Levine and Others (2005) Conducted an Experiment in Which a "Jogger

Levine and others (2005) conducted an experiment in which a "jogger," a confederate, was wearing a t-shirt that was either the same as the participant's favorite soccer team, the t-shirt of a rival team, or a neutral t-shirt. The "jogger" fell in front of the participant, appearing to sustain an injury. Participants were

A) less likely to help if the jogger was wearing a rival team shirt.
B) more likely to help if the jogger was wearing their own favorite team's shirt.
C) both less likely to help a jogger wearing a rival shirt and more likely to help a jogger wearing their own team's shirt.
D) equally likely to help in the "favorite" and "neutral" conditions, but more likely to help in the "rival" condition.
