[The peculiarities of defining the psychological and information characteristics of individuals in non-standard situations].

In some situations (e.g. long-duration experiments with human subjects, accidents and catastrophes) assessment of individual's ability to work or even continue functioning by objective criteria may have practical implications. The authors propose complementing the common methods of examination with a number of semantic, self-awareness, associative and symbolic (sign) questionnaires. Thrice-repeated questioning was found to provide adequate results reducing the dispersion of data. The proposed approach was positively validated in an accident and showed good consistency when compared with the objective examination data.
