Conservation tasks used by Piaget, James Mc Garrigle and Margaret Essay

Conservation lines used by Piaget, throng Mc Garrigle and Margaret Donaldson - Essay ExampleThe results suggest that whether children hold or not does not depend on either of the two tasks used but rather on their mastery of identity.This study aims at exploring Piagets caper on conservation in children and critically evaluating it in the light of the more recent procedure expound by (McGarrigle and Donaldson, 1975). Conservation is defined as the realization that number of items, measure or length is not related to arrangement or look of the objects or items. An examle is when a child is presented with a glass total of water, testament they be able to deduct that if that same water is transferred to a broader but plumper cup, then will it conserve the quantity and be the same Piaget argues that during the early childhood stage (below 6 years), childrens ability to coif logical mental operations is inadequate. In his research, Piaget identified four stages in cognitive develop ment to wit Sensorimotor stage (Infancy), Pre-operational stage(2-7 years), Concrete operational stage (7-11 years) and Formal operational stage (Adolescence through adulthood). ... Children in pre operational stage fail the the test of conservation because their thinking process does not comprehend the trio principles of reversibility, compensation and identity. This has been interpreted to mean that before authoritative ages children are not able to perceive things in certain ways. The theories have found wide usage especially in developing school curricula, just other psychologists have disagreed with them. They have argued that conservation tasks do not necessarily reveal an essential terminal point in the childs appreciation of quantity. Below are some of the arguments as to why children may fail to conserveThat the subjects may be distracted by the procedure.They may think that the experimenter wants them to answer in a certain way especially if the question is repeated.T hat the child may forget if the experimenter interfered with the information stored in Short terminal figure Memory. Porpodas (1987).The children may not understand the relational terms.That the conservation task being artificial would normally string no sense to a child. Lenz (2003) argues that Piaget does not take into account matters of simplicity or complexity of the task and that if a task is simple enough the child may perform correctly but if complex, eve an older child may make pre-operational mistakes. Indeed, in an effort to illustrate that children younger than in Piagets common age can conserve, many researchers have modified Piagets original procedure. For instance McGarrigle and Donaldson (1975) assert that if the transformation is bought closely accidentally then the number of 5-6 year olds conserving will go up.This study is to
