state dependant forgetting

    Cards (2)

    • Explain the procedure of Carter and Cassaday (1998)
      > They gave anti-histamine drugs (for hay-fever) to their ppts
      > The anti-histamine drugs had a mild drowsy effect
      > This created an internal physiological state different from the 'normal' state of being awake and alert.
      > The ppts had to learn lists of words and then recall the information, again creating four conditions:
      1) Learn on drug - recall when on drug
      2) Learn on drug - recall when not on drug
      3) Learn not on drug - recall not on drug
      4) Learn not on drug - recall on drug
    • Explain the findings of Carter and Cassaday (1998)
      > In the conditions where there was a mismatch between internal state at learning and recall, performance on the memory test was significantly worse.
      > So when the cues are absent (for example, you are drowsy when recalling the information but had been alert when encoding it) then there is more forgetting.
