Perceived depth vs. structural relevance in the object-superiority effect

When subjects must identify a barely visible line in a briefly flashed display, their accuracy depends on the configuration of the context in which the target line appears. Weisstein and Harris (1974) found that accuracy is highest when the target is part of a pattern that resembles a unified, three-dimensional object, and lowest in a flat-looking pattern composed of disconnected lines; they labeled this phenomenon the object-superiority effect. In the three experiments reported here, identification accuracy was found to correlate highly and significantly (r =.78) with the judged depth of the patterns. Judged structural relevance of the target line to the pattern (McClelland & Miller, 1979) was uncorrelated with accuracy (r=?.28). Even when the target line appeared as an isolated fragment within the context pattern, a pattern perceived as three-dimensional yielded higher identification accuracy than one perceived as flat.     

Belief and Values in the Nuclear Debate1

A questionnaire was administered to 47 participants attending a workshop on nuclear energy shortly after publication of a report on a proposed nuclear fuel reprocessing plant. Supporters and opponents of the proposed development differed markedly in their estimates of its possible consequences, and of the relative importance of these consequences. They also differed in their endorsement of pro- and anti-nuclear lobbies, and the factors which they felt contributed most to the “quality of life”. Overall, pro-nuclear subjects appear to place emphasis on the economic benefits of nuclear energy, while anti-nuclear subjects appearad more concerned with social and political risks, and regraded alternative energy sources as more viable. It is concluded that an analysis of such attitudinal differences requires a consideration not only of differences in beliefs, but also of differences in belief salience.     

Emotional Empathy in a Courtroom Simulation: A Person-Situation Interaction1

A pair of experiments were conducted using a simulated courtroom trial of a criminal case. In Experiment I subject-jurors were asked by defense counsel either to imagine themselves as the defendant (empathy-inducing appeal) or to pay close attention to evidence (nonempathy appeal). Later the judge delivered only general instructions or, in addition, charged jurors to give consideration only to the facts presented. When there was no Fact-focused judge's charge, juror-subjects who heard the empathy-inducing appeal rated the defendant's actions as more lawful and attributed less of the cause for the incident to his personality than did their counterparts in the nonempathy condition. Experiment II included individual differences in the tendency to empathize as an additional mediating variable. The original pattern of effects found for the manipulated variables in Experiment I appeared again, but were overshadowed by the stronger effects of the individual difference variable and of subject sex. Subject-jurors who scored high on the empathy individual difference measure rated the defendant less guilty, assigned less cause to him, and showed corresponding mood shifts when they heard the empathy-inducing appeal. In addition, male subjects empathized more strongly with the male defendant and viewed him more favorably.     

Attitudinal effects of the use of evaluatively biased language

In an experiment to study the effects on attitudes of requiring subjects to use evaluatively biased language, 84 schoolchildren aged 13–14 years completed a questionnaire to measure their attitudes on the issue of adult authority over teenagers, before and after writing an essay on this issue in which they were either required to incorporate words from a list all of which implied a positive evaluation of a pro-authority position or a negative evaluation of an anti-authority position (pro-bias condition), or required to incorporate words where the implied evaluations were reversed (anti-bias condition), or were given no words to incorporate (control condition). Relative to controls, pro-bias subjects showed as a shift towards a more pro position and anti-bias subjects became more anti irrespective of their initial attitudes (pro-bias versus anti-bias comparison, p<.01). However, when tested 6 days later most of this effect had disappeared, particularly in the case of subjects whose initial attitudes were least pro. At this final session, subjects also rated attitude statements on the issue in terms of scales constructed from the pro-bias and anti-bias word lists. In accordance with previous research, the more pro subjects' attitudes, the more they showed greater polarization of judgement on the pro-bias than the anti-bias scales (p<.000l). It is concluded that a person's attitude may be related to the kind of evaluative language he will apply to an issue, and that when a person is induced to use language implying a particular evaluation of an issue, he may change his attitude, at least in the short term, so as to be more congruent with the language he has used.     

The effects of self-selection on trainees' verbal helping skills performance

Self-selected paraprofessional trainees enrolled in a helping skills training program participated in a 6-minute pretraining helping interview from which their frequency of continuing responses was obtained. Continuing responses allow helpees to present their concerns in a nonthreatening, supportive environment and are important in the relationship establishing stage of the helping process. For data analysis purposes only, trainees were divided into three groups, a high, medium, and low group, based on the frequency of continuing responses made. Following training, at posttest, no significant differences were found among the three groups on the amount of continuing responses made during a second identical 6-minute interview. Implications for various selection procedures and training are discussed.     

Youth Counselor Burnout

Counselors of unruly, runaway, truant, or delinquent children and their families run the risk of emotional overexposure– “burnout” as a result of intense client needs and problems. Survival on the job requires taking steps to avoid internalizing caseload pressures. These steps include: helping-not replacing-parents, keeping meetings brief, responding to emergencies selectively, taking simple steps first, using humor, taking care of oneself, expecting complications, avoiding panic, and knowing when to withdraw.     

RELATIVE EFFECTIVENESS OF TEACHER ATTENTION AND THE “GOOD BEHAVIOR GAME” IN MODIFYING DISRUPTIVE CLASSROOM BEHAVIOR1

A variety of behavioral procedures have been employed in recent years to modify disruptive classroom behavior. Such methods have been developed with the belief that curtailing disruptive behavior would strengthen positive classroom performance. In this study, two procedures, the good behavior game and the teacher-attention method, were compared to determine short-run effectiveness. Four teachers (two fourth-grade and two fifth-grade) implemented both methods in their classrooms over a five-week period. Presentation of methods was alternated in a counterbalanced design to control for order effects. Each of the four classrooms consisted of 25 students. A time-sampling procedure was used to record the presence or absence of disruptive behavior within 15-second intervals. Disruptive behavior was defined as any talking-out or out-of-seat behavior without permission. The results indicated that both procedures were effective in modifying disruptive classroom behavior, but that the good behavior game reduced disruptive behavior significantly better than the teacher-attention method. In addition, all teachers preferred the game to the teacher-attention procedure. This reaction seemed related to the effort involved in initiating the two activities. The good behavior game required less effort on the teacher's part. However, use of the game alone raises certain ethical considerations. One such issue involves abuse of peer pressure. Also, there is a possibility that negative rules may tend to promote resentment. Positively stated rules would ameliorate that problem. Another relates to the possibility that some teachers might be carried away by the ease of the game's implementation to the extent that behavior control becomes the primary objective in the classroom. As a result, one might consider use of the game to maximize short-term change, but then phase out this procedure in favor of another method (e.g., teacher attention) for long-run effects.     

Perception of voicing and place features in whispered speech: A dichotic choice analysis

To offset shortcomings of existing demonstrations of right-ear superiority in the analysis of formant transitions, an experiment was performed on whispered speech. Two aspects of dichotic listening performance were examined in a single-report paradigm: the right-ear advantage (REA) for the perception of the voicing distinction and the feature sharing advantage (FSA) for both voicing and place features. A significant REA was obtained for the voicing distinction cued by first formant transition in the absence of a switch from aperiodic to periodic excitation. This, plus a greater incidence of voiced responses to right-ear stimuli, suggests that a distinction involving transitions can specifically augment the REA. The data also showed better identification of place and of voicing feature values when the competing dichotic speech stimuli shared these respective features (FSA) than when they did not. This FSA was restricted to the feature shared and hence not an effect of response uncertainty. The implications of these results for models of speech processing are discussed.
