To reveal the nature of each significant cluster in terms of their association with VIQ, we employed voxel-by-voxel ANCOVAs to investigate the association between rGMV and VIQ within these clusters; small volume corrections were applied and corrections for multiple comparisons were performed only within each cluster.

The average postexperiment FSIQ of all subjects analyzed in the longitudinal analyses tended to be larger than the average FSIQ of all subjects analyzed using the preexperiment data (P = 0.065, 2-tailed t-test); FSIQ of the subjects who were analyzed in the longitudinal analyses was significantly increased between the pre- and postexperiments (P = 0.01, 2-tailed paired t-test).

Our hypotheses were partly confirmed and our cross-sectional studies newly revealed that the duration of TV viewing was positively correlated with rGMV in an anatomical cluster around the mPFC and the frontopolar area as well as a further increase in rGMV in the same area a few years later. But in 2010, researchersanalysed more than 300 porn scenes and found that 88% contained physical aggression. Over time, people come to associate those direct images (called reinforcers) with the pleasurable feelings. Results are shown with P < 0.025 uncorrected for visualization purposes.
