Essay: Cognitive Development Stages of Children
The children cognitive development stages were constructed and formulated basing on the logical errors children make in reasoning. In the processes of formulation, children at similar stage, made similar logical errors hence facilitated the grouping of this and thereafter categorization of developmental stages. These categorization of children who made similar logical errors in thinking, justified four cognitive development stages.
Sensory motor stage
This stage occurs during the infancy stage of a child when an infant is between 0 to 2 years of age. In this stage, there are six sub-stages involved refer to table 1(appended documentation). This stage encompasses intelligence, knowledge of the world, physical development and symbolic abilities development. Importantly, intelligence is illustrated through motor activities, while knowledge about the world is limited but still in the process of developing based on the physical experiences. Mobility (physical development) facilitates development of new intellectual abilities and child acquires object permanency that enhances the memory. Moreover, at the end of the stage as transition to the pre- operational stage the child develops language abilities (Slee, 2002, p. 193).
This cognitive development second stage, starts from two to seven years and is exhibited by toddler and early childhood, it has two sub stages which are preconception from 2 to 4 years dominated by geocentricism and animism. While the second sub stage is intuitive that reigns from 4 to 7 years when a child starts to employ thinking, solve issues and problems. Generally, intelligence of the child is depicted by symbols, advanced use language. Memory develops although thinking is done basing on non-logical manner.
