The effects of feedback consistency and feedback favorability on self-perceived task competence and perceived feedback accuracy

The present study, employing a 2 × 2 true-experimental design and regression analyses assessed the main and interactive effects of feedback consistency (consistent vs inconsistent), and feedback favorability (acceptable vs superior), for feedback given at two time periods on measures of perceived feedback accuracy and self-perceived task competence. Among the study's findings were that (a) the perceived accuracy of feedback at the second period was a function of the favorability of feedback received at the first time period, (b) the self-perceived task competence levels of subjects were jointly determined by the favorability of feedback received at both time periods, and (c) the perceived accuracy of feedback was a function of its consistency. Organizational implications of the study's results are offered.     

Behavioral contrast and generalization across settings in the treatment of autistic children

Previous research on the generalization of treatment gains across settings has typically focused on the question of whether generalization occurs or does not occur. However, the experimental literature suggests another possibility: that behavioral contrast may occur in extra-therapy settings if the reinforcement procedures in the therapy setting are highly discriminable from those in other settings. Therefore, this investigation was designed to systematically assess whether: (1) a highly discriminable treatment procedure in one setting would produce a behavioral contrast effect in other unmanipulated settings; and (2) such contrast-like trends could be eliminated if initially different reinforcement procedures in two settings were subsequently made similar. The results for the eight autistic children who participated in this investigation showed that: (1) When very different reinforcement procedures (primary rewards or punishment in therapy settings, and no rewards or punishment in extra-therapy settings) were in effect, the children showed contrast-like behavior changes in the untreated extra-therapy settings; and (2) such trends in responding could be eliminated, resulting in generalization of treatment gains, if the reinforcement procedures were subsequently made relatively similar in the two settings, even if the procedures consisted essentially of noncontingent reinforcement.     

A multitrait-multimethod examination of affect structure: hedonic level and emotional intensity

Past research on the personality structure of affect suggests that hedonic level and emotional intensity are two separate major dimensions. The present study employed a multitrait-multimethod approach to verify this finding. Seventy-four University of Illinois students completed daily mood reports and self-report questionnaires, and their parents completed a questionnaire about them. Both hedonic level and intensity measures were used. The convergent validities (monotrait-multimethod correlations) were all significant and tended to be highest for emotional intensity. The multitrait-monomethod coefficients were nonsignificant, as were the correlations based on different measures of different traits. The data were interpreted as supporting the distinction between hedonic level and affect intensity, as well as supporting the validity of the measures.     

The effects of positive and negative feedback and reward on originality

Forty subjects participated in a remote associates verbal learning task. Subjects were assigned to reward or feedback and positive or negative conditions in a 2 × 2 factorial design. Subjects in the various groups performed at significantly different levels with the positive reward group producing the most remote associates, folllowed, respectively, by the negative feedback, negative reward, and positive feedback groups. It was suggested that rewarding remote assocites results in relatively flat associative gradients, wherein the subject has ready access to all associates. Conversely, punishing common associates produces emotionality which reduces the response probability of remote associates, thus producing a relatively steep associative gradient. Extrapolations to Mednick's theory of creativity were made, suggesting that creativity is under environmental control.     

Self-instructions: Effects of cognitive level and active rehearsal

This research examined the effects of a self-instruction intervention on the relationship between cognitive level and conceptual tempo. Preoperational and concrete operational children received the Matching Familiar Figures Test prior to and after serving in either a no training control group, a content only control group, or a self-instruction group. Children in the content only control group received the same set of self-guiding strategy statements as those in the self-instruction group but without overt rehearsal of the statements. Cognitive level and conceptual tempo were strongly related; preoperational children tended to be classified as impulsive, concrete operational chidlren, as reflective. Although cognitive level predicted overall performance, with concrete operational children being more successful and more reflective than preoperational children, the influence of training was similar for both groups. On posttest, children in the self-instruction groups made more correct responses and were more reflective than children in the other two training groups.     

The treatment of tension headache—II. EMG ‘normality’ and relaxation

A selected group of patients complaining of severe and chronic tension headache (without muscular abnormality) were given a short 3-week course of relaxation treatment. Half of the subjects received progressive relaxation instructions, while the other half received relaxation plus calming imagery. Both groups showed substantial improvements in pain behaviour and in pain experience. The improvements were synchronous and still present at the 6–8 week follow-up assessment. Although no significant differences were found between the groups, the addition of imagery appeared to produce larger improvements on a number of measures. These results were compared with those reported obtained in a previous biofeedback study and the implications of both the studies were discussed with respect to tension headache and its treatment.     

The treatment of tension headache—I. Muscular abnormality and biofeedback

The specificity and efficacy of a short EMG biofeedback treatment were assessed in a selected group of chronic tension-headache cases—those having significantly elevated levels of muscle tension. The effects of training patients to raise/maintain EMG levels were compared to those obtained from patients who were trained to lower tension levels. The results showed little evidence of increased self-control of the muscle despite successful EMG control during six bio-feedback sessions. A progressive and significant reduction in resting level was found only in the groups trained to reduce EMG levels. The treatment proved ineffectual in reducing headache. The implications of the dissociation of muscle tension and headache are discussed both with respect to current views of tension headaches and the role of biofeedback in their treatment.     

The perception of interleaved melodies

If the notes of two melodies whose pitch ranges do not overlap are interleaved in time so that successive tones come from the different melodies, the resulting sequence of tones is perceptually divided into groups that correspond to the two melodies. Such “melodic fission” demonstrates perceptual grouping based on pitch alone, and has been used extensively in music.Experiment I showed that the identification of interleaved pairs of familiar melodies is possible if their pitch ranges do not overlap, but difficult otherwise. A short-term recognition-memory paradigm (Expt II) showed that interleaving a “background” melody with an unfamiliar melody interferes with same-different judgments regardless of the separation of their pitch ranges, but that range separation attenuates the interference effect. When pitch ranges overlap, listeners can overcome the interference effect and recognize a familiar target melody if the target is prespecified, thereby permitting them to search actively for it (Expt III). But familiarity or prespecification of the interleaved background melody appears not to reduce its interfering effects on same-different judgments concerning unfamiliar target melodies (Expt IV).     

The effects of self-monitoring on the expressive display of masculinity-femininity

Do self-monitoring processes influence (1) the correspondence between assessed personality and expressive masculinity-femininity, and (2) the cross-channel consistency (face, body, voice) of expressive masculinity-femininity? To answer these questions, 36 male and 36 females completed the Bem Sex-Role Inventory (BSRI) and Snyder's Self-Monitoring Scale, and then were videotaped as teachers. Five groups of naive judges rated these stimulus subjects on expressive masculinity-femininity, basing their respective ratings on: video pictures and voices, just pictures, just faces, just bodies, or just voices. A sixth group of judges rated subjects on physical attractiveness. The results indicated that judged physical attractiveness was significantly correlated with judged masculinity-femininity, with men being judged more masculine and females more feminine the more attractive they were. BSRI femininity correlated strongly with judged masculinity-femininity, and BSRI masculinity, less so. Finally, self-monitoring did prove to moderate the correspondence between personality and expressive behavior, and the cross-channel consistency of masculinity-femininity cues: however, these moderating effects were different for males and females.     

Distance estimates of children as a function of acquisition and response activities

Second and sixth graders (8 and 12 years of age, respectively) experienced a large-scale environment either actively or passively followed by a distance estimation task requiring either active or passive activity. Second graders were most accurate in those conditions where acquisition and response activities were congruent. These children significantly overestimated distances in the passive acquisition-active response condition. Sixth graders were equally accurate across all four experimental conditions. Results are discussed in terms of the complex interaction between acquisition factors and task demands which influence interpretations about spatial representations.     

The aftermath of heresy: a response to Pendery et al.'s (1982) critique of "Individualized Behavior Therapy for Alcoholics"

A point-by-point response is presented to Pendery et al.'s (1982) critique of the study “Individualized Behavior Therapy for Alcoholics (IBTA)”. Two independent, external investigations have critically examined the original records from the IBTA study. The IBTA study compared two different techniques for treating poor-prognosis, chronic alcoholic state hospital patients. It was found that a broad-spectrum behavioral treatment oriented to controlled drinking was a more effective treatment than was the standard hospital treatment program based on conventional wisdom. The Pendery et al. critique gave the appearance of being a refutation by presenting findings for only one group of Ss in a comparative study. In this response, it is shown that the experimental and control Ss were justifiably classified as gamma alcoholics, that Ss were randomly assigned to groups, and that the two groups were comparable in terms of pretreatment characteristics. Moreover, as regards the originally reported 2-yr treatment outcome findings, it is shown that Pendery et al, reported no specific events which were not already documented in the original study records which formed the basis for publications about the IBTA study. Finally, even in terms of long-term outcomes, i.e. mortality rates 10–11 yr after treatment, the experimentally-treated group (20% mortality) continued to fare better than the traditionally-treated group (30% mortality). Ironically, rather than Pendery et al.'s report being a refutation of the original published accounts of the IBTA study, it is concluded that the data reported by Pendery el al. actually strengthen the validity of the original publications. The attack on the IBTA study can be meaningfully viewed as a reflection of the scientific revolution presently underway in the alcohol field. The central impetus for conceptual change in the alcohol field, however, derives less from controlled-drinking research than from the lack of empirical support for conventional wisdom. Ideas are changing because the traditional view no longer inspires progress.     

The development of elaborative propensity in adolescence

A series of three experiments was conducted to verify the hypothesis that age differences in paired-associate learning proficiency across adolescence stem from the development of increasing elaborative propensity. An auxiliary aim was to determine whether previous study-to-study discrepancies in the pertinent age functions should be attributed to corresponding variations in learning materials or in characteristics of the populations sampled. Taken together, the results of the experiments provided support for the hypothesis. They also indicated, however, that students in late adolescence vary markedly in elaborative propensity, to the point that a substantial proportion of them are hardly distinguishable from preadolescents.     

The influence of task variation and maintenance tasks on the learning and affect of autistic children

Analyses of autistic children's learning and affect have begun to consider the role of antecedent variables, including the manner with which tasks are sequenced within instructional sessions. Within the context of a simultaneous-treatments design, this experiment evaluated autistic children's affect and rate of task acquisition under three experimental conditions. The conditions were (1) a constant task condition in which only one acquisition task was presented per session; (2) a varied-acquisition-task condition, in which 10 acquisition tasks were randomly interspersed throughout each session; and (3) a varied-with-maintenance-task condition, which randomly interspersed 5 acquisition tasks and 5 which had been previously acquired. The results showed significantly more efficient learning under the varied-maintenance condition, with no consistent differences separating the other two conditions. In addition, observers' ratings of the children's affect showed that the most positive judgments were produced by the varied-maintenance condition. The varied-acquisition condition was next while the constant task condition always produced the least favorable ratings. These findings are discussed in relation to the literature on massed versus distributed practice, stimulus variation, and success-induced motivation. The implications for upgrading the treatment and education of handicapped children are also reviewed.
