3. Copyright © Houghton Mifflin Company. All rights reserved.18 | 3 Answer Choice a is correct. Zajonc suggested that the presence of other people increases a person’s general level of arousal. This increased arousal enhances the performance of dominant responses, behaviors that one knows best. The increased arousal, however, impairs the performance of novel responses, behaviors with which one is relatively unfamiliar. In this example, only Joe has any level of experience that would lead to his behavior being a dominant response and, consequently, the performance of the behavior being enhanced by the presence of others.
