Working Memory and Pressure

Dr. Sanjay Gupta and Soledad O Brien of CNN discuss Sian Beilocks research on intelligence and choking.

Participants with a lower working memory capacity received the same score regardless of pressure. Explain the working memory capacity trade-off under high pressure. Who performs better, people with high working memory or low working memory?
