INTELLIGENCE INDEXES AND COGNITIVE DIFFER ENTIATION IN JUNIOR SCHOOLCHILDREN

The data on correlation of Wechsler intelligence indices with signal d ifferentiation speed shown by 5 samples of 11-years old schoolchildren are presented. Three interrelated factors influence this correlation: markerness of correlation between different tasks on signal different iation; the degree of intercorrelation of intelligence subtests; the l evel of intelligence development. It is argued that less developed int elligence is characterized by united general level of signals and thei r correlation differentiation. The data obtained are theoretically con sidered to be in accordance with the notion of cognitive structures be ing the carriers of intellectual abilities.
