Form of evaluation and audience expertness as joint determinants of audience effects

A more stringent test was made of Martens and Landers' (1972) conclusion that direct evaluation of performance and outcomes leads to greater performance impairment than indirect evaluation of outcomes only. Expert and nonexpert audiences viewed Subjects performing a motor task with visual information and knowledge of outcomes (direct evaluation), with no visual information but knowledge of outcomes (indirect evaluation), and the absence of both visual information and knowledge of outcomes (no evaluation). Contrary to Martens and Landers, with an expert audience, both direct and indirect evaluation impaired performance equally. Results indicated that at least two factors in social facilitation research, audience characteristics and form of evaluation, can be considered interactive determinants of evaluation potential. These results directly support Cottrell's (1968) notion that the potential for evaluation characterizing a social situation is the chief source of audience and coaction effects in humans.     

The effect of vicarious punishment on prosocial behavior in children

Two experiments are reported dealing with the effects of vicarious punishment on prosocial behavior. In Experiment I, first and second grade females who witnessed a peer model being punished for a refusal to share (“nonsharing, punished”), shared more than an appropriate control group. Sharing was similarly heightened, however, in a group who witnessed punishment to the model which was not contingent upon any specific behavior (“punishment only”). Experiment II tested and confirmed the hypothesis derived from Experiment I that noncontingent vicarious punishment has a generalized inhibitory effect on antisocial behaviors. First, second, and third grade females were shown either the “nonsharing, punished,” “punishment only,” or baseline videotapes used in Experiment I. Subsequent to viewing the tapes, subjects in the “punishment only” condition helped the experimenter significantly more than did subjects in the “nonsharing, punished” and baseline conditions. The ability of existing theoretical treatments of vicarious punishment to account for these results is questioned.     

Effects of felt adequacy and opportunity to reciprocate on help seeking

This experiment was prompted by the belief that felt inadequacy and lack of opportunity to reciprocate act as deterrents to help seeking when help is needed. The experiment was conducted on 56 freshmen by modifying Greenberg and Shapiro's physical disability paradigm. Subjects were told that they could not meet the quota on a manual task but had done well (poorly) for persons similarly handicapped (by arm in sling). Later they learned that the electricity would be shut off in 2 hr (15 min), making it possible (impossible) to help the visually handicapped fellow worker later on a visual task. The hypothesis that felt inadequacy inhibits help seeking was fully supported, while the corresponding hypothesis regarding lack of opportunity to reciprocate received only partial support. There were no sex differences. The relevance of these data for embarrassment theory is discussed.     

Collective coping with stress: group reactions to fear, anxiety, and ambiguity.

A review of studies examining the fear-affiliation relationship revealed that none had ever observed groups in interaction while awaiting a fearful event. It was predicted that such groups would, consistent with individual member's previously studied affiliative preferences, spend more time interacting in the service of social comparison needs than would groups facing anxiety or ambiguity. This prediction was strongly supported, and in addition, it was found, as expected, that groups in the fear condition developed a relatively high degree of cohesiveness as measured by intragroup attraction ratings. The implication of these results for the interpretation of the functional relationship between stress and cohesiveness was discussed.     

Behavioural contrast and autoshaping

This experiment was designed to investigate the importance of autoshaping to a signal for reinforcement in the production of behavioural contrast. Two groups of pigeons were given discrimination training on a mult VI-EXT schedule: the stimuli present in the two schedule components shared common attributes, but were distinguished by the presence or absence of a visual feature. For one group (the feature positive group) the feature signalled the availability of reinforcement. For the other group (the feature negative group) the feature signalled nonrein-forcement, and for this group there was no stimulus element which unambiguously signalled reinforcement. The feature positive group showed a higher response rate during the VI component of the mult VI-EXT schedule than the feature negative group. This finding was interpreted as support for the autoshaping explanation of behavioural contrast. The results differed from those of Jenkins and Sainsbury (1969, 1970) in that both the feature positive and the feature negative groups showed discrimination learning.     

Persistent behaviour in extinction after partial deprivation in training

Four groups of rats were trained to run an alleyway with one trial per day. Two groups were always deprived when trained while the other two received a partial deprivation schedule. One group of each pair received a continuous reward in the goal box while the other received partial reward. A partial reinforcement effect was found during extinction. The partially deprived groups also showed persistence in extinction. This result extends parallels between the effects of satiation and nonreward upon behaviour.
