    Flashcards

    Expertise and Memory

    Experts remember more about information relevant to their area of expertise. This is because expertise leads to more efficient information acquisition and organization.

    Child Expertise

    Children demonstrate better memory when the information relates to their area of expertise (like toys, dinosaurs).

    Knowledge & Memory Tasks

    Children often underperform at memory tests because they lack knowledge (expertise) about the materials in the tests. Known materials lead to better performance.

    Encoding/Retrieval Effort

    Familiar material requires less mental effort to encode (store) and retrieve relevant information compared to unfamiliar information.

    Study Notes

    Cognitive Development Through Adolescence

    • Cognitive development is a complex process shaped by both biological and environmental factors.
    • Piagetian theory posits that development progresses through distinct stages, each characterized by qualitatively different cognitive abilities.
    • The sensorimotor stage (birth to 18 months) is characterized by infants interacting with the world through senses and motor actions. Object permanence develops during this stage.
    • The preoperational stage (2-7 years) involves symbolic thought, language acquisition, and egocentric thinking. Children at this stage may struggle with concepts like conservation.
    • The concrete operational stage (7-11 years) is marked by logical reasoning and the understanding of conservation, classification, and reversibility.
    • The formal operational stage (adolescence and beyond) is characterized by abstract, hypothetical thinking and the ability for systematic reasoning.

    Non-Piagetian Approaches

    • Non-Piagetian approaches focus on the continuous development of cognitive abilities.
    • Information-processing models compare the mind to a computer, highlighting processes like memory, attention, and processing speed.
    • These models emphasize that cognitive abilities develop gradually throughout childhood and adolescence.
    • Factors such as neurological maturation, attention, knowledge, and speed of processing affect cognitive development.
    • The knowledge base and knowledge structures are essential ingredients of cognitive development.

    Stages of Cognitive Development

    • Stage theories describe development as occurring in discrete stages, with each being qualitatively unique
    • Non-stage theories view development as a continuous process
    • Some approaches look at particular areas of development (e.g. memory)

    Some Post-Piagetian Answers to the Question "What Develops?"

    • Neurological maturation is a major contributor to cognitive development.
    • Working-memory capacity and processing speed increase with age.
    • Attention and perceptual encoding become more sophisticated over time, allowing more complex information processing.
    • An understanding of one’s own cognitive abilities (metacognition) emerges.
