Abstract

<p>二分脊椎症は、先天的に脊椎骨が形成不全となって起こる神経管閉鎖障害の1つであり、脳と脊髄の機能不全により神経学的認知特性を伴う。教科学習においても、これらの認知特性が要因となり、学習上の困難を呈すると思われるが、二分脊椎症児の学習の困難さに焦点を当てた研究は少ない。本研究では、二分脊椎症児12名を対象に、認知特性が算数学習に及ぼす影響について検討を行った。二分脊椎症児の知能検査(WISC-Ⅳ) の指標得点の分析を行った結果、全検査IQは標準の範囲内であるが、知覚推理・処理速度の指標得点の低さが指摘された。また、教研式標準学力検査( CRT)を用いた算数の学習習得状況の把握を行い、WISC-Ⅳの指標得点との相関関係を検討した結果、知覚推理と図形関連の問題の間で正の相関がみられた。これらの結果から、二分脊椎症児の算数学習において、図形や計算等の処理に困難さが見られることが示唆される。</p>

<p>A congenital abnormality, spina bifida is one of the neural tube defects that occurs with vertebral hypoplasia. Children with spina bifida have neurological characteristics of impaired cognitive functions due to brain and spinal cord dysfunctions. Children may have learning difficulties in school due to their cognitive characteristics. However, few studies have focused on the learning dis-abilities in children with spina bifida. In this study, we examined the relationship between chara-cteristics of cognitive functions and arithmetic learning disabilities in children with spina bifida. As a result of the intelligence test (WISC-Ⅳ) which has four indexes. Although the IQ score was within the standard range, the scores of Perceptual Reasoning Index (PRI) and Processing Speed Index (PSI) were low. In addition, we studied the sub-ject's achievement in arithmetic using Criterion Referenced Test (CRT). The results showed that there was a correlation between the index scores of WISC-Ⅳ and CRT and a positive correlation between PRI and graphic questions. These results indicate that processing, such as of figures and cal-culations, is difficult for children with spina bifida.</p>
