What was done
Rhesus monkeys performed a challenging reaching task under varying incentive levels, including an unusually large jackpot reward that triggered underperformance. Researchers examined neural activity during movement preparation in the motor cortex to identify the neural mechanism behind the performance drop under high stakes.
What was found
The abstract reports no numerical values or sample sizes. Qualitatively, it reports that increasing reward drives movement preparation neural activity in the motor cortex into and then beyond a zone of optimal performance, coinciding with choking under pressure on high-reward trials.
Why it matters
This study provides a concrete neural mechanism linking high-stakes reward processing to motor cortex preparation errors, helping explain why high pressure degrades physical performance.
Limits
The study was conducted in rhesus monkeys rather than humans, using a specific reaching task. The abstract omits sample sizes, exact effect sizes, and statistical variance.
