知识表征的新观点--知觉符号理论

在认知科学中一个经典的争论是知识在人的头脑中是如何表征的。其中占主流的理论一直是命题符号理论,而最近Barsalou又提出了一种新的观点——知觉符号理论。本文对这一新理论做了介绍,阐述了它的主要特征,比较了它与命题符号理论的差异,并提供了现今对这一理论的实验证实。希望借此能启发国内的研究者也来关注和研究这一理论。     

我国3～6岁儿童个性类型及发展特点的研究

该文在以往中国儿童个性结构研究基础上,以问卷调查（n=927）方式,将层次聚类和迭代聚类两种方法结合起来,同时采用理论分析等方法最终确定我国3～6岁儿童的个性类型包括认可型、矛盾型、拒绝型及中间型四类。其中认可型属于积极个性类型,矛盾型和拒绝型属于消极个性类型。研究表明,中班到大班阶段是幼儿个性发展相对重要的时期。男女幼儿在多个个性维度及大部分具体特质方面存在着明显的性别差异。     

2岁幼儿移情反应的特点:与自发帮助、气质、亲子互动的关系

1引言 在儿童早期的社会发展中,社会情绪及其相应的社会行为发展最为关键。由社会动因驱使的人际互动行为,如爱抚、安全、舒适等需要的满足将导致社会情绪状态的重组和发展。在诸多的社会情绪中,移情能力的发展对于幼儿来说尤为重要。移情是对另一个人产生同感的情感反应（Hoffman,2003）,它是一种复杂的情绪沟通能力,是在条件反射基础上,在人际互动过程中,通过模仿、强化逐渐形成的。     

未来时间洞察力的目标作用

未来时间洞察力是个体对未来时间的认知、体验和行动（或行动倾向）的一种人格特质,其目标不仅架起了现在与未来的桥梁,也影响个体的认知与行为,并且不同目标还具有不同的动力作用。但个体如何建构未来目标、确立优势目标等,需做进一步研究。

The Negative Physical Self Scale: Initial development and validation in samples of Chinese adolescents and young adults

This research presents four studies on the initial development and validation of the 48-item Negative Physical Self Scale (NPS), a multidimensional measure of body image concerns for use with Chinese samples. In Study 1 (N = 1095), exploratory factor analyses identified five dimensions underlying the NPS (General Appearance, Facial Appearance, Shortness, Fatness, Thinness). In Study 2 (N = 1057), confirmatory factor analyses replicated this factor structure. In Studies 3 and 4, the validity of all NPS dimensions except Thinness Concern was supported via their patterns of relation with both objective physical characteristics/behaviors and other self-report measures of body image and general self worth. Because Chinese adolescents and young adults expressed relatively more concerns about General Appearance, Shortness, and Facial Appearance than about Fatness, the NPS may have greater utility for assessing body image disturbances in China than existing measures that focus exclusively on general body satisfaction and body size/weight.     

Verbal and cognitive distractors in driving performance while using hands-free phones

This study investigated the effect of different types of distractions related to use of a hands-free phone on driving performance. The study used three types of verbal distractors: casual conversation, simple arithmetic number guessing, and number adding, in the phone conversation. 12 adults were instructed to follow a lead vehicle on a closed-course highway in a fixed-based driving simulator. The results showed that use of a hands-free cellular phone involving verbal and cognitive distractions impaired driving performance and skill. Types of distraction produced significantly different effects on several dependent variables: the driving speed, headway (distance between the lead car and the manipulated car), brake reaction time, and number of collisions with the lead car. In general, the higher the cognitive load involved in the dialogue, the worse the driving performance.     

"中小学生心理健康"公众观的调查和分析

本研究调查分析了家长、教师对中小学生心理健康判断标准的认识.因素分析表明,家长主要强调四个因素"精神和神经病症"、"良好品行"、"健康人格"和"循环性";教师则强调五个因素"精神分裂症状"、"神经质"、"好学生标准"、"不良人格"和"不良品行".公众对于情、意、个性及社会适应等同心理健康的关系认识较为清楚,但对认知、品行及体征与之的关系认识则片面和模糊."好学生标准"对判断有重要影响.     

Attitudes toward genetic counseling and prenatal diagnosis among a group of individuals with physical disabilities

Few studies have been published on the attitudes of people with physical disabilities toward genetic counseling and prenatal diagnosis. Articles in the lay press and social science literature on this topic, mainly written by disability rights activists and advocates, imply opposition to prenatal diagnosis and the field of clinical genetics by the physically disabled population. In this study, 15 adults with physical disabilities were interviewed regarding their attitudes toward genetic counseling and prenatal diagnosis. Genetic counseling and prenatal diagnosis were generally viewed favorably by this sample of the disability community. Only a small percentage of the sample perceived genetics to be eugenic. Implications for genetic counseling and future research are discussed.     

Validation of a single-item measure of usual physical activity

The purpose of this study was to assess the reliability and validity of a single-item measure of Usual Physical Activity and to assess its usefulness as a physical activity tool for perimenopausal women. 188 perimenopausal women participated (age: M = 47 yr., SD = 3; range = 40-55). Data were collected using the Women's Health Assessment Scale, the Physical Activity Questionnaire, the Perimenopause-related Quality of Life Scale, a health history and demographic questionnaire, and the rater. Scores were stable over a 2-wk. interval. Convergent validity was supported by a correlation of .66 between ratings on Usual Physical Activity and the Physical Activity Questionnaire. Concurrent validity was supported by the association of the rating of Usual Physical Activity with three parameters of Body Mass Index, psychosomatic symptoms, and perimenopause related quality of life, known to be associated with physical activity. Highly active women had a lower Body Mass Index than less active and inactive women. Active women tended to report fewer and less distressing psychosomatic symptoms and better quality of life. These findings support the use of rating of Usual Physical Activity to classify perimenopausal women into categories of physical activity.
