Subject Competence and Minimization of the Bystander Effect

While performing a drawing task, either alone or in the presence of an observer, high- and low-competent subjects heard a workman fall off a ladder in an adjoining room. As expected, high-competent subjects (Registered Nurses) who witnessed the emergency with another bystander helped as frequently as subjects who witnessed the emergency alone; low-competent subjects (general students) evidenced the familiar bystander effect. Responses to the post-emergency questionnaire indicated that at the time of the emergency both high- and low-competent subjects felt strongly that they should do something to help the workman. The minimization of the bystander effect for the high-competent subjects was mediated by confidence in their ability to help the workman and in knowing what steps to take to help. Discussion focused on the role of subject competency in bystander intervention, effective debriefing, and the subjects' positive reactions to participating in a bystander experiment.     

Motivating and reinforcing functions of the male sex role: Social analogues of partial reinforcement,delay of reinforcement,and intermittent shock

After listening to a masculine male, female subjects learned an instrumental escape response reinforced by the opportunity to listen to an androgynous male. The results of three experiments revealed a striking correspondence between conventional learning variables and social analogues of acquisition, partial reinforcement, delay of reinforcement, and intermittent shock. Subject responses to a postconversation questionnaire indicated that the comments made by the androgynous male were judged as more appropriate and more honest, and he was rated as more likable, more intelligent, more moral, and more mentally healthy, than his masculine counterpart. Discussion focused on the importance of investigating male sex role action using additional theoretically relevant social analogues of conventional learning variables and other familiar learning paradigms.
