|
Term
| 2 Developmental Stages & Approximate Age |
|
Definition
- Preoperational Phase (2-4 years)
- 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
|
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
|
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
|
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"
