Notes on Information Processing

Information Processing Approach

  • Overview
  • Focuses on how individuals process information about the world.
  • Involves:
    • Manipulation of information
    • Monitoring of information
    • Creating strategies for handling information
  • Effectiveness relates to attention, memory, and thinking.

Key Components of Information Processing

  • Attention
  • Resources focused on specific information.
  • Types of attention:
    • Sustained Attention: readiness to respond to changes.
    • Selective Attention: focusing on relevant information while ignoring others.
    • Divided Attention: multitasking across activities.

Stages of Memory Processing

  • Three Main Processes:
  • Encoding: Getting information into memory.
  • Storage: Retaining information over time.
  • Retrieval: Taking information out of storage.

Memory Concepts

  • Schema Theory:
  • Memories are constructed and reconstructed based on existing frameworks (schemas).
  • Schemas influence how we encode and retrieve information.
  • False Memories:
  • New information can alter existing memories, impacting reliability, especially in eyewitness accounts.

Memory Types

  • Explicit Memory
  • Conscious recollection of facts (semantic) and experiences (episodic).
  • Implicit Memory
  • Unconscious memory of skills and routines (procedural).
  • Aging:
  • Older adults tend to have better recall of older memories than recent ones.

Developmental Changes in Memory

  • Infancy:
  • Babies have limited memory capabilities (infantile amnesia).
  • Childhood:
  • Improvements in short-term and working memory.
  • Adulthood:
  • Memory declines with age, especially in episodic memory.

Thinking Processes

  • Definition:
  • Manipulating and transforming information in memory.
  • Critical Thinking:
  • Deeper understanding and evaluation of information.
  • Often under-taught in schools.
  • Scientific Thinking:
  • Identifying causal relationships, using strategies to solve problems.

Metacognition

  • Definition:
  • Knowledge of one's own cognitive processes.
  • Metamemory: awareness of one's memory processes.
  • Theory of mind develops with age, reflecting understanding of others' thoughts and emotions.

Summary of Key Developmental Stages

  • Ages 2-3: Difficulty in perceiving others' thoughts.
  • Age 5: Understanding of false beliefs develops.
  • Middle Childhood: Awareness of mind as an active constructor grows.
  • Adolescence to Adulthood: Metacognitive skills and monitoring of thinking improve.

Aging and Cognitive Skills

  • Older Adults:
  • Often overestimate memory problems.
  • Performance can vary based on health, expectations, and cognitive training.
  • Caution with memory decline linked to physiological changes.

Strategies for Improvement in Cognitive Skills

  • Use Rehearsal, Organizing, and Elaboration techniques to enhance memory.
  • Practice critical thinking skills through discussions and deeper analyses.
  • Foster environments supporting learning, negotiation, and sharing knowledge.
