Ocena zasobu słownictwa u dzieci w wieku przedszkolnym – nowe narzędzie testowe

Ewa Haman

Developmental Psychology, Volume 15, Issue 1, 2010, pp. 21-45

The paper presents the first phase of research aimed at the construction of Picture Vocabulary Test (part I – Comprehension; OTS-R). Development of a mental lexicon is one of the basic components of linguistic and communicative competence (Michnick-Golinkoff et al., 2000; Hall and Waxman, 2004). Vocabulary size affects other aspects of language acquisition e.g. grammar (Dale et al., 2000; Dionne et al., 2003). Presented measure aims at the assessing word comprehension in preschool Polish children. In this phase of research, 351 children (age 2–6) took part in the study. Word comprehension was assessed by a picture choice task. Children were presented with a series of four pictures charts, each containing pictures depicting a target word (noun, verb, or adjective) and three distractors related to the target word phonetically, semantically, and thematically. Results show a gradual increase of vocabulary with age, better understanding of verbs over nous and adjectives, and a greater proportion of semantic errors over the other two types of errors. The study enabled the preparation of a new version of assessment tool which is going to be used in the subsequent phase of the research (norming study).

Teoria umysłu i jej pomiar u dzieci w wieku 4–6 lat: Test Refleksji nad Myśleniem

Developmental Psychology, Volume 23, Issue 1, 2018, pp. 41-68

The paper presents Test Refleksji nad Myśleniem (TRM, Reflection on Thinking Test), designed to investigate the development of reflection on thinking in children above 4 years of age. TRM is composed of nine tasks in the form of illustrated stories. The tasks assess child’s understanding of the 1^st order beliefs (Unexpected Transfer Test and Deceptive Box Test), understanding of deception, ambiguity and interpretation, understanding of surprise and the 2^nd order beliefs. In order to evaluate basic psychometric properties of TRM, data gathered from 259 Polish monolingual children aged 4 to 6 were analyzed. The test correctly differentiates the scores of 4-, 5- and 6-year-olds and displays appropriate measurement invariance. The TRM results are positively correlated with results of tests measuring general cognitive and linguistic abilities in children. Additionally, in accordance with our predictions, the typically developing children obtained significantly higher results than children with specific language impairment. The results confirm that TRM is a reliable and valid instrument that can be used in basic research.

Developmental Psychology, Volume 14, Issue 2, 2009, pp. 57-71

The 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.
