Abstract:
Graphophonological-semantic flexibility is the cognitive flexibility in reading that enables individuals to manage multiple phonological and semantic aspects of text simultaneously. This study investigated graphophonological-semantic flexibility and its contribution to reading comprehension in children with dyslexia, comparing them to age-matched, typically developing peers. Thirty children aged 8-11 were assessed using a reading-specific sorting task, where they categorized word cards by initial phoneme and meaning within a 2x2 matrix. After sorting, participants explained their arrangements, and their sorting speed, accuracy, and composite scores were evaluated. Additionally, reading comprehension was assessed through passages followed by questions. Results revealed significant differences between children with dyslexia and their peers in sorting accuracy and composite scores. Children with dyslexia exhibited poorer accuracy and longer sorting times, leading to lower composite scores indicative of reduced graphophonological-semantic flexibility. Age showed a positive correlation with sorting accuracy and composite scores. Moreover, sorting accuracy and composite scores were strong predictors of reading comprehension. These findings suggest that children with dyslexia face challenges in managing both phonological and semantic aspects of text concurrently, highlighting the importance of graphophonological-semantic flexibility in reading development.
摘要:
图形学语义灵活性是阅读中的认知灵活性,使个人能够同时管理文本的多个语音和语义方面。这项研究调查了阅读障碍儿童的语言语义灵活性及其对阅读理解的贡献,将它们与年龄匹配的比较,通常是发展中的同行。30名8-11岁的儿童使用特定阅读分类任务进行了评估,他们在2x2矩阵中按初始音素和含义对单词卡进行分类。排序后,参与者解释了他们的安排,和它们的分拣速度,准确度,并对综合评分进行评价。此外,阅读理解能力是通过段落和问题进行评估的。结果显示,阅读障碍儿童与同龄人在分类准确性和综合得分方面存在显着差异。患有阅读障碍的儿童表现出更差的准确性和更长的分类时间,导致较低的综合得分,表明字词语义灵活性降低。年龄与排序精度和综合得分呈正相关。此外,排序准确性和综合分数是阅读理解的强预测因子。这些发现表明,阅读障碍儿童在同时管理文本的语音和语义方面面临挑战,强调字词语义灵活性在阅读发展中的重要性。
