Methods of studying the process of identification used in the psychology abroad are reviewed. Two groups of methods are established. One, which includes observation, rating of behavior, and questioning, is mainly used with preschoolers and younger schoolchildren. The second one, which includes standardized questionnaires, semantic differential scales, and personality construct procedures, is used with older children (12 years and older) and is aimed at establishing the perceived similarity. Limited nature of corresponding studies - as a result of understanding the identification as a mechanism of acquisition of the role behavior - is shown and analyzed by the author.
