Recall that Robert Zajonc placed cockroaches in either a complex maze or a simple maze. He created three other conditions as well. Any given cockroach was induced to navigate the maze (a) entirely alone; (b) in the presence of an "audience" of cockroaches; or (c) simultaneously with another cockroach (but without an audience) . The audience condition (b) permitted Zajonc to demonstrate whether

A) audiences pay attention to competitors.
B) the mere presence of others can facilitate or hinder performance.
