TRANSCRIPT
Sensorimotor Intelligence• Learned through the senses• Circular reaction
• Sensation – perception – cognition cycle around and around
Primary circular reaction• Stage 1 ( Reflexes)
• Birth – 1yr.• Responding to own body
• Grasping• Sucking• Stepping
• Stage 2 (Habits)• 1 – 4 Months• Adapting reflexes to new situations
• (Acquired adaptation)• E.g. Sucking from mom’s nipple to bottle to pacifier
• A sign baby is thinking
Secondary circular reaction• Responding to other people & objects• Stage 3 (Continuing interaction)
• 4 – 8 months• Making interesting sights last
• Stage 4 ( Starting interaction)• 8 mos. – 1yr.• Infant has goals• Initiates and anticipates
• Initiates• E.g. Patty-cake
• Anticipates• E.g. Running from an unwanted bath
• Object permanence
Tertiary circular reaction• Stage 5 (Acts independently - Experimenting)
• 1 yr. - 18 mos.• Active experimenting
• “Little scientist”
• Stage 6 (Thought before action)• 18 mos. – 2yrs.• Thinks about consequences• Deferred imitation
Affordance ( opportunities)• Opportunities to interact with
people and things• Visual Cliff
• Based on experience• 6 month will go over cliff• 10 Month will refuse
Memory• Implicit
• Hidden• Unconscious habits, emotions procedures• Early language, smells, places
• Explicit• Stored in the hippocampus• Usually verbal• Recalled on demand• Words, data, concepts
• Reminders help
Universal sequence• Reflexes, cooing, babbling, spoken words
• All babies, regardless of native language follow this sequence
• Listening & Responding• Babbling
• E.g. ma-ma-ma, da-da-da
• Holophrase• One word = phrase
• E.g. Cookie, Dada!
• Naming explosion• 1 yr. to 18 months• Nouns
• Ma-ma, da-da, na-na
• Elimination• Pee-pee, wee-wee, poo-poo
1. Learning theory• Based on B.F. Skinner
• Reinforcement• E.g. Parents talking to children
• Children learn what they hear
3. Innate• Norm Chomsky• Children have an inborn ability to learn language• E.g. Grammar• Hypothesized a Language Acquisition Device (LAD) in the
brain.• Enables universal inborn ability to learn language
• Language in general is experience-expectant• Words are expected by the developing brain
• Specific language is experience-dependent
