Aim: To investigate the encoding of memory and the influence of acoustic and semantic words on memory.
- 4 lists of 10 words each (acoustically similar and dissimilar, semantically similar and dissimilar)
- Each list spoken - one word every 3 seconds
- They then carried out a distraction task - recalling 8 numbers.
- After repeating this four times, he asked participants to recall the words in order.
- Participants were allowed to see a jumbled list of words but not in order.
- Repeated x4
- After 15 minutes, he suprise tested them again - testing long term memory.
1st test - acoustic words couldn't be remembered as well as semantic words = STM is acoustic
2nd test - semantic words couldn't be remembered as well as acoustic = LTM is semantic
- Psychology students = demand characteristics
- Highly controlled - same questions, same distractions, repeated several times, lab experiment
- Not very applicable to real life - not everyday test (ecological validitity = low)
- May have been bored and not tried after 2nd test = order effects
- All ethical guidelines were met
