Memory A level

Memory A level

1. Coding, capacity and duration

   • Coding
     • Once information gets into the memory system it is stored in different forms depending on memory store.
     • Alan Baddeley (1966)
       • Gave different lists of words to four groups of participants to remember.
       • Group 1 (acoustically similar) words sounding similar
       • Group 2 (acoustically dissimilar) words sounding different
       • Group 3 (semantically similar) words with similar meanings
       • Group 4 (semantically dissimilar) words that all have different meanings
       • Participants were shown the original words and had to recall them in the original order
       • When they had to do this recall task immedicately they tended to do worse with acoustically similar words (STM recall.)
       • When asked to recall the word list after a time interval of 20 mins (LTM recall) they did worse with semantically similar words
       • The study suggests info is coded semantically in LTM.
