Ferrera VP (2003). 10 One criticism of Piaget's theory is that culture and education exert stronger influences on a child's development than Piaget maintained. "Can monkeys (Macaca mulatta) represent invisible displacement?". 21 However, many other types of animals have been shown to have the ability for object permanence. At this stage the child understands causality and is goal directed. The infant's actions become less reflexive and intentionality emerges. This stage is associated with the classic A-not-B error. Also, it is an interesting example of how dynamic typing works in C#. 10 The wall was specifically designed to make the short carrot disappear, as well as tested the infants for habituation patterns on the disappearance of the tall carrot behind the wall (impossible event).
8 Contradicting evidence edit In more recent years, the original Piagetian object permanence account has been challenged by a series of infant studies suggesting that much younger infants do have a clear sense that objects exist even when out of sight. Piaget studied object permanence by observing infants' reactions when a favorite object or toy was presented and then was covered with a blanket or removed from sight. "Utility of the Uzgiris and Hunt seales of sensorimotor development with severely and profoundly retarded children".
If an object is completely hidden however the baby makes no attempt to retrieve. Recent studies edit One of the areas of focus on object permanence has been how physical disabilities ( blindness, cerebral palsy and deafness ) and intellectual disabilities ( Down syndrome, etc.) affect the development of object permanence. Bower showed object permanence in 3-month-olds. Novel behaviors are not yet imitated. 22 Similarly, cats are able to understand object permanence but not to the same extent that dogs can.
