[Solution of visual and verbal tasks in 5--8-year-old children].

Age and sexual differences in the quality of processing visual and verbal complex signals of different complexity were studied in two groups of 5 to 6 and 7 to 8 years old children (30 children in each). Five to six year old children are able to correctly process only simple signal complexes, the quality of processing more perfect in boys. At the age of seven, the quality of solving problems consisting of complex signals, considerably improves, which is linked to the development of the dominating role of the second signal system. Girls process more successfully visual signals, boys--verbal ones. Three stages are assumed in the development of mental processes involved in the solution of problems consisting of signal complexes.
