Questions and Answers

What is the effect of mental inactivity following learning on memory?

    Study Notes

    The Law of Repetition

    • Spaced repetition promotes better long-term learning
    • Repetition with short delays can sometimes help
    • Testing improves memory beyond re-studying

    Forgetting

    • Forgetting can occur due to encoding failure or retrieval failure
    • Encoding failure: Not learning the material properly
    • Retrieval failure: Initially learned the material but unable to retrieve it later
    • Proactive interference: Previous learning interferes with new learning
    • Underwood (1957): More previous trials lead to poorer performance
    • Keppel & Underwood (1962): Almost no forgetting in the first 20 seconds

    Release from Proactive Interference

    • Wickens, Born, and Allen (1963): Switching stimulus type leads to better performance
    • Changing modality, semantic category, or part of speech can improve performance
    • Short-term memory is also affected by interference

    Consolidation Theory

    • Consolidation theory: Learned memories are in a vulnerable state initially (perseveration period)
    • Memories survive the perseveration period and enter the consolidation phase
    • Consolidation ensures permanent storage of memories

    Predictions of Consolidation Theory

    • Mental inactivity after learning enhances consolidation
    • Interruption before consolidation prevents memory storage
    • Retrograde amnesia: Loss of past memories due to trauma

    Retrograde Amnesia

    • Hippocampal amnesics: Loss of recent memories
    • Electroconvulsive shock (ECS) and removal of the hippocampus: Induce retrograde amnesia
    • Longer delay between learning and trauma, better memory: Supports consolidation theory

    Retrieval-Induced Forgetting (RIF)

    • Anderson, Bjork, and Bjork (1994): RIF provides evidence for inhibition theory
    • Strong competitors during retrieval practice are suppressed and show larger RIF effects
    • Weak competitors show little RIF effects

    Inhibition Theory

    • RIF is cue-dependent
    • More associations to a cue make it harder to remember something

    Interference Dependence of Inhibition Theory

    • Strong Rp- exemplars show strongest RIF effects
    • Weak Rp- exemplars show almost no RIF effects

    Cue Independence of Inhibition Theory

    • Forgetting is cue-dependent
    • More associations to a cue make it harder to remember something
