Exploratory procedures of tactile images in visually impaired and blindfolded sighted children: How they relate to their consequent performance in drawing

Abstract

The aim of the present study was to compare the types of exploratory procedures employed by children when exploring bidimensional tactile patterns and correlate the use of these procedures with the children's shape drawing performance. 18 early blind children, 20 children with low vision and 24 age-matched blindfolded sighted children aged approximately 7 or 11 years were included in the study. The children with a visual handicap outperformed the sighted children in terms of haptic exploration and did not produce less recognizable drawings than their sighted counterparts. Close relationships were identified between the types of exploratory procedures employed by the children and their subsequent drawing performance, regardless of visual status. This close link between action and perception in the haptic modality indicates the importance of training blind children in exploratory procedures at an early age.
