Piaget's theory of stage structure is synonymous with discussions involving cognitive development. As with any theoretical model, researchers inevitably and rightly seek to affirm and/or contest the elements of the model presented. In this comparative study, students' performance across three hands-on engineering tasks for two distinct student…

We examine the contributions of dynamic systems theory to the field of cognitive development, focusing on modeling using dynamic neural fields. After introducing central concepts of dynamic field theory (DFT), we probe empirical predictions and findings around two examples--the DFT of infant perseverative reaching that explains Piaget's A-not-B…

Tested the hypothesis that some attempts to reduce the performance demands of concrete Piagetian operational tasks may have allowed children to solve those tasks with preoperational functions. Administered two previously used versions of the transitivity task for length and weight to 120 children six- to nine-years-old. The second version was…

Whether or not the spatial cognitive development of students from distinct social-cultural milieus, specifically Anglos from the southwestern part of the United States and Native Turks, would proceed along approximately the same lines was investigated. The overall findings tend to indicate that at times the acquisition of spatial structures may be…

Reviews research about young childrens' focusing on the ability to transform a perceived scene into another representation. Reports on a study of 109 children and 18 college-age students on their ability to mold a lump of clay into a three-dimensional figure. Finds that cognitive maturity alone does not automatically lead to competence. (CFR)

Responds to Claire Golumb's research on the cognitive development of young children's ability to create representations of reality using visual arts. Asserts that young children must find acceptable pictorial substitutes when producing representations. (CFR)
