Study Notes
Piaget's Theory of Cognitive Development
- Babies assimilate information using innate schemes like looking, listening, and sucking, while accommodating these schemes through experiences.
- The sensorimotor stage consists of six substages, each critical for cognitive growth.
- Substage 1 (0-1 month): Infants respond to available stimuli.
- Substage 2 (1-4 months): Coordination of primary actions centered on the infant's body; marked by primary circular reactions.
- Substage 3 (4-8 months): Infants repeat actions to elicit external reactions, demonstrating early means-end understanding.
- Substage 4 (12-18 months): Exploration, showcasing tertiary circular reactions through variations of previous actions.
- Substage 5 (18-24 months): Development of mental symbols leads to problem-solving abilities and understanding of object permanence around 2 months.
Accuracy of Piaget’s Sensorimotor Stage
- Piaget underestimated infants' cognitive capabilities; studies indicate object permanence recognition at around 5 months.
- Developmental object permanence may be a process of elaboration rather than merely discovery.
- Newborns show the ability to imitate facial gestures much earlier than Piaget proposed.
- Deferred imitation can occur as early as 6 weeks, contradicting Piaget's timeline.
Learning Theories in Infancy
- Classical Conditioning: Reflexive responses connected to stimuli.
- Operant Conditioning: Learning behaviors based on their consequences.
- Modeling: Learning through observing reinforcement or punishment of behaviors.
- The understanding of how infants learn is enhanced by these theories.
Categorical Self and Memory
- Toddlers develop an understanding of identity through categories such as gender and traits like shyness.
- Infants' memories are context-specific, developing category recognition as they take in information.
- By around 2 years, infants understand smaller categories within larger ones.
Bayley Scales
- Measures cognitive, language, and motor development aspects in infants.
- Intelligence is defined as the ability to adapt information to the environment, remaining relatively stable but modifiable by various factors.
- Factors affecting intelligence include early educational interventions and socioeconomic conditions.
Language Development Perspectives
- Behaviorist Perspective: Language acquisition through reinforcement from caregivers (nurture).
- Nativist Perspective: Children are innately equipped with a language acquisition device (LAD) for grammatical structures (nature).
- Interactionist Perspective: Language development emerges through biological preparedness and neurocognitive processes (nature and nurture).
Language Development Milestones
- 1-2 months: Infants begin cooing.
- 6-7 months: Babbling with consonants and vowels starts.
- 9-10 months: First words are spoken; understanding of 20-30 words emerges.
- 12-13 months: Expressive language develops; meaningful word use begins.
- 12-18 months: Unique communication through holophrases combining words and gestures.
- 16-24 months: Naming explosion occurs, with rapid new word acquisition.
Environmental Influences on Cognitive and Language Development
- Adult interactions significantly support language development and bolster emerging capacities in infants.
