基于模拟创伤研究范式, 采用道路交通事故影片对159名健康大学生进行模拟创伤, 考察PTSD易感性人格特质(特质焦虑、特质分离和神经质)、工作记忆能力(注意控制和工作记忆容量)和创伤期间认知加工(数据驱动加工和概念加工)对模拟创伤后不同时段闪回的影响。运用结构方程模型分析数据, 结果发现:(1)数据驱动加工正向预测不同时段闪回(即时闪回、一周闪回和触发闪回)的数量、生动性、痛苦度以及一周侵入频率; (2)神经质正向预测触发闪回痛苦度, 注意控制和工作记忆容量负向预测一周侵入频率; (3)概念加工在注意控制与即时闪回痛苦度之间起中介作用。研究结果提示:数据驱动加工是创伤后不同时段闪回的主要影响因素; 概念加工主要作用于早期急性应激反应, 注意控制是其保护因素; 神经质和工作记忆能力对闪回具有较长期的影响, 且工作记忆能力具有一定的保护作用。 相似文献

Numerous developmental studies assess general cognitive ability, not as the primary variable of interest, but rather as a background variable. Raven’s Progressive Matrices is an easy to administer non-verbal test that is widely used to measure general cognitive ability. However, the relatively long administration time (up to 45 min) is still a drawback for developmental studies as it often leaves little time to assess the primary variable of interest. Therefore, we used a machine learning approach – regularized regression in combination with cross-validation – to develop a short 15-item version. We did so for two age groups, namely 9 to 12 years and 13 to 16 years. The short versions predicted the scores on the standard full 60-item versions to a very high degree r = 0.89 (9–12 years) and r = 0.93 (13–16 years). We, therefore, recommend using the short version to measure general cognitive ability as a background variable in developmental studies. 相似文献

随着年龄的增长,老年人的运动能力和执行功能,以及心理加工速度都出现不同程度的衰退。已有的研究多集中于步行与跌倒,未能统合考察运动能力、心理加工速度以及执行功能各子成分之间的关系。本研究对66名老年人的运动能力、执行功能以及加工速度进行了测试,通过经典范式对老年人四种运动能力测试(握力、30秒连续坐起、闭眼单足站立、起立行走计时)与执行功能各子成分(抑制控制、刷新功能、转换功能以及工作记忆)及心理加工速度进行了统合考察,更深入地探究了老年人运动能力与认知能力之间的关系。结果发现,在运动能力中,起立行走计时的成绩与执行功能和加工速度的关系最为密切,对起立行走计时的预测模型中加工速度权重最大。结果提示,对老年人认知功能的干预可能会影响老年人的基本运动能力。 相似文献

用创造力培养观、教学监控能力和创造性教学行为问卷对430名小学教师进行调查,考察三者之间的关系,并着重对教学监控能力在其中的中介作用进行分析。结果表明:(1)创造力培养观、教学监控能力及其各个维度对创造性教学行为都有正向预测作用;(2)教学监控能力的计划准备性、控制调节性、评价反馈性、课后反省性及作为一个整体在创造力培养观与创造性教学行为之间均具有显著的中介效应。这一发现提示教师培训工作应重视教师教学监控能力的实际增长,这样才能使教师已经接受的创造教育理念落实到创造性教学行为上。 相似文献

Recent models of anxiety disorders emphasize abnormalities in emotional reactivity and regulation. However, the empirical basis for this view is limited, particularly in children and adolescents. The present study examined whether anxious children suffer both negative emotional hyper-reactivity and deficits in cognitive emotion regulation. Participants were 49 children aged 10-17 with generalized anxiety disorder, social anxiety, or separation anxiety disorder as their primary diagnosis, as well as 42 age- and gender-matched non-anxious controls. After completing a diagnostic interview and self-report questionnaires, participants were presented with pictures of threatening scenes with the instructions either to simply view them or to use reappraisal, a cognitive emotion regulation strategy, to decrease their negative emotional response. Emotion ratings, content analysis of reappraisal responses, and reports of everyday use of reappraisal were used to assess negative emotional reactivity, reappraisal ability, efficacy and frequency. Relative to controls, children with anxiety disorders (1) experienced greater negative emotional responses to the images, (2) were less successful at applying reappraisals, but (3) showed intact ability to reduce their negative emotions following reappraisal. They also (4) reported less frequent use of reappraisal in everyday life. Implications for the assessment and treatment of childhood anxiety disorders are discussed. 相似文献

This article describes how, as theories of creativity evolved, so have measures of creativity. Measures thus reflect the theories that generated them. 相似文献

Learning the local language is important for the successful integration of immigrants. Previous research has identified a number of sociodemographic factors that are associated with the effectiveness of local language acquisition among immigrants, but little is known about the influence of psychological differences on immigrants’ local language acquisition. In the present research, individual differences in general mental ability (GMA), work search intention, and personality traits Conscientiousness and Openness were studied among recently arrived Syrian (n = 1054) and Eritrean (n = 500) refugees in the Netherlands. The results revealed that in addition to the effects of age of arrival, local length of stay, premigration educational attainment, and psychological distress, GMA and work search intention were positively associated with refugees’ local language proficiency. Additionally, work search intention was found to strengthen the effect of GMA on local language proficiency. No positive linear effects were observed for Conscientiousness and Openness. Some evidence was found for curvilinear relationships between psychological predictors and local language proficiency. Implications are discussed. 相似文献

For older adults, falls often occur when transitioning from motion to a complete stop, as the motor control required during this phase is very complex and challenging. The purpose of this study was to clarify the effect of aging on the motor control required to terminate motion. Twenty-five healthy older adults (aged >65 years) and 25 healthy young adults (20–23 years) performed a rapid stopping task while standing on a force plate. The rapid stopping task was conducted by analyzing center of pressure (COP) on the force plate during a visually guided tracking experiment. To assess the ability to terminate motion, we measured the velocity waveform for the COP, along with the reaction, propulsion, braking, and total movement times. Both the reaction and movement times of the older-adult group were significantly longer than those of the younger-adult group (all, p < 0.05). There was no significant difference between the groups in regard to the initial backward propulsion time; however, in the subsequent sequence of backward braking, forward propulsion, and backward braking, all times were longer in the older-adult group than in the younger-adult group (p < 0.05). Our results show that the series of time delays shown by older adults when initiating and terminating motion is due to not only delayed reactions but also delayed stopping. Furthermore, our findings suggest that older adults have not only a diminished propulsion ability but also a diminished braking ability. 相似文献

People's relationship between positive and negative affect varies on a continuum from relatively independent to bipolar opposites, with stronger bipolar opposition being termed affective bipolarity. Experiencing more depressive symptoms is associated with increased bipolarity, but the processes underlying this relation are not yet understood. Here, we sought to replicate this link, and to examine the role of two potential mediating mechanisms: emotion regulation ability, and trait brooding. Drawing from the Dynamic Model of Affect, we hypothesised that (a) a poor ability to regulate negative emotion, and (b) the tendency to brood over one's depressed feelings would predict stronger affective bipolarity, and mediate the relationship between depressive symptoms and affective bipolarity. To measure affective bipolarity, we calculated within-person affect correlations using two weeks of experience sampling data from a community sample (n?=?100). Mediation analyses indicated that baseline assessments of an inability to regulate negative emotions in general, but not brooding specifically, mediated the relation between depressive symptoms and affective bipolarity. These findings highlight an initial mechanism through which depressive symptoms are associated with lower emotional complexity and flexibility. 相似文献
