Study conducted to examine the role of visual imagery in the centripetal execution principle (CEP), which is a graphic rule that is related to the drawing of complex figures composed of embedded geometric shapes. A total of 27 children participated in the study, as they were divided into three groups: (1) sighted (with blindfold), (2) low vision, and (3) blind. The participants explored three raised-line drawings that consisted of four embedded geometric shapes. The children could make out the shapes by touching them with their index fingers, which is called “contour following.” A Swedish raised-line drawing kit was used to make the drawings. The results revealed the dominance of CEP among the children who were sighted and blindfolded, but not in the group with low vision. The authors contend that CEP is not determined by degree of visual acuity, but rather by children’s perceptual experiences. Implications for future research are discussed.
