Perception of scientific notions and illustrations as a function of organization of the scientific text.
(RESUME)

Some logical-psychological ways of organizing definitions of notions and illustrations in an instructional book, and corresponding outcomes of comprehending them under conditions of spontaneous (non-directed) reading of such texts, are considered. More efficient ways of dealing with problems of designing manuals and text-books based on psychological regularities of perception and comprehension by learners of the instructional material are suggested.
