The stability of self-esteem variability: A real-time assessment

The present study investigates stability and variability as distinct features of state self-esteem change. The amount of variance attributable to stable individual differences, the association between successive self-esteem experiences, and situational and/or person × situation interaction effects were estimated in repeated measures of self-esteem whilst considering measurement invariance. N = 160 adolescents reported momentary self-esteem in an experience sampling study, (i.e., three assessments a day, over a 2-day period). Latent state-trait analysis indicate that change in state self-esteem is a stable process largely determined by interindividual differences in trait self-esteem, while the impact of occasion-specific influences is small. These intrinsic dynamics ensure consistent self-referential experiences. Results reveal experience sampling as a suitable method to track short-term changes of self-esteem.     

青少年学生焦虑敏感与睡眠质量的关系及其内在机制

采用中学生、大学生焦虑敏感问卷和匹兹堡睡眠质量指数量表(PSQI),分别对1011名中学生和607名大学生进行调查。结果显示高焦虑敏感学生的PSQI总分显著高于低焦虑敏感学生,焦虑敏感及其三个因子与PSQI的相关都是中效应,焦虑敏感对青少年学生睡眠质量指数具有显著的正向预测作用,焦虑敏感水平越高,其睡眠质量越差。焦虑敏感可能以应激事件和健康问题作为致敏源,以焦虑等负性情绪作为敏感内容,在消极自动认知觉察与思维的介入下,进一步放大对有关负性情绪的感受与体验,从而影响青少年学生的睡眠质量。     

Clarifying the role of impulsivity in dietary restraint: A structural equation modeling approach

This study was designed to clarify the relationship between the four dimensions of impulsivity in Whiteside and Lynam’s (2001) model and the two aspects of dietary restraint (Concern for Dieting and Weight Fluctuation) in a non-clinical sample. Data were collected from a volunteer community sample (N = 216) of women who responded to two self-report instruments related to impulsivity (UPPS Impulsive Behavior Scale, Whiteside & Lynam, 2001) and dietary restraint (Restraint Scale, Polivy, Herman, & Warsh, 1978). A structural equation model was tested. The model provided a good fit to the data (χ²/df = 1.64, p < .0001, RMSEA = 0.054, 90% CI = 0.050–0.058, p-value for test of close fit (RMSEA > 0.05) = .035) and revealed that Concern for Dieting was positively related to Urgency (standardized β = 0.25, p < .01). Weight Fluctuation was related to lack of Perseverance (standardized β = 0.25, p < .01) and tended to relate to Sensation Seeking (standardized β = 0.17, p = .056). Urgency and lack of Perseverance were found to play a significant role in predicting Concern for Dieting and Weight Fluctuation.     

Attentional resources in visual tracking through occlusion: the high-beams effect

A considerable amount of research has uncovered heuristics that the visual system employs to keep track of objects through periods of occlusion. Relatively little work, by comparison, has investigated the online resources that support this processing. We explored how attention is distributed when featurally identical objects become occluded during multiple object tracking. During tracking, observers had to detect small probes that appeared sporadically on targets, distracters, occluders, or empty space. Probe detection rates for these categories were taken as indexes of the distribution of attention throughout the display and revealed two novel effects. First, probe detection on an occluder’s surface was better when either a target or distractor was currently occluded in that location, compared to when no object was behind that occluder. Thus even occluded (and therefore invisible) objects recruit object-based attention. Second, and more surprising, probe detection for both targets and distractors was always better when they were occluded, compared to when they were visible. This new attentional high-beams effect indicates that the ability to track through occlusion, though seemingly effortless, in fact requires the active allocation of special attentional resources.     

类比的图式驱动效应

本研究采用了两个实验探讨了类比的图式驱动效应即类比的映射不仅是一种外显的推理过程而且也是一种内隐的推理过程,这一内隐过程具有图式驱动效应.实验1要求被试者首先阅读基础课文和目标课文然后回答问题,结果表明在课文阅读过程中存在着内隐推理.实验2采用更加复杂的实验方法检验了影响内隐推理的图式驱动效应,结果发现被试者的类比内隐推理主要受图式驱动或者结构排列的影响而很少受到语义激活或者启动效应的影响.最后,在结构排列理论与图式理论的框架中讨论了本研究的结果.     

“非典（SARS）”应激反应模式及其特征

对中国17个省市1016人面对“非典”疫情的应激反应作了调查。“高发病率区”和“其它地区”的比较发现,在SARS应激反应结构方程模型中,二者有显著差异。而在情绪障碍结构方程模型中,二者无显著差异。所建立的SARS应激反应结构方程理论模型揭示,急性的应激反应中,恐慌是最重要的内容,其次是防御反应,对疫情的认知则起了一种重要的调节、抑制的作用。抑郁和焦虑作为一个人心理健康的指数,对急性的应激反应产生一定影响,而抑郁与焦虑对急性应激反应有更大影响。社会支持作为一种缓冲器与调节器,对SARS应激反应有值得注意的影响。研究揭示了高应激反应者的特征。高恐慌者有高抑郁、焦虑和低社会支持的显著特征;高防御者则有显著的高抑郁焦虑的特征,社会支持无差异;高认知者明显地有低抑郁、高社会支持的特征。     

用结构方程建模（SEM）估计概论理论（GT）中的评分者信度

评分者的信度分析,已从经典测量理论的方法（Kendall和谐系数）发展为基于现代测量理论（如GT）的方法,但由于GT中方差分量估计的工具和途径有限,使该方法的推广受到限制。本文介绍了结构方程建模（SEM）估计GT中方差分量的必要性及原理,并通过对某省直国家机关公务员录用考试结构化面试的评分者信度分析,阐述用SEM估计概化理论中不同设计下的评分者信度研究。     

教师态度与指导方式对幼儿坚持性影响的实验研究

本研究采用3×2×2(年龄×教师态度×言语指导方式)三因素完全随机实验设计,考察了教师态度和言语指导对3~6岁幼儿坚持性的影响。其中幼儿年龄、教师态度及言语指导方式为实验的自变量,幼儿坚持完成任务的时间为实验因变量,设计4种实验情境,并随机选择沈阳市两所幼儿园,分层选取小、中、大班的幼儿作为实验研究的被试,年龄分布在3~6岁之间,每种情境下每个年龄段的有效被试各为30人,男女各半,共360人。研究结果表明:(1)3~6岁幼儿的坚持性随着年龄的增长而逐渐发展,且4~5岁是幼儿坚持性发展的转折期;(2)不同的教师态度对幼儿的坚持性影响显著;(3)不同的言语指导方式对幼儿坚持性影响显著;(4)教师积极态度下,多次言语指导对幼儿的坚持性会产生最积极的影响。     

Psychosocial environment and affective outcomes in technology-rich classrooms: testing a causal model

Research investigated classroom environment antecedent variables and student affective outcomes in Australian high schools. The Technology-Rich Outcomes-Focused Learning Environment Inventory (TROFLEI) was used to assess 10 classroom environment dimensions: student cohesiveness, teacher support, involvement, investigation, task orientation, cooperation, equity, differentiation, computer usage and young adult ethos. A sample of 4,146 high school students from Western Australia and Tasmania responded to the TROFLEI and three student outcome measures: attitude to the subject, attitude to computer use and academic efficacy. Confirmatory factor analysis using LISREL supported the 10 scale a priori structure of the instrument. Structural equation modeling using LISREL was used to test a postulated model involving antecedent variables, classroom environment and outcomes. The modeling indicated that: improving classroom environment has the potential to improve student outcomes, antecedents did not have any significant direct effect on outcomes, and academic efficacy mediated the effect of several classroom environment dimensions on attitude to subject and attitude to computer use.
