Characteristics of the Cognitive State Structure of Preschoolers with Brain Lesions

This paper presents a qualitative characteristic of the intellectual states and ways of solving the test tasks according to D. Wechsler’s WPPSI method by children with brain lesions. The analytical data were obtained from a group of 105 preschool children who, according to their scores, were combined into three sample groups: (1) those with borderline state of cognitive development, (2) those with mild cognitive impairment, and (3) those with significant cognitive impairment. Factor analysis revealed a connection between the type of intellectual task and the way of its solution, the nature of brain lesion. The authors determined phenomenological behavior features, confirming the need to adapt the diagnostic procedure for children with organic brain lesions.
