Phenomenal and rational perception by preschoolers of relations between objects

Two types of perception by children of spatial, qualitative, and quantitative relations between objects have been studied: phenomenal (direct) and rational (mediated). It is possible to show experimentally that under particular conditions both types of perception coexist in the behavior of children - though at different levels: rational perception reveals itself at the level of verbal reasoning, while phenomenal perception - at the level of practical behavior. Conditions are considered when phenomenal skills are suppressed by rational ones, and vice versa.
