Piaget's 4 Stages of Cognitive Development

Definition
  1. Sensory Motor Period (0-24 months)
  2. Preoperational Period (2-7 years)
  3. Concrete Operations Period (7-11 years)
  4. Formal Operations Period (11-15 years)
Term
6 Developmental Stages & Approximate Age
Definition
  1. Reflexive Stage (0-2 mo)
  2. Primary Circular Reactions (2-4 mo)
  3. Secondary Circular Reactions (4-8 mo)
  4. Coordination of Secondary Reactions (8-12 mo)
  5. Tertiary Circular Reactions (12-18 mo)
  6. Invention of New Means Through Mental Combination (18-24 mo)
Term
2 Developmental Stages & Approximate Age
Definition
  1. Preoperational Phase (2-4 years)
  2. Intuative Phase (4-7 years)
Term
Period of Concrete Operations
Definition

1 phase of development spanning ages 7-11

Term
Period of Formal Operations
Definition

1 phase of development spanning ages 11-15

Term
Reflexive Stage
Definition
  • Sensory Motor Period
  • 0-2 mos.
  • Development of simple reflex activity i.e. grasping, sucking
Term
Primary Circular Reactions
Definition
  • Sensory Motor Period
  • 2-4 mos.
  • Reflexive behaviors occur in repetitive form i.e. opening and closing fingers repeatatively
  • Term
    Secondary Circular Reactions
    Definition
  • Sensory Motor Period
  • 4-8 mos.
  • Repetition of change actions to reproduce interesting consequences i.e. kicking their feet to move a mobile suspended over the crib
  • Term
    Coordination of Secondary Reactions
    Definition
  • Sensory Motor Period
  • 8-12 mos.
  • Responses become coordinated into more complex sequences.
  • Actions take on an "intentional" character i.e. infant reaches behind a screen to obtain a hidden object
  • Term
    Tertiary Circular Reactions
    Definition
  • Sensory Motor Period
  • 12-18 mos.
  • Discovery of new ways to produce the same consequence or obtain the same goal i.e. the infant may pull a pillow toward himself in an attempt to get a toy that is on top of it.
  • Term
    Invention of New Means Through Mental Combination
    Definition
  • Sensory Motor Period
  • 18-24  mos.
  • Evidence of an internal representational system. Symbolizing the problem-solving sequence before actually responding.
  • Deferred imitation (taking time to think first)
  • Term
    Preoperational Phase
    Definition
  • Preoperational Period
  • 2-4 years
  • Increased use of verbal representation but speech is egocentric/self-centered/insensitive
  • Beginnings of symbolic rather than simple motor play.
  • Transductive reasoning: able to think about something without it being present by use of language: i.e. saying doggie, doggie yet no dog is present and no one else mentioned a dog.
  • Term
    Intuative Phase
    Definition
    • Speech becomes more social, less egocentric, limited instinctive grasp of logical concepts, still focuses 1 aspect of an object whil ignoring others
    • Concepts formed are crude & irreversible, reality not firm
    • Perceptions dominate judgment
    • In moral-ethical area child not able to show principles underlying best nehavior
    • Rules of a game under-developed, only use's simple do's & don'ts imposed by authority.
    Term
    Period of Concrete Operations
    Definition
    • 7-11 years
    • Evidence of organized, logical thought, ability to perform multiple classification tasks i.e. order objects in logical sequence and understands the concept of conservation
    • Thinking becomes less transductive & egocentric
    • Capable of concrete problem solving
    • Some reversibility possible i.e. 3+4=7 & 7-4=3
    • Able to sort unlike objects into logical groups, incl categorical labels i.e. "animal" or "number"
