The recognition and proper evaluation of Vietnam veterans' demonstrating Post-Traumatic Stress Disorder syndromes is reviewed. The special problems of accurate diagnosis and assessment of former Vietnam combatants is emphasized. The forensic evaluation of Vietnam veterans' raising the Post Traumatic Stress Disorder syndrome in either civil or criminal proceedings is comprehensively discussed. The question “What are the clinical techniques necessary to accomplish a competent forensic evaluation of the Vietnam veterans?” is specifically addressed with special emphasis on legal dispositions and treatment implications. The relationship between the criminal acts of combat veterans and their exposure to the psychological trauma of war is explored. 相似文献

Several tasks were interpolated during the intertrial interval (ITI) of a concept identification (CI) task. In Experiment I, 234 subjects were required to count backwards by threes, emit a sibilant, or to refrain from thinking after all responses, after correct responses, or after errors. Counting backwards interfered with performance, but only if it occurred after errors. Stimulus and feedback information was either withheld, as in Experiment I, or made available during the ITI in Experiment II. Results of the data from 280 subjects indicated that counting backwards interfered with performance only when interpolated after errors, when stimulus-feedback information was withheld, but had an equivalent effect after errors and correct responses when stimulus-feedback information was available during ITI, indicating that different strategies were induced by the presence of such information. 相似文献

Two major findings were obtained in a study of college students' recall of meaningful grammatical relations within sentences: (1) verb-object relations in object focus relative clauses were recalled less accurately than verb-object relations in subject focus relative clauses, thus supporting the hypothesis that permuted word order in certain relative clauses interferes with adequate encoding of underlying grammatical relations, and (2) subject-verb relations in nested sentences in which a relative clause intervened between subject and verb (nested sentences) were retained in memory as accurately as uninterrupted subject-verb relations (not nested sentences). 相似文献

Using both recognition and recall responses, confusion and intrusion errors were obtained for briefly exposed 11-letter strings. The patterns of errors were sharply dependent upon experimental variables. In Experiment I Ss made auditory and visual intrusions with recall, but neither with recognition. In Experiment II increasing exposure time and eliminating a poststimulus cue primarily increased auditory confusions. This suggests that auditory and visual confusions reflect strategy-contingentrecoding rather than modality-specificencoding. 相似文献

The present paper describes a discontiguous S-R automated primate discrimination apparatus (APDA) designed to eliminate the stimulus sampling biases associated with previous manual and automated testing procedures and at the same time to provide greater specification of the S's intratrial discrimination behavior. Data from two simultaneous color discrimination problems are summarized as an evaluation of the current design. 相似文献

Evaluation of factor analytic research procedures by means of simulated correlation matrices 总被引:1,自引:0,他引:1
In order to study the effectiveness of factor analytic methods, a procedure was developed for computing simulated correlation matrices which are more similar to real data correlation matrices than are those matrices computed from the factor analysis structural model. In the present investigation, three methods of factor extraction were studied as applied to 54 simulated correlation matrices which varied in proportion of variance derived from a major factor domain, number of factors in the major domain, and closeness of the simulation procedure to the factor analysis structural model. While the factor extraction methods differed little from one another in quality of results for matrices more dissimilar to the factor analytic model, major differences in quality of results were associated with fewer factors in the major domain, higher proportion of variance from the major domain, and closeness of the simulation procedure to the factor analysis structural model.The research was jointly supported by the University of Illinois and the office of Naval Research under contracts Nonr 1834(39) and N00014-67-A-0305-0003. 相似文献

The Ss made choice responses under three experimental conditions: (1) a variable interval between the warning signal and the signal to respond, (2) a constant interval between the warning signal and the signal to respond, and (3) omission of the warning signal. With variable intersignal intervals (lSI), response time (RT) was inversely related to lSI at least when the latter was in the 10 to 225 msec range. When lSI was constant its duration had no perceptible effect on RT. RT tended to be shorter with constant lSI. independent of its duration, than when the warning signal was omitted altogether. 相似文献
