A significant academic monograph by Academician Revaz Natadze (1903–1984), a founding figure of the renowned Georgian school of psychology and a close collaborator of Dimitri Uznadze. This work represents a culmination of Natadze's extensive experimental research into the psychological theory of "set" (установка) and its relationship to imagination. The book specifically explores how imagined situations can induce behavioral sets, bridging experimental psychology with practical applications, such as stage impersonation according to the Stanislavsky system. Published by the Georgian Academy of Sciences, the volume includes a comprehensive English summary and contents page (notably featuring a charming typographical error on the English title page: "FACTOP" instead of "FACTOR"). This specific copy is highly elevated by a warm, dated presentation inscription from the author written shortly after publication. A pristine, signed artifact of Soviet psychological science, perfect for collectors of academic history and behavioral theory.
