PSYA02: Lecture 5 – Developmental: Cognitive Development
Piaget Theory of Cognitive Development:
Piaget did not conduct formal experiments, but rather loosely structured interviews in
which he posed problem for children to solve, observed their actions carefully, and
questioned them about their solutions.
He was particularly interested in children’s error, which would provide insight into
children’s thought processes.
He assumed that a child is an active seeker of knowledge and gains and
understanding of the world by operating on it.
Sometimes it is hard for children to solve problems, and this isn’t because of lack of
intelligence but rather they haven’t reached some milestone.
The errors were common among a particular age group.
Schemas:
Organized units of knowledge about objects, events, and actions.
Cognitive abilities.
It involves two abilities.
Assimilations is the interpretation of new experience in terms of present
schemas.
Accommodations is the modifications of present schemes to fit with new
experience.
For example, a child may call all four-legged creatures “doggie”.
The child learns he needs to accommodate (i.e., change) his schemas as only
one type of four-legged creature “dog”.
It is through accommodation that the number and complexity of a child’s
schemas increase and learning occurs.
Jean Piaget:
The notion of maturation and the stage like (think prerequisites) nature of cognitive
maturation.
The importance of operations, schemata’s, and the process of assimilation versus
accommodation.
Each child must go through each stage in order for them to develop.
The stages are:
Sensorimotor
Preoperational
Concrete operational
Formal operational
Piaget’s Stages of Development:
The sensorimotor period: Cognitive at this stage is closely tied to external stimulation,
and understanding characteristics of objects. Classic example is, object permanence.
Object permanence is the idea that people exist even if they aren’t there at the
time you are. Object permanence is the permanent existence of an object or
someone.
