Our perception about the representation and processing of concrete and abstract concepts is based on the fact that concrete words are highly imagined and remembered faster than abstract words. In order to explain the processing differences between abstract and concrete concepts, various theories have been proposed, yet there is no unanimous consensus about its neural implication. The present study investigated the processing of concrete and abstract words during an orthography judgment task (implicit semantic processing) using functional magnetic resonance imaging to validate the involvement of the neural regions. Relative to non-words, both abstract and concrete words show activation in the regions of bilateral hemisphere previously associated with semantic processing. The common areas (conjunction analyses) observed for abstract and concrete words are bilateral inferior frontal gyrus (BA 44/45), left superior parietal (BA 7), left fusiform gyrus and bilateral middle occipital. The additional areas for abstract words were noticed in bilateral superior temporal and bilateral middle temporal region, whereas no distinct region was noticed for concrete words. This suggests that words with abstract concepts recruit additional language regions in the brain. 相似文献

This study examined the moderating role of creative self-efficacy in predictions of employees’ creativity through transformational leadership. Data from a dyadic sample of 424 employees and their immediate supervisors were collected and analyzed. The results signify that transformational leaders promote creativity among their subordinates. Further, a significant moderating role of creative self-efficacy was found in the relationship between transformational leadership and employee creativity. The findings reveal that employees working under transformational leaders more likely to resort creative behavior when they perceive high creative-self-efficacy. 相似文献

Vanadium metal powders, ball milled with different surfactants viz., stearic acid, KCl and NaCl, have been studied by X-ray diffraction and transmission electron microscopy. The surfactants alter the microstructural and morphological characteristics of the powders. Ball milling with stearic acid results in solid-state amorphization, while powders milled with KCl yield vanadium–tungsten carbide nanocomposite mixtures. NaCl proved to be an excellent surfactant for obtaining nanostructured fusion-grade vanadium powders. In order to understand the reaction mechanism behind any interstitial addition in the ball-milled powders, CHNOS analysis was performed. 相似文献

It has been suggested that mild fear may evoke rather than inhibit exploratory responses in rats. The relationship between conditioned fear and exploratory behaviour was analysed in three experiments and there was no evidence that mild fear increased exploration. Conditioned fear was found to be under relatively precise stimulus control and its magnitude was related to the intensities and durations of the unconditioned stimulus, inescapable electric shock. 相似文献

Ninety elementary school teachers, grades 2–6, in two school districts in Ohio were interviewed to obtain information on how they used the results of group IQ tests. Twenty-seven of 90 teachers (30%) reported making “little or no use” of the test scores. Most of these teachers presumably had more faith in their own tools and observations than in the IQ test scores. However, 76 of 90 teachers (84%, including the ones who made little use of the test scores) stated that they used the test scores for one or more purposes. The four most frequently mentioned uses were: (a) “for discussion in parent conferences” (51%); (b) “to know a student's potential and/or determine ability-motivation discrepancy” (42%); (c) “to plan instruction” (39.5%) and (d) “for referral purposes” (29%). The instructional strategies mentioned by the teachers varied and were categorized into 21 categories. 相似文献

This study was designed to ascertain the level of hostility in educated unemployed youth (N = 150) as against employed youth (N = 150) at micro level by employing an Indian adaptation of the Buss-Durkee Hostility Scale. Results of statistical comparison revealed a significant difference between the two groups in terms of hostility and its various dimensions barring indirect aggression, negativism, and verbal aggression. However, both the groups tended to have a moderate amount of hostility and its dimensions. The results further showed the relative standing of the two groups on the dimensions of hostility, positing the job-seekers as possessing a high sense of guilt and low indirect aggression, and the employed youth, being high on irritability, and, like their counterparts, low on indirect aggression. Also, the study indicated a correlation among the dimensions of hostility with one another and with the total scale scores. 相似文献

Augmented reality (AR) has proven to be a potential source of disruption in the marketing discipline. Abundant research has attested to AR's potential by exploring the impact of AR attributes on behavioral intentions and users' attitudes. However, AR's potential to spark customer interactions, co-create value, and foster brand advocacy remains poorly understood. This study explores whether and how AR can turn users into brand advocates. Applying structural equation modeling to a sample of 502 AR users, the study finds that AR empowers users during their shopping experience, creating strong brand attachment and engagement and ultimately leading to brand advocacy. This brand-focused study, which goes beyond the technical aspects of AR, is unique and has the potential to inform the strategic decision-making of managers aiming to enhance the customer experience by means of AR implementation. 相似文献

Background and objective: This study tested three alternative explanations for research indicating a positive, but heterogeneous relationship between self-reported posttraumatic growth (PTG) and posttraumatic stress symptoms (PSS): (a) the third-variable hypothesis that the relationship between PTG and PSS is a spurious one driven by positive relationships with resource loss, (b) the growth over time hypothesis that the relationship between PTG and PSS is initially a positive one, but becomes negative over time, and (c) the moderator hypothesis that resource loss moderates the relationship between PTG and PSS such that PTG is associated with lower levels of PSS as loss increases. Design and method: A nationally representative sample (N?=?1622) of Israelis was assessed at three time points during a period of ongoing violence. PTG, resource loss, and the interaction between PTG and loss were examined as lagged predictors of PSS to test the proposed hypotheses. Results: Results were inconsistent with all three hypotheses, showing that PTG positively predicted subsequent PSS when accounting for main and interactive effects of loss. Conclusions: Our results suggest that self-reported PTG is a meaningful but counterintuitive predictor of poorer mental health following trauma. 相似文献
