大学生主观童年创伤症状对抑郁的影响:抗挫折能力和外向性的多重中介效应

本研究将"童年创伤"定义为"个体14岁以前所经历的,站在主体的角度主观感受到的创伤性事件"。采用问卷调查法对302名大学生进行调查,通过定量加定性的方式探索了童年创伤与抑郁之间的关系。相关分析表明：主观童年创伤症状、外向性、抗挫折能力、抑郁之间两两显著相关;结构方程模型表明：主观童年创伤症状通过外向性、抗挫折能力完全、多重中介作用间接预测抑郁。本研究结果在理论和实践层面对大学生抑郁问题的预防和干预工作提供重要的借鉴依据。     

Psychometric latent response models

In this paper, some psychometric models will be presented that belong to the larger class oflatent response models (LRMs). First, LRMs are introduced by means of an application in the field ofcomponential item response theory (Embretson, 1980, 1984). Second, a general definition of LRMs (not specific for the psychometric subclass) is given. Third, some more psychometric LRMs, and examples of how they can be applied, are presented. Fourth, a method for obtaining maximum likelihood (ML) and some maximum a posteriori (MAP) estimates of the parameters of LRMs is presented. This method is then applied to theconjunctive Rasch model. Fifth and last, an application of the conjunctive Rasch model is presented. This model was applied to responses to typical verbal ability items (open synonym items).This paper presents theoretical and empirical results of a research project supported by the Research Council [Onderzoeksraad] of the University of Leuven (grant number 89-9) to Paul De Boeck and Luc Delbeke.     

Negotiating the Reality of Visual Impairment: Hope, Coping, and Functional Ability

A consecutive sample of 63 adventitiously blinded American military veterans in a interdisciplinary inpatient rehabilitation program participated in this study examining the relation of hope to self-reported functional ability level. Scores from a modified oral administration of the Hope Scale and the Millon Behavioral Health Inventory basic coping styles were used as predictor variables to test regression-based models of mediation and moderation relations to functional ability level. Results support a mediating role for hope in the relation between a proactive sociable style and perceived level of functional ability.     

Cognitive ability and communicative disability

The area of cognitive ability and communicative disability is introduced and delineated in this special issue of Scandinavian Journal of Psychology. A set of 13 chapters is included in the issue to illustrate the theoretical and methodological advances in the areas of memory and amnesia, reading and dyslexia, speech-reading, tactile speech and objects, and developmental disorders. Theoretical communalities among the different subspecialities are emphasized.     

Imagery ability classification: Commentary on «Kinaesthetic imagery ability moderates the effect of an AO+MI intervention on golf putt performance: A pilot study» by McNeill et al. (2020)

McNeill et al. (2020) recently published a study that first aimed to assess the effect of a combination of motor imagery (MI) and action observation (AO) on golf putt performance and then to determine if the evolution of this performance could be moderated by participants’ kinesthetic imagery ability. To assess golfers’ MI ability, the authors used the third version of the Movement Imagery Questionnaire. Participants notably self-estimated their kinesthetic MI ability by using a Likert-type scale, with scores ranging from 1 “very difficult to feel” to 7 “very easy to feel”. Athletes were categorized as either “poor” or “good” kinesthetic imagers, with mean scores of 4.93 and 6.63, respectively, in the intervention groups. Although a similar categorization procedure had previously been used in the literature for “good imagers”, the mean scores for “poor” imagers were much higher than those noted in previous studies evaluating the effect of MI ability on motor accuracy. Moreover, the low number of participants in the intervention group (n = 22) meant that participants were considered “poor” imagers even though their mean scores corresponded to “quite easy to feel” kinesthetic images of movements. This could notably explain the lack of differences between “poor” and “good” imagers in terms of putting performance in the intervention group. Despite these methodological limitations, the results of McNeill et al.‘s study show promising evidence for the efficacy of an AO plus MI intervention in relation to putting performance and should lead to further investigations. We suggest that research in the area of motor imagery ability include larger samples to explore, in individuals with very low imagery ability scores, the effects of the combination of AO and MI on motor performance.     

口译员的认知转换优势

口译可视为一种强化的双语转换活动。与一般双语者相比, 口译员在基于规则(rule-based)的转换与基于任务(task-based)的转换两方面都表现出了优势, 但基于任务的转换优势存在局部转换与整体监控的争议。经初步探索, 口译训练首先带来局部转换优势(单价任务的转换代价), 随后带来整体监控优势(双价任务的混合代价)。口译涉及的高强度语言转换及特殊的语言控制特性可能是影响口译员认知转换优势的因素。上述结果对双语优势及其他相关研究有启示作用。     

The testing environment as an explanation for unproctored internet‐based testing device‐type effects

Device‐type effects on cognitive tests appear to covary with whether unproctored internet‐based test (UIT) scores were obtained operationally or nonoperationally. The present study examined whether the testing environment and distractions therein—one of three contextual factors identified as plausible explanations—accounts for this covariation. Four‐hundred and twenty‐five college students were randomly assigned to one of three conditions which differed by the testing environment and device used to complete a cognitive test. Test scores did not differ between conditions despite greater distractions reported by those who tested in the distracting environment. Results were replicated within‐study, and suggest that the self‐selection and testing‐stakes hypotheses warrant subsequent empirical examination as explanations for the differences in device‐type effects observed in operational and nonoperational settings.     

Spatial offloading in multiple task monitoring

Coordinating multiple tasks requires a high degree of cognitive control, and individuals with limited executive functions often show difficulties in everyday multitasking. We tested the hypothesis that demands on executive control can be alleviated by internally representing the temporal pattern of goals and deadlines as spatial relations. In two experiments, participants completed a multitasking session by monitoring deadlines of four clocks running at different rates, along with separate tasks of executive functioning and spatial ability. In Experiment 1, individual and gender-related differences in spatial ability (mental rotation) predicted multitasking performance, beyond the contributions of both the updating and inhibition components of executive functioning, and even when spatial cues were eliminated from the layout of the monitoring task. Experiment 2 extended these findings by showing that concurrent spatial load impaired task monitoring accuracy, and that these detrimental effects were accentuated when spatial abilities were compromized due to fluctuation in female sex hormones. These findings suggest that multiple task monitoring involves working memory-related functions, but that these cognitive control demands can be offloaded by relying on spatial relation processes.
