The results of a recent perceptual study (W. Ziegler & D. von Cramon, 1985, Anticipatory coarticulation in a patient with apraxia of speech. Brain and Language 26, 117-130) provided evidence for disturbed coarticulation in verbal apraxia. Further support for this finding is now provided by acoustic analyses. Formant frequencies and LP reflection coefficients were chosen to assess anticipatory vowel-to-vowel coarticulation and vowel anticipation in stop consonants, respectively. These parameters revealed a lack of coarticulatory cohesion in the speech of a patient suffering from verbal apraxia, explainable by a consistent delay in the initiation of anticipatory vowel gestures. The findings are discussed with respect to prosodic features and to theoretical and clinical concepts of verbal apraxia. 相似文献

Agreement between adolescents, mothers, fathers, and teachers on adolescents' personality traits was investigated in a longitudinal study. The targets for personality ratings were the adolescents who participated in the European Youth Heart Study in Estonia. There were 593 participants in the first wave and 480 participants in the follow-up study 3 years later. Adolescents' self-reports as well as father, mother, and teacher ratings were collected using questionnaires to measure the five-factor model of personality. In both waves, inter-rater agreement was highest between mothers and fathers, was low to moderate for parent-self ratings, and was lowest for ratings between self and teacher, mother and teacher, and father and teacher. Test-retest correlations were moderate for parent and self-ratings but failed to reach statistical significance for three of the five teacher-rated traits, suggesting lower reliability of teacher ratings. Possible explanations for the low agreement between teachers and other judges are discussed. 相似文献

In this study, a stress management program based on cognitive behavioural therapy principles was compared with a Kundaliniyoga program. A study sample of 26 women and 7 men from a large Swedish company were divided randomly into 2 groups for each of the different forms of intervention; a total of 4 groups. The groups were instructed by trained group leaders and 10 sessions were held with each of groups, over a period of 4 months. Psychological (self-rated stress and stress behaviour, anger, exhaustion, quality of life) and physiological (blood pressure, heart rate, urinary catecholamines, salivary cortisol) measurements obtained before and after treatment showed significant improvements on most of the variables in both groups as well as medium-to-high effect sizes. However, no significant difference was found between the 2 programs. The results indicate that both cognitive behaviour therapy and yoga are promising stress management techniques. 相似文献

A crucial demand in dual tasks suffering from a capacity limited processing mechanism is task-order scheduling, i.e. the control of the order in which the two component tasks are processed by this limited processing mechanism. The present study aims to test whether the lateral prefrontal cortex (LPFC) is associated with this demand. For this, 15 participants performed a psychological refractory paradigm (PRP) type dual task in an event-related functional magnetic resonance (fMRI) experiment. In detail, two choice reaction tasks, a visual (response with right hand) and an auditory (response with left hand), were presented with a temporal offset of 200 ms, while the participants were required to respond to the tasks in the order of their presentation. Importantly, the presentation order of the tasks changed randomly. Based on previous evidence, we argue that trials in which the present task order changed as compared to the previous trial (different-order trials) impose higher demands on task coordination than same-order trials do. The analyses showed that cortical areas along the posterior part of the left inferior frontal sulcus as well as the right posterior middle frontal gyrus were more strongly activated in different-order than in same-order trials, thus supporting the conclusion that one function of the LPFC for dual-task performance is the temporal coordination of two tasks. Furthermore, it is discussed that the present findings favour the active scheduling over the passive queuing hypothesis of dual-task processing. 相似文献

The risk of experiencing adverse financial events (e.g. bankruptcy) depends on the world economy and on individual differences in financial and psychological variables. Analysing data from 109,472 British survey respondents, this study reports the risks associated with financial capabilities, money attitudes, and socio-economic status for suffering negative financial outcomes. The results show that (1) socio-economic status is associated with financial capabilities but not with money attitudes; (2) money attitudes and financial capabilities are largely independent; (3) money attitudes and financial capabilities each contribute independently to the risk of experiencing adverse financial outcomes, even after adjusting for socio-economic status; and (4) financial capabilities are greater risk factors of adverse financial outcomes than money attitudes; the latter, however, are likely to be promising targets for interventions. 相似文献

In this paper, an overview of the observed-score equating (OSE) process is provided from the perspective of a unifying equating framework (von Davier in von Davier (Ed.), Statistical models for test equating, scaling, and linking, Springer, New York, pp. 1–17, 2011b). The framework includes all OSE approaches. Issues related to the test, common items, and sampling designs and their relationship to measurement and equating are discussed. Challenges to the equating process, model assumptions, and approaches to equating evaluation are also presented. The equating process is illustrated step-by-step with a real data example from a licensure test. 相似文献
