Feelings-of-Warmth Increase More Abruptly for Verbal Riddles Solved With in Contrast to Without Aha! Experience.

We computed a 3 × 2 repeated-measures ANOVA with factors ROUND(third-to-last, second-to-last, last) and AHA(aha, no aha) to compare mean FoW ratings, and found a highly significant main effect for ROUND [ F (2,52) = 132.27, p < 0.001, ε G-G =0.845, η p 2 =0.836, power G-G =1.0], no main effect of AHA [ F (1,26) = 1.05, p = 0.315, η p 2 = 0.039, power = 0.167], and a highly significant interaction [ F (2,52) = 15.63, p < 0.001, ε G-G =0.642, η p 2 =0.375, power G-G =0.988].
