One exception in this line of research is the finding that for highly creative individuals, a moderate noise level may lead to higher creative performance relative to both low and high noise levels (Toplyn and Maguire 1991 ). Toplyn and Maguire had participants complete a number of creativity tasks and used their performance on one such task (the RAT) to assess their baseline creativity level. They found that highly creative individuals (defined as those who scored high on the RAT) exhibited greater creativity on other tasks when presented with a moderate level of white noise than when the noise level was either high or low. Toplyn and Maguire speculate that arousal may underlie this effect. For less creative individuals, on the other hand, no significant difference was observed among low, moderate, and high levels of noise.
