    文本阅读流畅性(TRF)是二、三年级常见的阅读干预目标。TRF需要整合几种技能,从而导致无法流畅阅读的几种途径。然而,当将向下钻取方法应用于干预目标时,在排除解码困难后,指导从业者在阅读连接文本时考虑学生的速度和准确性。仍然存在一个问题,即学生的阅读率和准确性是否对促进TRF的基本技能的差异敏感。我们使用潜在的概况分析来调查是否可以在被推荐进行针对TRF的干预的二年级(n=127)和三年级(n=170)学生中识别出成分阅读技能的不同概况。大多数学生被确定为白人(56%),学生主要讲英语(87%)。在干预开始时,我们测量了参与者的听力理解技能,阅读理解,阅读词汇,单词阅读效率,和解码效率。在影响TRF的组件技能方面,两个年级都出现了四个特征,具有相似的模式。其中两个配置文件中的学生在单词阅读或阅读理解方面表现出相对优势,他们的其他技能接近样本平均水平。第三个配置文件接近所有组件技能的样本平均值,而第四个配置文件低于所有测量技能的样本平均值。然而,一些凭经验得出的概况在学生的平均阅读率方面没有差异。例如,在理解能力相对较强的学生和单词阅读能力相对较强的学生之间,平均每分钟阅读正确的单词没有显着差异。我们的结果表明,学生的文本阅读率和准确性的差异可能并不总是捕捉到影响TRF的技能的潜在相关差异。
    Text reading fluency (TRF) is a common reading intervention target in second and third grade. TRF requires the integration of several skills that result in several pathways to dysfluent reading. However, when applying the drill-down approach to intervention targeting, practitioners are guided to consider students\' rate and accuracy when reading connected text after ruling out decoding difficulties. A question remains whether students\' reading rate and accuracy alone is sensitive to differences in the underlying skills that promote TRF. We used latent profile analysis to investigate whether different profiles of component reading skills could be identified among second- (n = 127) and third-grade (n = 170) students who were referred for an intervention targeting TRF. Most students were identified as white (56%) and students were predominately English speakers (87%). At the beginning of the intervention, we measured participants\' skills in listening comprehension, reading comprehension, reading vocabulary, word reading efficiency, and decoding efficiency. Four profiles emerged in both grades with similar patterns in terms of the component skills influencing TRF. Students in two of the profiles demonstrated relative strengths in word reading or reading comprehension with their other skills near the sample average. A third profile approximated the sample average across all component skills whereas the fourth profile was below the sample average in all measured skills. However, some of the empirically derived profiles did not differ in terms of students\' average reading rate. For example, the average words read correct per minute did not significantly differ between students with relative strengths in comprehension and students with relative strengths with word reading. Our results suggest that differences in students\' text reading rate and accuracy may not always capture potentially relevant differences in the skills that influence TRF.

    阅读技能的获取是一个复杂的过程,需要培养各种领域通用和特定领域的能力。因此,毫不奇怪,许多孩子努力保持年级水平的熟练程度,特别是当面对跨越两个领域的多种能力的挑战时,正如在有阅读困难的个体中观察到的那样。引人注目的是,尽管阅读困难是影响学龄儿童最普遍的神经发育障碍之一,大多数可用的诊断工具缺乏全面的框架来评估与阅读障碍相关的认知技能,与最小的计算机化的选择。值得注意的是,目前,具有这些功能的工具有限,适用于讲西班牙语的儿童。这项研究的目的是描述使用Sicole-R多媒体电池诊断有阅读困难的西班牙语儿童的方案。这个基本成绩的工具侧重于评估与科学文献规定的阅读障碍相关的认知技能。具体来说,它专注于评估一系列认知能力,研究表明这些能力与阅读障碍有关。这个焦点是基于这样的观察,即阅读障碍的个体通常在这个数字工具评估的几个认知领域表现出缺陷。证明了电池的强大内部一致性和多维内部结构。这种多媒体电池已被证明是诊断小学阅读困难儿童的合适工具,提供全面的认知概况,不仅对诊断目的有价值,而且对定制个性化的教学计划也有价值。
    The acquisition of reading skills is an intricate process that demands the cultivation of various domain-general and domain-specific abilities. Consequently, it is unsurprising that many children grapple with maintaining proficiency at the grade level, particularly when confronted with challenges spanning multiple abilities across both domains, as observed in individuals with reading difficulties. Strikingly, despite reading difficulties being among the most prevalent neurodevelopmental disorders affecting school-aged children, the majority of available diagnostic tools lack a comprehensive framework for assessing the full spectrum of cognitive skills linked to dyslexia, with minimal computerized options. Notably, there are currently limited tools with these features available for Spanish-speaking children. The aim of this study was to delineate the protocol for diagnosing Spanish-speaking children with reading difficulties using the Sicole-R multimedia battery. This tool for elementary grades focuses on evaluating cognitive skills that are associated with dyslexia as prescribed by the scientific literature. Specifically, it concentrates on assessing a range of cognitive abilities that studies have demonstrated to be linked to dyslexia. This focus is based on the observation that individuals with dyslexia typically exhibit deficits in several of the cognitive areas evaluated by this digital tool. The robust internal consistency and multidimensional internal structure of the battery were demonstrated. This multimedia battery has proven to be a fitting tool for diagnosing children with reading difficulties in primary education, offering a comprehensive cognitive profile that is valuable not only for diagnostic purposes but also for tailoring individualized instructional plans.

    一种有效的眼动评估模式是使用客观眼动跟踪系统与主观测试(NSUCO或DEM)相结合,这很容易适用于所有年龄组和眼部护理临床环境。这项研究的目的是在两组中描述阅读过程中的注视:一组患有神经发育障碍的儿童(NDDG,24个孩子,年龄:6-12岁)和一组有动眼异常但没有NDD的儿童(OAG,24个孩子,年龄:6-12岁)。将获得的结果与对照组的结果进行比较(CG,20个孩子,年龄:6-12岁)。具体来说,用两个主观评分系统获得的结果,东北州立大学验光学院眼动(NSUCO)测试和发育眼动(DEM)测试,与通过市售眼动仪获得的客观分析(TobiiEyeX,Tobii,斯德哥尔摩,瑞典)。专业分析软件,即临床眼动追踪器2020(汤姆森软件解决方案,WelhamGreen,英国),被使用。发现患有NDD的儿童的动眼技能受损。更多的回归,更多的关注,长时间的注视似乎是该人群的特征。此外,有NDD的孩子需要更长的时间来完成DEM测试,以及表现出更多的错误。使用客观的视频眼图系统进行眼睛跟踪和主观测试,如NSUCO或DEM是评估扫视运动的好工具,允许检测NDD儿童的动眼异常。
    An efficient mode of evaluation for eye movements is the use of objective eye tracking systems combined with subjective tests (NSUCO or DEM), which are easily applicable across all age groups and in eye care clinical settings. The objective of this study was to characterize fixations during reading in two groups: a group of children with neurodevelopmental disorders (NDDG, 24 children, age: 6-12 years) and a group of children with oculomotor anomalies but without NDD (OAG, 24 children, age: 6-12 years). The results obtained were compared with those from a control group (CG, 20 children, age: 6-12 years). Specifically, the outcomes obtained with two subjective score systems, the Northeastern State University College of Optometry\'s Oculomotor (NSUCO) test and the Developmental Eye Movement (DEM) test, were compared with the objective analysis obtained through a commercially available eye tracker (Tobii Eye X, Tobii, Stockholm, Sweden). Specialized analysis software, namely Clinical Eye Tracker 2020 (Thomson Software Solutions, Welham Green, UK), was used. It was found that children with NDD had impaired oculomotor skills. A higher number of regressions, more fixations, and longer durations of fixations appear to be characteristic signs of this population group. Additionally, children with NDD took longer to complete the DEM test, as well as exhibiting more errors. The use of objective videoculographic systems for eye tracking and subjective tests like the NSUCO or DEM are good tools to assess saccadic movements, allowing the detection of oculomotor abnormalities in children with NDD.

    早期识别在为学习障碍学生提供及时支持方面起着至关重要的作用,比如诵读困难,为了克服自己的阅读困难。然而,用于识别阅读障碍的方法存在显着差异。本研究旨在探索和了解英国阅读障碍识别的实践。对274名阅读障碍专业人士进行了一项调查,包括教育心理学家和阅读障碍专家,调查他们采用的评估类型,他们利用评估数据的方法,他们的决策过程,以及他们对阅读障碍的概念化。此外,这项研究调查了这些专业人士是否持有与阅读障碍相关的误解或神话。对调查数据的分析显示,专业人士如何概念化阅读障碍,以及评估方法的变化。此外,相当比例的调查受访者赞同一个或多个关于阅读障碍的误解;专业人士中最常见的误解是认为有阅读障碍的儿童以相反的顺序阅读字母。研究结果强调了对阅读障碍识别和揭穿普遍误解的标准化方法的必要性。讨论了这些发现的含义,强调知情的政策和实践在支持学生与阅读障碍的重要性。提供了建议,以提高阅读障碍识别的一致性和准确性,目的是促进对受影响学生的早期干预和支持。
    Early identification plays a crucial role in providing timely support to students with learning disabilities, such as dyslexia, in order to overcome their reading difficulties. However, there is significant variability in the methods used for identifying dyslexia. This study aimed to explore and understand the practices of dyslexia identification in the UK. A survey was conducted among 274 dyslexia professionals, including educational psychologists and dyslexia specialists, to investigate the types of assessments they employ, their approach to utilizing assessment data, their decision-making processes, and their conceptualization of dyslexia. Additionally, the study examined whether these professionals held any misconceptions or myths associated with dyslexia. Analysis of the survey data revealed substantial variability in how professionals conceptualize dyslexia, as well as variations in assessment methods. Furthermore, a significant proportion of the survey respondents subscribed to one or more misconceptions regarding dyslexia; the most common misconception identified among professionals was the belief that children with dyslexia read letters in reverse order. The findings highlight the need for standardized approaches to dyslexia identification and debunking prevailing misconceptions. The implications of these findings are discussed, emphasizing the importance of informed policy and practice in supporting students with dyslexia. Recommendations are provided to enhance consistency and accuracy in dyslexia identification, with the aim of facilitating early intervention and support for affected students.

    演示文稿功能,如拼写、标点符号和笔迹会影响对一般文本质量的评价。因此,患有阅读障碍的高中生可能处于不利地位,因为至少他们的拼写表现通常很差(呃)。此外,这些学生可能会表现出不那么复杂的文本语言特征,如单词长度和句子复杂性,这也可能与文本质量有关。我们比较了荷兰高中生(平均年龄13.7岁)与(n=28)和没有(n=29)阅读障碍的叙述。有阅读障碍的学生的文本包含更多的拼写错误和较差的笔迹质量,但不是更多的标点符号错误。对于未更正版本的阅读障碍学生的文本,教师评定的一般文本质量较低。当拼写和标点符号错误得到纠正时,没有教师评定的文本质量差异出现。没有发现语言文本特征的差异。此外,拼写,标点符号和,在较小程度上,每个句子从句的单词数与参与者的文本质量评分相关.这些结果证实了呈现特征对文本质量评级的影响。他们鼓励教师意识到这种影响,并强调拼写和写作支持和干预在整个教育过程中对阅读障碍学生的重要性。
    Presentation features such as spelling, punctuation and handwriting can influence the evaluation of general text quality. High school students with dyslexia might therefore be at a disadvantage, as at least their spelling performance is typically poor(er). Furthermore, these students might show less sophisticated linguistic features of texts, such as word length and sentence complexity, that might also be related to text quality. We compared narratives written by Dutch high school students (mean age 13.7 years) with (n = 28) and without (n = 29) dyslexia. Students with dyslexia\'s texts contained more spelling errors and poorer handwriting quality, but not more punctuation errors. Teacher-rated general text quality was lower for the texts of students with dyslexia in uncorrected versions. When spelling and punctuation errors were corrected, no teacher-rated text quality differences emerged. No differences in linguistic text features were found. Furthermore, spelling, punctuation and, to a lesser extent, number of words per sentence clause were related to ratings of text quality across participants. These results confirm the influence of presentation features on text quality rating. They encourage teachers to be aware of this effect and emphasize the importance of spelling and writing support and interventions for students with dyslexia throughout education.

    不同的研究试图建立阅读障碍与前庭系统功能之间的关系。主观视觉垂直/水平(SVV和SVH)和视频头部冲动测试(VHIT)对于研究前庭系统很有用,可以在儿童中轻松进行。我们的目的是通过SVV/SVH和VHIT评估阅读障碍儿童的前庭功能。我们招募了18名阅读障碍儿童(10M/8F;平均年龄10.7±2.3岁;范围7-14岁)和18名年龄匹配的儿童,这些儿童具有典型的学习能力发展。所有的孩子都表演了VHIT,SVV和SVH。我们发现,在诵读困难和通常发育中的儿童中,前庭眼反射的正常增益和对称性。18名阅读障碍儿童中的15名(83.3%)在SVV或SVH中至少有一个差异。SVV的平均值为2.3°,SVH的平均值为2.6°。统计分析表明,SVV和SVH的典型发育和阅读障碍儿童之间存在显着差异。我们证实了阅读障碍与SVV和SVH改变之间的关系。我们的结果可能与视觉处理障碍的病因学假设有关,该视觉处理障碍与大细胞途径的功能障碍或与多模态皮层网络有关的一般缺陷有关。
    Different studies have tried to establish a relationship between dyslexia and the vestibular system function. Subjective Visual Vertical/Horizontal (SVV and SVH) and Video Head Impulse Test (VHIT) are useful for studying the vestibular system and can be easily performed in children. Our aim was to evaluate the vestibular function in dyslexic children by SVV/SVH and VHIT. We enrolled 18 dyslexic children (10M/8F; mean age 10.7 ± 2.3 years; range 7-14 years) and 18 age-matched children with typical development of learning abilities. All children performed VHIT, SVV and SVH. We found normal gain and symmetry of vestibulo-ocular-reflex both in dyslexic and typically developing children. Fifteen out of 18 dyslexic children (83.3%) showed a difference of at least one amongst SVV or SVH. The mean value of SVV was 2.3° and the mean value of SVH was 2.6°. Statistical analysis showed a significant difference between typically developing and dyslexic children for both SVV and SVH. We confirm a relationship between dyslexia and the alteration of SVV and SVH. Our results could be related to the pathogenetic hypothesis of a visual processing impairment related to a dysfunction of the magnocellular pathway or to a general deficit related to a multimodal cortical network.

    阅读障碍儿童在阅读习得方面面临持续的困难,导致阅读准确性差。除了经常研究的阅读错误,如遗漏,添加,替换,和字母反转,他们还会出现猜测错误,其特征是用正交邻居替换一个单词。这些错误,发生在孤立的单词和句子或文本阅读的上下文中,可能与已经证明与阅读障碍有关的抑制问题有关。然而,据我们所知,没有实验证据表明,患有阅读障碍的儿童比通常发育中的儿童犯更多的猜测错误,顺序错误的情况也是如此。当前的研究旨在评估阅读障碍儿童是否比通常发育中的儿童犯了更多的猜测错误,以及这些错误在孤立的单词或句子上下文中是否更频繁。
    从4年级开始的28名阅读障碍儿童与按实际年龄或阅读水平的典型发育儿童相匹配。通过单词和文本阅读任务评估阅读。错误类型分为七类并进行分析。
    一项重复测量的方差分析显示,有阅读障碍的儿童有更多的猜测错误,特别是视觉和语素错误,而不是典型的发育中的孩子。此外,在单个单词和句子级别都发现了这些错误。这些发现表明,患有阅读障碍的儿童倾向于使用全球语言治疗,依靠不完全信息来弥补他们的困难。这些发现对教学和治疗方法具有实际意义。
    UNASSIGNED: Children with dyslexia face persistent difficulties in reading acquisition, which results in poor reading accuracy. In addition to the commonly studied reading errors such as omissions, additions, substitutions, and letter reversals, they also make guessing errors characterized by replacing a word with an orthographic neighbor. These errors, which occur in the context of isolated words and sentence or text reading, might be linked to the inhibition issues that have already been demonstrated in connection to dyslexia. However, to the best of our knowledge, there is no experimental evidence that children with dyslexia make more guessing errors than typically developing children, as is the case for sequential errors. The current study aimed to evaluate whether children with dyslexia made more guessing errors than typically developing children and whether these errors were more frequent in an isolated word or sentence context.
    UNASSIGNED: Twenty-eight children with dyslexia from Grade 4 were matched with typically developing children by either chronological age or reading level. Reading was assessed through word and text reading tasks. Error types were classified into seven categories and analyzed.
    UNASSIGNED: A repeated-measure ANOVA showed that children with dyslexia made more guessing errors, particularly visual and morphemic errors, than typically developing children. Moreover, these errors were found at both the single word and sentence levels. These findings suggest that children with dyslexia tend to use a global treatment of words, relying on incomplete information to compensate for their difficulties. The findings have practical implications for pedagogical and therapeutic approaches.

    这项研究旨在研究基于视觉实践的职业治疗(VPOT)计划对发育性阅读障碍(DD)儿童的阅读和运动技能的影响。42名儿童被纳入研究。此外,在VPOT之前,对参与者应用了朗读和阅读理解测试2(ORSRC-2)和Bruininininks-Oseretsky运动能力测试2-简短表格(BOT2-BF)。根据研究设计,VPOT被应用于每周两个疗程,为期8周。在此期间,B组为对照组。在这八周结束时,对两组进行评估测试.然后,A组为对照组,B组为干预组,并将VPOT应用于B组。在另外8周结束时,对两组进行了第三次评估测试.当检查最终的ORSRC-2结果时,VPOT被认为是提高阅读技能的有效计划。此外,当检查最终的BOT2-BF结果时,确定VPOT可有效改善运动技能(p<0.05)。我们认为,重要的是进行全面的研究,例如VPOT计划,以解决DD儿童的身体和学习活动中的问题。
    This study aimed to examine the effects of a visual praxis-based occupational therapy (VPOT) programme on reading and motor skills for children with developmental dyslexia (DD). Forty-two children were included in the study. Additionally, before VPOT, the Reading-Aloud and Reading-Comprehension Test 2 (ORSRC-2) and the Bruininks-Oseretsky Motor-Proficiency-Test-2-Brief Form (BOT2-BF) were applied to the participants. According to the study design, VPOT was applied to two sessions per week for 8 weeks to group A. During this period, group B was accepted as the control group. At the end of these 8 weeks, evaluation tests were applied to both groups. Then, group A was defined as the control group and Group B as the intervention group, and VPOT was applied to Group B. At the end of another 8 weeks, evaluation tests were applied to both groups for the third time. When the final ORSRC-2 results were examined, VPOT was found to be an effective programme for improving reading skills. Additionally, when the final BOT2-BF results were examined, VPOT was determined to be effective in improving motor skills (p < 0.05). We believe that it is important to carry out comprehensive studies such as the VPOT programme to solve problems in the physical and learning activities of children with DD.

    许多研究试图确定阅读障碍的根本原因。不同的阅读障碍理论提出了语音,注意,或视觉缺陷。虽然研究已经使用眼动追踪来研究阅读障碍,之前只有两项研究使用移动窗口范式来探索阅读障碍阅读中的感知跨度,没有人在视觉搜索中这样做。本研究使用阅读和视觉搜索任务分析了感知范围,以识别阅读障碍中与语言无关的注意力障碍。我们发现模棱两可的证据表明,阅读障碍者的感知范围受到损害,而视觉搜索没有损害的证据。然而,阅读障碍参与者确实在视觉搜索任务中表现出缺陷,与对照组相比,搜索精度较低,扫视较短。这些结果为视觉提供了支持,而不是注意力或语音,诵读困难的帐户。
    Many studies have attempted to identify the root cause of dyslexia. Different theories of dyslexia have proposed either a phonological, attentional, or visual deficit. While research has used eye-tracking to study dyslexia, only two previous studies have used the moving-window paradigm to explore the perceptual span in dyslexic reading, and none have done so in visual search. The present study analysed the perceptual span using both reading and visual search tasks to identify language-independent attentional impairments in dyslexics. We found equivocal evidence that the perceptual span was impaired in dyslexic reading and no evidence of impairment in visual search. However, dyslexic participants did show deficits in the visual search task, with lower search accuracy and shorter saccades compared with controls. These results lend support for a visual, rather than attentional or phonological, account of dyslexia.

    通过对一个大型的阅读障碍在线支持小组和一个感官镜头的反身主题分析,这项研究调查了母亲如何通过隐喻来理解孩子的阅读障碍。母亲们用隐喻来描述他们对阅读障碍的感受,他们以学校为基础的互动和他们作为倡导者的身份。母亲使用的语言提供了生成性,有纹理的方式来理解支持孩子学习差异的生活经历。虽然母亲表达了很多沮丧和愤怒,他们还表示鼓励,给予建议,同情和希望,说明了他们的代理意识是如何受到威胁和授权的有一个孩子与阅读障碍的经验。有很多母亲必须处理,了解和导航周围的孩子的阅读障碍和研究结果强调了早期学校筛查的必要性,支持和干预。
    Through a reflexive thematic analysis of a large online support group for dyslexia and a sensemaking lens, this study investigated how mothers made sense of their child\'s dyslexia through metaphors. Mothers used metaphors to characterise their feelings surrounding dyslexia, their school-based interactions and their identity as advocates. The language mothers use offers a generative, textured way to understand the lived experiences of supporting a child with learning differences. Whilst mothers articulated much frustration and anger, they also voiced encouragement, advice-giving, empathy and hope, illustrating how their sense of agency was both threatened and empowered by the experience of having a child with dyslexia. There is much mothers must process, understand and navigate surrounding their child\'s dyslexia and the findings underscore the need for early school-based screening, support and intervention.
