Investigated the relationship between the development of logical schemes or operations and the development of total, fine, bilateral and gross motor schemes. The relationship between scheme coordinating ability and motor schemes development and between scheme coordinating ability and logical scheme development was also examined. Logical schemes or operations were measured by Piaget's conservation and chemical tasks and motor schemes were measured by the Bruininks-Oseretsky Test of Motor Proficiency. The ability to coordinate both motor and cogntive schemes was represented by Pascual-Leone's neo-Piagetian construct central computing space which was measured by the Compound Stimulus Visual Information Task (CSVI). A supplemental analysis looked at the relationship of field dependency and logical scheme development. There were 66 subjects divided into three age groups: 4 1/2-6 years, 7-9 years, and 10-12 years. Subjects were not separated by sex as sex differences on cognitive and motor variables were insignificant. Subjects were grouped by Piagetian substage and scheme coordinating power. The analysis included correlations controlling for age and group comparisons. Correlational data revealed significant relationships between logical schemes, motor schemes, and scheme coordinating ability.
