Three experiments assessed kindergartners' performance on simple conceptlike problems in which the correct solution could be selected from a specified set of possible solutions by using the information provided by a single positive or negative stimulus. For both positive and negative instances, performance was accurate when all stimulus attributes were logically informative, but performance was impaired when stimuli included an additional, logically uninformative, attribute. This impairment could not be attributed simply to increased information processing load. Children seemed to realize that uninformative attributes provided no basis for choosing among possible solutions, but did not seem to understand how to interpret this fact in order to make appropriate inferences. It was suggested that children's inferential deficit may result from a failure to understand how the relationships that exist between two sets of information are coordinated with the relationships that exist among the parts of each set. Implications were discussed for kindergartners' performance on more complex concept problems. 相似文献

Currently, many different strategies are employed by respected professionals working in the area of therapy for persons who stutter. This phenomenon serves as a point of departure for reflections on the nonspecific elements involved in therapy. Drawing on the literature of holistic medicine and psychotherapy these elements are identified as follows: (1) active participation of the client in the therapy process; (2) role of self-management skills; (3) influence of client's expectations regarding treatment; (4) suggestion as a factor in therapy; and (5) the therapeutic relationship. 相似文献

Student perceptions of barriers, facilitating factors, and information needs related to the consideration of careers in science and technology were investigated with a nationwide sample of talented high school senior women (N = 1017). Data were collected through a mailed questionnaire as part of a broader National Science Foundation project. Results of the study suggest that relatively few girls choose careers in science and technology because: They have doubts about combining family life with a science career; they lack information about steps in preparing for a science career; they believe influential adults; and they see few examples of the important role women can play in science. The data describing the students' perceptions of facilitating factors and information needs suggest that encouragement from family, access to role models, extra help and encouragement from science teachers, and information about careers in science, including the steps involved in preparation, might be influential in helping change perceptions of barriers to careers in science and technology. 相似文献

Eighteen aphasics and seven normal controls were examined as to their ability to comprehend utterances when correct interpretation required integration of extralinguistic cues in a natural setting. Videotaped situations were presented in which the correct interpretation of an utterance was not the literal interpretation but was the meaning conveyed by the request in a particular context. The aphasics' performance with indirect requests was superior to their performance on a standard battery of auditory comprehension tasks. Standard tests of auditory language comprehension, therefore, offer a measure of aphasic breakdown in linguistic processing but do not adequately reflect aphasics' receptive abilities in natural communicative settings. When the aphasic subjects did demonstrate difficulties with natural settings, their difficulty was, in part, a function of their level of performance on the standard battery. In addition, when the linguistic element of the communicative setting conveyed negative intent, aphasics were further reduced in their ability to interpret a message correctly. Otherwise, the aphasic subjects performance resembled that of the normal controls in that they demonstrated the capacity to utilize extralinguistic cues to discern correctly the conveyed intent in many requests. 相似文献

Three experiments are reported which examine the effects of experience with escapable shock either subsequent to (Experiment 1) or prior to (Experiments 2 and 3) a session of inescapable shock on the subsequently produced long-term analgesic reaction in rats. Experment 1 demonstrated that experience with escapable shock 4 hr after a session of inescapable tail shock completely reverses the analgesic response that is normally observed 24 hr later upon reexposure to shock. The escapability of the shock was shown to be the important factor in reversing the analgesic reaction, since subjects given inescapable shock in amounts equivalent to escape subjects exhibited no reduction in analgesia. Experiment 2 showed that experience with escapable shock 4 hr prior to a session of inescapable tail shock could also completely eliminate the long-term analgesic reaction. Experiment 3 replicated the results of Experiment 2, but employed a different escape task and temporal parameters in order to extend the generality of the findings, and to more closely match the procedures employed in behavioral experiments reported by J. L. Williams and S. F. Maier (Journal of Experimental Psychology: Animal Behavior Processes, 1977, 3, 240–253). The implications of these results for the areas of pain control and learned helplessness were discussed. 相似文献

Rats 30, 60, 90, and 120 days of age were fed 105 45-mg food pellets on a noncontingent VT 70-sec schedule during 14 daily 2-hr sessions. Every animal became polydipsic on this schedule when compared with a schedule in which 105 pellets were presented at the beginning of the session. Mean polydipsic ratios (schedule intake/control intake) ranged from 2.9–5.4. Water intakes (milliliters per 100g body weight) did not differ during the last five sessions as a function of age. The results are discussed with respect to the generality of the class of adjunctive behaviors. 相似文献

Social skills training for juvenile delinquents 总被引:2,自引:0,他引:2
Thomas H. Ollendick 《Behaviour research and therapy》1979,17(6):547-554
Twenty-seven incarcerated juvenile delinquents matched on the number of previous offenses, age, WISC-R IQ, and locus of control were assigned to a Social Skills. Discussion or Control group. Social skills training consisted of instruction, feedback, modeling, behavior rehearsal, social reinforcement and graduated homework assignments. All subjects were assessed before and after treatment on a variety of self-report, role-play and behavioral measures. Analyses of variance for difference scores indicated that the Social Skills group improved significantly more than the Discussion and Control groups, which did not differ. Appropriate interpersonal skills were learned, state anxiety was reduced, internal locus of control was increased, and significant shifts in adjustment to the institutional program were evidenced for the Social Skills group. 相似文献
