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 medial temporal lobe has been implicated in studies of episodic memory tasks involving spatio-temporal context and object-location conjunctions. We have previously demonstrated that an increased level of practice in a free-recall task parallels a decrease in the functional activity of several brain regions, including the medial temporal lobe, the prefrontal, the anterior cingulate, the anterior insular, and the posterior parietal cortices, that in concert demonstrate a move from elaborate controlled processing towards a higher degree of automaticity. Here we report data from two experiments that extend these initial observations. We used a similar experimental approach but probed for effects of retrieval paradigms and stimulus material. In the first experiment we investigated practice related changes during recognition of object-location conjunctions and in the second during free-recall of pseudo-words. Learning in a neural network is a dynamic consequence of information processing and network plasticity. The present and previous PET results indicate that practice can induce a learning related functional restructuring of information processing. Different adaptive processes likely subserve the functional re-organisation observed. These may in part be related to different demands for attentional and working memory processing. It appears that the role(s) of the prefrontal cortex and the medial temporal lobe in memory retrieval are complex, perhaps reflecting several different interacting processes or cognitive components. We suggest that an integrative interactive perspective on the role of the prefrontal and medial temporal lobe is necessary for an understanding of the processing significance of these regions in learning and memory. It appears necessary to develop elaborated and explicit computational models for prefrontal and medial temporal functions in order to derive detailed empirical predictions, and in combination with an efficient use and development of functional neuroimaging approaches, to further the understanding of the processing significance of these regions in memory.  相似文献

Persons with Asperger Syndrome often seem to have difficulty performing everyday occupations. This study aimed to describe occupational therapists' experience concerning abilities to occupational performance among adults with Asperger Syndrome. Data were collected in interviews with eight occupational therapists and analyzed using a qualitative method. Results showed that clients with Asperger Syndrome often possess abilities but seem to have difficulties knowing when, where, and how they should use them. The ability to adapt behavior in accordance with cues from the environment was identified as the core category. Environment plays a major role in how these persons interact in different situations.  相似文献

We examined whether the text understanding of students holding naïve and sophisticated epistemological beliefs was differentially affected by text format, also controlling for effects of gender, word decoding, and prior knowledge on understanding. The participants were 39 Norwegian first-year teacher students, and the topic of reading was attention-deficit hyperactivity disorder (ADHD). It was found that only readers holding sophisticated epistemological beliefs displayed adequate understanding when reading multiple, partly conflicting, texts about ADHD, whereas students holding naïve epistemological beliefs gained better understanding when reading a single textbook-like source with identical content. This finding, however, depended on the level of understanding being measured by the criterial task, with only the task measuring deeper situational text understanding showing an interaction between epistemological beliefs and text format. This study provides evidence that not only knowledge itself, but also personal beliefs about knowledge, may enhance or constrain deeper understanding of multiple texts.  相似文献

The following arguments are constructed around the encounter of embodied experiences and societal discourses. On the basis of an ethnographic study of 34 Danish consumers, we present different consumers' strategies in relation to their perception of healthy food and management of food‐related health risk. Drawing on a subsample representing particular subject positions in relation to healthy eating, we argue for an increased role of embodiment in consumers' risk handling. The study shows that because of the overload of information, consumers increasingly turn to personal experiences and bodily feelings as the instrument and strategy for evaluating possible health risk and benefit. Furthermore, the study shows how these evaluations are related to broader political and socio‐economic issues as well as closely intertwined with notion of trust and mistrust. Through embodied feelings, consumers navigate and negotiate their position in relation to social discourses of health and risk. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Aim: To explore the process of ending in psychotherapy, in particular how clients and therapists draw on their notions of client improvements and prepare for the upcoming end. Data: The data comes from an intensive process‐outcome study at the University of Oslo, Norway. The study includes audio‐recording from all sessions and separate post‐therapy interviews with clients and therapists. Twelve psychotherapy dyads were selected because they had reached a ‘good enough’ ending. Therapy duration ranged from 7–43 months. The number of sessions ranged from 10–67. Method and analysis: A hermeneutical‐phenomenological approach analysed and combined the observational and reflexive data. The analysis was carried out using a method for systematic text condensation and through reflexive dialogues with the material and between the researchers. Findings and discussion: The language of improvement towards the end of treatment seemed packed with metaphors conveying growth in both affective and relational management. Metaphors based on travel (how they have moved); cleaning (how they have cleaned up and sorted out things); sensing (how the clients have grown stronger, got their heads above water and see things differently); and the clients’ feeling of having received something (gifts or tools) are widely used. Such metaphors are created in the interaction with a mutual sensitivity to their capacity to confirm and regulate affect towards the end. In this sense, the metaphors celebrate accomplishments in a way that exceeds therapy, and the client can keep them to use afterwards.  相似文献

In times of crisis such as the Reformation, the quest for the true Church comes into focus. In Luther's most important contribution to this question, Von den Konziliis und Kirchen (1539), he rejects the idea that the history of Fathers and Councils could be the solution, though the Councils are significant as defence of the biblical faith. Instead, Luther identifies the true Church as the place where the Spirit sanctifies believers through the word of God, which is the most important nota ecclesiae. The presence of the divine as fact and goal is thus what characterises the true Church.  相似文献

This simulation study investigates the performance of three test statistics, T1, T2, and T3, used to evaluate structural equation model fit under non normal data conditions. T1 is the well-known mean-adjusted statistic of Satorra and Bentler. T2 is the mean-and-variance adjusted statistic of Sattertwaithe type where the degrees of freedom is manipulated. T3 is a recently proposed version of T2 that does not manipulate degrees of freedom. Discrepancies between these statistics and their nominal chi-square distribution in terms of errors of Type I and Type II are investigated. All statistics are shown to be sensitive to increasing kurtosis in the data, with Type I error rates often far off the nominal level. Under excess kurtosis true models are generally over-rejected by T1 and under-rejected by T2 and T3, which have similar performance in all conditions. Under misspecification there is a loss of power with increasing kurtosis, especially for T2 and T3. The coefficient of variation of the nonzero eigenvalues of a certain matrix is shown to be a reliable indicator for the adequacy of these statistics.  相似文献

Given the pioneering role of Scandinavian research in the field of bullying at work, it is surprising that Danish researchers have largely ignored this problem. Presumably, this has led to a situation where many Danish company managers and unions ignore the high individual and organizational costs of workplace bullying. An additional effect of this lack of research is that it has been difficult to estimate the extent to which the prevalence of bullying varies in different sectors of Danish work-life. Furthermore, the scarcity of research has impeded us from determining whether a low prevalence of bullying is a general characteristic of Scandinavian work-life as indicated by previous Swedish and Norwegian studies. Yet again, making such between-nations comparisons in the prevalence of workplace bullying is difficult given the tendency amongst researchers to employ different ways of measuring bullying. The aims of the present study were: (1) to assess the prevalence of bullying in Danish work-life; (2) to investigate if exposure to bullying behaviours at work is related to self-reported psychological and psychosomatic stress symptoms; (3) to examine potential differences in the prevalence of bullying in various work sectors; (4) to explore the hypothesis that, generally, Scandinavian work-life is characterized by low levels of bullying; and (5) to investigate the extent to which using different criteria for assessing bullying results in disparate prevalence estimates. Results showed that 2-4% of the respondents reported being victims of bullying, in most cases only occasionally. Compared to self-reported bullying, prevalence levels based on an operational definition of bullying (i.e., weekly exposure to one act for at least 6 months) were higher in all the samples, between 8% and 25%. When using a more strict criterion of two acts a week, these figures were significantly reduced. Exposure to bullying was found to be associated with increased self-reported strain reactions.  相似文献
