Language Development
Children learn their native languages
much before learning to add 2+2.
We learn, on average (after age 1), 3,500
words a year, amassing 60,000
words by the time we graduate from high
school.

Cognitive Development
Piaget believed that the driving force behind intellectual development is our biological development amidst experiences with the environment. Our cognitive development is shaped by the errors we make.

Schemas
Schemas are mental molds into which we pour our experiences.
8
Assimilation and Accommodation
Assimilation involves interpreting new experiences based on our current understanding (schema).• We view the world through
categories we have already developed
The process of adjusting a schema and modifying it is called accommodation.• We change & develop new
schemas in response to the world
Jean Piaget with a subject

Effect of Schemas on Thinking & Language
• Overextension– Applying a newly learned word
to objects that are not included in that word
– Occurs when we take a schema and apply it to understand things that really belong in a schema we have not yet developed
– EXAMPLES:• Dad has a beard. Therefore all
men with beards are called “dad”
• Our dog’s name is “harold,” so child calls all dogs “harold”
• Underextension– Failure to more generally apply a
newly learned word more generally to objects it really does apply to
– Occurs when our concept of a schema is more narrow than it should be.
– EXAMPLES:• Child learns that a red block is called
a “block”, but does not understand that a blue block is also a “block”
• Child learns that a Labrador retriever is a “dog,” but does not identify a Pit Bull as a “dog”
– Resolved through “accommodation” of the schema

PsychSym5 Module
1. Complete “Cognitive Development” module– KNOW PIAGET!!!!!
2. As you work, complete the “How Knowing Changes” graphic organizer/practice sheet
3. Done early? Develop questions for interview project.

Sensorimotor Stage: Criticisms
Piaget believed children in the sensorimotor stage could not think —they do not have any abstract concepts or ideas.
However, recent research shows that children in the sensorimotor stage can think and count.
1. Children understand the basic laws of physics. They are amazed at how a ball can stop in midair or disappear.
17
Sensorimotor Stage: Criticisms
2. Children can also count. Wynn (1992, 2000) showed that children stared longer at the wrong number of objects than the right ones.
18
Preoperational Stage: Criticism
DeLoache (1987) showed that children as young as 3 years of age are able to use mental operations. When shown a model of a dog’s hiding place behind the couch, a 2½-year-old could not locate the stuffed dog in an actual room, but the 3-year-old did.
19
Egocentrism
Piaget concluded that preschool children are egocentric. They cannot perceive things from another’s point of view.
When asked to show her picture to mommy, 2-year-old Gabriella holds the picture facing her own eyes, believing that her mother can see it through her eyes.
20
Theory of Mind
Preschoolers, although still egocentric, develop the ability to understand another’s mental state when they begin forming a theory of mind.The problem on the right probes such ability in children.
21
Concrete Operational Stage
In concrete operational stage, given concrete materials, 6- to 7-year-olds grasp conservation problems and mentally pour liquids back and forth into glasses of different shapes conserving their quantities.
Children in this stage are also able to transform mathematical functions. So, if 4 + 8 = 12, then a transformation, 12 – 4 = 8, is also easily doable.
22
Formal Operational Stage
Around age 12, our reasoning ability expands from concrete thinking to abstract thinking. We can now use symbols and imagined realities to systematically reason. Piaget called this formal operational thinking.
23
Formal Operational Stage
Rudiments of such thinking begin earlier (age 7) than what Piaget suggested, since 7-year-olds can solve the problem below (Suppes, 1982).
If John is in school, Mary is in school. John is in school. What can you say about Mary?
24
Reflecting on Piaget’s Theory
Piaget’s stage theory has been influential globally, validating a number of ideas regarding growth and development in many cultures and societies. However, today’s researchers believe the following:
1. Development is a continuous process.2. Children express their mental abilities and
operations at an earlier age.3. Formal logic is a smaller part of cognition.
Vygotsky• Russian Psychologist who focused on
educational theory• Zone of Proximal Development– Learning happens best when learner is challenged
but not overwhelmed
Interview Project
1. Develop questions for interview project.– Make sure Mr. G-G has seen and approved them
2. Make a plan for who you will interview.
