Piaget's Stages of Intellectual Development
The Sensori-motor stage (0-2 years)
Characteristics of this stage:
`knowledge' is simple motor reflexes, e.g. grasping (i.e. sensory and motor)
No object concept ­ i.e. no awareness of objects outside immediate present
General symbolic function develops by the end of this stage, i.e. CAT means...
Object permanence develops. This is the understanding that objects exist even when they
are out of sight
Piaget (1963) concluded that object permanence develops around 8 months
However...
Another explanation is that they may lack the necessary motor skills to search
Other studies have shown that 3 month old children have developed object permanence, e.g
Bower and Wishart ­ toy mobile
Refer to nativist findings
Piaget said that children, through assimilation, apply current schemas to a new situation. Lee did this
when he assimilated his schema of pushing his toy dog to pushing his toy car. Piaget also said that
children created new schemas for situations that they couldn't assimilate, through the use of
accommodation. Lee creates a new schema for pulling the fire engine because pushing the string
didn't work.
