Retrieval failure

Cards (11)

  • Encoding specificity principle
    • tulving and thomason explained this effect in terms of encoding specificity principle
    • Recall is better if the retreival context is similar to the encoding context
    • Any cues present at the time of coding must be present at the time of retrieval (the closer it is to the original the more useful it will be)
  • Context dependent forgetting
    • Recall depends on external cues
    • Location, weather, sights + sounds
  • Abernethy
    • Arranged for a group of students to be tested
    • Group 1, same room same teacher
    • Group 2, same room diff teacher
    • Group 3, diff room same teacher
    • Group 4, diff room diff teacher
    • Those tested by their teacher in their classroom performed best - familiar objects acted as cues
  • State-dependent cue
    • Recall depends on internal cues
    • e.g mental state, feelings or an altered state (e.g being drunk)
  • Goodwin
    • asked male volunteers to remember a list of words when either drunk or sober
    • they were asked to recall after 24 hours - findings show that info learnt drunk is more available when in the same state
  • Tulving and Pearlstone
    • Participants instructed to remember 48 words in 12 sets of 4 words and were told they would not be asked to recall headings of categories
    • The control group were asked to recall as many as they could
    • The experimental group were given headings as cues
    • Control group recall was 40% and experimental group was 60%
  • Tulving and Psotka
    • Demonstrated that apparent inference effects are actually due to the absence of cues when they come to recall
    • Proved that info is there but cannot be retrieved and shows retrieval failure is a more important explanation of forgetting than inference.
  • Strengths
    • a lot of research supporting the theory - including lab, field and natural experiments - applicable to real life
    • Tulving and pearlstone - proved that you can improve memory through the use of mnemonics or category headings
  • Retrieval failure is a type of forgetting where information is lost because it cannot be accessed from long term memory.
  • Weaknesses
    • retrieval cues don’t always work - info you are learning is a lot more than just cues
    • word lists are often used in research - irl more complex info is learned
    • Cues explain everyday forgetting but not all
    • The danger of circularity
  • Danger of circularity
    Nairne - cues do not cause retrieval they are just associated
    Baddely - the encoding specificity principle is impossible to test because it is circular. If a stimulus leads to the retrieval of a memory it must have been encoded in the memory
