Object properties have been systematically associated with the Piagetian approach of cognitive development and in particular the sensorimotor period. Until the 1970’s, Piaget’s influential stance that knowledge of object properties is only learned from around nine months old had not been questioned. However, due to more contemporary studies there have been claims that not only do younger infants exhibit behaviours suggesting that Piaget’s assumptions may underestimate cognitive abilities but some studies have controversially suggested that newborns have shown to have a certain amount of innate knowledge. This has lead to claims that there are some innate or core cognitive abilities for dealing with object properties, in contrast to Piaget’s view that ‘humans do not start out as cognitive beings’ (Berk, 2009). It is important to state the significance of grasping the notion of object properties because according to Piaget this represents the start of symbolic thought or mental representation – an expression of intellectual behaviour (Davies & Houghton, 1991). However, this claim is a subject of dispute for investigators, who disagree on the degree of this inbuilt knowledge. This essay shall be using relevant research to critically evaluate the claim that infants have an innate knowledge of object properties, concentrating on the notion of object permanence.
Piaget theorised that knowledge of object permanence does not begin until the coordination of secondary circular reaction substage of sensorimotor period. He provided evidence for his assumptions, such as obscuring an object from an infant using a hand and seeing whether the child would reach for the object. Piaget concluded that the lack of searching by the infant implied a lack of object permanence, but Bower (1971) criticised Piaget’s use of search tasks because infants could
