Resource summary

explanations for forgetting: interference
  1. interference theory
    1. basics
      1. when 2 pieces of info conflict with each other
        1. proposed by an explanation of forgetting things in the LTM
          1. forgetting is because we cannot access it not because it isn't there
      2. types of interference
        1. proactive interference
          1. older memories interfere with newer ones
            1. pro = forward - old to new
          2. retroactive interference
            1. newer memories interferes with older ones
              1. retro = backwards - new to old
          3. effects of similarity
            1. McGeoch and McDonald - retroactive interference
              1. procedure
                1. all had to learn one list until 100% accurate
                  1. learn another list
                    1. group 1 = synonyms - same meanings
                      1. group 2 = antonyms - opposite meanings
                        1. group 3 = unrelated words
                          1. group 4 = nonsense words
                            1. group 5 = three digit numbers
                              1. group 6 = no new words
                2. findings
                  1. most similar words = greater interference
            2. evaluation
              1. evidence form lab studies
                1. 1000s of experiments like this have been done and all have the same results
                  1. increases validity and can be generalised
                2. artificial materials
                  1. the list used to remember has all been words or letters of some sort
                    1. we wouldn't have to do this in everyday life
                      1. not a way of explaining forgetting in everyday life
                  2. real life studies
                    1. Baddeley and Hitch
                      1. rugby players to say who they had played that season
                        1. those who had missed more games got more of them right
                          1. shows that it's not the period of time since they played it but how many games they have played after it
                  3. evaluation +
                    1. time between learning
                      1. lab experiments designed so that interference is at its max
                        1. but not too long so it is just forgetting
                          1. memory tests done within on hour
                      2. interference effects may be overcome using cues
                        1. Tulving
                          1. five lists of 24 words in six different categories
                            1. recall of the first list was 70% then decreased due to interference with the other lists
                              1. when given cues about the categories it increased again to 70%
