In this study we investigated the differences of intelligence among younger schoolchildren with different academic achievement.
In this study participated 161 younger schoolchildren. We used WISC. In assessing academic achievements three indicators of academic success were considered (average score in language and mathematics, average score in all subjects, reading skills). According to these indicators we divided the sample into 3 groups: successful, medium and unsuccessful. These groups were compared on indicators of Wechsler's subtests. The significance of differences was tested with Student's T-test.
Academically successful students compared with medium and unsuccessful groups have significant differences on indicators of almost all Wechsler's subtests (except Coding B and Mazes). In other words, successful students have the specific differences, such as latitude of cognitive processes, greater degree of development of conceptual thinking, ability to abstract, classify et al.*The study was supported by RSF grant (project 14-28-00087), Institute of Psychology RAS.
