Abstract

Academic buoyancy refers to a positive, constructive, and adaptive response to the types of challenges and setbacks experienced in a typical and everyday academic setting. In this project we examined whether academic buoyancy explained any additional variance in test anxiety over and above that explained by coping. Two hundred and ninety-eight students in their final two years of compulsory schooling completed self-report measures of academic buoyancy, coping, and test anxiety. Results suggested that buoyancy was inversely related to test anxiety and unrelated to coping. With the exception of test-irrelevant thoughts, test anxiety was positively related to avoidance coping and social support. Test-irrelevant thoughts were inversely related to task focus, unrelated to social support, and positively related to avoidance. A hierarchical regression analysis showed that academic buoyancy explained a significant additional proportion of variance in test anxiety when the variance for coping had already been accounted for. These findings suggest that academic buoyancy can be considered as a distinct construct from that of adaptive coping.  相似文献

The authors describe the inception and subsequent testing of a questionnaire on attitudes regarding how psychotherapy ought to be pursued: the Valuable Elements in Psychotherapy Questionnaire (VEP-Q). A sample of 416 Swedish therapists (161 psychodynamic, 93 cognitive, 95 cognitive behavioral, and 67 integrative/eclectic) responded to the 17-item VEP-Q. A factor analysis of these items resulted in three subscales: PDT, CBT, and Common Factor, as validated by analyses of covariance. The internal consistency and test–retest reliability of the scales were excellent. In addition to theoretical orientation, variables such as gender and basic professional training influenced how respondents answered the VEP-Q. The authors conclude that the VEP-Q seems to be an appropriate instrument for describing similarities as well as differences among practitioners of various schools of psychotherapy.  相似文献

Oral narrative retelling is often problematic for children with communicative and neurodevelopmental disorders. However, beyond a suggested role of language level, little is known about the basis of narrative performance. In this study we examine whether oral narrative retelling might be associated not just with language level but also with skills related to nonverbal narrative temporal sequencing. A diagnostically heterogeneous sample of Swedish‐speaking children with a full scale IQ >70 was included in the study (N = 55; age 6–9 years). Narrative retelling skills were measured using the three subscores from the bus story test (BST). Independent predictors included (1) temporal sequencing skills according to a picture arrangement test and (2) a language skills factor consisting of definitional vocabulary and receptive grammar. Regression analyses show that language skills predicted BST Sentence Length and Subordinate Clauses subscores, while both temporal sequencing and language were independently linked with the BST Information subscore. When subdividing the sample based on nonverbal temporal sequencing level, a significant subgroup difference was found only for BST Information. Finally, a principal component analysis shows that temporal sequencing and BST Information loaded on a common factor, separately from the language measures. It is concluded that language level is an important correlate of narrative performance more generally in this diagnostically heterogeneous sample, and that nonverbal temporal sequencing functions are important especially for conveying story information. Theoretical and clinical implications are discussed.  相似文献

Over the years, research in the social sciences has been dominated by reporting of reliability coefficients that fail to account for key sources of measurement error. Use of these coefficients, in turn, to correct for measurement error can hinder scientific progress by misrepresenting true relationships among the underlying constructs being investigated. In the research reported here, we addressed these issues using generalizability theory (G-theory) in both traditional and new ways to account for the three key sources of measurement error (random-response, specific-factor, and transient) that affect scores from objectively scored measures. Results from 20 widely used measures of personality, self-concept, and socially desirable responding showed that conventional indices consistently misrepresented reliability and relationships among psychological constructs by failing to account for key sources of measurement error and correlated transient errors within occasions. The results further revealed that G-theory served as an effective framework for remedying these problems. We discuss possible extensions in future research and provide code from the computer package R in an online supplement to enable readers to apply the procedures we demonstrate to their own research.  相似文献

In this study, attentional processing in relation to mindfulness meditation was investigated. Since recent studies have suggested that mindfulness meditation may induce improvements in attentional processing, we have tested 20 expert mindfulness meditators in the attention network test. Their performance was compared to that of 20 age- and gender-matched controls. In addition to attentional network analyses, overall attentional processing was analysed by means of efficiency scores (i.e., accuracy controlled for reaction time). Better orienting and executive attention (reflected by smaller differences in either reaction time or error score, respectively) were observed in the mindfulness meditation group. Furthermore, extensive mindfulness meditation appeared to be related to a reduction of the fraction of errors for responses with the same reaction time. These results provide new insights into differences in attentional processing related to mindfulness meditation and suggest the possibility of increasing the efficiency in attentional processing by extensive mental training.  相似文献

ABSTRACT

The study of memory for famous people and visual imagery retrieval was investigated in patients in the early stages of Alzheimer's disease (AD) and in the prodromal stage of AD, so-called Mild Cognitive Impairment (MCI). Fifteen patients with AD (MMSE ≥23), 15 patients with amnestic MCI (a-MCI) and 15 normal controls (NC) performed a famous names test designed to evaluate the semantic and distinctive physical features knowledge of famous persons. Results indicated that patients with AD and a-MCI generated significantly less physical features and semantic biographical knowledge about famous persons than did normal control participants. Additionally, significant differences were observed between a-MCI and AD patients in all tasks. The present findings confirm recent studies reporting semantic memory impairment in MCI. Moreover, the current findings show that mental imagery is lowered in a-MCI and AD and is likely related to the early semantic impairment.  相似文献

根据可用性测试过程中用户皮肤电水平(skin conductance level,SCL)的变化,提出了基于总体平均经验模式分解(ensemble empirical mode deeomposition,EEMD)技术的用户SCL信号趋势和变化特征提取方法。首先,应用EEMD技术对SCL信号进行分解,得到若干独立的基本模式分量及趋势项;然后,对基本模式分量进行显著性检验,进而实现信号的去噪去趋势重构,得到用户SCL的变化特征。实验结果表明:界面的可用性问题使得用户SCL单调趋势变得不明显;当用户遇到可用性问题时,SCL去噪去趋势重构信号波动幅度明显变大,Wilcoxon符号秩检验表明不同阶段用户SCL去噪去趋势重构信号功率差异显著。因此,基于EEMD的信号处理方法能有效支撑可用性测试过程中用户SCL变化的分析。  相似文献

Two studies examined the relationship between cadets' views toward women, specifically, attitudes about fitness testing at the United States Air Force Academy (USAFA). Cadets completed measures of views toward women in society, in the military, at USAFA, and fitness testing. Results revealed that many male cadets held sexist attitudes of women in all categories. Cadets who held egalitarian views of women in society and in the military were more likely to support equitable fitness standards. Furthermore, cadets' personal viewpoints differed from their perception of the entire cadet population viewpoint, creating an environment of pluralistic ignorance. That is, cadets believed the collective was more sexist than themselves, suggesting that a vocal minority who perpetuate sexist attitudes may hinder changes in culture.  相似文献

Subjects who pretested high or low in hypnotic suggestibility took a creativity test either under hypnosis or in a waking state. All subjects made a global estimate of their general degree of creativity. Greater figural-spatial creativity was exhibited in the hypnosis condition than in the waking condition by both high and low suggestibles. Creativity self-reports were not corroborated by actual creative performance.  相似文献

The statistical significance levels of the Wilcoxon-Mann-Whitney test and the Kruskal-Wallis test are substantially biased by heterogeneous variances of treatment groups—even when sample sizes are equal. Under these conditions, the Type I error probabilities of the nonparametric tests, performed at the .01, .05, and .10 significance levels, increase by as much as 40%-50% in many cases and sometimes as much as 300%. The bias increases systematically as the ratio of standard deviations of treatment groups increases and remains fairly constant for various sample sizes. There is no indication that Type I error probabilities approach the significance level asymptotically as sample size increases.  相似文献
