Previous research has shown that perceived odor strength does not vary with flow rate of an odorant vapor entering the naris when that variation is produced by subject-controlled changes in sniff pressure, but that it does vary with flow rate when the variation is produced by experimenter-controlled changes in the resistance of the olfactometric system. We have suggested an odor-constancy model in which invariance of perceived odor strength is linked to perceived effort of sniffing, and have hypothesized that changed resistance will have its effect because there is no corresponding change in perceived effort when sniff pressure is held constant. In two studies, subjects made magnitude estimations of the perceived effort of sniffing; sniff pressure was controlled by having the subject match his sniff, displayed on a storage oscilloscope face, to a pattern specifying its required shape, duration, and level. In Experiment 1, resistance was fixed while sniff pressure varied; perceived effort grew as the .8 power of the required sniff pressure. In Experiment 2, sniff pressure and resistance were varied in a factorial design; perceived effort grew as the .8 power of pressure at fixed resistance, but remained unchanged when resistance varied at fixed pressure. This outcome provides indirect support for the odor-constancy model, since it shows that perceived effort covaries with flow rate under the condition in which constancy is found but does not change under the condition in which constancy fails.  相似文献

Individual therapists who begin doing family therapy often encounter some special difficulties directly related to their prior training and experience. Some therapeutic techniques of individual therapy, such as understanding and explaining the patient's problems on the basis of faulty parenting, must be relinquished and alternative means of alleviating guilt must be adopted. In doing family therapy individual therapists must adapt to the fact that they are less important than they are used to being and have less control over content and emotional tone of sessions. They must change their conceptions about the importance of privacy and secrecy. This article discusses some of the problems encountered when one is not thoroughly committed to a family therapy approach to treatment. Countertransference difficulties, problems stemming from wanting change, and the differing nature of the gratifications in the two therapeutic modalities are other topics discussed.  相似文献

The study investigated how the sincerity of models affects their influence, using a delay-of-reward paradigm. Subjects were 40 fifth and sixth graders (ages 9 and 10 years, respectively), selected for delayed gratification patterns. In the experimental manipulation, sincerity or insincerity was explicitly attributed to the model or, in a neutral-model condition, no information about the model's sincerity was given. Subjects then observed the symbolically presented model's immediatereward choices, opposed to their own preferences. Immediately after treatment, children in all model conditions and in a fourth, no-model control group responded to a second delay-preference test. It was found that the influence of models varied substantially as a function of experimentally attributed sincerity. Insincere models had considerably less effect than sincere and neutral models, who provoked substantial and equivalent changes. Insincere models did not evoke significantly different change than occurred in the control group. A postexperimental inquiry showed the experimental manipulation had affected perceptions of the model's sincerity and liking for the model, with the insincere model rated considerably lower than the sincere and neutral models. The relevance of cognitive appraisal in observational learning was discussed.  相似文献

Ellen Lenney 《Sex roles》1979,5(6):703-719
It is proposed that the field of research on psychological androgyny has entered a crucial period during which its development will not be optimal unless the following problems are recognized and corrected for: (a) the dangers of too rigidly held values; (b) the prevalence of dubious definitional assumptions; (c) the pervasity of diffuse and/or atheoretical research directions; and (d) alienation from certain basic concerns in mainstream personality research. The origins and nature of each of these problems are discussed, and in each case recommendations for future research are made. Finally, broad outlines are proposed for an idiographic model of sex roles designed to increase the predictive utility of assessment in the area of androgyny research.  相似文献

Major problems and ideas raised by the articles in this special issue are discussed, with an emphasis upon their implications for the productive development of androgyny research. First, the various methods of scoring a given sex-role inventory differ in their definitions of androgyny and in their underlying models of the relationships among masculinity, femininity, and other variables. Accordingly, recommendations for the judicious use of scoring methods are made. Second, adjustment differences between androgynous and sex-typed individuals are discussed, and researchers are urged to determine the specific aspects of sex roles which may be dysfunctional in particular settings. Third, attention is drawn to new methodologies and new content areas for androgyny research. Finally, the implications of the historical and cultural location of this research area for its status as a scientific enterprise are discussed.  相似文献

The study reports relationships between teachers' belief systems (Harvey), a teacher-pupil interaction measure of classroom influence, pupils' perception of the dimate of the dassroom, and pupils' academic achievement. Results demonstrate that more complex teachers encourage more pupil influence, and are perceived as having a more origin climate. In classrooms of high pupil influence and perceived origin climate, the pupils have higher academic achievement. These results are discussed in terms of the theory of personal causation and are cited as evidence for the value of the study of action sequences as related to verbal-utterances of the actors.  相似文献

This study examined the relationship between auditory recall and dysfluent behavior in children. Subjects were 11 stutterers and 11 nonstutterers, ages 4.9–11.10. The Auditory Sequential Memory subtest of the ITPA and the Auditory Attention Span for Related Syllables subtest of the Detroit Test of Learning Aptitudes were administered to both groups. Results indicated that scores on the ITPA were not significantly different. Comparison of the group's scores on the DTLA were highly significant with the control group's scoring 35 months higher. After 6 months of therapy, six children in the experimental group were fluent. Posttests revealed no significant differences on the ITPA. On the DTLA, the experimental group's mean scores significantly increased by 13.9 months. The gain in auditory recall of meaningful material substantiated the hypothesized relationship between auditory recall and dysfluency. This relationship was not viewed as causative of stuttering; data were interpreted as evidence that increased fluency allows children to use previously suppressed linguistic data.  相似文献

The investigation analyzed the phonemic paraphasic errors of 10 asphasic patients with posterior cerebral lesions. The results indicated that paraphasic speech is characterized by complex confusions, often occurring at the ends of words and often involving phonemic transpositions. Many of the unusual and unexpected phonemic errors appeared to be due to simultaneous semantic and phonologic confusions.  相似文献

On the Oldfield-Wingfield Picture-Naming Test, sensitive to subtle chronic dysphasia in adults, dyslexic children name fewer pictures correctly. Even when correct on words with less than 30 per million frequency of occurrence, they perform more slowly than do nondyslexic subjects suffering from minimal brain dysfunction (MBD) or normal controls. However, there is no evidence for “perceptual impairment” underlying dyslexic subjects' low scores and prolonged latencies, as the distribution of their errors is similar to that of normal children. Rather it is the nondyslexic MBD group which produces a high percentage of wrong names, suggestive of mistaking the pictured stimuli for other, visually similar, objects.  相似文献
