ABSTRACT
The learning and development of deaf children also meet obstacles to input and feedback, but these calls for special conditions other than those needed by blind children. Skills are made up of perceptual as well as motor components – input as well as output. For inert children the special conditions needed should ensure that movement and a change in position are accompanied by a change in sensation, and that these changes are repetitive and consistent. Once infants have started to crawl and move around, the next phase of systematic exploration can be prepared by learning to follow set pathways. Mothers usually go quickly to their infants and young children when they cry or call for attention. Physically handicapped children need aids to stability, mobility and communication. Blind children experience obstacles to input and feedback, and they depend on sound for information about events at a distance.
