Subclaims¶

q3 i? An Audience × Age group interaction was found in bilateral frontal, parietal, occipito-temporal and preSMA clusters; adolescents activated these regions more when observed, adults showed the reverse pattern. → Dumontheil Iroise 2016

Evidence¶

Dumontheil Iroise 2016¶

Dumontheil Iroise, Wolf Laura K., Blakemore Sarah-Jayne. (2016). Audience effects on the neural correlates of relational reasoning in adolescence. Neuropsychologia. https://doi.org/10.1016/j.neuropsychologia.2016.05.001

q3 · i? · causal · r2

Voxel-wise ANOVA within the functionally defined relational-integration network in the fMRI study found significant Audience × Age group interaction clusters; follow-up paired t-tests showed "adolescents activated these regions more when being observed by the Peer", while most adolescent effects survived Bonferroni correction and adult effects did not.

"Paired t-tests ran on mean parameter estimates from the nine Audience x Age group clusters showed a consistent pattern in all clusters: adolescents activated these regions more when being observed by the Peer relative to when Alone, while adults showed the reverse effect"
