Introduction: Incoherence is new concept in psychology. It characterizes the inconsistency in a person's representations of the world, himself and other people. The development of psychodiagnostic tools for assessing incoherence is an actual problem. Objectives: The purpose of this study is the primary approbation of the questionnaire for the assessment of the perception of contradictions. Method: The study involved 26 schizophrenia patients and 15 healthy subjects. Experimental questionnaire "Study of contradictions" includes 39 pairs of opposing or not opposing characteristics of the person (both physical and psychological and social). The subject is asked to answer "YES" or "NO" to questions whether a person can be characterized simultaneously by both characteristics of the pair. The results are processed on 4 scales: physical antonyms (tall and short); physical non-antonyms (high and lightweight); social and psychological antonyms (kind and evil); social and psychological non-antonyms (happy and evil). Results: Most subjects of both groups had no difficulty completing the questionnaire, which indicates the possibility of its use in clinical settings. There were no significant differences between groups on the scale "physical antonyms". But it was found that patients with schizophrenia significantly less likely to coexist in a person's opposite psychological and social characteristics. Also, patients with schizophrenia significantly more often than healthy subjects rejected the possibility of coexistence in humans not opposite characteristics, both physical and psychological and social. Conclusions: The results allow to consider that tolerance of some inconsistency in the perception of themselves and others is a normative phenomenon.
