1. The document summarizes Jean Piaget's theory of cognitive development, which proposes four stages of development: sensori-motor, pre-operational, concrete-operational, and formal operational. 2. The pre-operational stage is characterized by egocentrism, centration, irreversibility, and animism. In the concrete-operational stage, the child can think logically about concrete objects and exhibit decentering, reversibility, conservation, and seriation. 3. In the final formal operational stage, thinking becomes more logical and abstract, allowing for hypothetical reasoning, analogical reasoning, and deductive reasoning.

2. Basic Cognitive Concepts
 Schema
– It is an individual’s way to understand or
creating meaning about a thing or experience.
 Assimilation
- The process of fitting a new experience into an
existing or previously created cognitive structure or
schema.
Accommodation
– The process of creating new schema.
Equilibrium
- It is achieving proper balance between
assimilation and accommodation.

Cognitive Development
Stages of

4.  Stage 1. Sensori-motor Stage
– During this stage, children
begin to make sense of the world by
using their sensing impressions and
motor actions.
 Object Permanence
– The ability of the child to know that
an object still exists even when out
of sight.

5. Stage 2. Pre-operational Stage
– Intelligence of the child is
intuitive in nature.
 Symbolic Function
– The ability to present objects and
events.
 Egocentrism
– The tendency of the child to only
see his point of view and to assume that
everyone also has his the same point of
view.

6.  Centration
– The child to only focus on one aspect of
a thing or event and exclude other aspects.
 Irreversibility
– Inability to reverse their thinking.
 Animism
– The tendency of children to attribute
human like traits or characteristics to inanimate
objects.
 Transductive Reasoning
– The pre-operational child’s type of
reasoning that is neither inductive nor
deductive.

7. Stage 3. Concrete-operational Stage
– The ability of the child to
think logically but only in terms of
concrete objects.
 Decentering
– The ability of the child to perceive
the different features of objects and
situations.
 Reversibility
– The child can now follow that
certain operations can be done in reverse.

8.  Conservation
– The ability to know that the
certain properties of objects do not
change even if there is a change in
appearance.
 Seriation
– The ability to order or
arrange things in a series.

9. Stage 4. Formal Operation Stage
– Thinking becomes more
logical. They can now solve abstract
problems and can hypothesize.
 Hypothetical Reasoning
– The ability to come up with
different hypothesis about a problem
and to gather data in order to make a
final decision or judgement.

10.  Analogical Reasoning
– The ability to perceive the
relationship in one instance and then
use that relationship to narrow down
possible answers in another similar
situation or problem.
 Deductive Reasoning
– The ability to think logically
by applying a general rule to a
particular instance or situation.
