Subclaims¶

q3 i3 Only the low flexibility group showed significantly different post-learning latencies across probability pairs (η²p = 0.343), responding faster to larger (2/3) than smaller (1/3) probability differences (Cohen's d = 0.24). → Feng X 2020

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 · r1

Simple-effects latency analysis in the coin-searching task: "only the low flexibility group had significantly different latencies in the different probability pairs" (F(3,32) = 5.571, p < 0.05, η²p = 0.343).

"Simple effects analysis of the four probability pairs for the two flexibility groups showed that only the low flexibility group had significantly different latencies in the different probability pairs [F(3,32) = 5.571, p < 0.05, η2 p = 0.343]."

q3 · i1 · associational · r1

Paired t-test within the low flexibility group on post-learning latencies: 1/3 difference M = 498.20 ms vs 2/3 difference M = 419.97 ms, t(11) = 3.406, p < 0.05, Cohen's d = 0.24.

"A paired sample t-test showed a significant difference between 1/3 ( M = 498.20 ms, SD = 176.54 ms) and 2/3 ( M = 419.97 ms, SD = 135.34 ms) probability differences [ t(11) = 3.406, p < 0.05, Cohen’s d = 0.24]. After successful rule learning, the low flexibility subjects responded faster to stimuli with a higher probability difference."

Discussion¶

Related Claims¶

• High cognitive flexibility learners identify the correct probabilistic rule more often than low flexibility learners — related
• High cognitive flexibility learners show significantly higher accuracy than low flexibility learners only after rule acquisition in probabilistic rule learning — related
• Rule learners report higher confidence in their described rules than non-learners, but confidence does not differ within flexibility groups — related
• High and low flexibility learners reach rule acquisition at similar points, so flexibility does not speed rule acquisition in this task — related
