An evaluation was made of reality orientation therapy utilizing 14 male patients with dementias of various types. The therapy is designed to improve memory and reduce confusion in elderly and demented individuals. Utilizing a group comparison with crossover design, it was found that the patients improved significantly over sessions on orientation items actually taught during those sessions. However, no significant improvement was found on a series of generalization items consisting of orientation-related questions that were not asked during sessions. Furthermore, there was no generalization to ward activities. It was noted that individual responses to the treatment were quite varied, and so three cases reflecting highly different responses are presented.Indebtedness is expressed to the Veterans Administration for support of this research. 相似文献

The purpose of the study was to compare the accuracies obtained from whole interval, partial interval, and momentary time-sample recording procedures. Two types of accuracies were defined. Between-methods accuracy is the degree to which an observer using a particular recording method agrees with a standard using a continuous recording method. Within-methods accuracy is the degree to which an observer and a standard agree when both use the same recording method. Fifty-four undergraduate students viewed a videotape of a woman twisting her hair and recorded the occurrence or nonoccurrence of the behavior using one of the three recording methods. Tapes were divided into segments with low, intermediate, and high rates of behavior. Partial and whole interval recording obtained poorer between-methods accuracies than momentary time sampling. Results showed that whole interval and momentary time-sampling procedures yielded higher within-method accuracies than partial interval recording. Thus, momentary time-sampling recording provided the advantages of both greater representativeness and as few or fewer observer errors than whole or partial interval recording procedures. Use of the interval recording methods by researchers must be justifiable within this framework. 相似文献

Phonemic restoration is an illusion in which listeners hear spoken words as intact, even though parts of them have been replaced by an extraneous sound. An improved methodology was used to investigate how much the illusion depends upon the bottom-up confirmation of expectations generated at higher levels. A powerful bottom-up factor was phone class of the sound to be restored, and its acoustic similarity to the sound that replaced it. When white noise was the replacement sound, fricatives were better restored than vowels, whereas the pattern reversed with a pure tone replacement. Including a short silence period increased restoration of stop consonants. The data indicate that phonemic restoration depends upon the interplay between the listener's expectations and the acoustic signal. 相似文献

Three chronic and severe obsessive-compulsive neurotics were treated with behavioral intervention strategies and psychotropic medication. The effects of treatment were evaluated in three separate experiments with single case experimental designs. The results suggest that response prevention was effective in reducing ritualistic behavior while the effects of flooding and antidepressant medication added little to outcome. The results also suggest that strategies aimed only at reducing compulsive behavior per se are insufficient in eliminating other associated difficulties (e.g., depressive symptoms, interpersonal problems) and that a comprehensive approach to treatment is needed. 相似文献

A model for the measurement of the discrepancy between two scores is presented and discussed as a paradigm for the study of growth or experimentally produced change. The model assumes two tests or measures differing in complexity, and it analyzes the true difference between the test scores into a component that is entirely dependent on the first or base-line test and a second component that is entirely independent of it. Equations for estimating both components are given and these are compared with other measurement efforts with similar goals. 相似文献

Three groups of entering college freshmen, possessing varying degrees of identification of educational-vocational goals, were compared on a variety of personality, achievement, aptitude, school, and family factors. The major differences indicated that the most undecided group was more dependent than the other two groups, but equal to the most decided group in academic achievement, while a middle, or tentatively decided group, was not as successful academically as the most and least decided groups. These findings suggest that educational-vocational indecision has at least two dimensions. A need for different counseling approaches in dealing with uncertain students depending upon the antecedents of their uncertainty is likely. 相似文献

Subjects were trained to tap a key continuously at a specific rate, and with a specific amount of pressure (regularity task). Performance of this task was studied under conditions of: (a) decreased auditory feedback (masking noise through earphones), (b) decreased visual feedback (tapping hand screened from view), (c) vibration (vibrators applied to forearm in order to “mask” proprioceptive feedback), (d) digital block of tapping finger, and (e) combination of all four conditions. Significant changes in rate and intensity of tapping resulted under conditions of decreased auditory feedback, vibration, and the combined condition.
In the second part of the study, the effects of different delayed sensory events on keytapping were examined. The five conditions of delayed sensory feedback were: (a) delayed auditory feedback, (b) delayed visual feedback, (c) delayed tactile feedback, (d) the first three delayed sensory events presented simultaneously, and (e) condition (d) repeated with digital block of the tapping finger.
The conditions of delayed sensory feedback did not markedly alter performance of the regularity task. The same conditions of delayed sensory feedback did, however, produce highly significant changes in the performance of a more complex pattern task. All of these delay conditions produced parallel changes in the pattern task, namely increased intensity and decreased rate of tapping. The fact that the pattern task is more disturbed by delayed sensory feedback than the regularity task suggests that temporal complexity of the task is one determinant of the degree to which it will be disturbed by a delay in sensory feedback. 相似文献

A method is derived for finding the average Spearman rank correlation coefficient ofN sets of ranks with a single dependent or criterion ranking ofn items without computing any of the individual coefficients. Procedures for calculating the exact distribution of
av for small values ofN andn are described for the null case. The first four moments about zero of this distribution are derived, and it is concluded that for samples as small asN=4 andn=4 the normal distribution can be used safely in testing the hypothesis
av=0.This problem first came to the writer's attention in discussions with Dr. Dean J. Clyde. 相似文献

This study tested the hypothesis that the mother-father coalition, parent-child coalitions, and parental warmth expressed toward the child are associated with family problem solving in families with a preadolescent child referred for treatment of behavior problems (n = 30 ), families with a child at-risk for conduct disorder (n = 68 ), and a sample of comparison families (n = 90 ). Referred and at-risk families displayed less effective problem solving. A regression analysis, which controlled for gender of the child, family structure, family income, marital satisfaction, and severity of child problems, showed that strong parental coalitions were linked to low levels of family problem solving in at-risk and referred families. Parent-child coalitions had little apparent impact while parental warmth was highly correlated with better family problem solving. The results may be interpreted as evidence for a tendency for parents in at-risk and referred families to “scapegoat” a preadolescent during family problem-solving sessions. This may undermine progress on family problem solutions and may complicate family-based prevention and treatment programs that use family problem-solving sessions. 相似文献
