In this article, a 2-dimensional work stressor framework is used to explain inconsistencies in past research with respect to stressor relationships with retention-related criteria. Results of meta-analyses of 183 independent samples indicated that whereas hindrance stressors had dysfunctional relationships with these criteria (negative relationships with job satisfaction and organizational commitment and positive relationships with turnover intentions, turnover, and withdrawal behavior), relationships with challenge stressors were generally the opposite (positive relationships with job satisfaction and organizational commitment and negative relationships with turnover intentions and turnover). Results also suggested that the differential relationships between challenge stressors and hindrance stressors and the more distal criteria (withdrawal behavior and turnover) were due, in part, to the mediating effects of job attitudes. 相似文献

Chimpanzee’s perspective-taking abilities are currently disputed. Here we show that in some food competition contexts, subordinate
chimpanzees do take the visual perspective of dominant individuals, preferentially targeting a hidden piece of the food that
the dominant cannot see over a piece that is visible to both individuals. However, the space where the animals compete is
critical in determining whether subjects demonstrate this skill. We suggest that competition intensity, as mediated by these
spatial factors, may play an important role in determining the strategy chimpanzees utilize in competitive contexts. Since
some strategies may not require visual perspective taking in order to be successful, chimpanzees may not always demonstrate
this skill. Differences in spatial arrangement may therefore account for the conflicting results of past studies. 相似文献

The importance of optimal visual function in demanding interceptive tasks is far from established. The aim of the study was to determine whether induced myopic blur and hence sub-optimal visual function would give rise to a detrimental effect on performance in the execution of an interceptive task. The batting performance of grade level cricket players was assessed facing a bowling machine whilst wearing contact lenses of four different refractive conditions (plano (nil), +1.00, +2.00 and +3.00D over-refraction), inducing increasing amounts of myopic blur. Performance for each condition was assessed based both on the shot quality against each delivery judged by a qualified cricket coach blind to each condition, along with an evaluation of the quality of ball-bat contact for each delivery. No significant change was found in batting performance with the introduction of +1.00 and +2.00D of induced myopic blur. A +3.00D over-correction was required before any significant decrease in batting performance was detected, demonstrating that batters needed to be essentially legally blind (as simulated through the use of the +3.00D over-refraction) before there was any significant measurable decrement in batting performance. We concluded that optimal visual correction is not necessarily required for optimal performance in a demanding interceptive task, and that the human perceptual-motor system is capable of compensating for marked alterations in input. 相似文献

The issue of mental illness has been of considerable interest to both of us over the past several years. The first author has taught a course on the subject for a decade, and his recent publications on the subject include several articles on John Nash (Capps, 2003b, 2004a,b, 2005b), a book on mental illness for pastoral care professionals (2005a), and an article on whether William James was a patient at McLean Hospital (2007). The second author has had experience with the mentally ill through his pastoral work at Trenton Psychiatrist Hospital in Trenton, New Jersey, a mental hospital with a rather checkered history (see Scull, 2005), and in Scotland and has also written an article on John Nash (Carlin, 2006). This shared interest, together with evidence that serious mental illness in America has been steadily increasing (Torrey &; Miller, 2001, pp. 295–299), caused us to wonder what sort of attention mental illness has received in our major journals of pastoral care from 1950 to the present. Specifically, has this attention kept pace with the increase in mental illness? 相似文献

Although many previous studies have shown that body-based sensory modalities such as vestibular, kinesthetic, and efferent information are useful for acquiring spatial information about one's immediate environment, relatively little work has examined how these modalities affect the acquisition of long-term spatial memory. Three groups of participants learned locations along a 146 m indoor route, and subsequently pointed to these locations, estimated distances between them, and constructed maps of the environment. One group had access to visual, proprioceptive, and inertial information, another had access to matched visual and matched inertial information, and another had access only to matched visual information. In contrast to previous findings examining transient, online spatial representations, our results showed very few differences among groups in the accuracy of the spatial memories acquired. The only difference was the improved pointing accuracy of participants who had access to proprioceptive information relative to that of participants in the other conditions. Results are discussed in terms of differential sensory contributions to transient and enduring spatial representations. 相似文献

One key desideratum of a theory of blame is that it be able to explain why we typically have differing blaming responses in cases involving significant degrees of luck. T.M. Scanlon has proposed a relational account of blame, and he has argued that his account succeeds in this regard and that this success makes his view preferable to reactive attitude accounts of blame. In this paper, I aim to show that Scanlon's view is open to a different kind of luck-based objection. I then offer a way of understanding moral luck cases which allows for a plausible explanation of our differential blaming responses by appealing to the salience of certain relevant features of the action in question. 相似文献

We examined the effects of retrieval practice for students who varied in working memory capacity as a function of the lag between study of material and its initial test, whether or not feedback was given after the test, and the retention interval of the final test. We sought to determine whether a blend of these conditions exists that maximises benefits from retrieval practice for lower and higher working memory capacity students. College students learned general knowledge facts and then restudied the facts or were tested on them (with or without feedback) at lags of 0–9 intervening items. Final cued recall performance was better for tested items than for restudied items after both 10 minutes and 2 days, particularly for longer study–test lags. Furthermore, on the 2-day delayed test the benefits from retrieval practice with feedback were significantly greater for students with lower working memory capacity than for students with higher working memory capacity (r?=??.42). Retrieval practice may be an especially effective learning strategy for lower ability students. 相似文献
