An experimental study was conducted to examine phonetic and phonemic deficits in the speech production of aphasics. Subjects included four Broca's aphasics, four Conduction aphasics, five Wernicke's aphasics, one nonaphasic dysarthric patient, and four normal controls. The subjects read a list of words containing word-initial stop consonants which were subsequently measured acoustically for voice-onset time. The results showed that Broca's aphasics exhibit a more severe production disorder than Conduction aphasics who in turn exhibit a more severe disorder than Wernicke's aphasics, in accord with clinical observations. In addition, although Broca's aphasics produced both phonetic and phonemic errors, the results showed that they have a pervasive phonetic disorder which affects their correct target productions as well as the total number of phonetic errors produced. This deficit however seems to be a speech deficit rather than a low-level motor control problem. In contrast, the Wernicke's aphasics show a deficit characterized by isolated phonemic mistargeting errors. Finally, the pattern of productions for the Conduction aphasics indicates that some patients show a predominantly phonetic disorder similar to the Broca's aphasics and others show predominantly a phonemic disorder similar to the Wernicke's aphasics. 相似文献

A logit vector model and a logit ideal point model are presented for external analysis of paired comparison preference judgments aggregated over a homogeneous group. The logit vector model is hierarchically nested within the logit ideal point model so that statistical tests are available to distinguish between these two models. Generalized least squares estimation procedures are developed to account for heteroscedastic sampling error variances and specification error variances. Two numerical illustrations deal with judgments concerning employee compensation plans and preferences for salt and sugar in the brine of canned green beans. 相似文献

Three Machiavellian (Mach) scales together with measures of authoritarian personality, the EPQ and the 16PF test were subjected to a rotated factor analysis in order to identify and locate in personality space a Mach factor or factors. One Mach factor was identified independent of the main personality factors. 相似文献

ABSTRACT In this study we examined 15 personality and demographic differences between psychology students who took part in experiments at different times of the semester and different times of the day. In general, few significant relations were found and those that did emerge were small in magnitude. Females and freshmen signed up for experiments earlier in the semester. Females took part in their first experiment earlier in the semester, as did students who were Protestant and who came from smaller home towns. Students low in self-consciousness also tended to begin participating earlier. Extraverts participated earlier in the day than introverts. Results generally were consistent with previous findings of differences between research volunteers and non-volunteers. However, it was concluded that because of their small magnitude and inconsistency from site to site, with a few precautions experimenters probably need not be concerned that timing effects threaten the external validity of psychological research outcomes. 相似文献

In three experiments, subjects were asked to memorize related phrase pairs and then to produce one of these phrases from a cue. In Experiment 1, it was found that both memorization times and response latencies increased with the number of words that differed between the phrases. In Experiment 2 and 3, it was shown that the presence of a strong modifying or semantic relationship between words in one phrase influenced both memorization time and response latency when those same words were contrasted between the two phrases. The implications of the results for models of storage, retrieval, and planning of speech are considered. 相似文献

In the first experiment, in which two successively presented free-form visual patterns varied in their similarity to each other, subjects had to decide, in one condition, if the patterns were “identical” and in two other conditions if the patterns were “similar.” Qualitative individual differences in the effect of similarity on the time required to make a decision were found in the “identity” condition, and these differences interacted with the “similarity” conditions. The individual differences and the experimental effects are interpreted in terms of a two-process model of the visual comparison process—a holistic matching process that is sometimes accompanied by an analytic difference detection process. In the second experiment, the same subjects repeatedly categorized subsets of the free-form visual patterns on the basis of similarity. There appeared to be no individual differences in the subjects’ perceptions of similarity, but subjects’ perceptions did differ from the assumptions made by the experimenters when they established the response criteria for the first experiment. 相似文献

Results indicated that. over a 6-week test-retest interval, outpatient male alcohol abusers' self-reports of their daily drinking, alcohol-related incarcerations and their drinking problem history were highly reliable (r = +0.79 to +0.98). Limits on the generalizability of these finclings are discussed. 相似文献

The psychiatric treatment of adolescents is analyzed as having, on the one hand, staff and client subsystems interacting continuously and, on the other hand, cross-boundary transactions between the treatment program and two other systems, the neighborhood and the community mental health system of which the program is a part. Through the use of the concepts of boundaries and mirroring, it is possible to explain more clearly how certain dramatic events relate to adolescent psychology and to the treatment tasks. 相似文献

The desirability of control 总被引:4,自引:0,他引:4
The psychological construct of desirability of control was related to several theoretical statements (e.g., Kelley, 1971; White, 1959) and areas of current research (e.g., Glass & Singer, 1972; Deci, 1975) in psychology. A scale designed to measure individual differences in the general level of motivation to control the events in one's life was presented. The Desirability of Control Scale was found to have substantial internal consistency (.80) and test-retest reliability (.75), as well as discriminant validity from measures of locus of control (Rotter, 1966) and social desirability (Crowne & Marlowe, 1960). The results of an illusion of control study (cf. Langer, 1975) provided construct validation: only subjects high in the desire for control displayed a belief in personal control over chance outcomes. Construct validation was also provided from studies on learned helplessness and hypnosis. The practical, as well as theoretical, value of the instrument was discussed.This research was facilitated by National Science Foundation grant BNS78-08834 to Harris Cooper. 相似文献
