The main purpose of the research was to assess the level of language development in correlation with mnemonic function in preschool age. A formative psycho-pedagogical experiment was performed. The research involved two categories of preschool children aged between 5 and 7 years: with typical development and language disorders (pronunciation-polymorphic dyslalia). The NEPSY test battery was applied to assess the level of development of neuropsychic functions. The research results demonstrated the existence of statistically significant differences between preschoolers with typical development and preschoolers with polymorphic dyslalia, from the perspective of the investigated psychic levels, respectively language and memory.
