Although a few developmental fMRI studies have shed some light on the neurological development of either object or spatial processing we still know very little about the development of the ‘what’ and ‘where’ processing systems. The present study is the first to address this issue by comparing, concurrently and within the same behavioral paradigm, patterns of functional activation for face processing and location processing in 12 children (10–12 years old) and 16 adults. For both tasks this study found a developmental shift from a more distributed pattern of activation in children to a more focused pattern of activation in adults. Furthermore, the type of developmental redistribution of activation in children varied depending on the task. The present findings have important implications for theories of visuospatial development. They suggest that the neural systems involved in face and location processing may undergo development and fine‐tuning well into late childhood. 相似文献

Strawson suggests an anti‐sceptical strategy which consists in offering good reason for ignoring scepticism rather than trying to refute it, and the reason he offers is that beliefs about the external world are indispensable to us. I give an exposition of Strawson's arguments for the indispensability thesis and explain why they are not strong enough. I then propose an argument based on some of Davidson's ideas in his theory of radical interpretation, which I think can establish the indispensability thesis. Finally, I spell out the force of Strawson's anti‐sceptical strategy by arguing that we have good reason for ignoring scepticism not only because beliefs about the world are indispensable, but also because it is irrational to have both beliefs about the world and sceptical doubts. 相似文献

Based on a model on spumed helpers’ reactions, a spurning scale for nurses was constructed with items to assess the extent
to which practicing nurses experience recurrent rejection of their help by patients and colleagues. Three approaches were
employed to examine the validity of the scale: the relationship of the spurning scores with job satisfaction and turnover
scores; the relationships of the spurning scores with burnout scores; and the relationships of the spurning scores with scores
indicative of stress arising from interactions with one's patients, colleagues, and supervisor. Practicing nurses in Hong
Kong (N = 212) who were enrolled in a refresher program of studies responded to a questionnaire containing the variables of
interest. The results offered promising evidence for the validity of the scale. 相似文献

Events occurring during the retention intervals for a 5-min delayed alternation task were used to investigate the factors that influence retroactive interference. Appetitive reinforcement in an E-maze was employed to train rats on the delayed alternation task consisting of a forced-choice (target event) trial followed by a free-choice (test) trial. Occasional probe trials added a potentially interfering event either at the beginning, middle, or end of the retention period. These events also varied in similarity to the target events, ranging from low similarity to the converse of the target event. Interference increased both with the interval between the target and intervening events and with the similarity between the converse of the target event and the intervening event; however, there was no tendency, significant or otherwise, towards an interaction between stimulus similarity and the interval between the target and intervening events. Control groups demonstrated that the interference was of an associative nature and that the interval between the intervening event and the test trial was little consequence. These results are discussed in terms of two separate types of interference: similarity interference which depends on stimulus similarity of the intervening event to the converse of the target event but not on the temporal location of the intervening event, and processing interference which depends on the temporal location of the intervening event but not on its similarity to the converse of the target event. 相似文献

This study examined the effects of programming expertise on the semantic processing of computer programs. Experiment 1 showed that sensitivity to semantic changes (i.e. changes of actual program functions) in a BASIC program recognition task increased with programming experience. No such pattern was observed for surface changes (i.e. changes of program syntax without functional alterations). The magnitude of semantic priming for BASIC keywords in a lexical decision task also increased with expertise, but the pattern was not found with normal English priming. In Experiment 2, novice BASIC programmers detected more semantic changes than the controls (non-programmers) in BASIC programs; the reverse was found for surface changes. Both the controls and the novices detected more semantic than surface changes in English passages. The BASIC priming effect was found only with the novices whereas English priming was demonstrated with both the control and the novice participants. The present findings support the view that the programming expert relies particularly on semantic processing and such reliance is specific to programming activities. Practical implications of the present results are discussed. 相似文献

One objective of the present study was to further establish the external validity for a model on spurned helpers' reactions
through examining the spurning-burnout linkage in practicing nurses. A second objective was to explore whether or not social
support from one's supervisor and one's colleague could reduce the negative impact of spurn-ing on burnout. The last objective
was to assess if workload would add to the effects of spurning on burnout. One-hundred seventy-two practicing nurses in Hong
Kong responded to a questionnaire measuring the variables of interest. The results revealed once again the adverse effects
of spurning on burnout, and that peer support and workload served as important moderators. 相似文献
