The paper presents results of the neuropsychological assessment of processes involved in the maintenance of activation (Luria’s Unit I functions) in 64 firstgraders who demonstrated various levels of academic success. On the basis of this assessment, the children were divided into three groups: (i) the children without any deficit in the Unit I functions (CONTROL children), (ii) those predominantly showing slowness/fatigue (SLOW children), and (iii) those who can be considered as predominantly hyperactive-impulsive (HYPERACTIVE children). It is shown that, relative to controls, both SLOW and HYPERACTIVE children show reduced academic scores and the decrease of most indices that characterize functions of the Units II and III. The weaknesses of executive and visual-spatial functions are predominantly observed in HYPERACTIVE children, whereas SLOW children usually show some deficit in processing of kinesthetic (proprioceptive) and audio-verbal information. Children with functional weakness of the Unit I functions show an overall reduction in performance and its speed in the computerized versions of the “DOTS” and “SCHULTE—GORBOV tables” tests. In HYPERACTIVE children, deficits are observed in the most difficult tasks (those probing mostly into planning and control functions), and their performance is the most unstable. In SLOW children, the performance rate is noticeably decreased for the moderate-to-difficult tasks. Overall, the data reported contribute to the understanding of the diversity of Unit I functions deficits and their relation to the learning difficulties experienced by children in the primary school.

Actual problem of a modern neuropsychology is elaboration of batteries of tests combining advantages of qualitative and quantitative approaches. In this article we describe an important step of quantitative processing of neuropsychological data in “Method of neuropsychological assessment of children of 6—9 years” the formation of the generalized indices. The described procedure of the statistical analysis of neuropsychological results appreciably reproduces the logic of the expert who is carrying out the qualitative syndrome analysis of HMF-dysfunction. The formation of indices is considered on an example of neuropsychological assessment of 98 elementary school students with learning disabilities and 33 students with autistic disorders. 

This article aims to acquaint the wide community of general and special education teachers, psychologists, speech and language therapists, including those who work in integrative and inclusive environments, with the outlines of child neuropsychology and neuropsychological approach to assessment, prevention, and remediation of learning disabilities. In the last 20 years the field of psychological theory and practice named school neuropsychology which bases itself upon Vygotsky’s and Luria’s ideas has been developing in Russia. It is actively penetrating the psychological and educational practices involving effective research based methods. Unfortunately, many professionals working in educational sphere and even school psychologists are not aware of the goals and methods of this approach to overcoming learning disabilities. This article aims to contribute in closing this gap.
