Inquisitive activity in the form of questions in different age periods

Results of an experimental study of the verbal inquisitive activity (questions concerning pictorial material) in pre-schoolers, schoolchildren, and adults are presented. Attention has been basically given to the appearance of the orientational function of questions, i. e. of the ability on the part of a child to put questions concerning unknown elements in the pictured problem situation with the intention to break the problem down, to study it and to restrict the scope of search for an answer. Some sensitive periods in the development of the ability have been established (between 6-7 and 8-9, and between 11-12 and 14-15 years for different aspects of questions), as well as some qualitative peculiarities and trends.
