線引き課題における筆記用具の把持形態と操作性の発達的関係に関する予備的研究

Preliminary study of developmental characteristics of the relation between prehension and manipulation of drawing device during precision drawing tasks

要旨：本研究は，幼児における筆記用具の握り方と操作性の発達的な関連を明らかにすることを目的に，3〜5歳の女児30名に対し，対象児の自発的な握り(自然な握り)と3指握り・4指握り・挟み握り・手掌一回外握りの4つの規定した握りで線引き課題を実施した．操作性に関しては誤数とスピードの2つの視点から分析を行った．その結果，対象児の「自然な握り」や「誤数」については，先行研究と同様に，年齢が高くなるとレベルの高い握りが多くなり，誤数は減少した．さらに，操作性に関する誤数とスピードの関連という視点からは，5歳で誤数は減少するがスピードは遅くなるという新たな知見が得られた．

　The purpose of this study is to reveal that developmental characteristics of the relation between prehension and manipulation of drawing devises in preschool children. 30 girls aged 3, 4, and 5 years old were asked to perform precision drawings each with spontaneous prehension and prescribed four prehensions (tripod grasp, quadripod grasp, finger hold grasp, palmar supinate grasp).

　Manipulativities were analyzed by measuring errors and speeds. The result indicated that, as the age increased, spontaneous prehension tended to show the that maturate grip level and errors decreased, as previously reported. Furthermore, we analyzed drawing speeds and found that they became slower at the age of five.
