Abstract
The article presents the main results of theoretical review on the study of the phenomenon of affect and definition, classification, legal aspects of affective states, as well as the results of statistical processing of data on crimes in the state of affect are provided in Kazakhstan for the last 5 years according to the provided statistical data from the database of the General Prosecutor's Office of the CLSaSA (Committee on Legal Statistics and Special Accounts) of the RK. The relevance of this study is the study of the phenomenon of affect in Kazakhstan, as well as the processing of statistical data on affective suicide, as little-studied and not sufficiently developed phenomena. It is important to note the difference in approaches to understanding the term physiological affects (PA), which actually has no direct analogue in the English-language bibliography. In some respects, the concept of an "irresistible impulse" based on passion corresponds to it. Both conditions can significantly affect a person's behavior and their ability to control their actions, while both can serve as mitigating circumstances in law. At the same time, physiological affect is usually short-lived and characteristic of sane individuals, while an irresistible impulse can be a chronic condition associated with a mental disorder. Subsequent research may be devoted to the issues of comparing the two above concepts from a forensic perspective.
