    Study Notes

    Sensorimotor Stage Substages

    • Six substages: reflexes, primary circular reactions, secondary circular reactions, coordination of secondary schemas, tertiary circular reactions, and mental representation.
    • Reflexes occur from birth to 1 month, involving adaptations of instinctual responses.

    Mental Representation

    • Involves the ability to think about an object and create a mental image, allowing infants to use mental pictures.

    Piaget's Theory of Sensorimotor Development

    • Spans from birth to 2 years, where infants learn through senses and motor activities.
    • Development progresses from reflexes to intentional actions and symbolic representation.

    Primary Circular Reactions

    • Occur from 1 to 4 months; actions are repeated when they lead to pleasurable outcomes centered on the infant's body.

    Secondary Circular Reactions

    • From 4 to 8 months, infants repeat motor actions that produce interesting outcomes focused on the environment.

    Object Permanence

    • Understanding that objects continue to exist even when they cannot be seen, typically developed around 8 to 12 months.

    Tertiary Circular Reactions

    • Occur from 12 to 18 months; involve experimentation through trial and error to discover different ways to achieve the same goal.

    Mental Representation Substage

    • From 18 to 24 months; involves more complex thinking and problem-solving through internal exploration and deferred imitation.

    Violation of Expectation Method

    • Research design showing infants unexpected events to gauge their understanding of physical laws, indicated by longer attention on surprising outcomes.

    A-not-B Error

    • A common error where infants search for an object in the original hiding place even after witnessing its relocation, suggesting limited understanding of object permanence.

    Core Knowledge Perspective

    • Proposes that infants are born with innate knowledge systems that facilitate rapid learning and adaptation.

    Information Processing System

    • Comprises sensory memory, working memory, and long-term memory, detailing how information is encoded and retrieved.

    Attention and Memory Development

    • Attention increases throughout infancy and is linked to memory performance; memory enhances with age and context familiarity.

    Categorization

    • Infants categorize objects based on perceived similarities, with skills evolving from basic recognition to more complex categorization based on function and behavior.

    Bayley Scales of Infant Development

    • Measures infant intelligence through five scales; serves as a screening tool rather than predicting future intelligence.

    Approaches to Measuring Intelligence

    • Includes standardized tests and an information processing approach examining specific processing skills.

    Language Development Milestones

    • Begins with prelinguistic communication (cooing and babbling), progresses to holophrases (1-word expressions) and telegraphic speech (2-word utterances).

    Theories of Language Development

    • Learning theory emphasizes operant conditioning; nativist theory highlights innate learning capacities through a language acquisition device; interactionist perspective combines nature and nurture.

    Expansion and Recast Techniques

    • Expansion involves enriching a child's original statement for correction; recast involves delivering a grammatically correct version of the child's statement.

    Critiques of Language Theories

    • Learning theory cannot fully explain grammatical errors made by children; nativist theory lacks a clear mechanism for acquisition; interactionist perspective acknowledges the importance of parental interaction and responsiveness in language development.
