Subclaims¶

q3 i? Type II bias (Broc) showed a significant age × age group interaction (F(1,52) = 11.5, p = .001), driven by a positive correlation with age in adolescents (r = .41, p = .028) and a negative correlation in adults (r = −.49, p = .008). → Weil L.G. 2013

q3 · i? · associational · r2

Univariate ANOVA of Broc in the same sample found a significant main effect of age group (F(1,52) = 10.50, p = .002) with higher Broc in adolescents; "the ratings tended to be biased towards greater confidence over the course of adolescence and declined in adulthood".

"the interaction effect was driven by a positive correlation between age and Broc in the adolescents (r = .41, p = .028), and a negative correlation in the adults (r = −.49, p = .008)."

• Metacognitive ability increases with age during adolescence and plateaus in adulthood when task performance is held constant — related
• The adolescent improvement in metacognitive ability is independent of perceptual task performance, which was clamped and uncorrelated with age — related
