The aim of the current study was to investigate the validity and reliability of goal orientation and self-efficacy scales. The scales were administered to 264 university students (154 from engineering departments, 110 from business administration). Two samples were used. In the first sample, the original factor model was tested with confirmatory factor analysis. In the second sample, the Turkish versions of the scales were factor analyzed. Principal components analysis resulted in three components for the Goal Orientation scale: Learning goal orientation, Performance-prove goal orientation, and Performance-avoid goal orientation. The Self-efficacy scale had one factor as expected. Cronbach's alpha coefficients were satisfactory. The results did not fully support the use of current Turkish versions of the scales. Results of the studies are discussed along with the strengths and limitations of the study and suggestions for further development of the scales. 相似文献

The purpose of this study was to assess whether reaction time in persons with intellectual disabilities can be improved with an exercise program. 50 children and adolescents (M age = 14.7 yr., SD = 1.4, range = 11-18) with mild intellectual disability without Downs syndrome were randomly divided into control (20 boys, 5 girls) and experimental (19 boys, 6 girls) groups. The experimental group participated in a structured physical fitness program for 12 weeks. Reaction time was assessed at baseline and after 12 weeks. Significant improvements in reaction time were observed in the exercise group but not for the control group. Results indicated that reaction time can be improved with an exercise program in youth with intellectual disability. 相似文献

The aim of this study is to determine the attitudes and behaviors of religious scholars regarding organ donation and transplantation. In this study, 540 officials working in the Department of Religious Affairs in Kayseri, Turkey, were included. Overall, 86.6% response rate (n = 468) was achieved. Although a majority of the officials of religion in this study stated that they believed in the importance of organ donation (90.8%), the rate of considering donation (57.9%) and the donation rate (1.1%) were found to be substantially low. There is a difference between the employment status and willingness to donate organs. The rate of willingness to donate was significantly high in men than women. And also was high in imams and preachers. Regarding the sources of information, the majority of the respondents (70.0%) cited mass media. Overall, 15.3% cited school education and 42.0% religious publications. The most common question (83.1%) that was asked was “whether or not organ donation was suitable for Muslim religious”. Our study revealed that although the research groups have positive ideas about organ donation and transplantation, their role was low in informing and motivating people about organ donation and transplantation. 相似文献

Dispositional reasoning is defined as general reasoning about traits, behaviors, and situations. Although earlier accuracy studies found that it predicted interview judgment accuracy, they did not distinguish between its underlying components (i.e., trait induction, trait extrapolation, and trait contextualization). This drawback has hampered insight into the nature of the dispositional reasoning construct. Therefore, we use a componential approach to test if dispositional reasoning adheres to classical criteria for an intelligence. Results from 146 managerial interviewers who observed videotaped interviewees showed that the dispositional reasoning components had positive manifold and predicted interview accuracy. Moreover, they demonstrated discriminant validity with personality and incremental validity over cognitive ability in predicting interview accuracy. Together, findings suggest that dispositional reasoning broadly adheres to the classical criteria for an intelligence. 相似文献

The performance effect is used to explain the significant differences between salespersons’ self-evaluation and supervisors’ ratings of job performance. It is shown that bottom performers overestimate, whereas top salespeople underestimate their performance. Also, results indicate that bottom performers are significantly more inaccurate than top salespeople in their job performance estimation. Finally, results indicate that the relationship between inaccuracy of self-evaluation and job performance is curvilinear. Managerial implications are provided as well as directions for future research and limitations. 相似文献

We have fabricated a molecular organic light-emitting device comprising indium–tin oxide/a molecular organic layer/aluminum in which the organic layer is a green fluorescent protein. The device exhibits peak external quantum and power efficiencies of 8?±?0.2% and 13?±?0.7?lm?W???1 at a current of J?=?1.5?A?m?2, respectively. In addition, the turn-on voltage is 2.5?V for 1?cd?m?2 and the maximum luminance achieved is 1275?cd?m?2. This good performance can be explained by the presence of singlet-excited states, leading to a high internal efficiency. 相似文献

Offline verbalization about a new motor experience is often assumed to positively influence subsequent performance. Here, we evaluated this presumed positive influence and whether it originates from declarative or from procedural knowledge using the explicit/implicit motor-learning paradigm. To this end, 80 nongolfers learned to perform a golf-putting task with high error rates (i.e., explicit motor learning), and thus relied on declarative knowledge, or low error rates (i.e., implicit motor learning), and thus relied on procedural knowledge. Afterward, they either put their memories of the previous motor experience into words or completed an irrelevant verbal task. Finally, they performed the putting task again. Verbalization did not improve novice motor performance: Putting was impaired, overall, and especially so for high-error learners. We conclude that declarative knowledge is altered by verbalization, whereas procedural knowledge is not. 相似文献

A large number of studies have shown that effort influences the visual perception of reaching distance. These studies have mainly focused on the effects of reach-relevant properties of the body and of the objects that people intend to reach. However, any influence of the reach-relevant properties of the surrounding environment remains still speculative. We investigated this topic in terms of the role of obstacle width in perceiving distances. Participants had to estimate the straight-line distance to a cylinder located just behind a transparent barrier of varying width. The results showed that participants perceived the straight-line distance to the cylinder as being longer when they intended to grasp the cylinder by reaching around a wide transparent barrier rather than by reaching around narrower ones. Interestingly, this effect might be due to the anticipated effort involved in reaching. Together, our results show that reach-relevant properties of the surrounding environment influence perceived distances, thereby supporting an embodied view of the visual perception of space. 相似文献
