Jackson, J. P. (1974). The relationship between the development of gestural imagery and the development of graphic imagery. Child Development, 45, 432-438.
Children, aged 5, 8, and 11 years, were tested to assess the conformity of their developing symbolic gestural abilities to imagery processes espoused by Piaget (Piaget & Inhelder 1971). A stagelike occurrence of symbolic gestures with transformational properties occurred between ages 8 and 11. However, no correspondence between Piaget's tasks of graphic imagery and the gestural tasks was found, in part because of the lack of ability to replicate Piaget's stages of imagery. Finally, the ability to represent action sequences with symbolic gestures was found to increase for 5- and 8-year-olds under conditions of cue absence. Results are discussed in terms of task requirements and difficulties in Piaget's conception of stages in imagery development.
