Recall that zajonc and his colleagues (1969) employed the lowly cockroach in their studies of social facilitation. in the presence of other cockroaches, roaches would run faster down a straightaway to escape a bright light than they would alone, but took longer in the presence of a cockroach audience when the escape route was more complicated (i. e., when they had to run a maze). these findings support the idea that

The presence of other members of a species elicits the most dominant response.

Explanation:

These experiments were made because Robert Zajonc wanted to demonstrate that the social facilitation is a really important factor in our lives and he proved that, if the experiment worked on cockroaches it would work on humans too.

Social facilitation is when the presence of others increases or decreases performance.
