During development, perceptual processing is tuned to inputs in the environment such that certain frequently encountered classes of stimuli are processed more effectively than similar comparison stimuli. Letters represent a class of stimuli that are encountered frequently in the environment, at least in literate cultures. Thus, the present study examined the development of letter-specific processing in children 6-19 years old by comparing the difference between performance on a letter-matching task and an unfamiliar non-letter-matching task in different subject groups. Results revealed an increase in letter-specific processing with development. Moreover, comparisons of letter-specific processing in groups of subjects matched either in age or reading ability indicate that the emergence of letter-specific processing is linked to increased reading skill, rather than increased age per se. Findings support theories of perceptual expertise, which suggest that skilled processing drives the specialization of perceptual mechanisms for certain classes of stimuli. 相似文献

In an urban sample of 5,595 students in Grades 7–12, the authors found that (a) personalized counseling services that were responsive to student needs enhanced school connectedness, (b) risk factors (e.g., poverty, mobility rates, limited English proficiency) were associated with lower school connectedness scores, and (c) responsive counseling services acted as a protective factor that reduced some of the negative effects of risk factors on school connectedness, and consequently, student success in academic and nonacademic areas. 相似文献
To further advance assessment of patient-reported outcomes, the European Organisation of Research and Treatment of Cancer (EORTC) Quality of Life Group has developed computerized adaptive test (CAT) versions of all EORTC Quality of Life Core Questionnaire (QLQ-C30) scales/items. The aim of this study was to develop and evaluate an item bank for CAT measurement of insomnia (CAT-SL). In line with the EORTC guidelines, the developmental process comprised four phases: (I) defining the concept insomnia and literature search, (II) selection and formulation of new items, (III) pre-testing and (IV) field-testing, including psychometric analyses of the final item bank. In phase I, the literature search identified 155 items that were compatible with our conceptualisation of insomnia, including both quantity and quality of sleep. In phase II, following a multistep-approach, this number was reduced to 15 candidate items. Pre-testing of these items in cancer patients (phase III) resulted in an item list of 14 items, which were field-tested among 1094 patients in phase IV. Psychometric evaluations showed that eight items could be retained in a unidimensional model. The final item bank yielded greater measurement precision than the original QLQ-C30 insomnia item. It was estimated that administering two or more items from the insomnia item bank with CAT results in a saving in sample size between approximately 15–25%. The 8-item EORTC CAT-SL item bank facilitates precise and efficient measurement of insomnia as part of the EORTC CAT system of health-related quality life assessment in both clinical research and practice.
Abstract Patient decision-making has been shown to be far from data-driven which results in serious consequences for physical health and psychological well-being. Cancer patients were found to have made their medical decisions in four ways: information-seeking, information-processing, advice-following, and ruminating. These four ways represent two routes of cognitive processing. The first two exemplify central route processing and the second two exemplify peripheral route processing. Medical decisions have also been shown to be highly influencable based on message presentation. This study represents the first step in applying social influence theory to medical decision-making. The elaboration likelihood model was used to determine whether the variables shown to have influenced routes of processing could predict which decisional style the cancer patients used. Specifically, the elaboration likelihood model of Petty and Cacioppo (1986) was applied as predictors of decisional processing style. Using a discriminant function analysis, the variables motivation (both cognitive and emotional), ability to process, and cognitive responding predicted whether cancer patients made their medical decisions using the four categories of decisional styles. 相似文献
Sex hormones are increasingly implicated in memory formation. Recent literature has documented a relationship between hormones and emotional memory and sex differences, which are likely related to hormones, have long been demonstrated in a variety of mnemonic domains, including false memories. Hormonal contraception (HC), which alters sex hormones, has been associated with a bias towards gist memory and away from detailed memory in women who use it during an emotional memory task. Here, we investigated whether HC was associated with changes in susceptibility to false memories, which may be related to the formation of gist memories. We tested false memory susceptibility using two well-validated false memory paradigms: the Deese–Roediger–McDermott (DRM) task, and a story-based misinformation task. We found that hormonal contraceptive users were less susceptible to false memories compared to non-users in the misinformation task, and no differences were seen between groups on the DRM task. We hypothesise that the differences in false memories from the misinformation task may be related to hormonal contraceptive users' memory bias away from details, towards gist memory. 相似文献
The aim of the present study was to investigate relationships between Effort-Reward Imbalance (ERI) and employee adverse health (i.e., psychosomatic complaints, physical symptoms, and exhaustion). The Effort-Reward Imbalance Model was extended by discriminating three specific rewards separately (i.e., salary, esteem, and job security). A sample of 167 health-care workers was used to test the relationship between ERI (i.e., high effort accompanied with low reward) and employee adverse health with multiple univariate logistic regression analyses. Separate analyses were carried out with a composite reward scale and with each of the three specific reward scales as independent variables. The results indicate that the health outcomes of ERI vary depending on the specific reward that was used. Generally, the most adverse health effects were found for employees who reported both high efforts and low rewards, thus supporting the ERI Model. Moreover, the strongest effects of ERI on employee health were found when esteem was used as a reward indicator. Job security also appeared to be an important reward in this respect, whereas salary did not have strong effects as a result of ERI. Although the ERI Model was merely supported by the results, current findings also indicate it is important to separate different kinds of rewards, especially in health-care work in order to capture the complexity of working with clients as well. 相似文献
