Darley and Latané (1968) recorded the speed with which subjects summoned help for a person in trouble. Subjects thought either that they were the only one listening to the person (Group 1, n 5 13), that one other person was listening (Group 2, n 5 26), or that four other people were listening (Group 3, n 5 13). The dependent variable was the speed with which the person summoned help (5 1/time 3 100). The mean speed scores for the three groups were 0.87, 0.72, and 0.51, respectively. The was 0.053.
