Objective: To investigate the development of visual object recognition in primary school children.
Materials and Methods: the investigation involved 22 individuals (11 boys and 11 girls), students of the first year of the Tambov primary school. To identify the cerebral dysfunctions, the following methods were used: the Toulouse-Pieron test, the method of N.Pylaeva for assessment of visual object recognition functions, the method of T. Akhutina and others. Visual object recognition functions were assessed in children with normal psychical development and those with minimal cerebral dysfunctions. Children from the second group performed such neuropsychological tasks as retelling and identification of images.
Results: two-thirds of participants had normal psychical development while one-third had minimal cerebral dysfunctions. These dysfunctions included high fatigability, instability, a periodic slowdown of intellectual activity, an interference of activity from previous on the subsequent one, weak concentration and the complete absence of its distribution, a small amount of short-term and operational memory. The results of the «programming and control» tasks and the «grammar» tasks indicate that children with minimal cerebral dysfunctions cannot fully retell the text, represent the details in the right order, cannot highlight critical points in the text. Such children are usually distracted by minor details and cannot give a summary of what they have read.
Conclusions: the obtained results showed the differences in the cortical mechanisms of visual information processing in children with normal mental development and children with signs of minimal cerebral dysfunction. Insufficient development of such components as programming and control, serial organization, a flexible coupling of an analytical and holistic strategy of perception in children with minimal cerebral dysfunction indicates organic changes in the central nervous system, entailing the formation of disturbances in the data components of visual-verbal functions.
