Building Schemes
• Assimilation: Taking in new information and attaching it
to the information already held (the existing schema);
• Accommodation: Changing the schema as a result of
the new information, thus adapting the way we behave
or think about something.
• Equilibrations: Significant developmental changes or
major restructuring of a child’s way of thinking.

Object Permanence
• Understanding that objects continue to exist when out of
sight
– 6-8 months will look for partially hidden object
– 8-12 months will search for object that has been completely
hidden
– Complete by 12 months
• A-not-B search error: where an object might be found is
limited
• More recent research suggests object permanence
develops sooner
