The influence of expertise on X-ray image processing 总被引:4,自引:0,他引:4

Observers with four different levels of radiological experience performed a recognition memory task on slides of faces and chest X-ray films. Half of the X-ray films revealed clinically significant abnormalities and half did not. Recognition memory for faces was uniformly high across all levels of radiological experience. Memory for abnormal X-ray films increased with radiological experience and, for the most experienced radiologists, was equivalent to memory for faces. Surprisingly, recognition memory for normal films actually decreased with radiological experience from above chance to a chance level. These results indicate that radiological expertise is associated with selective processing of clinically relevant abnormalities in X-ray images. Expert radiologists appear to process X-ray images the way that we all process faces, by quickly detecting and devoting processing resources to features that distinguish one stimulus from another. However, the selective processing of X-ray films appears to be restricted to clinically relevant abnormalities. As they develop the ability to detect these abnormalities, radiologists appear to lose the ability to detect variations in normal features. 相似文献

This study analyzed generalization effects found associated with a language-training intervention to modify the articulation (/f/ phoneme) of a 3.5-year-old boy. The McLean and Raymore Stimulus Shift Articulation Program was implemented by the subject's mother. This language training program is designed to produce setting generalization effects based on an intratherapy training model (i.e., systematic training is applied in a single setting to promote transfer effects to nontraining environments). The intervention resulted in a significant improvement in the subject's production of the /f/ phoneme within the clinical setting in response to untrained stimuli (stimulus generalization). Additionally, the subject's correct phoneme production was observed to generalize to his home and school settings (setting generalization) under “opportunity loaded” (picture prompts) and “spontaneous” (no prompts) conditions. The results provide case-study evidence that stimulus generalization, both within and across settings, may occur with exclusively intratherapy articulation training. 相似文献

Specific- and partial-source memory: effects of aging 总被引:1,自引:0,他引:1
Normal aging can be associated with impairments in source memory (recollecting an event's context). This study examined the effects of aging on specific-source memory (e.g., remembering which of 4 people spoke a word) and partial-source memory (e.g., remembering the gender of the person who spoke the word). When young and older adults were matched in terms of old-new recognition, age-related deficits were observed on both specific- and partial-source recollection. When the groups were matched on partial-source performance, no disproportionate specific-source impairment was seen. The results suggest that aging does not differentially affect specific- versus partial-source memory. 相似文献

A balanced time perspective can help retaining or improving happiness. Research shows shifts in time perspective while ageing. In order to reach a better understanding of the value of time perspective in different age groups, results are reported of a survey (n = 525), which examines the moderating role of age in the association between time perspective and happiness. Time perspective was measured by the Zimbardo Time Perspective Inventory (ZTPI) (Zimbardo and Boyd in J Personal Soc Psychol 77:1271–1288, 1999) and to measure happiness, the Subjective Happiness Scale of Lyubomirsky and Lepper (Soc Indic Res 46:137–155, 1999) was used. Regression analysis shows that time perspective is indeed associated with happiness and that, although the assumed shifts in time perspective over time were not found, age does act as a moderator of this association. With ageing, the negative association between a past-negative time perspective and happiness weakens. These results add to our understanding of the theoretical concept of time perspective and shed new light on the value of a balanced time perspective for someone’s wellbeing. Theoretical and practical implications of these findings are discussed. 相似文献

The opportunity for patients to request support to die is legalised in several countries and is associated with the development of a social and political debate that has taken place in recent years. We believe that psychologists can contribute to this debate. Here, we conducted a literature and legislation review with the aim of understanding arguments regarding the roles of the psychologist in hastening death. A systematic review of the peer-review literature in this field was carried out. The legislation of each country with hasten death practices was analysed to understand if psychologists are included in the protocols of hasten death practices. Despite a lack of literature, we found competence assessment, communication, psychological counselling, research and training and public policy to be the possible roles of psychologists in requests to hasten death. Based on the review, an agenda for future research is developed. We highlight the importance of psychology, raising its profile in the study of the various forms of death hastening requests. 相似文献

The argument that scarce health care resources should be distributed so that patients in 'need' are given priority for treatment is rarely contested. In this paper, we argue that if need is to play a significant role in distributive decisions it is crucial that what is meant by need can be precisely articulated. Following a discussion of the general features of health care need, we propose three principal interpretations of need, each of which focuses on separate intuitions. Although this account may not be a completely exhaustive reflection of what people mean when they refer to need, the three interpretations provide a starting-point for further debate of what the concept means in its specific application. We discuss combined interpretations, the meaning of grading needs, and compare needs-based priority setting to social welfare maximisation. 相似文献

High functioning children with autism spectrum disorder: a novel test of multitasking 总被引:1,自引:0,他引:1
High functioning children with a diagnosis of autism or Asperger's syndrome (HF-ASD) often experience difficulties organising goal-directed actions in their day-to-day lives, requiring support to schedule daily activities. This study aimed to capture these everyday difficulties experimentally using multitasking, a methodology that taps into the cognitive processes necessary for successful goal-directed activities in everyday life. We investigated multitasking in children with HF-ASD using a novel multitask test, the Battersea Multitask Paradigm. Thirty boys participated in the study, 14 with HF-ASD and 16 typically developing controls, matched for age and IQ. Group differences in multitasking were observed. Participants with HF-ASD were less efficient at planning, attempted fewer tasks, switched inflexibly between tasks and broke performance rules more frequently than controls. 相似文献

Impaired memory retrieval correlates with individual differences in cortisol response but not autonomic response 下载免费PDF全文
Stress can enhance or impair memory performance. Both cortisol release and sympathetic nervous system responses have been implicated in these differential effects. Here we investigated how memory retrieval might be affected by stress-induced cortisol release, independently of sympathetic nervous system stress responses. Thirty-two healthy participants (16 women) learned emotionally arousing and neutral words. One hour later, half of the participants underwent a stressor (cold pressor test) and the other half, a control warm water exposure, both followed by a delayed free recall task. The stressed participants were split into those who did (responders, N = 8) and those who did not (nonresponders, N = 6) show a cortisol response. Both responders and nonresponders showed comparable sympathetic nervous system activity (skin conductance level) during the cold pressor. The cortisol responders recalled significantly fewer words compared to nonresponders, and compared to control participants; this effect was most pronounced for moderately arousing words (compared to highly arousing and neutral words). These results suggest that individual differences in cortisol reactivity affect memory retrieval performance, and help to explain the differential effects of stress on memory. 相似文献
