A hot new way to measure aggression: Hot sauce allocation

Laboratory experiments investigating aggressive behavior have operationalized and assessed aggression in a variety of ways; however, these measures are often problematic because they do not create a situation in which participants perceive potential for real harm to come to the target, there is a risk of actual harm to the target, or they are too familiar to participants. To overcome these limitations, we developed a new method for measuring aggression, specifically, the amount of hot sauce administered to a target known to dislike spicy foods. We summarize a series of experiments assessing theory‐based hypotheses regarding aggression in which this measure is employed. We then briefly consider the strengths and limitations of this new measure. Aggr. Behav. 25:331–348, 1999. © 1999 Wiley‐Liss, Inc.

Educational Psychology Theory and the Promotion of Dental Care for Children Aged Five to Six

The aim of this article is to illustrate the value of educational psychology theory in developing an age-appropriate programme to prevent tooth decay. A theory-based approach was adopted for the programme development, and a questionnaire was used to ascertain the knowledge gaps in 52 children aged five to six years in two preschools in an urban town. The results showed that most of the children had no awareness and only a moderate knowledge of proper dental care. Piaget's cognitive development theory was applied in the planning and implementation of the activities in the programme. The developed programme was presented to educational psychologists and dentists, and their feedback was used to refine the programme. The importance of educational psychology theory was illustrated in the development of an age-appropriate preventative programme as well as in using an accessible pedagogical approach. The value of multidisciplinary colloboration was also illustrated.     

Generalized Worry in Patients With Chronic Fatigue Syndrome Following Cognitive Behavioral Therapy: A Prospective Cohort Study in Secondary Care

Research has shown that generalized anxiety disorder is commonly associated with Chronic Fatigue Syndrome (CFS). This prospective cohort study aimed to investigate the prevalence of generalized worry in CFS patients and its relationship with fatigue, anxiety and social functioning, before and after Cognitive Behavioral Therapy (CBT). Our cohort consisted of 470 patients diagnosed with CFS who received CBT at a secondary care, specialist clinic. Patients completed self-report measures investigating levels of generalized worry, fatigue, work and social adjustment, anxiety and depression at baseline (pretreatment), discharge from treatment, 3-month and 6-month follow up (posttreatment). Analysis indicated a high prevalence of generalized worry (72.4%) at assessment. A significant reduction in worry following CBT (M = −3.42, p < .001, 95% CIs: 2.26, 4.57) was observed at discharge, which remained stable at follow-up. Severe baseline worriers had greater overall fatigue score (M = 3.74, p = .026, 95% CIs: .33, 7.15) and worse overall work and social adjustment than mild worriers across time-points (M = 5.42, p = .035 95% CIs: .27, 10.58). Avoidance behavior mediated the association between generalized worry and work and social adjustment (95% bootstrap CIs: 013, .080). The majority of patients with CFS had comorbid generalized worry and severe worriers reported greater fatigue, anxiety, and worse work and social adjustment. This suggests that CFS patients may benefit from targeting generalized worry during CBT.     

一图抵千言：多媒体学习中的自我生成绘图策略

自我生成绘图是指学生使用可视化的学习方法绘制一幅能反映每一段文字中重要观点的图画, 通过图文结合的方式来促进学习的一种策略。综述以往研究发现, 先前研究通过操纵文本、动画等学习材料来考察自我生成绘图在学习中的作用, 发现自我生成绘图的效果并不稳健：一方面它可以通过提高学生的认知和元认知能力、激发积极的情感状态而提高学习效果, 得到了绘图建构生成理论和多媒体学习认知理论的支持; 另一方面也可以通过增加认知负荷而阻碍学习, 得到了认知负荷理论的支持。整体而言, 自我生成绘图策略还是有利于学习的, 已有研究在学习效果上的效应量中值为d_保持 = 0.13, d_理解 = 0.46, d_迁移 = 0.38。未来的研究仍需要关注自我生成绘图策略的材料操纵、效果评定以及潜在变量等等。     

On emotional innumeracy: Predicted and actual affective responses to grand-scale tragedies

The present research demonstrates that people overestimate the intensity of their emotional responses to grand-scale tragedies. Participants predicted that they would feel significantly worse if thousands of people were killed in a disaster than if only a few people were killed, and yet they exhibited an “emotional flatline,” feeling equally sad regardless of the number of people killed. This unforeseeable emotional flatline was demonstrated in response to deaths stemming from human violence and natural disasters, both close to home and far away (including hurricanes in the United States, a forest fire in Spain, and the Iraq War). Participants’ actual emotional responses were calibrated with fatalities only when abstract death tolls were translated into concrete images. We argue that affective forecasts and emotional experiences may arise from separate systems, leading to reliable forecasting errors, as well as influencing subsequent judgments.     

First‐hand sensory experience plays a limited role in children's early understanding of seeing and hearing as sources of knowledge: Evidence from typically hearing and deaf children

One early‐developing component of theory of mind is an understanding of the link between sensory perception and knowledge formation. We know little about the extent to which children's first‐hand sensory experiences drive the development of this understanding, as most tasks capturing this early understanding target vision, with less attention paid to the other senses. In this study, 64 typically hearing children (M_age = 4.0 years) and 21 orally educated deaf children (M_age = 5.44 years) were asked to identify which of two informants knew the identity of a toy animal when each had differing perceptual access to the animal. In the ‘seeing’ condition, one informant saw the animal and the other did not; in the ‘hearing’ condition, one informant heard the animal and the other did not. For both hearing and deaf children, there was no difference between performance on hearing and seeing trials, but deaf children were delayed in both conditions. Further, within both the hearing and deaf groups, older children outperformed younger children on these tasks, indicating that there is a developmental progression. Taken together, the pattern of results suggests that experiences other than first‐hand sensory experiences drive children's developing understanding that sensory perception is associated with knowledge.     

目标定向在自我调节学习中的作用

该研究主要探讨了目标定向与认知策略、失败应对方式之间的关系,以及三者与学业成绩之间的关系,在此基础上对目标定向在自我调节学习中的作用提出了假设：目标定向是自我调节学习的始动机制,它影响着个体在学习中所采用的认知策略,以及在学业失败后所选择的应对方式,而认知策略和失败应对方式则直接对学习效果产生影响。     

证券交易中处置效应的实验研究

该项研究通过控制五只股票、每只股票有18期价格波动的实验来研究中国投资者的投资行为特征。结果发现,被试并没有表现出Bayesian最优行为,处置效应却很明显;被试之间在性别、专业、受教育程度与入市时间上的差异不构成处置效应程度上的差异。但入市资金量在5％的水平上对处置效应程度有显著作用。尽管实验中还发现均值反转信念发生作用的证据,但相对于处置效应而言,解释力度要弱。

The Importance of Theory in Cognitive Behavior Therapy: A Perspective of Contextual Behavioral Science

For the past 30 years, generations of scholars of cognitive behavior therapy (CBT) have expressed concern that clinical practice has abandoned the close links with theory that characterized the earliest days of the field. There is also a widespread assumption that a greater working knowledge of theory will lead to better clinical outcomes, although there is currently very little hard evidence to support this claim. We suggest that the rise of so-called “third generation” models of CBT over the past decade, along with the dissemination of statistical innovations among psychotherapy researchers, have given new life to this old issue. We argue that theory likely does matter to clinical outcomes, and we outline the future research that would be needed to address this conjecture.     

智力风格的三维模型:一种更为综合的认知风格理论

智力风格的三维模型是Li-fang Zhang和Robert J.Sternberg在风格这个研究领域最近提出的一个整合模型.该模型基于Sternberg心理自我管理理论,并结合以往的风格研究,提出了智力风格的概念,把风格分为三种基本类型,而且认为,大部分风格是价值负荷的;是集特质和状态为一体的,但是大部分是可调整的,所以更倾向于状态性;并且具有跨理论的重叠,但也有其独特性.文章对智力风格三维模型的产生背景、理论来源及主要观点进行了介绍,并探讨了该模型的意义.     

The Cognitive Demands of Gait Retraining in Runners: An EEG Study

Abstract

High impact forces during running have been associated with tibial stress injuries. Previous research has demonstrated increasing step rate will decrease impact forces during running. However, no research has determined the cognitive demand of gait retraining. The primary purpose was to determine the cognitive demand and effectiveness of field-based gait retraining. We hypothesized that in-field gait retraining would alter running mechanics without increasing cognitive workload as measured by EEG following learning. Runners with a history of tibial injury completed a gait retraining protocol which included a baseline run, retraining phase, practice phase, and re-assessment following retraining protocol. Results demonstrated an increase in the theta, beta, and gamma power within prefrontal cortex during new learning and corresponding return to baseline following skill acquisition and changes across alpha, beta, gamma, mu, and theta in the motor cortex (p < .05). In the midline superior parietal cortex, spectral power was greater for theta activity during new learning with a corresponding alpha suppression. Overall, the results demonstrated the use of EEG as an effective tool to measure cognitive demand for implicit motor learning and the effectiveness of in-field gait retraining.     

师生认知方式与藏族双语儿童学业成绩关系研究

以藏族双语儿童和任课教师为被试,采用北师大心理系编制的CSFT工具,测查了师生认知方式相互作用对双语儿童学业成绩的影响,研究结果表明：师生认知方式的相互关系对学生的学业成绩有显著的影响,这种影响与学科性质、学习任务有关;双语儿童的认知方式是影响其汉语文、数学成绩的重要因素;不周性别师生认知方式的相互匹配对其汉语文的学习有显著影响;师生认知方式的相互作用对双语儿童学习成绩的影响并非是线性的,师生间性别、认知方式相互作用都是影响双语儿童学业成绩的重要变量。     

具身认知:身体主题在心身关系研究中的回归

上世纪80年代以来,随着经典认知研究的步履维艰,认知研究逐渐显示出具身化的特点。具身认知是第二代认知科学的代表,它强调身体在认知形成中的重要性,认为身体对认知有限制、分配和调节作用,并具有与经典认知不同的运动观。近年来研究者们以实验手段力求为具身认知的存在提供证据,着力考察认知与身体感知运动状态的相互影响。具身认知理论在认知构建、生态效度等方面具有自己的优势,但目前具身认知还是一个新兴的研究领域,有待进一步的深入探讨。     

Identity Processing Style and Depression: The Mediational Role of Experiential Avoidance and Self-Regulation

This study investigated the role experiential avoidance and self-regulation play in mediating relationships between stylistic differences in the way college students engage or attempt to evade the process of constructing a personal sense of identity and depressive symptoms. Two hundred seven 18- to 23-year-old undergraduate students completed measures of identity processing style, self-regulation, experiential avoidance, and depressive symptoms. Consistent with previous research, a diffuse-avoidant identity style was positively associated with depression, which was completely mediated by self-regulation and experiential avoidance. Contrary to prediction, an informational identity style was not directly related with experiential avoidance or depression. However, an informational style indirectly predicted low depressive symptoms via self-regulation. Unexpectedly, when the contribution of self-regulation was controlled, an informational style was positively associated with experiential avoidance, which indirectly predicted high depressive symptoms. The pattern of relationships was not moderated by the sex of the participants. Implications of the results for intervention programs and counseling practices that may enhance the mental health of college students are considered.     

成人依恋与心理理论的关系:认知融合与经验性回避的中介作用

为探究成人依恋、认知融合、经验性回避与心理理论的关系及其作用机制,研究者采用实验法和问卷法对312名成年人进行了测量。研究结果表明：（1）不安全的成人依恋负向预测心理理论;（2）经验性回避在成人依恋与心理理论之间起中介作用;（3）认知融合在成人依恋与心理理论之间不存在中介作用;（4）成人依恋的两种类型（依恋回避、依恋焦虑）呈现出不同的链式中介作用：认知融合与经验性回避在依恋回避与心理理论之间起部分中介作用,而在依恋焦虑与心理理论之间起完全中介作用。研究从心理灵活性的角度考察成人依恋与心理理论的关系及其作用机制,并探究接纳承诺训练在提升社会认知能力上的实践意义。
