Cognitive Development Study Essay -- Piaget’s Theory of Development

IntroductionThe purpose of this study is to analyse, in a functional way, the theories and concepts of cognitive development, crossways different age-related stages. Using Piagets theory of development, the cognitive ability of two subjects, aged 4 and 18 years, ar examined against the milestones of the individual preoperational and formal operational development stages. Cognitive ability is determined by focusing on the subjects capability and rationale to free radical 20 different objects. Based on the research outcomes, comparisons will be made to Piagets theory and the expected learning ability at their age-related development stage.Jean Piaget was considered a pioneer in cognitive research. Piaget develop his theory of cognitive development based on the sequence of changes that top to the cognition of a someone as they mature. Piaget believed that older children not scarce know quantitatively more than younger ones, but actually look at in qualitatively different ways. Children and adults are thought to possess an intrinsic ability to experiences organise their knowledge and into schemes (Lambert, 2007). Jean Piaget defined schemes as twain internalised behavioural patterns and mental understanding (Piaget, 1963, as cited in Berk, 2009). People are thought to actively seek knowledge and information from the surrounding purlieu and absorb or process this information using schemes. New knowledge is built on existing knowledge and as a mortal becomes older these schemes become increasingly more complex. This knowledge adds to a persons intelligence providing them with an adaptation to succeed or survive in the world (Piaget, 1963, as cited in Berk, 2009). Through this reasoning, Piaget determined that learning occurred across ... ...nstra, G., Koelen, M., Kok, F., and Graaf, C.
