Tactical-psychological aspect of interaction in the process of communicative investigative actions

In an interrogation, the tactical value lies primarily in those structural elements of the forensic characteristic of the personality of the interrogator that suggest the possibility of effective influence on him or her. The effectiveness of the influence depends on the extent to which the personality traits are receptive to the stimulus contained in the tactical technique. Identifying the personality traits of the interrogator is therefore a necessary part of the interrogator's activity in communicative investigative actions. In order to investigate the ability to intuitively determine psychological properties of a person, a study was carried out. The collected empirical data demonstrates the following performance of psychodiagnostic skills without prior special training. When identifying a personality trait from a pair of polarities, the vector was correctly identified in 96 cases, or just under half (45.7%). Error gradation in quantitative determination of a personality trait is distributed as follows: a small error (up to 10 points) in 63 cases, a medium error (11-20 points) in 22 cases, and a large error (21-30 points) in 5 cases. The analysis of the obtained data allowed us to formulate the following conclusions. Conclusion 1. Interaction in the absence of specific training allows the psychological characteristics of the counterpart's personality to be assessed with 31 to 70 per cent accuracy. Conclusion 2. The effectiveness of tactical interactions is enhanced when directed at a susceptible personality characteristic. A significant error in the identification of psychodiagnostic characteristics based on the mundane level of skill in the tactical plan means the selection of ineffective or even counterproductive tactics. Conclusion 3. A solution to the problem of establishing personality characteristics beyond the habitual perception of the interrogator can be offered in the form of providing a description of the psychological characteristics of the individual. This description can be formulated in the format of a benchmark, psychotypes, parameters. - Benchmark A format for describing a person's characteristics that represents an example of a person who possesses the relevant psychological traits. - Psychotypes a format for describing personality characteristics, which represents mutually exclusive classification groups formed on the basis of psychological properties. - Parameters A format for describing personality characteristics that represents the structural components of a personality (such as processes, states and properties) in quantitative terms. Conclusion 4. Adaptation of borrowed knowledge having criminological value is reasonable to make, firstly, in relation to structure and content of tactical recommendations, secondly, in relation to personal features of the person conducting the criminal investigation, and thirdly, to the personality of the investigator.
