Question

Quizplus · Accepted Answer

Zajonc's research with cockroaches demonstrated that the mere presence of others (either as co-actors or as an audience) can facilitate performance on simple tasks but hinder performance on complex tasks. This supports the mere presence theory, which suggests that the mere presence of others is sufficient to produce social facilitation effects, without needing to invoke the fear of evaluation or other more complex cognitive processes.
