The model of commitment presented in the present report postulates personality to be the crucial element in the development and maintenance of commitment to the profession of art. The objectives of the research reported here were to (a) demonstrate the typicality of the artist personality and (b) identify the traits which characterize committed and uncommitted artists. Three groups of artists were compared: mature established artists described as committed over a lifetime, committed art students, and uncommitted art students. The instrument used to evaluate personality was the Adjective Check List (ACL; Gough 8c Heilbrun, 1983). Both committed and uncommitted artists presented a typical personality structure; but in contrast to the committed, the uncommitted were characterized by low self‐esteem, a negative self‐image, impaired motivation, low staying power, and an inability to find a clear direction. Both art students and mature artists agreed about the order of importance of 11 factors considered to be determinants of committment. They both placed particular emphasis on autonomy, possibility to experiment, ease of inspiration, and early identification with the profession.  相似文献

The goal of this study was to determine whether a sensorimotor or cognitive encoding is used to encode a target position and save it into iconic memory. The methodology consisted of disrupting a manual aiming movement to a memorized visual target by displacing the visual field containing the target. The nature of the encoding was inferred from the nature and the size of the errors relative to a control. The target was presented either centrally or in the right periphery. Participants moved their hand from the left to the right of fixation. Black and white vertical stripes covered the whole visual field. The visual field was either stationary throughout the trial or was displaced to the right or left at the extinction of the target or at the start of the hand movement. In the latter case, the displacement of the visual field obviously could only be taken into account by the participant during the gesture. In this condition, our hypothesis was that the aiming error would follow the direction of visual field displacement. Results showed three major effects: (1) Vision of the hand during the gesture improved the final accuracy; (2) visual field displacement produced an underestimation of the target distance only when the hand was not visible during the gesture and was always in the same direction displacement; and (3) the effect of the stationary structured visual field on aiming precision when the hand was not visible depended on the distance to the target. These results suggest that a stationary structured visual field is used to support the memory of the target position. The structured visual field is more critical when the hand is not visible and when the target appears in peripheral rather than central vision. This suggests that aiming depends on memory of the relative peripheral position of the target (allocentric reference). However, in the present task, cognitive encoding does not maintain the "position" of the target in memory without reference to the environment. The systematic effect of the visual field displacement on the manual aiming suggests that the role of environmental reference frames in memory for position is not well understood. Some studies, in particular those of Giesbrecht and Dixon (1999) and Glover and Dixon (2001), suggested differing roles of the environment in the retention of the target position and the control of aiming movements toward the target. The present observations contribute to understanding the mechanism involved in locating and grasping objects with the hand.  相似文献

Working memory allows complex information to be remembered and manipulated over short periods of time. Correlations between working memory and mathematics achievement have been shown across the lifespan. However, only a few studies have examined the potentially distinct contributions of domain-specific visuospatial and verbal working memory resources in mental arithmetic computation. Here we aimed to fill this gap in a series of six experiments pairing addition and subtraction tasks with verbal and visuospatial working memory and interference tasks. In general, we found higher levels of interference between mental arithmetic and visuospatial working memory tasks than between mental arithmetic and verbal working memory tasks. Additionally, we found that interference that matched the working memory domain of the task (e.g., verbal task with verbal interference) lowered working memory performance more than mismatched interference (verbal task with visuospatial interference). Findings suggest that mental arithmetic relies on domain-specific working memory resources.  相似文献

The aim of this study was to examine the relationships between cybervictimization and three body-related concerns: body-esteem, self-objectification, and internalization of body ideals. The aim was also to examine these relationships not only to cybervictimization in general but also to appearance-related cybervictimization more specifically. The sample comprised 482 adolescents (233 girls and 247 boys aged 13–15; two participants did not answer the question about gender) from four Swedish schools. The results showed that victims of appearance-related cyberbullying suffered from more body-related concerns: they had a poorer view of their general appearance and of their weight. They also reported more body shame, thin-ideal internalization, and appearance-related pressure from the media. This study shows that cyberbullying that focuses on the victim's appearance is associated with several body-related concerns that have not previously been studied. A novel finding was also that body-related concerns were not related to cyberbullying in general, as has been implied in earlier research, but specifically related to cyberbullying directed at the victim's appearance. The findings suggest that there is a need to include attention to the specific relationships between appearance-related cyberbullying and body-related concerns in future prevention and intervention work.  相似文献

Opportunities to learn and apply new skills are generally considered a favourable job characteristic, but can there be too much of a good thing? In this paper, we draw on vitamin and resource perspectives to investigate a more nuanced perspective on where, when and why skill utilisation delivers value as a resource. Specifically, we examine whether skill utilisation exhibits non-linear relationships with job satisfaction and absenteeism in the presence of two different job demands: task workload, which captures the quantitative demands of work, and surface acting, which captures the qualitative demands of work. Using data from 278 hospital employees, we found that surface acting moderated the non-linear relationship between skill utilisation and absenteeism. Specifically, the relationship between skill utilisation and absenteeism became increasingly positive when surface acting was high, but not when surface acting was low. Interestingly, the linear relationship between skill utilisation and job satisfaction was less positive when surface acting was high. Task workload did not interact with skill utilisation to predict employee outcomes. Our findings highlight complexities in the relationship between job resources and demands and show that the value of skill utilisation changes under demanding conditions.  相似文献
