Co rodzice wiedzą o zasobie słownictwa swoich dzieci? Kwestionariuszowe badanie rozwoju słownika dzieci 2–6-letnich

What do parents know about their children’s vocabulary? A questionnaire/checklist study of lexical development in children aged 2–6The paper presents a study on lexical development of Polish children aged 2–6. Three tools were constructed for this purpose: “The Child Lexicon Development Questionnaire/Checklist”, “The Questionnaire: Communication and Family Routines“ and a personal questionnaire. All were filled in by children’s parents. The first tool comprised nouns, verbs and adjectives drawn in a layered drawing from the Frequency List of Polish Language Corpus (PWN, 2004). The next two consisted of questions related to interactions in the family, social environment and family SES. Data from 148 children were analyzed. Results revealed non-linear lexical growth with age, positive impact of diversified interactions with parents as well as of a number of different games/play situations with peers on children’s vocabulary. Interactions with parents mainly affected noun and adjective vocabulary, while the number of plays with peers affected verb vocabulary.
