Definition

The sensorimotor stage is Piaget’s first developmental stage, in which intelligence is organized through coordinated perception and bodily action before developed symbolic thought. RB2 illustrates grasping, sucking, kicking and searching, with emerging object permanence and causal understanding. The proposal retains Piaget’s stage framework and its local age range as historical description rather than a universal diagnostic timetable for every child.

Explanation

RB2 gives the stage as approximately the first two years within Piaget’s theory. Its central explanatory claim is that knowing grows through doing, not that an infant lacks every capacity for representation until an exact birthday. The native references anchor this presentation without establishing a new developmental assessment in the current review.

Object search, repeated manipulation and coordination give rise to schemas about objects, space and causes. The account contrasts action-based beginnings with later symbolic elaboration while preserving continuity between them. It does not reduce every learning event to one isolated reflex or make successful search the sole measure of infant intelligence.

AB’s embodied image-schema discussion and RB3’s account of acquired primary metaphors offer related later comparisons. They are not interchangeable with Piaget’s action schemas or independent proof of his complete stage sequence. The proposal preserves this attributed developmental sense without certifying universal timing, clinical normality or one identical mechanism across the books.

Scope and attribution
