The principles, design considerations, and components of a clinical information system intended to support and enhance the patient care, educational, and research missions of a comprehensive psychiatric institute are presented. Major characteristics of the system are its emphases on efficiency, simplicity, and intensive user involvement throughout the development of the system. 相似文献

3 groups of university freshmen took the SAT-V before and after a course in Accelerated Reading. The mean post-test scores for 2 groups increased slightly less than 10 points, while the mean post-test score for the third group decreased significantly. It is concluded that for the type of students used in this study, a course emphasizing speed and accuracy of reading is not of value in increasing scores on the verbal part of the Scholastic Aptitude Test. 相似文献

Respiratory sinus arrhythmia (RSA) is a quantitative metric that reflects autonomic nervous system regulation and provides a physiological marker of attentional engagement that supports cognitive and affective regulatory processes. RSA can be added to executive function (EF) assessments with minimal participant burden because of the commercial availability of lightweight, wearable electrocardiogram (ECG) sensors. However, the inclusion of RSA data in large data collection efforts has been hindered by the time-intensive processing of RSA. In this study we evaluated the performance of an automated RSA-scoring method in the context of an EF study in preschool-aged children. The absolute differences in RSA across both scoring methods were small (mean RSA differences = –0.02–0.10), with little to no evidence of bias for the automated relative to the hand-scoring approach. Moreover, the relative rank-ordering of RSA across both scoring methods was strong (rs = .96–.99). Reliable changes in RSA from baseline to the EF task were highly similar across both scoring methods (96%–100% absolute agreement; Kappa = .83–1.0). On the basis of these findings, the automated RSA algorithm appears to be a suitable substitute for hand-scoring in the context of EF assessment. 相似文献

This study examines how consuming alcohol differentially affects the communicative behavior and perceptions of high and low social self‐esteem (SSE) women as they engage in a brief interaction with a flirtatious male. Alcohol myopia theory proposes that alcohol affects behavior when it blocks a person's normal inhibitions about enacting a behavior. It was predicted that low SSE women would be more inhibited when talking to a flirtatious male than would high SSE women and, therefore administration of a social self‐esteem measure and random assignment to an alcoholic or nonalcoholic beverage condition, participants (N=50) talked with an attractive, flirtatious male confederate. Low SSE women were less anxious and self‐disclosed more when drinking than when sober, whereas high SSE women were not significantly affected by alcohol consumption. The discussion highlights the complex and often contradictory effects of alcohol consumption on social interaction. 相似文献

In this paper, I consider some issues involving a certain closure principle for Structural Justification, a relation between
a cognitive subject and a proposition that’s expressed by locutions like ‘S has a source of justification for p’ and ‘p is
justifiable for S’. I begin by summarizing recent work by Peter Klein that advances the thesis that the indicated closure
principle is plausible but lacks Skeptical utility. I then assess objections to Klein’s thesis based on work by Robert Audi
and Anthony Brueckner. One finding is that the typical statement of the relevant closure principle can express a number of
different closure principles, and that recognizing this helps to resolve certain disputes. 相似文献

Despite a hundred years of questionnaire testing, no consensus has been reached on the optimal number of response alternatives
in rating scales. Differences in prior research may have been due to the use of various psychometric models (classical test
theory, item factor analysis, and item response theory) and different performance criteria (reliability, convergent/discriminant
validity, and internal structure of the questionnaire). Furthermore, previous empirical studies on this issue have tackled
the experimental design from a between-subjects perspective, thus ignoring intra-individual effects. In contrast with this
approach, we propose a within-subjects experimental design and a comprehensive statistical methodology using structural equation
models for studying all of these aspects simultaneously, therefore increasing statistical power. To illustrate the method,
two personality questionnaires were examined using a repeated measures design. Results indicated that as the number of response
alternatives increased, (1) internal consistency increased, (2) there was no effect on convergent validity, and (3) goodness
of fit worsened. Finally, the article assesses the practical consequences of this research for the design of future personality
questionnaires. 相似文献
