I can’t stop looking at them: Interactive effects of body mass index and weight dissatisfaction on attention towards body shape photographs

Although attentional biases toward body-related information contribute to the etiology and maintenance of body dissatisfaction (BD) and eating disorders (EDs), attentional disengagement in women with BD and EDs is not clear. The present study investigated the association between weight dissatisfaction and attentional disengagement from body-related pictures and the possible moderating effect of body mass index (BMI) on this relation. Two hundred and four undergraduate women engaged in an experiment using a pictorial spatial cueing paradigm including fat/thin bodies and neutral household photos. Partial correlations and simple slopes regression analyses were conducted with attentional disengagement index scores of each category of cues. Findings suggested that independent of BMI, weight dissatisfaction was directly associated with attentional disengagement from both fat and thin pictures. In addition, among women with low and medium BMIs, the more they were dissatisfied with their bodyweight, the more difficulty they had disengaging their attention from fat body pictures.     

No Time of Day Modulation or Time Stamp on Multiple Memory Tasks in Rats

Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning.     

创造性的生理研究新进展

创造性的生理基础很复杂。关于创造性生理基础的研究集中在大脑皮质激活与脑半球不对称两个方面。研究发现,大脑皮质激活状态对创造性有影响,低水平的皮质激活,特别是低水平的前额叶激活,较有利于创造性．研究还发现,创造性和左右半球不对称活动有关,处于创造状态时,右半球相对要比左半球激活程度更高。     

新古三论略议

三论宗是以龙树的《中论》、《十二门论》和提婆的《百论》为所依,宣扬空、无相、八不中道等义理的宗派。由姚秦时罗什传来的三论学,谓古三论;而由僧朗、僧诠、吉藏所传的三论学,称为新三论。新、古之分,不仅因其在传承和时间上,就是在产生的背景、思想和影响上均有差别。     

Cloninger's Temperament and Character Inventory Correlates with Personality Characteristics of Organ Donation Advocates

Temperament and Character Inventory (TCI) and background questionnaire data were collected from a sample of men and women organ donation advocates (N = 362) as part of a national study to investigate their personality characteristics, temperaments, and attitudes about organ donation advocacy. Goals included identifying unique traits for advocates, and response consistency between the TCI and questionnaire. The TCI results included high scores on Cooperativeness and Self-Directedness, and low on Harm Avoidance dimensions. The questionnaire results indicated that most advocates were White, married, college-educated females, who typically spent less than 2 hr with potential donor families, were satisfied with life and job, and believed they would be in a donation position 2 years from the time surveyed. TCI and questionnaire measures were correlated for Self-Transcendence and Spirituality, Helpfulness and Job Satisfaction, and Compassion and Identification variables.     

儿童绘画表现性发展的研究进展

自Goodman提出美的3个性质(表现性、充实性、结构性)以来,发展心理学家们兴起了根据儿童绘画的表现性来探讨儿童认知发展的热潮。该回顾了儿童绘画表现性的发展研究进展,以及对儿童绘画认知的模型探讨。     

婴儿物理因果感知能力的发展

继Michotte(1963)用两个发生碰撞的小球对成人的物理因果理解进行研究以来,许多研究者使用该碰撞情境对婴儿的物理因果感知进行了一系列的研究,并得出了许多颇有争议的结论。本文结合近几年国外对婴儿物理因果感知能力的相关研究,阐述了婴儿感知简单物理情境中的因果关系能力的发展,评价了用来解释婴儿物理因果感知的模块理论与信息加工理论,以期对婴儿期的物理因果感知有一较全面的了解。     

关于克隆人试验与伦理学的三原则

由于克隆人试验的对象是人的活细胞,不是人的胚胎;并且由于人只能有限地决定自己的未来,根本无法决定自己的出生;同时由于基因诊断和修复有助于新生儿的健康,因而克隆人试验既不会伤害任何人的生命体,也不会侵犯任何可能出现的克隆人的自主权和平等权,进而不会违反伦理学的三原则。     

中文读写能力及其相关因素的结构模型

运用问卷调查法考查了中文儿童读写能力及其相关因素之间的关系.通过验证性因素分析对量表的信度和效度指标进行了分析,发现量表具有较好的项目信度和结构效度.结构模型分析发现阅读听写能力影响书面语意义理解和书写技能,而书面语意义理解和书写技能对书面表达有显著影响.家庭阅读背景影响儿童的口语能力和阅读听写能力,口语能力影响意义理解和阅读听写能力,基本知觉加工影响口语能力和阅读听写,动作技能影响书写技能.上述结果表明中文字词识别、书写技能和意义理解水平都影响书面表达,即段落产生能力.而口语能力、家庭阅读背景、基本知觉加工和动作技能分别对读写能力的不同侧面产生影响.本研究还分析了模型的年龄和性别特点.
