Using a self-evaluation system as a group contingency

The efficacy of a group-evaluation system was examined, with a reversal design, in two classes of students with disabilities. The results suggested that a group-evaluation system was effective in decreasing the inappropriate verbalizations of both groups. Student satisfaction data revealed that the students in both groups had positive reactions to the system. Factors contributing to the success of the intervention as well as suggestions for its implementation are discussed.     

The effects of hemispheric differences on feature perturbations

Summary Hemispheric differences for feature perturbations were investigated in two experiments. Stimulus displays consisting of five small squares arranged in a single row were presented tachistoscopically, with the subject instructed to state in which square a horizontal tick mark was located. Ticks could occur in any of the three middle squares, with half of the ticks presented on the inside and half presented on the outside of the square in relation to the fovea. Experiment 1 presented each array of five squares to the right or left of fixation at one of three distances from the fovea. Experiment 2 manipulated the distance between the squares and kept foveal distance constant. In each experiment, fewer errors were made when stimuli were presented to the left visual field/right hemisphere than when they were presented to the right visual field/left hemisphere, when ticks migrated toward the fovea. Experiment 1 found that increasing the distance from the fovea increased the error rate, but did not change the hemispheric differences. Experiment 2 found that increasing the distance between the squares did not change hemispheric effects reliably. The data imply that hemispheric differences for perceptual processing begin very early during sensory analysis.     

Counseling in heart surgery

Conclusion In conclusion, a word about the spiritual aspects of the ministry to the heart patient. All members of the hospital bly, the family coming to the hospital team minister in one way or another. The chaplain has a unique place on this team. He, too, can escape from a ministry by use of religious injections. There are times for prayer and sacraments, and only the individual chaplain can finally decide the appropriate if, where, and when.As the chaplain explores the meaning of the hospital experience with the patient—the patient's feelings about life, death, experiences, and goals; giving and understanding where it is needed; aiding in the healing of the whole person—surely this ministry is a reflection of his motivation and is in part an attempt to realize in another the wholeness and fullness of man. It is not the physical therapy of the doctor; it is not the psychotherapy of the psychiatrist. It is the spiritual therapy of the chaplain.     

Predicting diagnosis performance with measures of cognitive style

This study examines the relationship between performance on a context-independent fault diagnosis task and two dimensions of cognitive style: field dependence/independence (D-I) and focusing/scanning (F-S). The effects on diagnosis performance of training and the ability of both dimensions of style jointly to predict fault-finding ability were considered. The results showed that field independents and focusers were superior fault diagnosticians. Training, in the form of verbal feedback messages, was uniformly effective for the D-I dimension although field independents maintained a superior level of performance, over field dependents. In general, for the F-S dimension, training had little effect on either the focusers or scanners. A combination of scores on the F-S and D-I dimensions significantly enhanced the proportion of the variance in testing efficiency that could be accounted for during fault-finding. Finally it is argued that the F-S and D-I dimensions should be recognized as measures of ability, not style. Future research should be directed at identifying between subject differences on fault diagnosis tasks with reference to theories of information processing.     

An individual differences pure extinction process

A pure extinction process memory retrieval latency model is completely characterized by the number of items to be recalled n and the recall rate λ. In this paper λ is allowed to vary across the population of subjects. Results are given for arbitrary individual differences distributions on λ. When λ is distributed gamma the results are very simple and method of moment estimators are easily obtained. In addition the shape parameter of the gamma individual differences distribution turns out to be an index of the degree of heterogeneity of the recall parameter. The pure extinction process model is also appropriate for certain collection and detection tasks.
