=__Piagets Theories of Cognitive Development __=
 * =Between 1923 and 1946 Piaget observed his own children and from these observations he argues that children from birth to 14 yrs go through 4 stages of development: =


 * 1) =====Sensory motor period =====
 * 2) =====Pre-operational period =====
 * 3) =====Period of concrete operations =====
 * 4) =====Period of formal operations. (Cohen, 2003 ) =====


 * ﻿Piaget believed that acquiring knowledge developed from a childs movement as this allows for sensory motor co=ordination and subsequently //schemas// are built up. A schema is a mental design or representation and Piaget explanined the development of these concepts as: Assimilation & Accomadation.


 * Assimilation: We constantly take in information through our senses from the time we are born and our brains cannot cope with such an overload. It therefore filters out some of the information so we are not completely bombarded.


 * Accomadation: Is the perceptual process of filtering out this information. For Piaget 'accomadaton occurs when the enviroemnt acts on the organism' and as a result 'the organism has to re-adjust and re-organise itself'. (Cohen, 2003. p.37)
