Rabinovich. [The study of intelligence in deaf-mutes of preschool and school age ]

Abstract:
The formation of intelligence in deaf and dumb children was studied through the study of individual functions. G. Rossolimo`s modified brief method was used here to study ideas about metric and spatial parameters, color perception, time, depth, weight, and volume in 4-year-old children. Among 7—16 year olds, the accuracy of perception, attention, memory, thinking, observation, etc. were studied. It turned out that in a deaf-mute child with normal intelligence, the formation of elementary ideas ends only by 6 years, and in a speaker by 4 years, and ideas about depth, weight and location in deaf-mutes, like talking children, develop last. The use of experimental psychological methods that study individual mental functions is most correct, since when teaching deaf-mutes it is important to establish which mental processes are within the normal range and which are violated. The method of elementary representations is quite applicable to the deaf-mutes and makes it possible to compare them with speakers.
