[Significance of the cognitive context in formation of unconscious visual sets].

The experimental evidence that the cognitive set shifting in healthy humans depends on the context of cognitive performance is discussed. Lability/rigidity of the experimentally formed unconscious visual set is largely determined by the type of additional task ("what?" or "where?", i. e., stimulus recognition or spatial localization, respectively) introduced into the context of the experiment. It is suggested that the acquired set more readily shifts to a new one more adequate to modified conditions in case of alternation of the ventral and dorsal visual pathways involved in the information processing in the context of cognitive performance.
