Subclaims¶

q3 i3 Simple-effects analysis showed a significant accuracy difference between high and low flexibility groups after rule acquisition only (η²p = 0.271). → Feng X 2020 q3 i3 In the post-learning stage, the main effect of group on accuracy was significant (η²p = 0.240). → Feng X 2020 (2)

Evidence¶

Feng X 2020¶

Feng X, Perceval GJ, Feng W and Feng C (2020) High Cognitive Flexibility Learners Perform Better in Probabilistic Rule Learning. Front. Psychol. 11:415. https://doi.org/10.3389/fpsyg.2020.00415

q3 · i3 · associational · r2

Mixed-measures ANOVA on accuracy in the coin-searching task (2 flexibility groups × 4 probability pairs × 2 learning stages). The group difference in accuracy emerged "after rule acquisition only" (F(1,34) = 12.651, p < 0.05, η²p = 0.271).

"An analysis of simple effects of high/low flexibility group and learning stage on accuracy showed a significant difference between the two groups after rule acquisition only [ F(1,34) = 12.651, p < 0.05, η2 p = 0.271]"

q3 · i3 · associational · r1

Post-learning-stage ANOVA on accuracy across the four probability pairs. A significant main effect of group (F(1,37) = 11.662, p < 0.05, η²p = 0.240) accompanied the probability-pair effect (η²p = 0.350).

"We observed a significant main effect of probability pair [ F(3,111) = 19.889, p < 0.001, η2 p = 0.350] and group [F(1,37) = 11.662, p < 0.05, η2 p = 0.240]."

Discussion¶

Related Claims¶

• High cognitive flexibility learners identify the correct probabilistic rule more often than low flexibility learners — related
• After rule learning, low flexibility learners show latency differences across probability conditions while high flexibility learners do not — related
• High and low flexibility learners reach rule acquisition at similar points, so flexibility does not speed rule acquisition in this task — related
• Rule learners report higher confidence in their described rules than non-learners, but confidence does not differ within flexibility groups — related
