View mindmap
  • Forgetting
    • The experience of not being able to recall information such as an event, fact or a person's name
    • There are many theories of forgetting although a distinction can be made between availability and accessibility theories
    • Availability theories; memories are forgotten because they have been permanently lost from the brain
      • Trace decay theory argues that memories are forgotten because the physical trace left in the brain of a memory disappears over time
      • Mainly used to explain forgetting in short term memory
    • Accessibility theories; memories still exist but are difficult to retrieve
      • Cue-dependency theory argues that forgetting occurs when we have the information we are seeking but our memory lacks the cues to access it
      • Mainly used to explain forgetting in the long term memory
