Adolescents are proportionately more frequently involved in traffic accidents than are other age groups. A strategy for promoting road safety is to change the attitudes likely to influence driving behavior. However, the lack of valid and reliable instruments to measure risk-taking attitudes makes it difficult to evaluate the effects of measures aimed at changing attitudes among young drivers and their passengers. The present study tested the psychometric qualities of a scale intended to measure adolescents' risk-taking attitudes to driving. The results are based on a self-completion questionnaire survey carried out among 3,942 adolescents and young adults, aged 16-23 years, in Norway in 1998/1999. Using both exploratory and confirmatory factor analyses, 11 dimensions of risk-taking attitudes were identified. Parametric as well as nonparametric methods were applied to test the homogeneity of items within each attitude dimension. The reliability and validity of the dimensions were satisfactory. The attitude dimensions were significantly correlated with self-reported driving behavior, as well as accident frequency. The application of the new measurement instrument in studies aimed at evaluating safety campaigns is discussed.  相似文献

The goal of this study was to test the diathesis–stress component of Linville's and Morgan and Janoff-Bulman's models of the relationship between self-complexity and depressive symptoms in a sample of third and seventh grade children (P. W. Linville, 1985, 1987; H. J. Morgan & Janoff-Bulman, 1994). The procedure involved an initial assessment of self-complexity and depressive symptoms. The procedure also involved a follow-up assessment, 10 weeks later, in which depressive symptoms and the occurrence of negative events were assessed. Contrary to hypotheses, neither high levels of total nor positive self-complexity served as a buffer against the onset of depressive symptoms following the occurrence of negative events. In line with hypotheses, however, high levels of negative self-complexity interacted with the occurrence of negative events to predict increases in depressive symptoms in seventh but not third grade children.  相似文献

Recent models of lexical processing suggest that written spelling partly depends upon the semantic system. According to these models, a deterioration in word meanings would necessarily lead to a spelling impairment, especially for low-frequency and orthographically irregular words. We report a case study of a patient (MK) with semantic dementia who presents impairments in knowledge of word meanings and surface dysgraphia. By specifically identifying concepts that are still known or that are partially or completely deteriorated, we show that the patient's spelling deficit is highly correlated with word comprehension. These data confirm that surface dysgraphia is directly linked to the breakdown in semantic memory.  相似文献

Involvement of short-term memory in complex mental calculation   总被引:6,自引:0,他引:6  
The aim of this study was to examine the involvement of the short-term memory system in complex mental addition by manipulating the phonological and visual similarity of two numbers to be added. The phonological similarity of the problems appeared to have a major effect on both speed and accuracy. However, the manipulation of visual similarity failed to have any measurable impact. This suggests that the phonological loop, rather than the visual-spatial sketch pad, would be used preferably for temporary storage of addends. An interpretation of these results in terms of the nature of the internal code underlying this task is discussed.  相似文献

Background: Recent research on the influence of presentation format on the effectiveness of multimedia instructions has yielded some interesting results. According to cognitive load theory (Sweller, Van Merriënboer, & Paas, 1998) and Mayer's theory of multimedia learning (Mayer, 2001), replacing visual text with spoken text (the modality effect) and adding visual cues relating elements of a picture to the text (the cueing effect) both increase the effectiveness of multimedia instructions in terms of better learning results or less mental effort spent. Aims: The aim of this study was to test the generalisability of the modality and cueing effect in a classroom setting. Sample: The participants were 111 second‐year students from the Department of Education at the University of Gent in Belgium (age between 19 and 25 years). Method: The participants studied a web‐based multimedia lesson on instructional design for about one hour. Afterwards they completed a retention and a transfer test. During both the instruction and the tests, self‐report measures of mental effort were administered. Results: Adding visual cues to the pictures resulted in higher retention scores, while replacing visual text with spoken text resulted in lower retention and transfer scores. Conclusions: Only a weak cueing effect and even a reverse modality effect have been found, indicating that both effects do not easily generalise to non‐laboratory settings. A possible explanation for the reversed modality effect is that the multimedia instructions in this study were learner‐paced, as opposed to the system‐paced instructions used in earlier research.  相似文献

The notion of “dangerousness” takes an increasing importance currently at the level of the Justice, magistrates and supervisors of jail being brought thus to assess it frequently. A question arises then, that of the significance assigned by these professionals to dangerousness. Results of the interviews achieved close to these two groups as well as with citizens reveal homogeneous representations as for the dangerous individual but greatly heterogeneous representations with respect to the dangerous situations. While confirming the existence of several dangerousness (social, penal and prison), these results also show that all dangerousness assessment can be satisfactory on condition that it is done in an both clinical and social approach.  相似文献

Using a historical and biographical perspective, this paper examines the structural elements and cultural signs of contemporary social events and problems in Turkey in order to understand their basic features. Hermeneutics is used in order to understand contemporary Turkey by way of its historical background and prominent biographies. Two basic epic texts were interpreted using Gadamarian hermeneutics with the help of key concepts such as gaza1 and gaza cult. Semiotics is used to examine key concepts as binary opposites. Dialectics is used to understand these concepts as the unity of binary opposites coexisting at the same time and place. It is concluded that the contemporary cultural values and biographies explored are linked to their historical past and Islam seems to be more influential on hybrid identities than on ethnic status.  相似文献

Quality is a major current needs and requirements for any university system. The funding that universities receive a relevant influence on the scientific productivity of these. Thus the main objective of this study is to classify the Spanish regions in terms of scientific productivity and economic efficiency of their universities. It followed the same procedure used to prepare the 2009 ranking of research productivity in Spanish universities. The results show that there are differences in the classifications made on the basis of productivity and efficiency in the investigation. The more efficient Spanish regions in managing its resources to obtain research results are Catalonia, Asturias, Aragon, and Cantabria. From the results, each region can compare their situation with the rest and analyze strengths and weaknesses in research in terms of resources.  相似文献

Theorists disagree about how to define the concept of empowerment. This disagreement extends to discussions of adolescent girls’ sexual empowerment. Feminists struggle with whether sexual empowerment should be conceptualized as a subjective internal feeling of power and agency or an objective measure of power and control. Defining sexual empowerment as a subjective state may mistakenly equate feelings of agency with cultural and institutional power. Yet, a subjective definition of sexual empowerment is advantageous in that it validates girls’ own experiences and perceptions. This commentary argues that sexual empowerment might best be conceptualized as a continuous and multidimensional construct. This would allow for the recognition of sexual empowerment as a developmental process, and it would allow for the acknowledgement of ambivalent empowerment.  相似文献

Mimicry has benefits for people in social interactions. However, evidence regarding the consequences of mimicry is incomplete. First, research on mimicry has particularly focused on effects of being mimicked. Secondly, on the side of the mimicker evidence is correlational or lacks real interaction data. The present study investigated effects for mimickers and mimickees in face‐to‐face interaction. Feelings towards the immediate interaction partner and the interaction in which mimicry takes place were measured after an interaction between two participants in which mimicry did or did not occur. Results revealed that mimickers and mimickees became more affectively attuned to each other due to bidirectional influences of mimicry. Additionally, both mimickers and mimickees reported more feelings of having bonded with each other and rated the interaction as smoother.  相似文献
