Graph complexity as measured by topological entropy has been previously shown to affect performance on artificial grammar learning tasks among typically developing children. The aim of this study was to examine the effect of graph complexity on implicit sequential learning among children with developmental dyslexia. Our goal was to determine whether children’s performance depends on the complexity level of the grammar system learned. We conducted two artificial grammar learning experiments that compared performance of children with developmental dyslexia with that of age- and reading level-matched controls. Experiment 1 was a high topological entropy artificial grammar learning task that aimed to establish implicit learning phenomena in children with developmental dyslexia using previously published experimental conditions. Experiment 2 is a lower topological entropy variant of that task. Results indicated that given a high topological entropy grammar system, children with developmental dyslexia who were similar to the reading age-matched control group had substantial difficulty in performing the task as compared to typically developing children, who exhibited intact implicit learning of the grammar. On the other hand, when tested on a lower topological entropy grammar system, all groups performed above chance level, indicating that children with developmental dyslexia were able to identify rules from a given grammar system. The results reinforced the significance of graph complexity when experimenting with artificial grammar learning tasks, particularly with dyslexic participants.  相似文献

This paper explores implicit learning in typically developing and primary school children (9–12 years old) with developmental dyslexia using an artificial grammar learning (AGL) task. Two experiments were conducted, which differed in time of presentation and nature of the instructional set (experiment 1—implicit instructions vs experiment 2—explicit instructions). Repeated measures analysis of variance (group × grammaticality × chunk strength) showed a group effect only in experiment 1 (implicit instructions), with only the typically developing children showing evidence of AGL. There was a grammaticality effect (adherence to the rules) for both groups in the two experimental situations. We suggest that the typically developing children exhibited intact implicit learning as manifested in AGL performance, whereas children with developmental dyslexia failed to provide such evidence due to possible mediating cognitive developmental factors.  相似文献

This study investigates the implicit sequence learning abilities of dyslexic children using an artificial grammar learning task with an extended exposure period. Twenty children with developmental dyslexia participated in the study and were matched with two control groups—one matched for age and other for reading skills. During 3 days, all participants performed an acquisition task, where they were exposed to colored geometrical forms sequences with an underlying grammatical structure. On the last day, after the acquisition task, participants were tested in a grammaticality classification task. Implicit sequence learning was present in dyslexic children, as well as in both control groups, and no differences between groups were observed. These results suggest that implicit learning deficits per se cannot explain the characteristic reading difficulties of the dyslexics.  相似文献

The importance of feedback for learning has been firmly established over the past few decades. The question of whether feedback plays a significant role in the statistical learning abilities of adults with dyslexia, however, is currently unresolved. Here, we examined the role of feedback in grammaticality judgment, type of structural knowledge, and confidence rating in both typically developed and dyslexic adults. We implemented two artificial grammar learning experiments: implicit and explicit. The second experiment was directly analogous to the first experiment in all respects except training format: the standard memorization instruction was replaced with an explicit rule-search instruction. Each experiment was conducted with and without performance feedback. While both groups showed significantly improved learning in the feedback-based explicit artificial grammar learning task, only the typically developed adults demonstrated higher levels of conscious structural knowledge. The present study demonstrates that the basis for the grammaticality judgment of adults with dyslexia differs from that of typically developed adults, regardless of increase in the level of explicitness.  相似文献

语块学习有利于提高语言输出和表达的流利性、地道性和生动性。从222名非英语专业学生语块学习策略、语块能力和四级成绩调查结果来看,可以得出以下结论:学生坚持学习语块时需要背诵和用中学两种观念;常用猜测、查词典、记笔记和重复等策略,较少使用元认知、社会情感、编码、活用等策略;语块能力和常用的4种策略不存在相关,但与较少使用的4种策略相关。同时,四级成绩和语块能力之间存在相关;访谈报告支持以上结果。  相似文献

This study examined whether the characteristic reading speed impairment of German dyslexic children results from a general skill-automatization deficit sensu Nicolson and Fawcett (1990) or from more specific deficits in visual naming speed and phonological skills. The hypothesized skill-automatization deficit was assessed by balancing, peg moving, and visual search. Rapid "automatized" naming tasks served as measures of impaired visual naming speed, and the phonological deficit was assessed by speech perception, phonological sensitivity, and phonological memory tasks. Dyslexic German children and age-matched control children (all boys) were tested at the end of Grade 2 and as participants of a longitudinal study also at the beginning of Grade 1. No evidence for a skill-automatization deficit was found, as the dyslexic children did not differ at all on the balancing tasks and little on the other nonverbal skill tasks. However, the dyslexic children showed impaired visual naming speed and impaired phonological memory performance that were observed not only in Grade 2 but also before learning to read. Overall, the findings support the conclusion that, even in regular orthographies, difficulties in learning to read are due to a phonological deficit and not to a general skill-automatization deficit.  相似文献

This paper investigates Spanish dyslexic spelling abilities: specifically, the influence of syllabic linguistic structure (simple vs consonant cluster) on children's spelling performance. Consonant clusters are phonologically complex structures, so it was anticipated that there would be lower spelling performance for these syllabic structures than in simple ones, because of the poor phonological processing of dyslexic children. The participants were 31 dyslexic children, 31 chronological age‐matched children and 31 reading level‐matched children. A dictation task with words and pseudowords (with and without consonant clusters) was used. Word lexical frequency was controlled. The results show that the spelling of consonant clusters presents difficulties for dyslexic spelling performance despite this structure being orthographically consistent. Dyslexic children present a higher performance difference in items with consonant clusters than in simple items, compared with typically developing children. The work raises questions about the items used for the identification of dyslexic children's difficulties.  相似文献

The present study examines implicit sequence learning in adult dyslexics with a focus on comparing sequence transitions with different statistical complexities. Learning of a 12-item deterministic sequence was assessed in 12 dyslexic and 12 non-dyslexic university students. Both groups showed equivalent standard reaction time increments when the sequence was unexpectedly changed, suggesting that learning of the sequence took place. However, a novel analysis comparing transitions of differing complexity within the learning blocks indicated that dyslexic participants were impaired only for higher-order but not first-order sequence learning. No difference was found in the explicit awareness contribution between the two groups and this was found not to correlate with reaction time performance. This result suggests that statistical complexity of the sequence may account for intact and impaired learning performance in dyslexia.  相似文献

Recent studies have suggested that an increase of inter-letter spacing may improve reading performance of dyslexic readers by reducing visual crowding. However, these results have been difficult to replicate.This study directly compares reading accuracy and comprehension, as well as reading speed, and number and duration of fixations of 38 dyslexic and 32 typically reading children (10–14 years old) in regular, spaced (+2,5 pt), and condensed (−1,5 pt) conditions using a natural sentence-reading paradigm.Inter-letter spacing did not affect reading accuracy, comprehension, or speed. The lack of effects of inter-letter spacing was observed in both dyslexic and typical readers. Inter-letter spacing did not impact the number of fixations, but increased inter-letter spacing led to shorter fixations in dyslexic children. Decreased inter-letter spacing resulted in longer fixations in both groups.These results do not support the claim that dyslexics are more influenced by crowding than age-matched controls.  相似文献

在语言加工双通道论观照下,研究者通过纵向实证方法探究时政文本视域下三种水平译者之块状语表征心理现实性、认知加工范式、转换策略等差异对多字格块状语英译的影响。 结果发现: 1.就低、中水平学生译者而言,六字格块状语翻译质量最低,其次是三字格块状语;2.四字格块状语的翻译质量相对较高,且组间差异也更大;3.从译者水平由低至高的路径来看,不同字格数块状语英译的加工范式呈现出分析性加工范式至整体性加工范式的连续体发展模式;4. 学生译者策略多以异化和直译/硬译为主,专家译者归化、意译策略凸显且稳定。据此,本文得到两点重要启示:学生译者的双语关联块状语表征亟待完善,翻译加工范式及策略的使用偏好有待调控和改进。  相似文献
