthy volunteers with 5 males and 7 females were included in the study.
The group had a mean age of 25 with a range from 19 to 38.
The study on the human subjects was approved by the Ethics Committee of the Hostpital District of Helsinki-Uusimaa
Group 2 of 13 healthy volunteers with 13 males and 8 females were included in the study.
The group had a mean age of 27.
The study on the human subjects was approved by the Ethics Committee of the Hostpital District of Helsinki-Uusimaa.
Data from two subjects in the last experiment were lost.
Movie viewing of ten minutes of an episode of Desperate Housewives.
The subjects were split in two groups:
- Social perspective
- Non-social perspective
 Data acquisition
- Intersubject correlations (ISC)
- Social perspective ('Detective') subjects look more on the face, whereas 'decorator' looks more at the surroundings (Figure 3A).
 Brain scanning
Brain areas with peak intersubject correlation.
