The method of vibrotactile mangitude production scaling was used to determine the tactile sensory-perceptual integrity for the dorsum of the tongue and thenar eminence of the right hand for 10 fluent speakers and 10 stutterers. It was discovered that both groups performed the task in a similar manner for the thenar eminence of the hand (a nonoral structure) but in a dissimilar manner for the tongue (an oral structure). From these data, it is suggested that the stutterers may maintain a different internal sensory-perceptual process for the tactile system involved in the speech process. The possibility exists that stuttering, for some, may be an “internal disorder” of the tactile-proprioceptive feedback mechanism that is directly involved in speech production.  相似文献

Adult performance on verbal analogy and classification problems was assessed in terms of the outcomes of process execution. Measures were obtained for the accuracy of stem processing and subsequent alternative processing. The process-outcome measures obtained within each task accounted for overall performance scores and were differentially related to ability. This was shown by ability differences in the models accounting for subjects' overall accuracy and in the correlational patterns. Analogy and classification problem forms differed in the measures most important for predicting individual differences. Specifically, measures of alternative processing were more important in classification than analogy solution and application was shown to be important for analogy solution. In addition, common process-outcome measures showed the highest correlations across problem forms, consistent with the assumption that both induction tasks tap similar psychological processes. The results are discussed with respect to previous studies assessing commonality and individual differences among children in process-outcomes.  相似文献

The present study explored the effect of layoffs on the subsequent productivity of “survivors”. All participants performed a proofreading task either after witnessing the dismissal of a co-worker (Layoff condition) or not (No-Layoff condition). Consistent with equity theory, the quantity of workers' performance was greater in the Layoff than in the No-Layoff condition. A Worker Self-Esteem × Layoff interaction effect revealed that the Layoff effect was entirely attributable to the low, rather than the medium or high, self-esteem participants. Additional analyses revealed that the layoff caused participants to (1) experience increased feelings of remorse and (2) develop more negative attitudes toward their co-worker, both of which are also consistent with equity theory. Practical and theoretical implications are discussed.  相似文献

Although role ambiguity and role conflict have been studied extensively in the organizational sciences, there remain numerous empirical discrepancies among the reported research results. Consequently, disagreement exists as to what can be concluded about the role ambiguity and role conflict research. Coupled with this empirical impasse has been a persistent and relatively singular approach to conceptually studying role ambiguity and role conflict. In response to this empirical and conceptual situation, a meta-analysis and a conceptual reevaluation of the role ambiguity and role conflict research were performed. Using the Hunter, Schmidt, and Jackson (1982, Meta-analysis: Cumulating research findings across studies, Beverly Hills, CA: Sage) meta-analysis procedures, this study analyzed 29 correlates of role ambiguity and role conflict. These correlates include ten organizational context variables, five individual characteristics, ten affective reactions, and four behavioral reactions. Meta-analysis procedures were used to measure the strength and consistency of the relationship found between each of the 29 correlates and role ambiguity and role conflict. Meta-analysis was also used to determine where moderator variables should play a critical part in future role ambiguity and role conflict research. Based on the results of the meta-analysis, several empirical summaries and conclusions are presented. Along with these, several conceptual observations and reconceptualizing suggestions are offered. It is concluded that while a great deal is known about role ambiguity and role conflict in the organizational sciences much remains to be learned.  相似文献

Sex prejudice in children's friendships has frequently been noted. This study examined the role of similarity of attitudes and personal construct ratings in this effect. Subjects were two classes of school children, aged 7–8 and 9–10 years. There were 29 children in each class. Subjects completed an attitude scale, construct rating scale, and sociometric questionnaire. Similarity effects were primarily in the younger children. Boys were more similar to each other in attitudes than were girls, and girls were more similar to each other in construct ratings than were boys (p < .001); there was greater similarity of attitudes and construct ratings in friendship rather than nonfriendship comparison dyads (p < .01). The sociometric data, when compared with sociometric data collected 6 months earlier, showed that these results could not be due to sex differences in the stability of friendships but rather suggested age and sex differences in the informational bases of friendships in middle childhood.  相似文献

Professional exploration modules are offered to the secondary school students attending a Preparatory to Vocational Training (3rd PVT). They are aimed at the academically weak pupils’ remobilization through the development of a training project in vocational education. Based on the model of plural and active socialization (Malrieu, 2003), this article aims to understand the processes of inter-significance between the meaning of school experience, the relation to learning and the relation to the future which underlines the building of the meaning of orientation of middle school students to the PVT program. One hundred and ninety-nine middle school students from 14 to 16 years old who attend the PVT in vocational schools underwent a computerized questionnaire including 96 items. A hierarchical cluster analysis (HCA) differentiates three typical profiles of college students. Though the orientation in the PVT program remains characterized by strong social determinisms (school history and social origin), it seems for a majority of students built on positive representations dependent on the meaning of the previous school experience more than on a projection to the future.  相似文献

Children as pedestrians are one of the most vulnerable groups of road users. Therefore factors associated with risky pedestrian behaviour should be carefully studied. The aim of this article is to clarify how the traffic behaviour of 6th grade students as pedestrians is associated with the behaviour of their traffic companions and prevention activities at school, also taking gender into consideration. The research was conducted based on a randomly-selected sample of 1033 6th-grade students with the mean age of 12.77 ± 0.38 (SD) years. The results showed that compared to girls boys take significantly more risks as pedestrians: they rarely use reflectors during periods of darkness and often cross the road against the red light. The most important role models for adolescents in traffic behaviour are their parents. The role model behaviour with the strongest effect on adolescent high-risk behaviour in traffic is the role model not using crosswalks to cross the street. The results also showed that higher-risk traffic behaviour by adolescent pedestrians is predicted by higher-risk behaviour on the part of their companions (parents, teachers), walking alone on the street, as well as by an adolescent’s lower involvement in the less active prevention activities in the classroom. To improve adolescent pedestrians’ traffic behaviour social environment and school-based factors should be considered more thoroughly in prevention work at school.  相似文献

A single instrument was listed to measure political skills, defined as the understanding of others and the use of that knowledge to influence their actions. It was validated with employees, although political skills were more relevant to managers and, in particular, to school principals. A single study validated the psychometric properties of the instrument with managers showing that the dimensional structure would deploy in 5 factors unlike what is observed among employees, which is deployed in 4 factors. The purpose of this study is to verify whether the tool is reliable and has a distinct structure when employed with a population occupying a management position and more particularly school principals. A total of 304 school principals completed an electronic questionnaire. The results suggest a satisfactory dimensional structure in four factors and good fidelity, which invalidates the use of a separate structure for manager including school principal, as reported by Snell et al. (2013).  相似文献

In this article, the author presents a new methodology for the study of two fundamental components of consciousness, that is thought and language. The fundamental presupposition that forms the basis of this methodology is that thought is not simply a passive "reflection" of an external "reality", but also (and especially) something active, i.e. that the fundamental components of thought are sequences of operations, amongst which the ones of attention play a key role. These sequences of elementary mental operations are called mental categories, and are the meanings of all the words that do not seem to indicate something physical (first of all, all the "grammatical" words, that is conjunctions, prepositions, articles, pronouns, fundamental verbs like "to be", "to have" etc., the main adverbs, and, in the large number of languages that have a more or less rich morphology, all morphemes (the ones which indicate cases, in languages that have cases, the number and the gender of nouns and adjectives, moods and tenses of the verb etc.). The author proposes a list of these elementary mental operations and he shows how it is possible, basing ourselves on them, to identify the meanings of these words, which are indispensable for any linguistic expression. The author also mentions a possible short-term practical application of these theories, i.e. a device in order to improve the quality of machine translation. He also formulates the hypothesis that these theories could allow us to look in a new way at the problem of the (partial) artificial reproduction of the human activity of thought and language.  相似文献

This study investigated the effects of school mobility on reading and math achievement for 1,087 low-income Black children in the Chicago Longitudinal Study. Between kindergarten and seventh grade, 73% of the students changed schools at least once during elementary school and 21% changed schools three or more times. The prospective longitudinal design of the Chicago Longitudinal Study allowed for controlled analyses of both the predictors and the consequences of school mobility. The significant predictors of the number of moves included prior achievement, the number of years of preschool participation in an education intervention program, and parent education. Although the students who changed schools frequently between kindergarten and seventh grade performed approximately one year behind their nonmobile peers on reading and mathematics achievement tests taken at the end of seventh grade, only one half of this difference appears attributable to frequent mobility. The remaining portion is due to the fact that the mobile students were lower achieving even before they started to change schools. The negative consequences of past school mobility are lower for students who moved into better quality schools such as magnets or academic academies. Findings indicate that it is frequent, rather than occasional, mobility that significantly increases the risk of underachievement.  相似文献
