Robert 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 straight-away 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
A) the presence of other members of a species improves performance on a well-learned response.
B) cockroaches differ from humans in their response to other members of their species.
C) the presence of other members of a species impedes performance on a well-learned response.
D) cockroaches respond better than humans in the presence of other members of their species.
E) members of even the most lowly species experience evaluation apprehension.
