聋生汉字识别的同音判断与启动效应实验研究

本研究采用暂同形似、音同形异、音异形似和无关字四类汉字字组为实验材料．每类字组都按汉字使用频率分为低频字、中频字、高频字三种．对使用手语聋生和使用口语聋生进行了同音判断和启动效应实验,旨在探究聋生在汉字识别过程中语音编码所起的作用。实验结果表明,在聋生汉字识别中,字形的知觉加工对提取语音具有非常重要的作用,但语音的提取对聋生来说非常困难。不同字频对不同字组的同音判断成绩的影响不同,表明聋生对不同汉字的语音意识不同。聋生在汉字识别中存在语音混淆和字形混淆的现象,说明语音编码和字形编码在汉字识别过程中都起了重要的作用。字频对聋生汉字识别的影响也不同,同频字产生语音特征的影响;低频字产生字形特征的影响;而中频字都不产生语音特征和字形特征的影响。     

Effects of Media and Collaborative Distributed Information on Concept-Learning

1IntroductionSuchman,an anthropologist,argued that actionswere always situated in particular social and physi-cal circumstances[1].In this view actions emergefrom moment-by-moment interactions between ac-tors,and between actors and their environments.The social and environmental aspects of cognitionhave been stressed in Hutchins′work[2].He hadstudied relatively structured decision environments,for example ship navigation and aeroplane piloting.His conclusions are that cognition in such situa…     

Continual training of attentional bias in social anxiety

Using the dot-probe paradigm, it has been shown that high social anxiety is associated with an attentional bias toward negative information. In the present study, individuals with high social anxiety were divided into two groups randomly. One group was the attentional bias training group (Group T), and the other was the control group (Group C). For Group T, 7 days' continuous training of attentional bias was conducted using the dot-probe paradigm to make socially anxious individuals focus more on positive face pictures. The results showed that the training was effective in changing attentional bias in Group T. Scores of the Social Interaction Anxiety Scale (SIAS) in Group T were reduced compared to Group C, while the scores of Social Phobia Scale (SPS) and scores of Negative Evaluation Scale (FNE) showed no difference between the two groups, which suggested a limited reduction of social anxiety.     

Parenting stress, perceived parenting behaviors, and adolescent self-concept in European American families

This study assesses whether the stresses associated with parenting a child are indirectly related to adolescent self-concept through parenting behaviors. We examined longitudinal associations among mothers' and fathers' parenting stress at age 10, children's perceptions of parenting at age 10, and adolescents' self-concept at age 14 in 120 European American families. Mothers' and fathers' parenting stress was related to children's perceptions of acceptance and psychologically controlling behavior, and psychologically controlling behavior (and lax control for fathers) was related to adolescent self-concept. We further examined which domains of parenting stress and perceived parenting behaviors were associated with adolescents' scholastic competence, social acceptance, physical appearance, and behavioral conduct. Parenting stress was related to specific parenting behaviors, which were, in turn, related to specific domains of self-concept in adolescence. Parenting stress appears to exert its effects on early adolescent self-concept indirectly through perceived parenting behavior.     

Rehearsal in immediate serial recall

We report for the first time overt rehearsal data in immediate serial recall (ISR) undertaken at three presentation rates (1, 2.5, and 5 sec/word). Two groups of participants saw lists of six words for ISR and were required either to engage in overt rehearsal or to remain silent after reading aloud the word list during its presentation. Typical ISR serial position effects were obtained for both groups, and recall increased with slower rates. When participants rehearsed, they tended to do so in a cumulative forward order up to Serial Position 4, after which the amount of rehearsal decreased substantially. There were similarities between rehearsal and recall data: Both broke down toward the end of longer sequences, and there were strong positive correlations between the maximum sequence of participants' rehearsals and their ISR performance. We interpret these data as suggesting that similar mechanisms underpin both rehearsal and recall in ISR.

Mainland Chinese and Canadian adolescents’ judgments and reasoning about the fairness of democratic and other forms of government

This study examined the judgments and reasoning of adolescents (ages 12–19 years) from three sites in urban and rural China (n = 270) and in an urban Canadian comparison sample (n = 72), about the fairness of various forms of democratic and non-democratic government. Adolescents from both China and Canada preferred democratic forms of government, such as representative or direct democracy, to non-democratic systems, such as a meritocracy and an oligarchy of the wealthy, at all ages. Adolescents appealed to fundamental democratic principles, such as representation, voice, and majority rule, to justify their judgments. Similar age-related patterns in judgments and reasoning were found across cultures and across diverse settings within China.     

Confucian Democracy as Pragmatic Experiment: Uniting Love of Learning and Love of Antiquity

This paper argues for the pragmatic construction of Confucian democracy by showing that Chinese philosophers who wish to see Confucianism flourish again as a positive dimension of Chinese civilization need to approach it pragmatically and democratically, otherwise their love of the past is at the expense of something else Confucius held in equal esteem, love of learning. Chinese philosophers who desire democracy for China would do well to learn from the earlier failures of the iconoclastic Westernizers, and realize that a Chinese democracy cannot come about by ignoring or dismissing such an important part of China's history, its Confucian tradition. The best chances for democracy in China lie in transforming that tradition without destroying it. Eagerness to learn from others must be united with a proper appreciation of one's own past to nurture democracy as a way of life.     

Autonomy,culture, and well-being: The benefits of inclusive autonomy

In an attempt to understand cultural variation in motivation, we distinguished between the type of motivation (ranging from controlled to autonomous, as conventionally measured) and the subject of motivation (“I” vs. “my family and I”), creating measures of individual and inclusive academic motivation. Support was found for three hypotheses. First, Chinese Canadian and Singaporean students felt less relative autonomy than European Canadian students, on both the inclusive and individual measures. Second, individual relative autonomy was associated with psychological well-being (WB) for European Canadians and Chinese Canadians (Study 1), and Singaporeans (Study 2). Third, inclusive relative autonomy was associated with psychological well-being for Chinese Canadians and Singaporeans, but not European Canadians. Exploratory analyses are also presented, and implications for the theory and measurement of autonomy are discussed.     

Detection theory analysis of scaling and discrimination tasks: responses to noxious thermal stimuli

This study's main purpose was to examine the sensitivity estimates obtained from scaling and discrimination approaches for nociception assessment in healthy individuals. This investigation may inform future applications in diagnostic procedures for painful conditions. Models of psychophysical judgment based on those of Durlach and Braida (1969), Laming (1984), and Irwin and Whitehead (1991) were used as the common analytical framework. Noxious thermal contact stimuli were used. The results show that the scaling approach produced lower detection theory sensitivity estimates than did the discrimination approach. The additional judgment variance in scaling tasks could explain this lowered sensitivity. The relative judgmental variance value of 2.18 obtained in this study is lower than variance values found i n previous investigations. This discrepancy i s probably due to the relatively smaller stimulus range employed in this study. The authors propose that the theoretical framework used in this study may be used in future studies to investigate the different dimensions of pain perception.
