ENCODING IN LTM

ENCODING IN LTM

1. BADDLEY

   • A: Find out about the nature of encoding in LTM
   • P: Four groups of pp's were given different lists of 10 words (Acoustically similar/dissimilar & semantically similar/dissimilar)
     • Interval of 20mins
       • Asked to recall the words in serial order
   • F: Recall worse for semantically similar words than semantically dissimilar
     • Recall the same for acoustically similar & dissimilar
   • C: Baddley concluded that encoding in LTM is mainly semantic

   • We encode differently in LTM
     • E.G. We recognise sound of sirens & a phone ringing (Acoustic encoding). We also remember faces (Visual encoding)
       • Semantic encoding is not the only method
   • Well controlled lab experiment (pp & situational variables tightly controlled)
     • Even though it was conducted in an artificial environment - Baddley used familiar words in all conditions
       • High in internal & external validity
