Comprehension in "hyperlexic" readers 总被引:11,自引:0,他引:11
Mentally retarded children who can read aloud written words better than one would expect from their Mental Age are often called hyperlexic. The reading comprehension thought to be impaired in such children was investigated in four experiments. Mentally retarded advanced decoders, including autistic and nonautistic children, were compared with younger nonretarded children matched for Mental Age and Reading Age. Experiment 1 established that mildly mentally retarded readers could match sentences to pictures as well as could be expected from their verbal ability. This was the same whether they read the sentences or heard them. Experiment 2 demonstrated that only the more able retarded subjects, but not the less able ones, used sentence context in a normal way in order to pronounce homographs. Experiments 3 and 4 showed that these same more able children could extract meaning at both sentence and story level, and their performance was indistinguishable from that of normal controls. Hence, it is doubtful whether these advanced decoders should be called hyperlexic. In contrast, the readers of relatively low verbal ability performed much worse than their normal controls. Although they could be induced under certain conditions to read sentence-by-sentence rather than word-by-word, they did not do so spontaneously. Furthermore, they did not make use of already existing general knowledge in order to answer questions about the stories they had read. The ability to comprehend in terms of large units of meaning seems to be specifically impaired in these low verbal ability fluent readers. We suggest that it is this impairment that marks true hyperlexia. Since there were no differences between autistic and nonautistic readers on any of our tasks, we conclude that hyperlexia is not an autism-specific phenomenon. 相似文献

Twenty subjects performed one of two types of a two-dimensional tracking task for two 5-min sessions, separated by a 10-min rest. In task I, both the horizontal and the vertical components of target movement were unpredictable. In task II, the horizontal component of target movement was predictable (sinusoidal), while the vertical movement was unpredictable. There was no change in level of performance throughout the 10 min of practice on task I. For task II's predictable component, there were marked within- and between-session improvements in performance; whereas for the unpredictable component there was only a between-session improvement. It is proposed that, in these tracking tasks, improvement with practice depends on the development of programmed sequences of movement which can only occur for predictable target movements. Only after a rest do these programmed sequences become automatic, releasing spare attentional capacity for improving the performance of any unpredictable components of the task. 相似文献

This study attempts to investigate the role of sensorimotor impairments in the reading disability that characterizes dyslexia. Twenty-three children with dyslexia were compared to 22 control children, matched for age and non-verbal intelligence, on tasks assessing literacy as well as phonological, visual, auditory and motor abilities. The dyslexic group as a whole were significantly impaired on phonological, but not sensorimotor, tasks. Analysis of individual data suggests that the most common impairments were on phonological and visual stress tasks and the vast majority of dyslexics had one of these two impairments. Furthermore, phonological skill was able to account for variation in literacy skill, to the exclusion of all sensorimotor factors, while neither auditory nor motor skill predicted any variance in phonological skill. Visual stress seems to account for a small proportion of dyslexics, independently of the commonly reported phonological deficit. However, there is little evidence for a causal role of auditory, motor or other visual impairments. 相似文献

Self-affirming before reading about the link between alcohol and breast cancer promoted increased message acceptance among young women at higher risk. Differences were maintained on variables measured up to 1 month later. Relative to their nonaffirmed counterparts, higher risk, self-affirmed participants had higher ratings of risk, imagination, intention to reduce alcohol consumption, and negative affect, such as fear, while reading the leaflet. In contrast, there were no differences between the groups on measures of broader message acceptance (belief in the link, evidence strength). Thus, self-affirmation promoted acceptance of the personal relevance of the message, a critical step in the precaution adoption process. Overall, the findings support the view that self-affirmation in an unrelated domain can offset defensive processing of a threatening health message, promoting central route persuasion and producing consequential and durable increases in message acceptance. 相似文献

This article provides an introduction and overview of sensory integration theory as it is used in occupational therapy practice for children with developmental disabilities. This review of the theoretical tenets of the theory, its historical foundations, and early research provides the reader with a basis for exploring current uses and applications. The key principles of the sensory integrative approach, including concepts such as "the just right challenge" and "the adaptive response" as conceptualized by A. Jean Ayres, the theory's founder, are presented to familiarize the reader with the approach. The state of research in this area is presented, including studies underway to further delineate the subtypes of sensory integrative dysfunction, the neurobiological mechanisms of poor sensory processing, advances in theory development, and the development of a fidelity measure for use in intervention studies. Finally, this article reviews the current state of the evidence to support this approach and suggests that consensual knowledge and empirical research are needed to further elucidate the theory and its utility for a variety of children with developmental disabilities. This is especially critical given the public pressure by parents of children with autism and other developmental disabilities to obtain services and who have anecdotally noted the utility of sensory integration therapy for helping their children function more independently. Key limiting factors to research include lack of funding, paucity of doctorate trained clinicians and researchers in occupational therapy, and the inherent heterogeneity of the population of children affected by sensory integrative dysfunction. A call to action for occupational therapy researchers, funding agencies, and other professions is made to support ongoing efforts and to develop initiatives that will lead to better diagnoses and effective intervention for sensory integrative dysfunction, which will improve the lives of children and their families. 相似文献

This study examined the effects of client-centred therapy (CCT) on the coping strategies of sexually harassed students in tertiary institutions in Taraba State, Nigeria. It also looked for any gender differences in the effect of CCT on the coping strategies of sexually harassed students. We employed a quasi-experimental and pretest–post-test design with control group. The statistical population comprised 250 students who had experienced sexual harassment in tertiary institutions, of which 20 students were selected using convenience sampling. The students who had been sexually harassed were then randomly assigned to the experimental and control groups. The experimental group subsequently underwent six 60-min sessions of CCT, while the control group received placebo treatment on drug abuse. The research tools included a sexual harassment battery (SHB). Inferential statistics of analysis of covariance (ANCOVA) was used to analyse the data. Cronbach's alpha produced a reliability coefficient of 0.79 for the SHB. The following findings were recorded: (i) client-centred therapy effectively increased the coping strategies of students and (ii) there was no significant mean difference between male and female students in the effectiveness of CCT on coping strategies. 相似文献

Two studies which investigated gender-based decision making in an occupational setting are reported. Participants judged the suitability of a male or a female applicant with identical résumés for a male-dominated or a female-dominated position. In Study 1. where participants gave their own judgments of the suitability of the applicants for the positions, there was no evidence of gender-based biases. In Study 2. participants were required to take the perspective of the applicant in providing their judgments of suitability. In this experiment, gender-based biases were apparent, with a positive bias toward the male applicant. Results are discussed in terms of occupational stereotyping and subtle sexism. 相似文献

In this paper we will suggest that impairments in domain-specific functions may have wide-ranging developmental effects which mimic domain-general impairments. This may explain why ‘pure’ cases of developmental disorders are rare. The understanding of autism and dyslexia has been advanced by theories postulating failure of a specific mechanism against a background of unimpaired general processing. Impairment in the mechanisms underlying ‘theory of mind’ in autism, and ‘phonology’ in dyslexia, predict and explain the pattern of poor and good performance on a range of experimental and real-life tasks. However, existing accounts deal largely with the on-line effects of modular deficits, and can be criticised as not truly developmental. Here we attempt to trace developmental or down-stream effects of specific impairments in mentalising and phonological processing. We argue that these modules act as vital gatekeepers in development. Important in this process is the interaction of cognition with socio-cultural environment, an effect well-illustrated by cross-language differences in dyslexia. We claim that consideration of these developmental effects makes clear why postulating specific impairments may be sufficient for explaining more general deficits. 相似文献

Leslie (1987b) proposed a new, metarepresentational model for the cognition of pretense. This model identified a cognitive component necessary for the normal development of a "theory of mind." In this article, the relation of the child's early affective sensitivities to this component is considered. Early affective sensitivities seem to be cognitively distinct from the metarepresentational component. Childhood autism provides an interesting opportunity to study this problem. Three theoretical possibilities for the pathogenesis of this condition are presented: (a) a basic affective disorder as proposed by Hobson (this issue, p. 114), (b) a basic affective disorder and a basic cognitive disorder jointly, and (c) a basic cognitive disorder. There is little evidence for Option a, and a growing body of evidence supports Option c. Option b is sidelined for the time being on grounds of parsimony. Leslie's original theoretical proposals are revised, and some resulting implications are presented for the future investigation of the cognitive neuropsychology of autism. 相似文献

The use of peer-training procedures by moderately mentally retarded adolescents was evaluated in two experiments. In Experiment 1, 2 students received instruction on peer-training skills to teach a vocational task to 7 classmates. Following instruction, both peer trainers were successful in teaching their classmates to perform the target task and a second untrained (generalization) task. In Experiment 2, 1 peer trainer taught 3 peers to use picture prompts to complete one or two complex vocational tasks. Following instruction by the peer trainer, the trainees independently used novel pictures on novel tasks. The results of both experiments indicate that peer training with moderately handicapped students can be an effective instructional procedure, with generalization occurring for both the trainers (Experiment 1) and the trainees (Experiment 2). 相似文献
