Acute stress enhances certain cognitive functions and working memory in the brain.
the verdict
REFUTED
the evidence says no
confidence 10/100
The claim that acute stress enhances cognitive functions and working memory is refuted by psychological and neuroscientific literature, which consistently demonstrates that stress impairs prefrontal cortex-mediated functions such as working memory and executive control.
