This study reports the reading difficulties of five children following unilateral left hemisphere stroke sustained either before or during the early stages of literacy acquisition. Although each of the children experienced a period of disturbed language processing in the initial stages postonset, at the time of testing none of the children were considered to be clinically aphasic. Yet, on a standardized test of oral reading each of the children achieved a reading age that lagged behind chronological age and marked reading impairments were disclosed in four of the five children. A set of standardized and nonstandardized tests, aimed at measuring aspects of cognitive and spoken language processing that are considered to be important for normal reading acquisition, was administered. Where nonstandardized tests were used, performance of each of the stroke children was compared to that of groups of normally developing control children, closely matched for chronological age. A range of residual deficits in cognitive and spoken language processing was disclosed among the five brain-damaged children that appeared to be associated with their reading impairments. Two children had expectedly poor reading due to a selective impairment in verbal IQ; a specific phonological reading disorder was revealed in two children, each of which had a residual impairment to phonological awareness; and delayed reading acquisition was observed in one child with a general language deficit. It is suggested that when a child suffers damage to the left hemisphere in the early stages of reading acquisition, difficulties with learning to read are likely to ensue and may arise as a consequence of an underlying cognitive or linguistic deficit. 相似文献

Negative biases in processing information about the self have long been recognised as a central feature in the development and maintenance of clinical depression. In practice, however, it may not be easy to distinguish between patients whose negative thinking about the self is primarily an aspect of current mood state, and those for whom it represents a reflection of more enduring issues (low self-esteem). The paper speculates that, in both cases, metacognitive awareness (acceptance of the idea that thoughts, assumptions and beliefs are mental events and processes rather than reflections of objective truth) may be an important precursor to active engagement in therapy on the part of the patient, and considers what aspects of cognitive therapy might be used to promote it in clinical practice. 相似文献

Little is known about what additional services youth receive while they reside in out-of-home treatment settings. However, such information may be crucial for explaining effectiveness and variation in outcomes for youth in such settings. Our research examines patterns of multi-sector service use for youth in two settings—Therapeutic Foster Care and group homes. Data come from in-person interviews with Treatment Foster Parents and Group Home Staff for a NC state-wide sample of youth with psychiatric disorders and aggressive behavior. Findings indicated high rates of service use by youth in both settings. Analyses indicated significant differences in service types used by youth in each setting, yet similar volume of service use between settings. Clinical and demographic factors did not significantly influence types of services received. Differences in service patterns between the two groups indicated that youth in TFC were more likely to receive community-based, individualized services while youth in group homes were more likely to receive more restrictive services. 相似文献

Familiarized names are falsely judgedfamous more often than nonfamiliarized names. Banaji and Greenwald (1995) demonstrated a gender bias in thisfalse fame effect, with the effect being larger for male than for female names. This effect was interpreted as reflecting the operation of
a gender stereotype. However, the famous male names were, in fact, better known than the famous female names. Thus, the presence
of more famous male names during study may have contributed to the observed male-famous association. If so, there should be
no gender bias if the studied famous male and female names are equally famous, and a reversed gender bias should emerge if
the famous female names are more famous than the male names. In two experiments, these predictions were corroborated. A “classical”
gender bias was found only when the famous males were more famous than the famous females. These findings are consistent with
the hypothesis that the gender bias in fame judgments, rather than showing implicit gender stereotyping in the sense of a
transsituational judgment bias, reflects the fact that, in test, participants select a proportion of fame judgments to male
and female names so that it matches the relative degree of fame of male and female names encountered during study. 相似文献

Considerable research has shown that people have stereotypical beliefs about the speech and communication style of women and men. There is less research about stereotypes of Black people's speech, and none that jointly or comparably investigates communication stereotypes as a function of both gender and race. In this study, White college students (n = 111) rated a fictional character's speech on 36 pairs of words characteristic of communication style (e.g., emotional–unemotional) and also generated dialogue for the character. Targets' race and sex were varied. Results showed that beliefs about speech style were stronger for race than gender. Black speakers, both women and men, were rated as more direct and emotional, and less socially appropriate and playful, than White speakers. The dialogue generated by participants for Black speakers was less grammatical and more profane than for White speakers. Gender effects were consistent with earlier research but suggest a weakening of stereotypes; women's speech was seen as somewhat less direct and more emotional than men's speech. Beliefs about speech and communication style are important because they may function not only to describe what is but to prescribe what should be in social interaction. 相似文献

It has been the matter of some debate why we can experience vivid dynamic illusions when looking at static pictures composed from simple black and white patterns. The impression of illusory motion is particularly strong when viewing some of the works of 'Op Artists, such as Bridget Riley's painting Fall. Explanations of the illusory motion have ranged from retinal to cortical mechanisms, and an important role has been attributed to eye movements. To assess the possible contribution of eye movements to the illusory-motion percept we studied the strength of the illusion under different viewing conditions, and analysed the gaze stability of observers viewing the Riley painting and control patterns that do not produce the illusion. Whereas the illusion was reduced, but not abolished, when watching the painting through a pinhole, which reduces the effects of accommodation, it was not perceived in flash afterimages, suggesting an important role for eye movements in generating the illusion for this image. Recordings of eye movements revealed an abundance of small involuntary saccades when looking at the Riley pattern, despite the fact that gaze was kept within the dedicated fixation region. The frequency and particular characteristics of these rapid eye movements can vary considerably between different observers, but, although there was a tendency for gaze stability to deteriorate while viewing a Riley painting, there was no significant difference in saccade frequency between the stimulus and control patterns. Theoretical considerations indicate that such small image displacements can generate patterns of motion signals in a motion-detector network, which may serve as a simple and sufficient, but not necessarily exclusive, explanation for the illusion. Why such image displacements lead to perceptual results with a group of Op Art and similar patterns, but remain invisible for other stimuli, is discussed. 相似文献

The acute effects of alcohol on cognitive processing of expectancy violations were investigated using event-related brain potentials and a cued recall task to index attentional and working memory processes associated with inconsistency resolution. As predicted, expectancy-violating behaviors elicited larger late positive potentials (LPP) and were recalled better than expectancy-consistent behaviors. These effects were moderated by alcohol and the valence of initial expectancies. For placebo group participants, positive targets performing negative behaviors elicited the largest LPP responses and were recalled best. For those in the alcohol groups, negative targets behaving positively elicited the largest LPP and recall responses. These findings suggest that alcohol does not globally impair working memory processes in person perception but instead changes the nature of valenced information processing. Findings are discussed in the context of alcohol's effects on working memory processes, reward sensitivity, and the prefrontal cortical structures thought to mediate them. 相似文献
