    New forms of interaction made possible by developments in special educational technologies can now help students with dyscalculia. Artificial intelligence (AI) has emerged as a promising tool in recent decades, particularly between 2001 and 2010, offering avenues to enhance the quality of education for individuals with dyscalculia. Therefore, the implementation of AI becomes crucial in addressing the needs of students with dyscalculia. Content analysis techniques were used to examine the literature covering the influence of AI on dyscalculia and its potential to assist instructors in promoting education for individuals with dyscalculia. The study sought to create a foundation for a more inclusive dyscalculia education in the future through in-depth studies. AI integration has had a big impact on educational institutions as well as people who struggle with dyscalculia. This paper highlights the importance of AI in improving the educational outcomes of students affected by dyscalculia.

    阅读障碍是一种神经系统疾病,影响个人的语言处理能力。早期护理和干预可以帮助阅读障碍者在学术和社会上取得成功。深度学习(DL)方法的最新发展促使研究人员建立阅读障碍检测模型(DDM)。DL方法促进了多模态数据的集成。然而,很少有基于多模态的DDM。
    在这项研究中,作者使用多模态数据构建了基于DL的DDM。挤压和激励(SE)集成的MobileNetV3模型,基于自我注意机制(SA)的EfficientNetB7模型,并开发了早期停止和基于SA的双向长短期记忆(Bi-LSTM)模型,以从磁共振成像(MRI)中提取特征,功能性MRI,和脑电图(EEG)数据。此外,作者使用Hyperband优化技术对LightGBM模型进行了微调,以使用提取的特征检测阅读障碍。包含FMRI的三个数据集,MRI,和EEG数据用于评估拟议的DDM的性能。
    这些发现支持了拟议的DDM在有限的计算资源下检测阅读障碍的重要性。所提出的模型优于现有的DDM,产生98.9%的最佳精度,98.6%,功能磁共振成像占98.8%,MRI,和EEG数据集,分别。医疗中心和教育机构可以从所提出的模型中受益,以在初始阶段识别阅读障碍。通过集成基于视觉变换器的特征提取,可以提高所提出模型的可解释性。
    UNASSIGNED: Dyslexia is a neurological disorder that affects an individual\'s language processing abilities. Early care and intervention can help dyslexic individuals succeed academically and socially. Recent developments in deep learning (DL) approaches motivate researchers to build dyslexia detection models (DDMs). DL approaches facilitate the integration of multi-modality data. However, there are few multi-modality-based DDMs.
    UNASSIGNED: In this study, the authors built a DL-based DDM using multi-modality data. A squeeze and excitation (SE) integrated MobileNet V3 model, self-attention mechanisms (SA) based EfficientNet B7 model, and early stopping and SA-based Bi-directional long short-term memory (Bi-LSTM) models were developed to extract features from magnetic resonance imaging (MRI), functional MRI, and electroencephalography (EEG) data. In addition, the authors fine-tuned the LightGBM model using the Hyperband optimization technique to detect dyslexia using the extracted features. Three datasets containing FMRI, MRI, and EEG data were used to evaluate the performance of the proposed DDM.
    UNASSIGNED: The findings supported the significance of the proposed DDM in detecting dyslexia with limited computational resources. The proposed model outperformed the existing DDMs by producing an optimal accuracy of 98.9%, 98.6%, and 98.8% for the FMRI, MRI, and EEG datasets, respectively. Healthcare centers and educational institutions can benefit from the proposed model to identify dyslexia in the initial stages. The interpretability of the proposed model can be improved by integrating vision transformers-based feature extraction.

    有诵读困难的人,阅读的神经发育障碍,高度适应情感世界。与他们典型的发展中同行相比,患有阅读障碍的儿童表现出更大的自主神经系统反应性和面部行为,以引起情感和同理心的电影剪辑。情感症状,比如焦虑,在有阅读障碍的儿童中也比没有阅读障碍的儿童更常见。这里,我们调查了惊吓反应,情绪和反射的界面上的自动反应,在阅读障碍中升高。我们测量了面部行为,皮肤电反应性(交感神经系统测量)和对100毫秒的反应的情绪体验,在30名阅读障碍儿童和20名没有阅读障碍的比较儿童(7-13岁)中,有105dB意外的声学惊吓任务,性和非语言推理。我们的结果表明,与没有诵读困难的儿童相比,有诵读困难的儿童具有更高的整体面部行为和对听觉惊吓任务的皮肤电反应性。在整个样本中,惊吓期间皮肤电反应性越大,父母报告的焦虑症状就越大.这些发现有助于阅读障碍的情绪反应性增强,并表明交感神经系统反应性增强可能导致该人群中经常出现的焦虑升高。
    People with dyslexia, a neurodevelopmental disorder of reading, are highly attuned to the emotional world. Compared with their typically developing peers, children with dyslexia exhibit greater autonomic nervous system reactivity and facial behaviour to emotion- and empathy-inducing film clips. Affective symptoms, such as anxiety, are also more common in children with dyslexia than in those without. Here, we investigated whether the startle response, an automatic reaction that lies at the interface of emotion and reflex, is elevated in dyslexia. We measured facial behaviour, electrodermal reactivity (a sympathetic nervous system measure) and emotional experience in response to a 100 ms, 105 dB unanticipated acoustic startle task in 30 children with dyslexia and 20 comparison children without dyslexia (aged 7-13) who were matched on age, sex and nonverbal reasoning. Our results indicated that the children with dyslexia had greater total facial behaviour and electrodermal reactivity to the acoustic startle task than the children without dyslexia. Across the sample, greater electrodermal reactivity during the startle predicted greater parent-reported anxiety symptoms. These findings contribute to an emerging picture of heightened emotional reactivity in dyslexia and suggest accentuated sympathetic nervous system reactivity may contribute to the elevated anxiety that is often seen in this population.

    据作者所知,本文是阿尔巴尼亚和邻国首次通过认知行为疗法研究变革性协同干预方法,亲子互动疗法(PCIT),对患有注意力缺陷/多动障碍(ADHD)和并存的对立反抗障碍(ODD)和阅读障碍的儿童进行重金属排毒。阿尔巴尼亚的心理健康意识有限,特别是关于PCIT和类似的治疗,强调了此类干预措施的适用性和适应性的重要性。这项研究表明,多动症合并症的快速管理,比如ODD和阅读障碍,通过联合干预方法和调查生物学方面更好地实现。需要进行大样本量的进一步研究,以评估这种方法的长期可持续性和可扩展性。
    To the best of the authors\' knowledge, this article is the first of its kind in Albania and neighboring countries to investigate the transformative synergistic intervention approach through cognitive behavioral therapy, parent-child interaction therapy (PCIT), and heavy metal detoxification on a child with attention-deficit/hyperactivity disorder (ADHD) and comorbid oppositional defiant disorder (ODD) and dyslexia. The limited mental health awareness in Albania, particularly regarding PCIT and similar treatments, highlights the importance of the applicability and adaptability of such interventions. This study suggests that the rapid management of comorbidities in ADHD, such as ODD and dyslexia, is better achieved by a combined intervention approach and by investigating the biological aspects. Further research with a large sample size is needed to assess the long-term sustainability and scalability of such an approach.

    儿童的阅读进度通常在正规教育的长时间休息期间减慢,比如暑假。对于有阅读困难或残疾的儿童来说,这种停滞尤其令人担忧。比如诵读困难,因为有可能加剧他们和同龄人之间的技能差距。阅读干预可以防止技能损失,甚至在夏季带来阅读能力的可观提升。将干预反应与大脑变化相关的纵向研究可以揭示对快速学习驱动的大脑可塑性的教育相关见解。目前的工作重点是阅读结果和白质连接,这使得熟练阅读所需的大脑区域之间能够进行交流。我们在夏初和夏末收集了41名一年级或二年级阅读困难儿童的阅读分数和扩散加权图像。儿童被随机分配接受强化阅读干预(n=26;从Lindamood-Bell看到星星,强调拼字流畅)或被推迟到等待名单组(n=15),使我们能够分析白质属性如何在广泛的技能发展和回归轨迹中变化。平均而言,与非干预组相比,干预组的阅读增益更大,他拒绝阅读分数。改善了近端测量的正交处理(而不是其他更多的远端阅读测量)与核心阅读大脑回路(左弓形束和左下纵向束)内的平均扩散率降低以及左皮质脊髓束的分数各向异性增加有关。我们的发现表明,对强化阅读教学的反应主要与与阅读最相关的领域中的白质可塑性有关。
    Children\'s reading progress typically slows during extended breaks in formal education, such as summer vacations. This stagnation can be especially concerning for children with reading difficulties or disabilities, such as dyslexia, because of the potential to exacerbate the skills gap between them and their peers. Reading interventions can prevent skill loss and even lead to appreciable gains in reading ability during the summer. Longitudinal studies relating intervention response to brain changes can reveal educationally relevant insights into rapid learning-driven brain plasticity. The current work focused on reading outcomes and white matter connections, which enable communication among the brain regions required for proficient reading. We collected reading scores and diffusion-weighted images at the beginning and end of summer for 41 children with reading difficulties who had completed either 1st or 2nd grade. Children were randomly assigned to either receive an intensive reading intervention (n = 26; Seeing Stars from Lindamood-Bell which emphasizes orthographic fluency) or be deferred to a wait-list group (n = 15), enabling us to analyze how white matter properties varied across a wide spectrum of skill development and regression trajectories. On average, the intervention group had larger gains in reading compared to the non-intervention group, who declined in reading scores. Improvements on a proximal measure of orthographic processing (but not other more distal reading measures) were associated with decreases in mean diffusivity within core reading brain circuitry (left arcuate fasciculus and left inferior longitudinal fasciculus) and increases in fractional anisotropy in the left corticospinal tract. Our findings suggest that responses to intensive reading instruction are related predominantly to white matter plasticity in tracts most associated with reading.

    阅读障碍,获得熟练阅读的特定困难,其特征还在于短期记忆(STM)容量降低。广泛的研究表明,患有发展性阅读障碍(IDD)的人从暴露中受益较少,这阻碍了他们长期的知识积累。众所周知,长期知识对STM任务的性能有很大影响,因此,IDD暴露的好处减少可能会降低它们在此类任务中的相对性能,特别是当频繁的项目,如数字字,使用。在这项研究中,我们使用了一个标准,广泛使用,STM评估:韦氏成人智力量表的数字跨度分测验。该任务进行了两次:母语和第二语言。因为接触母语大于接触第二语言,我们预测,与第二语言相比,IDDs在以母语管理的任务中的表现将显示出更大的群体差异,由于IDD\'减少了项目频率的好处。预测得到了证实,与以下假设一致:阅读障碍中STM的减少在很大程度上反映了长期项目频率的减少,而不是STM本身的减少。
    Dyslexia, a specific difficulty in acquiring proficient reading, is also characterized by reduced short-term memory (STM) capacity. Extensive research indicates that individuals with developmental dyslexia (IDDs) benefit less from exposure, and this hampers their long-term knowledge accumulation. It is well established that long-term knowledge has a great effect on performance in STM tasks, and thus IDDs\' reduced benefit of exposure could potentially reduce their relative performance in such tasks, especially when frequent items, such as digit-words, are used. In this study we used a standard, widely used, STM assessment: the Digit Span subtest from the Wechsler Adult Intelligence Scale. The task was conducted twice: in native language and in second language. As exposure to native language is greater than exposure to second language, we predicted that IDDs\' performance in the task administered in native language will reveal a larger group difference as compared to second language, due to IDDs\' reduced benefit of item frequency. The prediction was confirmed, in line with the hypothesis that reduced STM in dyslexia to a large extent reflects reduced benefits from long-term item frequency and not a reduced STM per se.

    参与认知功能的神经过程的电活动被捕获在EEG信号中,允许探索跨多个时空尺度的神经元振荡的整合和协调。我们提出了一种新颖的方法,将EEG信号转换为图像序列,考虑涉及低级听觉处理的交叉频率相位同步(CFS)动力学,随着用于检测发展性阅读障碍(DD)的两阶段深度学习模型的发展。这种深度学习模型利用图像序列中保存的空间和时间信息来发现相位同步随时间变化的判别模式,达到高达83%的平衡精度。该结果支持了典型和诵读困难的7岁读者之间存在差异的大脑同步动力学。此外,我们使用一种新的特征掩模获得了可解释的表示,将分类过程中最相关的区域与正常阅读的认知过程以及与阅读障碍中发现的代偿机制相对应的认知过程联系起来.
    The electrical activity of the neural processes involved in cognitive functions is captured in EEG signals, allowing the exploration of the integration and coordination of neuronal oscillations across multiple spatiotemporal scales. We have proposed a novel approach that combines the transformation of EEG signal into image sequences, considering cross-frequency phase synchronisation (CFS) dynamics involved in low-level auditory processing, with the development of a two-stage deep learning model for the detection of developmental dyslexia (DD). This deep learning model exploits spatial and temporal information preserved in the image sequences to find discriminative patterns of phase synchronisation over time achieving a balanced accuracy of up to 83%. This result supports the existence of differential brain synchronisation dynamics between typical and dyslexic seven-year-old readers. Furthermore, we have obtained interpretable representations using a novel feature mask to link the most relevant regions during classification with the cognitive processes attributed to normal reading and those corresponding to compensatory mechanisms found in dyslexia.

    本文旨在帮助从业者理解阅读障碍和其他阅读困难,并评估学生的学习需求。我们描述了语言和识字的基本组成部分,通用筛查,诊断评估,基于课程的测量和资格确定。然后我们介绍四个诊断评估作为例子,包括规范参考的评估(即第二版语音处理综合测试和Woodcock-JohnsonIV成就测试)和标准参考的评估(即编码技能的Gallistel-Ellis测试和基本早期识字技能的动态指标)。最后,我们使用一个化妆案例作为一个具体的例子来说明如何记录多个诊断评估,以及如何使用结果来告知干预和特殊教育服务的资格。
    This article aims to assist practitioners in understanding dyslexia and other reading difficulties and assessing students\' learning needs. We describe the essential components of language and literacy, universal screening, diagnostic assessments, curriculum-based measurement and eligibility determination. We then introduce four diagnostic assessments as examples, including norm-referenced assessments (i.e. the Comprehensive Test of Phonological Processing second edition and the Woodcock-Johnson IV Tests of Achievement) and criterion-referenced assessments (i.e. the Gallistel-Ellis Test of Coding Skills and the Dynamic Indicators of Basic Early Literacy Skills). Finally, We use a makeup case as a concrete example to illustrate how multiple diagnostic assessments are recorded and how the results can be used to inform intervention and eligibility for special education services.

    这项研究的目的是探索发育性计算障碍儿童的许多感觉缺陷,诵读困难,共同发生的疾病和他们典型的发展中的同龄人。在这项研究中使用了非符号数量比较任务来检查患有计算障碍的儿童是否有数字感觉缺陷。塔伊夫市九所小学10-11岁的儿童,沙特阿拉伯,被选中参加这项研究。将儿童分为计算障碍组(n=62),阅读障碍组(n=60),和共发障碍组(n=65),和典型发展中的同龄人组(n=100)。4组(计算障碍,诵读困难,共同发生的疾病和典型的发展同龄人组)×2刺激比(6:7;8:12)。阅读障碍儿童之间的非符号数量比较任务存在显着差异,同时发生的疾病,通常是发展中的同行。这些结果表明,患有计算障碍的儿童确实存在数字感觉缺陷,但是数字感知缺陷并不局限于患有计算障碍的儿童。
    The aim of this study was to explore a number sense deficits in children with developmental dyscalculia, dyslexia, co-occurring disorder and their typically developing peers. A non-symbolic quantity comparison task was used in this study to examine whether children with dyscalculia have number sense deficits. Children aged 10-11 years old from nine primary schools in Taif city, Saudi Arabia, were selected to participate in this study. The children were divided into the dyscalculia group (n = 62), the dyslexia group (n = 60), and co-occurring disorder group (n = 65), and the typically developing peers group (n = 100).4 groups (dyscalculia, dyslexia, co-occurring disorder and typically developing peers group) × 2 stimulus ratio (6:7; 8:12). There were significant differences in non-symbolic quantity comparison tasks between children with dyslexia, co-occurring disorder, and typically developing peers. These results indicate that children with dyscalculia do have number sense deficiencies, but number sense deficiencies are not specific to children with dyscalculia.

    尽管关于父母教养方式与神经发育障碍之间关系的研究越来越多,人们很少关注父母教养方式如何影响孩子的阅读能力。这项研究的目的是调查家庭识字环境在父母教养方式与阅读障碍之间的潜在中介作用。
    本研究共招募了212名2-5年级的小学生。中文阅读能力测试用于筛查阅读障碍儿童。使用结构化问卷评估了家庭识字环境,该问卷测量了父母与子女之间与阅读相关的活动的频率和质量。EgnaMinnenBeträffandeUppfostran问卷用于评估父母的养育方式,包括情感上的温暖,拒绝,过度保护,和焦虑的养育。这是一个由孩子们自己填写的自我报告工具,用来评估他们对父母教养方式的看法。进行了结构方程建模,以评估直接,间接,以及父母教养方式对阅读障碍的总体影响。
    与对照组相比,患有阅读障碍的男性儿童在以情感温暖为特征的父母教养方式上得分较低,过度保护和焦虑养育(p<0.05),而患有阅读障碍的女性儿童仅在焦虑养育方面得分较低(p<0.05)。阅读障碍儿童缺乏规律阅读时间(OR=2.69,95CI:1.04-6.97,p<0.05),与正常儿童相比,作业压力更高(OR=7.41,95CI:1.45-37.82,p<0.05)。此外,情感温暖,父系过度保护和焦虑养育与儿童阅读障碍呈负相关(均p<0.05)。我们的发现表明阅读障碍之间有很强的相关性,家庭识字环境,和育儿方式。在结构方程模型中,家庭识字环境被认为是父母教养方式和阅读障碍之间的独立中介。父母教养方式对阅读障碍的总影响为0.55,由家庭识字环境介导的间接影响为0.68。
    这项研究的结果表明,家庭识字环境是育儿方式与儿童阅读障碍之间的媒介。这项研究强调了父母教养方式如何影响阅读障碍,为帮助阅读障碍儿童提供关键见解,并指导有效的干预措施。
    UNASSIGNED: Despite an increasing amount of research on the relationship between parenting styles and neurodevelopmental disorders, there has been minimal focus on how parenting styles impact children\'s reading abilities. The aim of this study was to investigate the potential mediating role of the home literacy environment in the connection between parenting styles and dyslexia.
    UNASSIGNED: A total of 212 primary school students from grade 2-5 were recruited for this study. The Chinese Reading Ability Test was used to screen children with dyslexia. The home literacy environment was evaluated using a structured questionnaire that measured the frequency and quality of reading-related activities between parents and children. Egna Minnen Beträffande Uppfostran questionnaire was used to assess the parenting style, including emotional warmth, rejection, overprotection, and anxious rearing. It is a self-report tool filled out by the children themselves, used to assess their perceptions of their parents\' parenting styles. The structural equation modeling was carried out to evaluate the direct, indirect, and total effects of parenting styles on dyslexia.
    UNASSIGNED: Compared to control group, male children with dyslexia had lower scores in parenting styles characterized by emotional warmth, overprotecting and anxious rearing (p < 0.05), while female children with dyslexia only showed lower scores in anxious rearing (p < 0.05). Children with dyslexia lacked regular reading time (OR = 2.69, 95%CI: 1.04-6.97, p < 0.05), and have higher homework pressure compared to normal children (OR = 7.41, 95%CI: 1.45-37.82, p < 0.05). Additionally, emotional warmth, paternal overprotection and anxious rearing were negatively associated with dyslexia in children (all p < 0.05). Our findings indicate a strong correlation between dyslexia, home literacy environment, and parenting styles. In a structural equation model, the home literacy environment was identified as an independent mediator between parenting styles and dyslexia. The total effect of parenting styles on dyslexia is 0.55, with an indirect effect of 0.68 mediated by the home literacy environment.
    UNASSIGNED: The findings of this study indicate that home literacy environment serves as a mediator between parenting styles and dyslexia in children. This study highlights how parenting styles influence dyslexia, offering key insights for aiding dyslexic children and guiding effective interventions.
