Week 3 Flashcards
Piaget’s cognitive developmental theory
- Birth to age 2 years
- Understand and act on the world using sensorimotor or behavioural schemes
Sensorimotor substages
*look up image
Object permanence
Developmental progression
- Under 6 months: no object permanence
- Emerges Substage 4
- > 8 – 12 months: search but A-not-B errors
- > Child searches where last found an object, not where we moved it (8 month old baby failing A not B test)
Criticisms of Piaget
Underestimated infant abilities
- > But correct general trend
- > Development not so stage like
Correct that sensorimotor skill assists some aspects of cognitive development
-> E.g., crawling assists depth perception and retrieving hidden objects
But evidence of some conceptual understanding before motor skills
Core knowledge perspective
Innate knowledge systems predispose us to understand the world and new information But require experience to extend this innate knowledge Suggested domains: - Physical - Linguistic - Psychological - Numerical - Morality?
Information processing perspective
*look up image
Cognitive gains in infancy and toddlerhood
Attention
- improved efficiency, ability to shift focus
- less attraction to novelty, improved sustained attention
Memory
- longer retention intervals
- development of recall by second half of first year
Categorisation
- gradual shift from perceptual to conceptual categorisation in toddlerhood
Vygotsky’s sociocultural theory
Like Piaget, constructivist, but emphasised social mediation of cognitive construction
-> Child as “little apprentice” (cf. Piaget’s “little scientist”)
Knowledge constructed via:
- Collective dialogues
- Collaborative learning
- Guided participation, scaffolding
- Imitation
Language development - nativist approach
Chomsky (1957) Language Acquisition Device (LAD)
- universal grammar hard-wired
- maturational unfolding
- fine-tuned by experience
Evidence
- Universal aspects of early language
- Uniquely human
- Specialised area left hemisphere
- Sensitive period 6 – 12 years
- look up image - language acquisition
Critique of nativist approach
- Hard to identify universal grammar
- Slower and more error-prone language acquisition than innate ability would predict
- Learning is important in language
- Brain plasticity shows other areas of brain capable of supporting language
Social interactionist view
- Children cue caregivers to provide necessary language experiences
- Language acquired via social interaction
- > Debate over whether there are also innate or specialised language abilities
- Social competence and language experience affect language progress
Characteristics of infants directed speech (IDS)
- higher pitch
- simple vocabulary
- sound substitution
- short sentences
- fluctuating intonation
- exaggerated expressions & gestures
Infant directed speech
IDS not essential but interaction is
-> e.g., Kaluli people of Papua New Guinea do not use “baby talk”
IDS plays a role in gaining attention, maintains communication
-> Provides opportunities for learning
Babies who are talked to/with more show greater language development
Infant communication development
- 4 months: interest in turn-taking games, gaze in direction adults looking
- 6 months: babbling initially universal sounds
- 6 - 9 mths: developing understanding of single words
- 10-11 months: joint attention
- 12 months: universality of babbling lost
- 9 – 12 mths: understands simple instructions
- 12 months: pre-verbal gesturing
- 10-15 months: first words
Telegraphic speech
single word conveys whole idea or whole sentence
-> word + context, gesture, intonation
First words and two words utterances
18-24 months:
- over-extension
- under-extension
- telegraphic speech
- correct word order associated with improved compliance
Child temperament and language development
Child temperament
- > E.g. emotional reactivity diverts children from processing language.
- > Quantity and richness and caregiver conversations
- > Referential vs. expressive style-What is language for?
Eriksons psychosocial theory - trust V mistrust
TRUST vs MISTRUST (0 – 1 year)
Successfully resolved by experiencing sympathetic, loving care
-> Broader focus than Freud’s narrow focus on oral gratification via breast feeding
Trust –> Prime adaptive ego quality: hope
-> Minimal fear or apprehension about future
-> Confidence to explore wider world
Implications for cognitive and social development
Mistrust –> Core pathology: withdrawal
Eriksons psychosocial theory - autonomy V shame and doubt
Importance of parental handling of emerging desire for autonomy
-> Cf. Freud’s narrower focus on toilet training
Over-controlling and under-controlling by parents both problematic
Criticism and punishment for failed attempts at autonomy –> shame & doubt
