Expert evaluation criteria for “accumulated” affect in the investigation of violent crimes

Modern forensic expertise requires refined criteria for mental states influencing the volitional and intellectual components of human activity. This study provides a scientific substantiation of expert criteria for cumulative affect within the Complex Forensic Psychological and Psychiatric Examination (CFPPE). The primary objective is to differentiate states of total disorganization in voluntary regulation to ensure uniform interpretation of “sudden onset of strong mental distress” under Articles 101 and 111 of the Criminal Code of the Republic of Kazakhstan. The study’s significance lies in its comprehensive analysis of terminological inconsistencies between general psychology and criminal law. Utilizing a systematic analysis of regulatory acts and international databases (Scopus, PubMed, eLibrary.ru), the research identifies conceptual differences in interpreting affect. The findings justify the necessity for strict determination of expert concepts to ensure legal certainty. Ultimately, this research advances CFPPE methodology by offering approaches to align expert conclusions with Kazakhstani legislation. By clarifying the diagnostic boundaries of cumulative affect, the study supports more accurate judicial qualification of criminal acts, bridging the gap between psychological theory and forensic practice.
