[The development of expert systems for forensic psychiatric evaluation].

Possible methodological approaches to elaboration of the expert systems in forensic psychiatry are presented. These systems are intended for doubtful "borderline" cases. The comparison of psychopathologic parameters with peculiarities of criminal situation (character of the delinquency, the role of the examined person, other factors) is the base of such approach.

[Refining the definition of dissimulation].

Different approaches to the understanding of the term dissimulation are discussed. It is marked, that dissimulation may be encountered in all forms of pathology beyond the nosological boundaries, but depending upon the socio-personality significance of the disease. The authors propose to consider dissimulation from the clinico-social standpoint and understand it as a limited and changed by pathology personality-modulated behaviour of patients, directed towards preservation (rehabilitation) of a status of a normal individual.
