[The functional organization of exploratory activity during feeding and defensive behavior]

The experimental evidence is presented for the proposed hypothesis that searching activity has a heterogeneous functional structure, which includes the motivation-power and cognitive information components. The quantitative characteristics of the first and second constituents are put forward as well as the ways of their determination in appetitive and defensive behavior. It was experimentally demonstrated that the characteristics of searching activity depended on modality and extent of motivation, repetition of searching situation, and sex.
