- Encoding
- STM
- info enters in original form into the sensory store
- three main types of encoding used in memory
- acoustic coding (sound)
- visual (appearance)
- semantic (meaning)
- three main types of encoding used in memory
- encoding in STM is mainly acoustic
- Conrad 1964
- laboratory experiment
- participants shown random sequence of six constants
- one group given acoustically simiar letters
- B,G,C,T,D,V
- other group given letters that were acoustically dissimilar
- F, J, X, M, S R
- immediately after participants were asked to recall as many letters as possible in the correct order
- participants found it difficult to recall words that were similar
- we convert visual info into acoustic info in STM
- this makes it difficult to distinguish between words that are accoustcally similar
- we convert visual info into acoustic info in STM
- evaluation
- lacks mundane realism, can't be related to real life
- participants included students, doesn't represent the whole population
- info enters in original form into the sensory store
- LTM and STM
- encoding in LTM is semantic
- laboratory experiment
- Baddeley 1966
- one group
- first list acoustic similar words
- mad, map, mat, cat, cap, cad
- acoustically dissimilar
- pen, cow, pit, sup, day
- asked to recall immediately
- first list acoustic similar words
- second group
- semantically dissimilar
- foul, thin, late, safe, strong
- semantically similar
- tall, high, broad, wide , big
- given ten words and participants were prevented from rehearsal with a distracter task
- tested after 20 mins
- semantically dissimilar
- in STM participants remembered acoustically similar worse, in LTM semantic words were remembered worse
- lacks mundane realism
- both independent measures designs
- STM
- second group
- semantically dissimilar
- foul, thin, late, safe, strong
- semantically similar
- tall, high, broad, wide , big
- given ten words and participants were prevented from rehearsal with a distracter task
- tested after 20 mins
- semantically dissimilar
