At the current stage of the development of criminalistics, the knowledge of psychology is becoming integrated into its aspects connected with the tactics of investigatory actions and other procedural aspects of verbal character (interviews, identification, checking testimonies on the spot, etc.), as well as the interaction of all parties in a criminal process, during both pre-trial and court proceedings on a criminal case.
At the same time, scholars do not currently share a common understanding or opinion regarding the structure and contents of such phenomenon as “a contact”, the difference between “psychological contact” and “communicative or emotional contact”, the stages of “establishing a psychological contact”, their borders and criteria determining the contact’s success.
It is necessary to overcome the outlined differences of opinion because crime investigation involves people of various ages and, to establish “a contact” with them, the investigator needs to have not only the knowledge of law, but also of developmental psychology, especially when working with minors and senior citizens.
