Treating TOI as a categorical variable, we found a marginally significant effect of TOI category on whether participants believed practicing skills changes a person’s brain [ F (2,190) = 4.79, p = 0.009, η 2 = 0.038] Tukey contrasts revealed a significant difference only between the incremental and the entity theorists [ t (112) = 2.77, p = 0.02].
