Study Notes
Cognitive Development in Infancy and Toddlerhood
- This lecture describes cognitive development in infants and toddlers, drawing on Piaget's, Vygotsky's and information-processing perspectives. Research findings supporting these perspectives will also be discussed.
Major Periods of Human Development
- Infancy and Toddlerhood (0-2 years): Body, motor, and cognitive changes occur along with the development of perceptual, mental, and first intimate ties with others.
- Early Childhood (2-6 years): Preschool years, where motor skills are refined, and a sense of morality develops alongside the beginning of peer relationships.
- Middle Childhood (6-11 years): School years marked by expanding motor skills, language, and thought processes. Understanding, morality, friendships, and peer-group membership all emerge.
- Adolescence (11-18 years): Puberty brings physical changes, sexual maturity, and more abstract thinking. Personal values, personal goals, & independence from family become increasingly important.
- Early Adulthood (18-40 years): Leaving home, developing a career, and potentially starting a family represent major concerns for this age group.
- Middle Adulthood (40-65 years): Most adults are at the peak of their careers and often have leadership positions. They support their children, and help their parents adjust to aging.
- Late Adulthood (65+ years): Adjustments to life changes, including the death of loved ones, become a key focus along with reflecting on life's meaning.
Content of the Lecture
- Piaget's Cognitive Developmental Perspective
- Information Processing Model
- Social Context of Early Cognitive Development (Vygotsky)
- Individual Differences in Early Mental Development
- Language Development
Piaget's Motor Stage (First 2 Years)
- Infants and toddlers think using their senses.
- Cognitive change occurs through schemes.
- A scheme is a psychological structure that organizes experiences.
- Adaptation involves building schemes through direct interaction with the environment.
Assimilation and Accommodation
- Assimilation: Using current schemes to interpret the external world.
- Accommodation: Creating new schemes or adjusting existing ones to account for new information or experiences.
- Organization: An internal process of linking schemes together.
The Sensorimotor Stage
- Circular reaction: Repeating actions. (e.g., sucking, grasping)
- Gaining control: Sitting up, reaching.
- Intentional behavior: goal-directed actions
- Coordination of schemes for problem-solving
- Imitation
- Deferred imitation: Copying the behavior of absent others
- Make-believe play: Acting and using imagination
Research on Infant Cognitive Development
- Violation of expectation method: Habituation research, recovery time. (Surprising an infant with an impossible event to understand physical laws awareness).
Research indicates that infants have a variety of abilities
- Object Permanence: Understanding objects continue to exist when out of sight. (Present in 1 month old infants, Aguilar & Baillargeon 1999)
- Mental Representation: Sensory
- Deferred Imitation: Imitating others' past actions/behaviors. (in the context of laboratory research)
- Problem-solving: Present by 10-12 months.
Cognitive Perspectives
- Core Knowledge Perspective: Infants start with core knowledge, and cognitive changes are continuous rather than stage-like. Aspects of cognition develop unevenly.
- Information Processing Model: This model challenges Piaget's theory. It suggests that speed and accuracy of cognitive processing is central to cognitive development.
Information Processing (cont.)
- Sensory Register
- Short-term Memory
- Long-term Memory
- Focus on strategies
- Baddely view
- Working memory
- Central Executive
Atkinson & Shiffrin Model
- Sensory Memory
- Short Term Memory
- Long Term Memory
Attention, Memory, and Categorization
- Attention: Shift from attending to a single high-contrast feature, as shown between 1 and 2 months.
- Memory: Habituation research provides information, infants show recall at 3-4 months.
- Recognition: Noticing a similar stimulus to a previously seen one,
- Recall: Recalling something not present physically.
- Categorization: Grouping items,
Autobiographical Memories
- Remembering events with personal meaning, typically developing by the end of toddlerhood.
Vygotsky Sociocultural Perspective
- Children develop in social contexts.
- Attention, memory, problem-solving.
- Social interaction plays a role.
- Proximal Development- Child performs tasks with guidance of a skilled person (zone of proximal development).
- Culture affects mental strategies.
Individual Differences in Early Mental Development
- Measures intellectual development (IQ tests).
- Comparing a person's performance to a larger sample of the same age.
- Perceptual and motor responses, used to predict later development.
- Developmental Quotients (DQs) rather than IQs, are used for infant tests.
Home Environment
- Home Observation for Measurement of the Environment (HOME): Gathering information about child's life using observation, and interviews.
- Organized stimulation, encouragement, parental involvement, affection, etc. predict early mental development.
- Child care factors play a role in developing cognitive development.
Language Development
- Three perspectives:
- Behaviorist: Language learned through imitation & operant conditioning.
- Chomsky: Innate language acquisition device (LAD)
- Interactionist: Innate abilities & rich linguistic environment.
Specific Language Stages and Processes
- Cooing (2 months) and Babbling (4 months)
- First words (12 months)
- Mistakes in using words (Under-extension)
- Over-extension: applying a word to a wider range of things than it refers to.
- Development of language (18-24 months) with spurts in vocabulary growth.
- Two-word utterances (telegraphic speech).
- Language comprehension surpasses production, even in special needs children.
Individual Differences in Language
- Girls learning language faster
- Names learned first (referential style)
- Expressive style (pronouns and social expressions)
- Adults use child-directed speech (CDS).
- Predicting language & academic competence through child-adult interaction/conversations.
Home work
- Prepare for cooperative learning discussion.
- Focus on theory of mind development in preschoolers.
Learning Outcomes
- Cognitive development in preschoolers.
- Piaget and Vygotsky in different perspectives.
- Role of discovery in cognitive development (Piaget).
- Role of guidance in cognitive development (Vygotsky)
- Importance of cognitive processing in information processing model.
