Choking and excelling under pressure in experienced classifiers.
We extend previous work examining the effects of pressure on category learning to the effects of pressure on categorization performance in highly trained individuals. After extensive training on either a rule-based or an information-integration classification task, half of the participants performed the same task on a fifth day while under pressure to earn a monetary bonus ($50) for themselves and a partner. Performance of this group was compared with that of a low-pressure control group who performed without the pressure manipulation. Pressure caused performance decrements both for experienced classifiers performing rule-based tasks and for those performing information-integration tasks, as compared with control groups. These results contrast with those of previous research, where inexperienced classifiers choked on rule-based tasks but excelled on information-integration tasks. An additional "superpressure" block of trials was given at the end of the fifth session. Under this type of pressure, participants performing an information-integration task outperformed those performing rule-based tasks. Implications for theories of choking under pressure are discussed.
