We examined the influence of the sex of the subject reacting to the rape victim, the type of rape (stranger vs. acquaintance), the location of the rape (inside vs. outside the victim's home), and the victim's attribution concerning the cause of the rape, on undergraduates' reactions to a rape victim. American undergraduates (264 women, 230 men) read a Rape Crisis Center Intake Form, watched a videotape of a rape victim (an actress) describing her psychological and behavioral reactions to the rape, and completed three questionnaires assessing their reactions to the victim. Women were more supportive of the rape victim than were men, and the stranger rape evoked more chance and characterological attributions than did the acquaintance rape. A rape outside the home evoked more chance attributions than did an "inside" rape. The rape victim was rated as having been more traumatized by the experience if she made any causal attribution than if she made no attribution at all.
