Awareness of the response after feedback training for changes in heart rate and sudomotor laterality

What is the relation between the ability to control visceral responding on a biofeedback task and the ability to report behaviors actually contributing to this performance? Subjects received biofeedback training for unidentified visceral responses and then gave written reports about what they had done to control the feedback displays. Independent judges were given these reports and, on the basis of knowledge about activities known to contribute to visceral activity, were asked to determine the visceral responses for which the subjects had been trained. The reports of subjects who succeeded at bidirectional control of heart rate (Experiment 1) or sudomotor laterality (Experiment 2) showed awareness of behaviors related to feedback as assessed by this procedure, whereas the reports of subjects who failed at bidirectional control did not. Subsequent experiments indicated that these results did not depend on a learning strategy that might have been specific to the initial studies. These findings call into question the view that people are unaware of what they have done to produce the response after training on biofeedback tasks. Earlier studies reporting lack of awareness in biofeedback are discussed in light of factors that affect the measurement of biofeedback learning and response awareness.     

Determinants of emotion attributions: A unifying view

Two cognitive approaches, introduced by Schachter and Singer (1962) and by Valins (1966), have dominated the experimental study of emotion attributions. However, subsequent results using these approaches have not appeared to be very consistent, and this view is not consistent with more physiologically oriented theory. Research significant in the development of theory from these approaches was examined. Inconsistent findings using the Schachter and Singer paradigm were attributed to the difficulty of producting completely ambiguous physiological cues. The existence of active search in determining the cause of arousal was established and found central to production of Valins's false feedback effect. Postulated mediation by self-persuasion was found to provide the best fit to the existing data. The generality of these studies was described in terms of a more comprehensive theory based on the finding that the relative ambiguity of situational and physiological cues seems to provide the fundamental control over the emotion attribution process. This synthesis eliminates the deficiencies in previous hypotheses by more completely encompassing potential cue combinations.     

Uncontrollable shock proactively increases sensitivity to response-reinforcer independence in rats

Learned helplessness theory predicts that animals exposed to inescapable shock acquire an expectancy of response-reinforcer independence, which proactively interferes with learning of response-reinforcer dependence. The theory also predicts that this expectancy can increase sensitivity to subsequent instances of response-reinforcer independence. These experiments test the latter prediction in a paradigm that minimizes the confounding effects of shock-induced activity deficits. Rats were trained to respond for food, then given either escapable, inescapable, or no shock. Subsequently, they received two sessions of response-contingent food followed by sessions of noncontingent food deliveries. During this phase, inescapably shocked animals decreased responding faster than did controls. Experiment 2 replicated this finding with a different schedule of food delivery and a procedure that more directly minimized the possibility that the outcome is due to either direct or indirect shock-induced activity changes. These results support the prediction that uncontrollable aversive events can increase an animal's sensitivity to noncontingent response-reinforcer relationships.     

Teachers do not Deal in Widgets

Although the use of merit pay, incentive pay, bonus pay, and job promotion are well-established measures in the private or corporate sector of American society, few examples of successful teacher merit pay systems exist. In 1983, the Eastern Washington University Department of Education surveyed six major private corporations to determine whether corporate merit pay programs could be applied to teachers and educational institutions. Survey findings suggest several reasons why merit pay programs for teachers will probably fail: (a) lack of monetary goals; (b) the necessity for subjective evaluation, which requires multiple measurement devices, extensive supervision, and time; (c) the absence of a many-tiered corporate structure in most educational institutions; and (d) increased supervisory direction that could stifle creativity and flexibility.
