To examine how readers of Chinese and English take advantage of orthographic and phonological features in reading, the authors investigated the effects of spelling errors on reading text in Chinese and English using the error disruption paradigm of M. Daneman and E. Reingold (1993). Skilled readers in China and the United States read passages in their native language that contained occasional spelling errors. Results showed that under some circumstances very early phonological activation can be identified in English, but no evidence for early phonology was found in Chinese. In both languages, homophone errors showed a benefit in measures of later processing, suggesting that phonology helps readers recover from the disruptive effects of errors. These results suggest that skilled readers take advantage of the special features of particular orthographies but that these orthographic effects may be most pronounced in the early stages of lexical access.  相似文献

The authors investigated the effects of religiosity and negative affect on beliefs in the paranormal and supernatural among 94 undergraduate students enrolled in psychology classes at a small, private U.S. university. They hypothesized that religiosity would predict differential beliefs in the supernatural versus the paranormal but that negative affect would attenuate these beliefs. In addition, the authors predicted that belief in the supernatural and negative affect would interact to predict belief in the paranormal. Overall, the results were consistent with predictions. The religious participants were skeptical of paranormal phenomena but were accepting of supernatural phenomena. In addition, increased reports of negative affect over the preceding year appeared to attenuate belief in the supernatural for the religious participants. By contrast, for the nonreligious participants, increased belief in both the supernatural and paranormal was predicted when reports of negative affect were high. Finally, the interaction of supernatural belief and negative affect significantly predicted belief in the paranormal.  相似文献

Contemporary theories of associative learning require cues be trained in compound for cue competition (interference) to occur. That is, Cues A and X should compete for behavioral control only if training consists of AX-outcome (O) trials and not if each cue is separately paired with O (i.e., X-O and A-O). Research with humans challenges this view by showing that A-O trials interpolated between training and testing of a X-O association impair responding to X (i.e., retroactive interference). In six conditioned suppression studies with rats, the authors demonstrate that two cues trained apart can each interfere with the potential of the other to predict the outcome. The authors conclude that this type of interference (a) reflects a failure to retrieve the target association due to priming at test of the interfering association and (b) is attenuated if the outcome is of high biological significance. These findings parallel previous reports in verbal learning research and suggest that a similar associative structure underlies some types of associations in nonverbal subjects.  相似文献

This article discusses conceptual issues relevant to the prospective diagnosis of the schizophrenic prodrome. Recent efforts to diagnose these patients with operational criteria based on current symptoms are reviewed. Symptomatic patients so identified appear to be treatment-seeking and to have mild cognitive impairments. In addition to being currently symptomatic, these patients are imminently at risk for progression of illness and development of schizophrenia. Data from three international centers suggest that this risk is approximately 40% over the next year of follow-up if untreated. The implications of the reviewed data for the appropriateness of the term "prodromal" and for treatment/prevention research for these patients are discussed.  相似文献

Several neuroimaging studies have reported that older adults show weaker activations in some brain areas together with stronger activations in other areas, compared with younger adults performing the same task. This pattern may reflect neural recruitment that compensates for age-related neural declines. The recruitment hypothesis was tested in a visual laterality study that investigated age differences in the efficiency of bihemispheric processing. Letter-matching tasks of varying complexity were performed under two conditions: (a) matching letters projected to the same visual field (hemisphere) and (b) matching letters projected to opposite visual fields (hemispheres). As predicted by the recruitment hypothesis, older adults generally performed better in the bilateral than unilateral condition, whereas younger adults showed this pattern onlyfor the most complex task. We discuss the relation between these results and neuroimaging evidence for recruitment, and the relevance of the present bihemispheric advantage to other evidence for age-related changes in interhemispheric transfer.  相似文献

Although there is a rich body of research on resiliency, much of the literature fails to include minority youths or does not take into consideration their distinctive racial and environmental circumstances. Additionally, limited attention has been given to protective factors that are unique to nonmajority populations. This article posits that racial socialization and racial identity protect urban African American adolescents against some of the harmful effects of a discriminatory environment. These factors are hypothesized to influence academic achievement-an indicator of resiliency that has been used in many studies. A theoretical framework is provided that combines character development in a hostile environment, bicultural identity, and urban stress models. Implications for practice and future research are discussed.  相似文献

The norm of self-interest   总被引:9,自引:0,他引:9  
The self-interest motive is singularly powerful according to many of the most influential theories of human behavior and the layperson alike. In the present article the author examines the role the assumption of self-interest plays in its own confirmation. It is proposed that a norm exists in Western cultures that specifies self-interest both is and ought to be a powerful determinant of behavior. This norm influences people's actions and opinions as well as the accounts they give for their actions and opinions. In particular, it leads people to act and speak as though they care more about their material self-interest than they do. Consequences of misinterpreting the "fact" of self-interest are discussed.  相似文献

The current study prospectively examined the impact of social support on symptom severity and recovery from episodes in bipolar disorder, both as a direct influence and as a buffer of life events. Fifty-nine individuals with Bipolar I disorder were followed longitudinally with monthly symptom severity interviews. Social support was measured by the Interpersonal Support Evaluation List and the Interview Schedule for Social Interaction, and life events were assessed using the Life Events and Difficulties Schedule. Individuals with low social support took longer to recover from episodes and were more symptomatic across a 6-month follow-up. Results suggest a polarity-specific effect, in that social support influences depression but not mania. Discussion focuses on theoretical implications of a series of polarity-specific findings within the field.  相似文献

Cluster analysis was used to identify subgroups of a sample of 40 patients with borderline personality disorder (BPD). The BPD patients were part of a larger sample that had participated in an intensive, group-oriented Evening Treatment Program. A set of pretherapy outcome measures was used to represent patient "attributes" for the cluster analysis. Eight clusters were identified. Two, each defined by a single patient with pronounced pathology, were deleted from further analyses. In a discriminant-function analysis, four dimensions emerged that differentiated the six remaining clusters. Significant relationships among the four dimensions and measures of therapeutic work and treatment outcome were identified. The relationships reflected the impact of behavioral characteristics associated with BPD on participation in and benefit from intensive group-oriented evening treatment. Implications of these exploratory findings for the understanding and treatment of BPD are discussed.  相似文献

Unlike English, Chinese uses a numerical system for naming months and days. This study explored whether this difference in naming affects the development of simple calendar calculation. Eight- and 10-year-old children as well as undergraduates in China and the United States were asked to name the day or month that comes a specified time before or after a given day or month. In each age group Chinese speakers primarily used calculation based on calendar names to solve these tasks, while English speakers primarily resorted to reciting the names. The magnitude of these differences was substantial; on difficult tasks Chinese fourth graders performed at speeds comparable to those of English-speaking adults. Implications for models of how linguistic structure affects cognition are discussed.  相似文献
