Effects of a coactor's prediction on latencies to predict and indentify stimuli

On each of 300 trials E's confederate (C) verbalized which of two stimuli would occur; then S made a prediction. Following each presentation, S and C pulled a trigger to identify the stimulus. Two latencies were measured: the interval between C's and S's prediction (prediction time), and the interval between stimulus presentation and S's identification response (choice RT). Prediction times were significantly shorter when S's prediction agreed rather than disagreed with C's prediction, when S's preceding prediction was correct rather than incorrect, and when S was female rather than male. Choice RT was influenced by distributions of C's stimulus predictions and C's prediction outcomes in directions supporting an expectancy model.     

Individual differences in speed of phonemic analysis, visual analysis, and reading.

College student subjects (Ss) classified phrases as making sense or not according to sound in one condition, according to visual appearance in another, and in abasic task in which either strategy would yield right answers. Ss who were relatively fast in the visual condition were faster at the basic task than Ss who were relatively fast in the sound condition. Other results suggested that the former Ss used a visual strategy in the basic task while the latter used a phonemic strategy.     

Adaptation-level and theory of signal detection: an examination and integration of two judgment models for voluntary stimulus generalization

An examination of two judgement models, adaptation-level (AL) theory and the theory of signal detection (TSD), was made in terms of their ability to handle data from several voluntary generalization studies. Both models were found to be somewhat inadequate, though in different ways. AL theory was found to be unable to predict amount or slope of the generalization gradient, while TSD was seen to be unable to account for shifts in judgment due to context and frequency effects. A combined AL-TSD model was presented which combines the advantages of each model and offers a good account of both choice and latency data in voluntary generalization     

The use of modeling to increase independent behavior

Three experiments were conducted aimed at increasing independence via use of modeling procedures in, respectively, two samples of neurotic outpatients and a sample of psychiatric inpatients. Significant gains in independence emerged in all three investigations. Subsidiary findings are reported regarding the operation in clinical contexts of ‘modeling-enhancers’ of demonstrated effectiveness in laboratory settings.     

Self-versus drug-produced relaxation and the effects of instructional set in standardized systematic desensitization

Snake fearful college students underwent Standardized Systematic Desensitization (SSD) treatment in which they received instructions designed to induce cognitions of either self- or drug-produced relaxation. Half of the subjects in each of these conditions were also given high expectancy therapy instructions and low expectancy therapy instructions respectively. All four SSD groups showed significantly greater improvement than a no-treatment control group on both the behavior avoidance test (BAT) and the self-report measure of fear. No differences between self- and drug-attributions of relaxation were found on any measure. Subjects' high expectancy ratings were significantly correlated with improvement on self-report measures but not related to BAT performance.

美国残障人士自我决定研究及对我国的启示

自我决定能力被认为是残障学生课程和学习指导的核心组成要素之一,培养自我决定能力的发展是促进残障学生在毕业后获得更好发展的一种教学策略。相关研究美国已成体系而国内始露头角。本研究阅读美国残障人士自我决定相关文献并进行以下五个方面的分析:自我决定概念起源与发展、相关政策法规、理论模型、教学模型、教育教学实践。根据文献分析美国自我决定研究的发展趋势,并思考在我国促进残障人士自我决定能力发展的可能性与必要性,且提出四点建议。     

Consistency Orientation and Models of Social Behavior: Is It Not Time for West to Meet East

The study examined the cultural differences in inconsistency-reducing behaviors by testing the reactions of 110 Japanese and 169 American college students to the inconsistencies arising from a difference of opinion with a significant other on ego-involving issues. It was predicted that (1) the Japanese sample would show more inconsistency support than will an American sample; (2) The American sample will show more preference for active inconsistency-reducing responses than will the Japanese sample; (3) on the hypothesis that contemporary social psychology's models of humans is based upon the American stereotype of the "typical American," the first two predictions will be more strongly confirmed by comparing the American subjects' stereotype of the "typical American" than by comparing their own reported choices. The findings generally supported the first two predictions and strongly supported the third one.     

Hemispheric alpha asymmetries during an electromyographic biofeedback procedure for stuttering: A single-subject experimental design

A single-subject “double-reversal” experimental design was used to investigate the use of electromyographic (EMG) biofeedback on the dysfluent behaviors of a right-handed male stutterer. A systematic decrease in EMG amplitude accompanied a progressive approximation of increased verbal complexity resulting in increased fluent behavior. Electroencephalographic (EEG) alpha data (8–12 Hz) gathered during baseline and pre- and post- treatment sessions appeared to co-vary with changes in fluency with right hemispheric suppression associated with greater dysfluencies and left hemispheric alpha suppression with decreased dysfluencies. The results are discussed relative to stutterer's adoption of differing behavioral production strategies for fluent speech that are associated with hemispheric information processing strategies.
