Jean Piaget proposed four stages of cognitive development from birth to adulthood: sensorimotor (birth to 2 years), preoperational (2 to 7 years), concrete operational (7 to 11 years), and formal operational (11 years and up). His theory focused on how children's understanding of the world develops through interactions with objects and people. Some criticisms are that the stages are too broad and do not fully explain development throughout the lifespan. The sensorimotor stage involves learning through senses and movement, while the preoperational stage includes symbolic thought and imagination. During concrete operations, logic and understanding of concepts like sequencing and conservation emerge. Formal operations involve abstract reasoning and hypothesis testing.

1. PIAGET’S STAGES OF
COGNITIVE DEVELOPMENT

2. The Stages of Cognitive Development by a Swiss
Psychologist named Jean Piaget is concerned with the
changes that occurs in the human intelligence from
birth to adulthood. In this theory, he suggests that
there are four stages in the intellectual development:
a. Sensorimotor (0 to 2 years)
b. Preoperational (2 to 7 years)
c. Concrete Operational (7 to 11 years)
d. Formal operational (11 above years)

3. Criticisms of Jean Piaget's Theory of
Cognitive Development
1.Does not study the entire lifespan
2. Underestimated what a child can do
3. Includes stages that are too broad
4. No description of Adult development
5. Formal Operational Stage where thought can be achieved as
early as 11 years of age was the most criticize part of his model
6. Does not fully explain child development
7. Suggests that cognitive development stops throughout
adulthood
8. Used his own child to perform the study

4. Sensorimotor Stage
This is the area of development starting at birth to 2
years of age. During this phase, child explores and
gather knowledge with the help of their senses and
motor abilities to undergo cognitive growth. Little ones
in this period learns about the world by gazing,
touching, tasting, and banging things together. In this
stage, humans are egocentric, where they see the
world only in their point of view.

6. Preoperational Stage
During this stage (toddler through age 7), young
children are able to think about things
symbolically. Their language use becomes more
mature. They also develop memory and
imagination, which allows them to understand the
difference between past and future, and engage in
make-believe.

7. Timeline of the Preoperational
Stage
Two substages occur during the
preoperational period of development:
• SYMBOLIC FUNCTION ( ages 2 to 4)
• INTUITIVE THOUGHT (ages 4 to 7)

8. CONCRETE OPERATIONAL STAGE
•The concrete operational stage is the third
stage in Piaget’s stages of cognitive
development.
• From the ages of 7-12, children develop
increasingly advanced reasoning. Their thinking
becomes better organized, more logical and
systematic.

9. CHARACTERISTICS OF CONCRETE
OPERATIONAL STAGE
1.) SERIATION IN THE CONCRETE OPERATIONAL STAGE
• This term refers to the child’s ability to arrange objects in
sequence, such as from smallest to largest or hardest to softest.
2.) REVERSIBILITY IN THE CONCRETE OPERATIONAL STAGE
• One important development in this stage is an understanding of
reversibility or awareness that actions can be reversed. An
example of this is being able to reverse the order of relationships
between mental categories.

10. 3.) CONSERVATION IN THE CONCRETE OPERATIONAL STAGE
• Another key development at this stage is the understanding that
when something changes in shape or appearance it is still the same, a
concept known as conservation.
TIPS FOR ACTIVITIES IN THE CONCRETE OPERATIONAL STAGE
• Playing with building blocks
• Pouring liquids into different-sized containers to demonstrate
conservation
• Doing things for other people to help kids think about other
perspectives
• Reading books and talking about what a child thinks might happen
next

11. Formal Operational thinking
• The ability to create hypotheses
and conduct methodical tests on
them in order to find a solution to
a problem defines the formal
operational stage. In addition to
being able to reason abstractly,
someone in the formal stage may
comprehend the shape or
structure of a mathematical
problem.
