Abstract
The paper aims to analysis of relationship between internal and external factors influencing subjects’ cognitive test performance and development of the technique to build possible adaptive individual “norm” to the cognitive test performance. The study confirms our hypothesis that human cognitive performance, at least, with simple and repetitive tasks (that are a part of learning process), can be optimized for assessment and prediction of the productive indicators in normal (without time pressure) and under conditions of limited time for task performance using multiple regression models, if to use indices of both physiological support and space-related factors. Subjective psychological indices can be applied as well, but mostly in relation to young people rather than to adults. We believe that such models describe balance during cognitive performance as measured individual adaptive “norm”, where the latter can be associated with average productivity over time intervals measured in weeks.
