Development of questions in schoolchildren

The aim of the study was to reveal basic trends in appearance of questions in children, and to establish corresponding factors. Questions were regarded, on the one hand, as a form of speech and, on the other hand, as a form of thinking and cognition of the world. Two categories of questions - cognitive and social-communicative have been particularly analyzed in relation to their adress (an age-mate or a grown-up) and the frequency of occurence.
