Q

baddeley procedure

A

Lab experiment asking them to recall acoustically and semantically similar
word lists. Each contained 10 words which were either acoustically similar,
acoustically dissimilar, semantically similar or semantically dissimilar. This is an
independent measures design – each participant does one word list
* They were first given a hearing test
* Then each word was presented for three seconds
* The participants were then required to complete six tasks involving memory for digits
and then asked to write down the words in the correct order. This was repeated 4
times
* After the fourth trial, they were given a 15 minute distractor task involving copying
numbers
* Lastly, they did a surprise recall (the words were shown on a card and they had to put
them in the correct order)

Q

baddeley results

A

Acoustically similar words were recalled worse than dissimilar words during
the initial phase (trial 2 in particular was statistically significant at P<0.05),
semantically similar (approx. 60%) were significantly harder to recall in the surprise
recall than the semantically dissimilar (approx. 85%) (p < 0.005)
