Summary/Abstract: In this study we have dealt with children in their early ontogenetic period that is suitable for learning achievement. All the children participating in the study had various degrees of visual impairment from partial to complete (congenital) blindness. The left cerebral hemisphere in healthy people is dominant in regard to language function, while the right cerebral hemisphere dominates spatial processing. It was expected that children with visual impairment would benefit from domination of the right cerebral hemisphere when processing language information. It has also been established that success in letter recognition strongly depends on the strategy subjects use to explore the stimuli. Fifteen right-handed children aged 7 to 11 years were divided in three groups according to the degree of visual deficit — partially seeing, slightly blinded, and congenitally blinded. They had to actively touch and explore Cyrillic letters that have different spatial configuration. The results did not prove the predominance of the right cerebral hemisphere in children with visual deficit when processing letter stimulation.
