Document Summary
Cognitive development is the study of changes in memory, thought, and reasoning processes that occur throughout the lifespan. Piaget was interested in explaining how different ways of thinking and reasoning develop. Knowledge accumulates and is modified by 2 processes, assimilation and accommodation. Assimilation is a conservative process, whereby people fit new information into the belief system they already possess. The altering of these categories is accommodation, a creative process whereby people modify their belief structures based on experience. Piaget"s o(cid:271)ser(cid:448)atio(cid:374)s re(cid:448)ealed that (cid:272)og(cid:374)iti(cid:448)e development passes through 4 distinct stages from birth through early adolescence: sensorimotor, preoperational, concrete operational, formal operational stage. Advancing to the next stage occurs when the child achieves the important developmental milestone of that stage. The sensorimotor stage: living in the material world: Piaget named the earliest period of cognitive development the sensorimotor stage, from birth to 2 years, during which infants thinking about and exploration of the world are based on immediate sensory and motor experiences.
