is part of the complex Interpersonal Diagnosis of Personality test, a diagnostic test that was developed in the 1950s by the Kaiser Foundation project under the leadership of American psychologist Timothy Leary. The task of the test is to study a person’s ideas about himself and determine the prevailing type of relationships with other people. To present the results, a psychogram was developed in the form of a circle divided into sectors – octants, each of which reflects a certain type of relationship. At the same time, the horizontal and vertical axes correspond to the main orientations: dominance/submission and friendliness/hostility. The test has been translated into many languages, so in Russia an adapted and modified version is used, developed in the 1970s by the Soviet psychologist Lyudmila Nikolaevna Sobchik.
