q3 i? Across all participants, and separately within males and females, cortisol change did not significantly predict perseverative errors. → Shields Grant S. 2016

Evidence¶

Shields Grant S. 2016¶

Shields Grant S., Trainor Brian C., Lam Jovian C. W., Yonelinas Andrew P. (2016). Acute Stress Impairs Cognitive Flexibility in Men, Not Women. Stress. https://doi.org/10.1080/10253890.2016.1192603

q3 · i? · causal · r2

Secondary null analysis in the randomized experiment relating cortisol change to log-transformed perseverative errors. The article reports only p-values ("p=.781", "p=.205", "p=.844") with no effect size.

"Across all participants, changes in cortisol (post-manipulation minus baseline) did not predict perseverative errors, p=.781; changes in cortisol did not predict perseverative errors when restricting analyses to only males, p=.205 or only females, p=.844."

Discussion¶

Learner Variables¶

• Executive Function — predictor: learners who differ on it differ in outcomes
