Critically evaluate the evidence that Piaget underestimated childrens abilities in the pre-operational stage - Essay exemplarThis stage of development lasts from age two to six.Critics have stated that Piaget underestimated childrens abilities in the pre-operational stage and this is establish mainly on the following grounds (a) the child in the pre-operational stage is uneffective to conserve the race between the different dimensions of an levelt (b) Piagets theory held that children in the preoperational stage may be unable to understand object permanence (c) Piaget has underestimated the ability of children to see the world from another persons tie-up and referred to this as egocentrism.One of Piagets major findings about the pre-operational stage was that children cannot conserve different dimensions of an event. For example, when a physical composition of clay is molded into two different shapes, the child is unable to understand that although the shape is different, the p iece is essentially the same.(Salkind, 2004, pp 249). However, in experiments conducted by Wynn (1992), on five month old infants, the findings appear to suggest that infants may even be able to calculate results for simple arithmetic operations on a small consider of items. Human beings may therefore possess innate arithmetical abilities. Similarly, Xu and Spelke (2000) have also shown that when extraneous variables argon controlled, infants argon able to discriminate between large sets of objects on the basis of numerosity. This suggests that Piagets findings may be lacking in some aspects.Piaget appears to have underestimated the timing of development of childrens abilities and one example of a cognitive defect attributed to the pre-operational stage is the inability to comprehend object permanence, i.e, that an object continues to exist even when it is travel out of sight.(Hetherington and Parke, 2003). In examining object permanence, Piaget concluded from his observations tha t young children appear to view objects as ephemeral entities which are constantly made and unmade
