Performance under pressure

Imagine your brain is a coach drawing a play on a whiteboard for your muscles. For a normal task, the coach draws a clear, simple diagram, and your muscles know exactly what to do. But when a massive, 'championship-level' prize is on the line, the coach gets so excited about the reward that they start scribbling frantically all over the board. The play becomes a messy, confusing jumble. This study found that something similar happens in the motor cortex—the brain's 'whiteboard.' The overwhelming signal of a 'jackpot' reward creates so much neural noise that the specific plan for a movement gets lost, leading to a clumsy error or 'choking.'
