Gaertner and Dovidio (1977) Used the Bystander Apathy Paradigm to Unearth

Gaertner and Dovidio (1977) used the bystander apathy paradigm to unearth prejudice. In an emergency situation, they found that when there were potential helpers:

A) neither black nor white participants aided the victim.
B) the rate of bystander apathy was no different to when there were no helpers.
C) black participants did not use the cue of the victim's race, but white participants did.
D) bystander apathy increased when the victim was black rather than white.
