Efficiency of voluntary auditory-speech memory in younger schoolchildren with different types of dysontogenesis

INTRODUCTION: Assessing of voluntary auditory verbal memory, mediated or non-mediated by meaning context is an important component of impaired mental or psychic development estimation in children with different types of dysontogenesis. OBJECTIVES: Investigation of memory in chidren with mental disorders METHODS: Participants: Children 9-12 years: ND - 25 normal development (14 boys), F70 - 31 with mild mental retardation (18 boys), F20.8 - 15 children with childhood type of schizophrenia (11 boys) and F21- 29 with schizotypal disorder (22 boys). Learning of 10 words, simple (SPA) and complex (CPA) paired associations. Assessing Parameter - auditory-speech memory efficiency in each of techniques. Mann-Whitney criterion. RESULTS: There were significant differences in memory efficiency of 10 words between F21 and F70 (p≤0.01) and F70 and F20.8 (p≤0.05). Simple paired associations - no differences between all groups. Complex paired associations: F21 and F70 (p≤0.05), F21 and F20.8 (p≤0.01). ND - significant differences in memory efficiency of 10 words with all groups (F21 – p ≤0.01, F20.8 – p ≤0.05, F70 – p ≤0.01). SPA: significant differences with all groups (p≤ 0.01). CPA - significant differences words with all groups (F21 – p≤ 0.05, F20.8 – p≤ 0.01, F70 – p ≤0.01). CONCLUSIONS: Сommon features of working memory in children with diseased type of development:- improved memorization with introduction of strong semantic connections for all types of dysontogenesis. For complex connections in different groups we suppose different mechanisms of destroyed memory: F70 - low level of thinking, F20.8 - decreasing in mental activity or as a result of forming defect. DISCLOSURE: No significant relationships.
