A Developmental Explanation For Children’s Motor behavior

Abstract

Two experiments were conducted to test the application of Pascual-Leone’s (1970) neo-Piagetian theory for explaining children’s acquisition of skill in a curvilinear positioning task. Two groups of children (late pre-operational 6 yr olds and early concrete 8 yr olds) were identified and from each group 10 low M-processors and 10 high M-processors were selected (total n=40) through use of the Children’s Embedded Figures Test. The 6 yr olds were administered 2-and 3-scheme curvilinear positioning tasks while the 8 yr olds performed 3-and 4-scheme tasks. The difference between the two experiments was the nature of the positioning tasks, i.e., one task allowed visual processing of information, while the other did not. Both experiments supported the neo-Piagetian predictions of structural mental space as explaining the developmental nature of motor skill acquisition, and functional mental space as explaining individual differences within stages in children’s performance.
