Question 2

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
  a. members of even the lowliest species experience evaluation apprehension.
  b. cockroaches differ from humans in their response to other members of their species.
  c. the presence of other members of a species elicits the most dominant response.
