Meta-analysis of the effects of cognitive-behavioral therapy on the core eating disorder maintaining mechanisms: implications for mechanisms of therapeutic change

The original and enhanced cognitive model of eating disorders proposes that cognitive-behavioral therapy (CBT) "works" through modifying dietary restraint and dysfunctional attitudes towards shape and weight. However, evidence supporting the validity of this model is limited. This meta-analysis examined whether CBT can effectively modify these proposed maintaining mechanisms. Randomized controlled trials that compared CBT to control conditions or non-CBT interventions, and reported dietary restraint and shape and weight concern outcomes were searched. Twenty-nine trials were included. CBT was superior to control conditions in reducing shape (g=0.53) and weight (g=0.63) concerns, and dietary restraint (g=0.36). These effects occurred across all diagnoses and treatment formats. Improvements in shape and weight concerns and restraint were also greater in CBT than non-CBT interventions (g's=0.25, 0.24, 0.31, respectively) at post-treatment and follow-up. The magnitude of improvement in binge/purge symptoms was related to the magnitude of improvement in these maintaining mechanisms. Findings demonstrate that CBT has a specific effect in targeting the eating disorder maintaining mechanisms, and offers support to the underlying cognitive model. If changes in these variables during treatment are shown to be causal mechanisms, then these findings show that CBT, relative to non-CBT interventions, is better able to modify these mechanisms.

基于认知设计系统的几何类比推理测验的编制及认知模型分析

认知诊断是一种新的测量范式。本研究首先根据Mulholland,Pellegrino＆Glaser和Whitely＆Schneider关于类比推理的研究结果,采用认知设计系统编制了几何类比推理测试题,并对所编制的测试题的质量进行验证,然后采用口语报告法分析解决几何类比推理所涉及的认知模型,结果表明：1）编制的几何类比推理测试题的质量比较好;2）学生解决类比推理所涉及的认知属性主要为置换、翻转、旋转、数量、大小、颜色与条纹和形状。     

Dreaming and hallucinations - continuity or discontinuity? Perspectives from dementia with Lewy bodies

Comparing the phenomenology, neurochemical pathology, and psychopharmacology of hallucinations and dreaming is limited by the available data. Evidence to date reveals no simple correspondence between the two states. Differences in the phenomenology of visual hallucinations and the visual component of dreams may reflect variations in visual context acting on the same underlying mechanism – the minimal visual input during dreaming contrasts with the more substantial perceived context in hallucinations. Variations in cholinergic, dopaminergic and serotonergic neurotransmitter function during sleep and during hallucinations in Lewy body dementias, together with relevant drug effects suggest that, on the whole, different, potentially opposite, changes characterise the two states. A similar analysis of other psychotic features in Lewy body dementia and other disorders suggests that, in contrast to hallucinations, there may be more convincing parallels between dreaming and delusional states.     

La valorisation professionnelle des caractéristiques de personnalité masculines,féminines et androgynes

This article examines the professional valorisation of gender-typed traits. In the study, participants should assess masculine, feminine and androgynous profiles in a set of professional contexts obtained by the crossing of social status (high versus low), gender (masculine versus feminine) and sector (production versus maintenance) of occupations. Consistent with a gender- typed trait matching model, the results showed that masculine profiles were the most valued ones in the most masculine occupations, feminine profiles were mostly valued in the most feminine occupations while androgynous profiles were the most valued in gender ambiguous occupations. Of particular interest was the fact that the perception of occupations’ gender was a function of the interaction between the gender and the sector of occupations (i.e.: the most masculine occupations were those that were stereotypically masculine and belonging to the production sector; the most feminine were those that were stereotypically feminine and belonging to the maintenance sector; the stereotypically masculine and maintenance occupations as the stereotypically feminine and production occupations were perceived as less gender typed).     

The emotional geographies of education: Beginning a conversation

While emotional geography is a burgeoning field of inquiry, to our knowledge no emotional geographies of education exist. Educational research on space and place largely ignores emotionality. In this special issue we begin to rectify this situation through the development of what we call socio-cultural-spatial analyses of education and emotion.     

积极心理学视野下的工作压力

工作压力是职业健康心理学研究的重要领域。随着经济发展,工作压力问题日益突出,它降低了生产率,使员工的健康受损,增加了成本消耗。但是以往的研究主要关注压力的消极面,干预方法也是以预防和治疗为主。然而积极心理学运动的兴起改变了传统的工作压力研究方法,提出积极压力的概念,倡导以健康、整合的方式建立一个完整的工作压力模型。并提出在预防和治疗消极压力的同时,也要重视激发积极压力。     

Distinctions between hedonic and eudaimonic well-being: Results from a day reconstruction study among Norwegian jobholders

The study suggests that hedonic and eudaimonic well-being can be studied by theoretical and empirical analysis of subjective feelings. In this approach, pleasure is the hallmark of hedonism, and engagement serves as the core feeling of eudaimonia. The Day Reconstruction Method was used to investigate the assumption that overall life satisfaction predicts hedonic feelings but not eudaimonic feelings during a workday. Perceived job control was hypothesized to predict eudaimonic feelings but not hedonic feelings. Questionnaire data from 120 Norwegian jobholders were analyzed, providing support for the hypothesis. Moreover, pleasure was found to be relatively unrelated to engagement, and perceived control was basically unrelated to life satisfaction. The results are discussed against the background that hedonism and eudaimonia are two independent parts of a multidimensional concept of well-being.     

Applying an exemplar model to the artificial-grammar task: Inferring grammaticality from similarity

We present three artificial-grammar experiments. The first used position constraints, and the second used sequential constraints. The third varied both the amount of training and the degree of sequential constraint. Increasing both the amount of training and the redundancy of the grammar benefited participants' ability to infer grammatical status; nevertheless, they were unable to describe the grammar. We applied a multitrace model of memory to the task. The model used a global measure of similarity to assess the grammatical status of the probe and captured performance both in our experiments and in three classic studies from the literature. The model shows that retrieval is sensitive to structure in memory, even when individual exemplars are encoded sparsely. The work ties an understanding of performance in the artificial-grammar task to the principles used to understand performance in episodic-memory tasks.
