Piaget's Cognitive Developmental Theory: Piaget’s stages of cognitive development:
Sensorimotor- Infant -6mos.
Preoperational- 2-6mos.
Concrete Operations- 6-11mos.
Formal Operations- 12-
Sensorimotor- birth to age 2- initial major stage of cognitive behavior/ invariant order of stages individual different innate
1. Simple Reflexes ( 0-1 month)
2. Habits and primary circular reactions (1-4 month)
• Activity that permits the construction of cognitive schemes through repetition chance motor event
• Primary repeating of interesting of enjoyable actions
3. Secondary circular reaction (4-8 months) e.g. shake rattle
4. Coordination of secondary circular reaction (8-12 months) goal directed behavior object permanence *Understanding object continue to exist*
5. Tertiary circular reactions (12-18 months) desirable consequences
6. Beginning of thought (18-24 months) *Ability to form Mental Pic*
1. Capacity for mental representation (symbolic thought)
• Ability to pretend
• Deferred imitation
• Strengthening of object permanence
Information Processing:
Encoding- Process of information is initially recorded in form usable to memory
Storage- Maintenance of material saved in memory Retrieval- Process which material in memory storage is located (awareness and use)
Infantile Amnesia- Lack of memory for experiences that occurred before 3 yrs.
Language: systemic, meaningful arrangement of symbolic and provides the basis for communication
Phoneme- to the basic sounds of language; produce words and sentences
Morpheme- smallest language unit that communicates meaning
Semantics- the rules that govern the meaning of words and sentences Linguistic comprehension- the understanding of speech Linguistic production- use of language to communicate
Babbling- speech-like meaningless sounds infants make about 2-3 months until 1 yr.
Holophrase- one word utterance that depend the particular context which are used to
