“…The psycholinguistic approach considers speech activity as an integrated unity of linguistic and communication components, and, therefore, enables the most holistic and comprehensive diagnosis of speech disorders and related speech interventions. The specific nature of the development of speech activity in preschoolers has been described by numerous scholars (Behas et al, 2019;Kalmykova, 2009;Leontyev, 1990;Melnyk et al, 2019;Melnyk et al, 2021;Sheremet et al, 2019;Sobotovych, 1997;Vyhotsky, 1983;Zhynkin, 1958;Zimnyaya et al, 1977 and others) who highlight its complex function, polystructuralism, mobility and the relationship between speech activity and all other mental functions. Meanwhile, both Ukrainian (Akhutina et al, 2017;Kalmykova, 2009) and international (Mandak & Light, 2018;Mathisen et al, 2016;Rao, 2011;Wakita, 1976) academics are predominantly guided by linguo-didactic views, which tend to overlook psycholinguistic motivation for the development of speech units that arises from the child's need to communicate.…”
