Which finding is NOT consistent with a cognitive explanation of social facilitation?

A) Many species,including cockroaches,show signs of social facilitation.
B) Recall is poorer when stimuli are presented in the presence of others.
C) Facilitation is reduced if the others in the situation are not noticed.
D) Presence of others improves performance on the Stroop task.

Cognitive explanations of social facilitation focus on the effects of the presence of others on mental processes such as attention, perception, and memory. The fact that many species, including cockroaches, show signs of social facilitation suggests that the phenomenon may not be entirely based on cognitive processes, but rather on more basic or instinctual responses to social presence. This is not consistent with a purely cognitive explanation, which would emphasize the role of mental processes in the presence of others.
