Subclaims¶

q3 i2 Men in the stress condition committed significantly more perseverative errors than men in the control condition (d=0.68). → 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 · i2 · causal · r2

Planned pairwise contrast within the randomized TSST-G experiment (Berg Card Sorting Test, log-transformed perseverative errors). The article reports the male stress-versus-control contrast with "d=0.68"; higher scores indicate worse flexibility.

"men in the stress condition (M=2.19, SE=0.15) committed significantly more perseverative errors than men in the control condition (M=1.73, SE=0.16), t(95.5)=2.04, p=.044, d=0.68"

Discussion¶

Learner Variables¶

• Executive Function — outcome: instruction changes it

Related Claims¶

• Acute stress did not significantly affect women's cognitive flexibility — related
• Acute psychosocial stress differentially affects cognitive flexibility by sex (significant Sex × Condition interaction on perseverative errors) — a broader claim this one bears on
• Changes in cortisol did not predict perseverative errors in any sex — related
• The TSST-G stress induction increased negative affect and cortisol relative to control — related
• Manipulation check: instructional condition significantly affected errors made during training, with exploratory learning producing more errors — related
