Chapter 8: Information Processing

Children as Active Learners

  • Children are inherently active, inquisitive, and sense-making beings.
  • Their cognitive activities involve how they encode, store, and retrieve information.

Cognitive Development

  • Cognitive development is characterized by gradual increases in processing speed and capacity.
  • Changes are attributed to:
    • Neurological development.
    • Life experiences that enhance learning and memory.

Types of Attention

  • Sustained Attention: The ability to focus on a task for a continued period.
  • Divided Attention: Managing multiple tasks simultaneously (also known as joint or shared attention).
  • Selective Attention: Focusing on specific stimuli while ignoring others.
  • Executive Attention: Involves higher-level cognitive processing such as planning and decision making.

Attention in Infants

  • Requires a quiet, awake, and alert state to engage.
  • Strongly influenced by novelty in the environment.
  • Sustained attention spans are limited (only a few seconds) but improve as infants grow, particularly by the second year.
  • The gradual emergence of joint attention around 7 months significantly aids in language development and self-regulation.

Attention in Preschoolers and School-aged Children

  • Sustained Attention: Improvements occur as children mature, allowing longer focus durations.
  • Divided Attention: Children start managing more than one activity but may still struggle with efficiency.
  • Selective Attention: Defining tasks like the Dimensional Card Sort, where children categorize based on color or shape.
  • Executive Attention: Assessed through strategies that require planning and mental flexibility, as illustrated in various studies (e.g., Miniature Zoo task).

Memory in Infants

  • Recognition Memory: Ability to recognize previously encountered stimuli.
  • Recall Memory: Begins around 6 months; infants can recall information, becoming less context-dependent by 9 months.

Memory in Preschoolers and School-aged Children

  • Recognition Memory: Continues to develop and enhance.
  • Recall Memory: Improves with age, primarily due to:
    • Neurological developments that support memory functions.
    • An expanding knowledge base that aids memory recall.
    • The introduction and use of memory strategies.

Memory Strategies

  • Organization: Grouping information to aid recall.
  • Rehearsal: Repeating information to enhance retention.
  • Elaboration: Connecting new information to existing knowledge to improve memory.

Progression of Strategy Use

  • Production Deficiency: Child does not produce the strategies that help memory.
  • Control Deficiency: Child produces the strategy but does not apply it effectively.
  • Utilization Deficiency: Child applies strategies, but it does not lead to improved memory.
  • Effective Use: Child effectively utilizes strategies for optimal memory performance.

Theory of Mind and Metacognition

  • Theory of Mind: Awareness of one’s own and others’ mental processes and the ability to understand that these processes can be both accurate and inaccurate.
  • By age 5 or 6, critical understandings emerge:
    • Familiar items are easier to remember.
    • Short lists are easier to memorize compared to longer ones.
    • Gist-based remembering is favored.
    • Recognition memory is generally easier than recall memory.
    • There is an increased likelihood of forgetting over time.
    • Multiple interpretations of information are understood.
    • Children begin to select memory strategies based on their awareness of these principles.
