Chapter 7 cognition

Chapter 7: Cognition

  • Cognition: the activity of knowing and the processes through which knowledge is acquired and problems are solved

  • Constructivism – people are active learners


Jean piaget 1896 1980

Jean Piaget (1896-1980)

  • Genetic Epistemology

    • How we come to know reality

  • Clinical Method

    • Question and answer technique

    • Used to discover how children think about problems


Clinical method example of a 6 year old

Clinical Method (example of a 6 year old)

  • Piaget: Why is it dark at night?

  • Van: Because we sleep better, and so that it shall be dark in the rooms.

  • Piaget: Where does the darkness come from?

  • Van: Because the sky becomes grey.

  • Piaget: What makes the sky become grey?

  • Van: The clouds become dark.

  • Piaget: How is that?

  • Van: G-d makes the clouds become dark.


Piaget

Piaget

  • Intelligence: How well we adapt

    • Scheme (s) or schema (schemata)/cognitive structures

  • Organization

    - Children systematically combine existing schemes into new and more complex ones.

    - E.g., infant who gazes, reaches, and grasps will organize these simple schemes into a complex structure called visually directed reading.


Chapter 7 cognition

  • Adaptation

    • Adjusting to the environment

    • Using assimilation and accommodation

  • Assimilation

    • Using existing schemes to interpret new experiences

    • E.g., Birds are things that fly

  • Accommodation

    • Modifying schemes to fit new experience

    • E.g., Butterflies are different than Birds even though they both fly

  • Equilibrium

    • A resolution of conflict to create a balance


Chapter 7 cognition

Cognitive DevelopmentPiaget’s Theory

  • Piaget’s Four Stages

  • Cognition unfolds in a sequence of four stages.

  • Each is age-related and distinctive.

  • Each stage is discontinuous from and more advanced than another.


Piaget1

Piaget

  • Sensorimotor Stage

    • Newborn uses reflexes to understand world

    • Eventually - mental representation

      • Object Permanence

      • A, not B, error – 8 to 12 month-olds search for an object in the place where they last found it (A) rather than in its new hiding place (B).

    • Symbolic Capacity (read in book)


Chapter 7 cognition

Sensorimotor stage


Symbolic function substage 2 4 years

Symbolic Function Substage(2-4 Years)

  • Symbolic thought: Mental representation of an object that is not present (drawing, pretend play, and language)

  • Egocentrism: The inability to distinguish between one’s own perspective and someone else’s perspective.

  • Animism: The belief that inanimate objects have “lifelike” qualities and are capable of action.


Chapter 7 cognition

Can this boy report what the clown doll sees?


Chapter 7 cognition

They Centrate: Focusing on one characteristic to the exclusion of others.

No Conservation: Some characteristic of an object stays the same even though the object might change in appearance.


Chapter 7 cognition

Piaget’s Conservation Task


Chapter 7 cognition

  • Intuitive rather than logical

  • Lack classification ability

  • Lack conservation due to static thinking, irreversible thought and centration

  • Asks a lot of questions

    • signals the emergence of the interest in reasoning

    • reflects intellectual curiosity


Chapter 7 cognition

How would you group these?


Chapter 7 cognition

Classification

v

v

This grouping is by shape and size and color. It is

multiple classification. The child has to think of three

dimensions at once. In what stage could the child do this?


Chapter 7 cognition

Preoperational stage


Chapter 7 cognition

Conservation of Length

Is one of these lines longer or are they they same?

What would the pre-operational child say?


Chapter 7 cognition

Conservation of Length

The preoperational child would say the one on

the top is longer. Pre-operational children

base their concepts on perception, not logic.


Chapter 7 cognition

Conservation of Length

Are all of these lines the same length? Is one longer?

What would the pre-operational child say?


Chapter 7 cognition

Conservation of Length

Preoperational children are tricked by perception.

The think the one “out front” is longer.


Chapter 7 cognition

Conservation of Area Which side has more green?


Chapter 7 cognition

Both have the same area of green. Preoperational children rely on perception and think the one on the right has more.


Chapter 7 cognition

Conservation of Number

Do these two rows have the same number of balls?

Do these two rows have the same number of balls?

Which has more?


Chapter 7 cognition

Conservation of Number

Pre-operational children think the row on the

bottom has more. Later they develop

one-to-one correspondence.

They understand there is one for this

one, one for that one, and one for that one, etc.


Concrete operations

Concrete Operations

  • Age 7-11

  • Can conserve

    • Decentration

    • Reversible thinking

    • Logical thinking (limited to reality)

  • Seriation and classification

  • Transitive thinking:

    • “ If J is taller than M, and M is taller than S, who is taller – J or S?”


Chapter 7 cognition

Figure 7.4


Short answer

Short Answer

When a child can focus on both width and length of two triangles in order to compare their areas, Piaget would say that the child is capable of _________________.


Formal operations

Formal Operations

  • Adolescence/puberty

  • Logical thinking about ideas

    • Hypothetical and abstract thinking

    • Hypothetical-deductive reasoning – from general ideas to their specific implications

  • Decontextual thinking

    • Ability to separate prior knowledge/beliefs from new evidence to the contrary


Formal operations 2

Formal Operations 2

  • Adolescent egocentrism

    • Differentiating own thoughts from others’

      • Imaginary audience

        • Also, learning to present themselves to a real audience

      • Personal fable

        • “No one has ever felt like this before!”

        • “I drive better when I’m drunk!”


Cognition in adulthood

Cognition in Adulthood

  • Formal operations requires

    • Normal intelligence

    • Higher education (scientific thinking)

  • Lower performance on formal operations

    • Use only in field of expertise

  • Postformal thought

    • Relativistic thinking: Labouvie-Vief

    • No absolute answer in many situations


  • Piaget2

    Piaget

    • Contributions

      • Stimulated much research

      • Correct about the sequence of cognitive development

    • Challenges

      • Underestimated young minds

      • Focused on performance not competence

      • Domain specific rather than stages

      • Social influences left out (too much the “isolated scientist.”


    Vygotsky

    Vygotsky

    • Emphasized the socio-cultural context

      • Culture affects how and what we think

    • Zone of Proximal Development (ZPD)

      • Accomplishment with guidance

      • Where lessons should be aimed

    • Guided participation (a form of scaffolding) learning

    • Private speech/ guides behavior (3 & 4 yr olds)


    Cognitive development vygotsky s theory

    Cognitive DevelopmentVygotsky’s Theory

    The Zone of Proximal Development (ZPD)

    student can work with the student can work

    assistance of an instructor ________________________ independently

    Language and Thought

    • Develop independently of each other

    • Have external or social origins

      Scaffolding

      Teacher adjusts the level of support as performance rises

    ZPD


    Chapter 7 cognition

    Applications of Vygotsky’s Theory

    • New Task = Mentor + Learner

    2.Time Passes = Gradual Release

    3. Learner Takes on the Responsibility for learning

    Scaffolding
