绕口令效应对汉语阅读影响的眼动研究

绕口令效应指无论朗读还是默读,绕口令的阅读时间都长于正常句子的阅读时间。本研究采用Eyelink 2000型眼动仪,通过两个实验考察汉语阅读中的绕口令效应及其对知觉广度的影响。实验1结果表明:与阅读非绕口令相比,绕口令的阅读时间和注视次数均显著增加而阅读速度和平均眼跳幅度均显著下降。实验2结果表明:绕口令的知觉广度为注视点右侧1~2个汉字,控制句的知觉广度为注视点右侧2~3个汉字。结果说明汉语中存在绕口令效应,使读者知觉广度变小,阅读效率下降。。     

Comparison of scores for abused and nonabused young adults on the Psychological Trauma and Resources Scale

The Psychological Trauma and Psychological Resources Scale has been developed to identify adolescents and adults who have experienced traumatic events, i.e., physical, sexual, or emotional abuse and neglect. The scale also attempts to identify the presence of compensatory or resource factors such as social support that may serve to ameliorate the effects of traumatic events. 98 college participants who reported a history of abuse were compared with 464 nonabused students on the seven subscales. As predicted, the abused participants reported significantly more incidents of abuse and neglect than the nontraumatized group. In addition, the abused group reported receiving less emotional support, and they were less likely to use positive self-talk as a way to decrease emotional distress. These results provide empirical support for using the Psychological Trauma and Psychological Resources Scale to identify individuals with a history of abuse. Findings underscore the importance of assessing resource variables that may moderate the effects of abuse.     

Children can solve Bayesian problems: the role of representation in mental computation

Can children reason the Bayesian way? We argue that the answer to this question depends on how numbers are represented, because a representation can do part of the computation. We test, for the first time, whether Bayesian reasoning can be elicited in children by means of natural frequencies. We show that when information was presented to fourth, fifth, and sixth graders in terms of probabilities, their ability to estimate the Bayesian posterior probability was zero. Yet when the same information was presented in natural frequencies, Bayesian reasoning showed a steady increase from fourth to sixth grade, reaching an average level of 19, 39, and 53%, respectively, in two studies. Sixth graders' performance with natural frequencies matched the performance of adults with probabilities. But this general increase was accompanied by striking individual differences. More than half of the sixth graders solved most or all problems, whereas one third could not solve a single one. An analysis of the children's responses provides evidence for the use of three non-Bayesian strategies. These follow an overlapping wave model of development and continue to be observed in the minds of adults. More so than adults' probabilistic reasoning, children's reasoning depends on a proper representation of information.     

Incremental planning in sequence production

People produce long sequences such as speech and music with incremental planning: mental preparation of a subset of sequence events. The authors model in music performance the sequence events that can be retrieved and prepared during production. Events are encoded in terms of their serial order and timing relative to other events in a planning increment, a contextually determined distribution of event activations. Planning is facilitated by events' metrical similarity and serial/temporal proximity and by developmental changes in short-term memory. The model's predictions of larger planning increments as production rate decreases and as producers' age-experience increases are confirmed in serial-ordering errors produced by adults and children. Incremental planning is considered as a general retrieval constraint in serially ordered behaviors.     

论理学对中国“画气”说的影响

中国画学中以气论画的传统可以追溯到六朝时期,而真正形成具有丰富理论内涵的画气说则在两宋。画气说的形成具有明显的哲学背景,北宋以来的理学思潮是画气说形成的最直接因素。本文认为,理学对画学理论中气论的影响主要集中在三个方面,一是为画气说提供一个有机论的基础,在气机哲学的影响下,中国画学将表现对象活泼生机作为根本目的,这突出体现在山水画和花鸟画中;二是从审美体验角度,中国画学形成了“以气合气”的独特创作思想;三是在绘画艺术形式上,气势论成为一引人注意的理论,六朝时的气韵生动理论获得了新的发展。     

中小学教师的职业倦怠与工作压力、自尊和控制点的关系研究

本研究旨在探讨中小学教师的职业倦怠与工作压力、自尊和控制点的关系。用教师职业倦怠问卷、工作压力调查表、自尊量表和控制点量表对766名教师进行了问卷调查。结果发现：教师的职业倦怠与工作压力、自尊和控制点之间存在显著的相关关系;教师的工作压力、自尊、控制点分别对职业倦怠的情绪衰竭、非人性化、低成就感具有显著的预测作用。     

中文阅读及发展性阅读障碍眼动研究新进展

中文阅读眼动特征的评估参数主要包括注视点停留位置、眼跳、回视和注视时间等。基于眼动技术,并结合生理技术,研究者已揭示出正常读者中文阅读的多方面特点和规律。但对发展性阅读障碍的眼动研究,国内还没有开展起来。从上述两个角度出发,这里总结了正常读者中文阅读的眼动研究,并探讨了发展性阅读障碍者的眼动特征及机制。     

"Economic man" in cross-cultural perspective: behavioral experiments in 15 small-scale societies

Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model - based on self-interest - fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life.     

The influence of significant others on attitudes, subjective norms and intentions regarding dietary supplement use among adolescent athletes

Dietary supplement use has increased significantly over the past decade. The use of supplements among adolescents seems to be influenced by their beliefs and attitudes. The influence of coaches, parents, and athletic trainers also may be important. The purpose of this study was (1) to determine whether attitudes are a better predictor of adolescents' intentions to use dietary supplements than are subjective norms, and (2) to assess the influence of significant others (coaches, parents, and trainers) on attitudes, subjective norms, and intentions among adolescent athletes. Adolescents (N = 1,626) who were enrolled in grades six through twelve in nine public schools completed a self-report questionnaire that measured attitudes, subjective norms, and intentions regarding dietary supplement use. Results indicated that attitudes were a better predictor of intentions to use dietary supplements than were subjective norms. It was also found that trainers had more influence on the attitudes, subjective norms, and intentions of adolescents regarding supplement use than did parents and coaches. Implications for prevention are addressed.
