This work seeks to develop an index of the consumer's felt commitment towards the retailer through a formative scale. By using structural equation modeling (SEM), in particular the multiple indicators and multiple causes (MIMIC) model, as well as reflective and formative indicators, the methodology developed by Diamantopoulos and Winklhofer is applied in order to construct this index. To clarify the whole meaning of the concept, the article undertakes a thorough review of literature on felt commitment and formative index development. Several MIMIC models are developed in order to validate the index. The empirical study was carried out in the financial services sector. 相似文献

Early neuropsychological correlates of later clock drawing and clock copying abilities among school aged children. 总被引:3,自引:0,他引:3
Although widely used in empirical study and bedside neuropsychological evaluation of geriatric populations, there is little literature on clock copying and drawing among children. However, existing research suggests that clock drawing tests (CDTs) may be effective and efficient tools for assessing neurocognitive development in children. This paper reports data on clock drawing on demand (CDT-D) and clock drawing to copy (CDT-C) among a non-clinical sample of elementary school aged children and identifies predictive relationships between earlier measures of executive function, visuo-construction, and visual-motor coordination and CDT performance 3 years later. Similar to findings with adult samples, analyses revealed better performance on copying than on drawing. Longitudinal analyses indicate that general intelligence significantly predicted performance on both tasks. Visual-motor coordination only predicted performance on the drawing on demand subtest of the CDT. 相似文献

The present study investigated whether expertise with letter string processing influences visual short-term memory capacity. Specifically, we examined whether performance in a change-detection task would vary as a function of stimulus type (letters vs. symbols) and type of display (horizontal, vertical, and circular). Participants were asked to detect a one-character change in a briefly presented character array following a delay of 900?ms. Concurrent articulation was used to limit effects of rehearsal. Type of display significantly affected performance with letters, but not with symbols, with a selective increase in change-detection accuracy for horizontally presented letter arrays compared with vertical and circular arrays. These findings confirm the standard limits of storage in visual short-term memory, but critically reveal a selective advantage for letter arrays over symbol arrays when presented horizontally. Such an advantage is probably due to the utilization of a specialized encoding mechanism built up over years of reading experience. 相似文献

This article reviews research into the use of virtual reality in the study, assessment, and treatment of body image disturbances in eating disorders and nonclinical samples. During the last decade, virtual reality has emerged as a technology that is especially suitable not only for the assessment of body image disturbances but also for its treatment. Indeed, several virtual environment-based software systems have been developed for this purpose. Furthermore, virtual reality seems to be a good alternative to guided imagery and in vivo exposure, and is therefore very useful for studies that require exposure to life-like situations but which are difficult to conduct in the real world. Nevertheless, review highlights the lack of published controlled studies and the presence of methodological drawbacks that should be considered in future studies. This article also discusses the implications of the results obtained and proposes directions for future research. 相似文献

Géraldine Mossière 《Contemporary Islam》2012,6(2):115-134
My ethnographic fieldwork conducted with female converts to Islam in France and in Quebec (Canada) shows that, for these women, being Muslim does not necessarily mean wearing clothes with ‘oriental’ designs. Rather, they are starting their own clothing companies so as to produce distinct Muslim-Western fashions that they promote through the Internet. By interpreting Islam in a context where Muslims are a minority religious group, converts construct alternative religious and social representations of Muslim identity that accord with their feminist interpretation of the Qu’ran while simultaneously incorporating the Western background within which they were socialized. In this regard, the strategies that they develop for wearing the veil and for integrating into their environment (family, workplace, etc.) make it clear that fashion, religion and politics are interacting in multiple, creative ways. In this paper, I look at how new Muslim feminist subjectivities are produced and realized through habits of dress, resulting in new representations of the body. I explore this issue by considering dress and hairstyle strategies developed by Muslim converts, in order to examine new perspectives on the place of gender in religion as it relates to particular social contexts. 相似文献

The accuracy of force perception during muscular contraction has not been studied extensively, despite its importance in rehabilitation and training. The purpose of this study was to quantify the errors made by healthy young and elderly individuals in their perceptions of force produced at the knee. Four different tasks were used to evaluate the perception of force and the effect of a sensory-motor reference and simultaneous contraction on the accuracy of perception. The absolute errors were similar between groups, with values of 11.9% to 16.3%, depending on the task. The raw perception errors were greater for high levels of force (>50% of the maximal voluntary contraction, or MVC), indicating an overestimation of the forces produced for both groups. At 70% MVC, the sensory-motor reference reduced raw perception errors, and the simultaneous contraction improved the accuracy of force production. Healthy young and elderly individuals had about the same capacity to judge the muscular force of their knee extensors. Therapists involved in the training of active?elderly?individuals should be aware that the accuracy of force perception is not perfect and that these clients have the same ability as young individuals to perceive their knee extension strength. 相似文献

The sources of forgetting in working memory (WM) are a matter of intense debate: Is there a time-related decay of memory traces, or is forgetting uniquely due to representation-based interference? In a previous study, we claimed to have provided evidence supporting the temporal decay hypothesis (S. Portrat, P. Barrouillet, & V. Camos, 2008). However, reanalyzing our data, S. Lewandowsky and K. Oberauer (2009) demonstrated that they do not provide compelling evidence for temporal decay and suggested a class of alternative models favoring a representation-based interference account. In this article, we develop from the most recent proposals made by Lewandowsky and Oberauer 2 of the most plausible extensions of these alternative models. We show that neither of these extensions can account for recent findings related to between-domain WM performance and that both lead to predictions that are contradicted by new empirical evidence. Finally, we show that recent studies that have been claimed to rule out the temporal decay hypothesis do not resist close scrutiny. We conclude that the time-based resource-sharing model remains the most parsimonious way to account for forgetting and restoration of memory traces in WM. 相似文献

Attention and cognitive control networks assessed in a dichotic listening fMRI study 总被引:1,自引:0,他引:1
A meaningful interaction with our environment relies on the ability to focus on relevant sensory input and to ignore irrelevant information, i.e. top-down control and attention processes are employed to select from competing stimuli following internal goals. In this, the demands for the recruitment of top-down control processes depend on the relative perceptual salience of the competing stimuli. In the present functional magnetic resonance imaging (fMRI) study, we investigated the recruitment of top-down control processes in response to varying degrees of control demands in the auditory modality. For this purpose, we tested 20 male and 20 female subjects with a dichotic listening paradigm, in which the relative perceptual salience of two simultaneously presented stimuli was systematically manipulated by varying the inter-aural intensity difference (IID) and asking the subjects to selectively attend to either ear. The analysis showed that the interaction between IID and attentional direction involves two networks in the brain. A fronto-parietal network, including the pre-supplementary motor area, anterior cingulate cortex, inferior frontal junction, insula and inferior parietal lobe, was recruited during cognitively demanding conditions and can thus be seen as a top-down cognitive control network. In contrast, a second network including the superior temporal and the post-central gyri was engaged under conditions with low cognitive control demands. These findings demonstrate how cognitive control is achieved through the interplay of distinct brain networks, with their differential engagement determined as a function of the level of competition between the sensory stimuli. 相似文献
