Estrangement,epochē, and performance: Bertolt Brecht’s Verfremdungseffekt and a phenomenology of spectatorship

Social discounting of pain

Impatience can be formalized as a delay discount rate, describing how the subjective value of reward decreases as it is delayed. By analogy, selfishness can be formalized as a social discount rate, representing how the subjective value of rewarding another person decreases with increasing social distance. Delay and social discount rates for reward are correlated across individuals. However no previous work has examined whether this relationship also holds for aversive outcomes. Neither has previous work described a functional form for social discounting of pain in humans. This is a pertinent question, since preferences over aversive outcomes formally diverge from those for reward. We addressed this issue in an experiment in which healthy adult participants (N = 67) chose the timing and intensity of hypothetical pain for themselves and others. In keeping with previous studies, participants showed a strong preference for immediate over delayed pain. Participants showed greater concern for pain in close others than for their own pain, though this hyperaltruism was steeply discounted with increasing social distance. Impatience for pain and social discounting of pain were weakly correlated across individuals. Our results extend a link between impatience and selfishness to the aversive domain.     

Seeing how it’s done: matching conditions for observer rats (Rattus norvegicus) in the bidirectional control

In an attempt to increase the reliability of the demonstrator-consistent responding effect produced in the bidirectional control procedure, experiments 1–4 sought conditions that would magnify the matching effect. The aim was to produce a robust demonstrator-consistent responding effect in order that future analytic experiments could investigate the psychological processes responsible for this effect. The joystick responses of observer rats trained using the standard bidirectional control procedure parameters were compared with those of observers subject to conditions identified in the social learning literature as favourable for imitation. Unlike mice, observer rats in experiments 1 a and 1 b tended to push a joystick in the same direction as their demonstrators when the demonstrators were either familiar or unfamiliar males and females. Comparable demonstrator-consistent responding occurred following observation of a standard and a salient joystick response (experiment 2). Experiment 3 showed that the discriminative accuracy of a demonstrator’s responding was important for matching behaviour, and suggested that matching might be enhanced with more than the conventional single observation session. Experiment 4 confirmed that the bidirectional control effect is sensitive to the amount of observational experience; after six observation sessions, demonstrator-inconsistent responding occurs. The results of experiments 1–3 are, and those of experiment 4 are not, compatible with the hypothesis that demonstrator-consistent responding in the bidirectional control is caused by olfactory cues deposited by demonstrators on the joystick.

Negative transfer errors in sequential cognitive skills: strong-but-wrong sequence application

Three experiments investigated the role of processing sequence knowledge in negative transfer within multistep cognitive skills. In Experiments 1 and 2, more training resulted in higher error rates when new processing sequences that resembled familiar ones were introduced in transfer. Transfer error responses were executed with the same speed as correct responses to familiar sequence trials, and the errors appeared to be undetected by the performers. Experiment 3 tested whether the effects of sequence learning were attributable to explicit or implicit knowledge of processing sequences. Evidence favored the implicit learning interpretation. Findings are discussed in relationship to earlier demonstrations of the einstellung effect and to current taxonomic theories of human error.     

Classical conditioning of pupillary constriction

Previous attempts to condition classically the pupillary response have resulted in mixed outcome. Studies using light as the UCS have generally been unsuccessful while those studies using shock as the UCS have been more successful. In the present study six subjects were visually presented 15 CVC trigrams while their pupil sizes were monitored. Five of the CVCs had been previously presented, five had been previously presented while paired with shock, and five had not been previously presented. Analysis indicated that more pupillary constriction occurred to the five CVCs paired with shock than those presented without shock or those not previously presented. The resulting classically conditioned pupillary constriction is discussed in terms of the development of meaning through classical conditioning.     

Effects of maternal employment on sex role orientation of adolescents

Sex role orientation was determined for 352 high school seniors in Plano, Texas. Using maternal employment status as the independent variable, students were divided into groups according to full-time employed mothers or full-time homemaker mothers. Results of the three-part instrument indicated that adolescents of employed mothers had a more liberal sex role orientation and attitude toward division of household tasks than adolescents of homemaker mothers. Mean scores from two sections of the instrument indicated nontraditional attitudes. Results indicated that maternal happiness with employment did not affect male and female sex role orientation.     

Factors Predisposing Women to Take Precautions Against Breast and Cervix Cancer

The utility of the Theory of Reasoned Action (TRA), the Health Belief Model (HBM), and the Subjective Probability Model (SPM) in a health education diagnosis to discover predisposing factors for performing breast self-examination (BSE) and having a Pap test was explored in a survey of 123 women. Each model was a significant predictor of BSE and Pap test intentions. However, a composite model comprising the TRA's attitudinal and normative components supplemented by the barriers component of the HBM was the most useful in performing a health education diagnosis in relation to breast self-examination and the Pap test. "Psychological relevance" scores of particular beliefs obtained by SPM procedures tended to confirm the TRA's correlational method of identifying primary beliefs that would be the targets of persuasion to change BSE and Pap test intentions.     

Physiological arousal of obese persons to food stimuli

Physiological arousal was measured in 20 obese and 20 normal-weight subjects during presentation of imagery tasks with food- and nonfood-related stimuli and during presentation and eating of food. No differential arousal, as measured by skin conductance, was obtained between the groups for any of the stimuli. Presentation and eating of the food did produce significant arousal in subjects.     

The effects of methylphenidate on levels of processing and laterality in children with attention deficit disorder

Effects of stimulant medication (methylphenidate) on levels (feature, name, semantic) of word processing by the left and right hemisphere were assessed in 31 attention- deficit- disordered children. In a double-blind procedure, same- different decisions were made to tachistoscopically presented word pairs under medication and placebo. Analysis of manual response times failed to show any negative effects of medication. Feature decisions were faster than name decisions, which were faster than semantic decisions. Methylphenidate induced a right visual field advantage (left hemisphere) for the name decision, which was interpreted as a normalization effect. The results suggest that (1) methylphenidate may selectively improve the phonological level of word processing and (2) methylphenidate's favorable therapeutic effect is produced through inhibition of excessive right hemisphere activity in response to task demands that engage the left hemisphere.This research is based in part upon a doctoral thesis completed by the first author in the Department of Education, University of Toronto.
