Baddeley

Question 1

What was his aim

Answer 1

To investigate the influence of acoustic and semantic word similarity on learning and recall in STM and LTM.

Question 2

What was his sample

Answer 2

72 men and woman from applied psychology research unit

Question 3

What was his procedure

Answer 3

-Took place in a lab, all participants were given a hearing test before the study.
- Baddeley created 4 word lists containing 10 words on each where each P was given 3 seconds to look at it.
- P’s completed 6 tasks including memory for digits and asked to write them in order, they repeated this 4 times
- After the 4th trial they are given a distractor task for 15 minutes, after this they did a surprise recall.

Question 4

What were his results

Answer 4

-Acoustically similar words were recalled worse than dissimilar words during the initial phase.
-Semantically similar words were harder to recall in the surprise recall

Question 5

what was his conclusion

Answer 5

• Long term memory is encoded acoustically
  -Short term memory is encoded semantically

Question 6

Strengths AO3

Answer 6

G- 72 men+ woman; not androcentric or gynocentric, larger sample- can be generalised
OTOH- all from applied psychology unit; shared characteristics. Ethnocentric
R- standardised procedure; hearing test, word list had 10 words, can be repeated- increases reliability
Lab study; high control over variables, can be repeated- increases reliability
A- helps to understand memory; teaching/ revision
V- confidentail
Informed consent

Question 7

Weaknesses

Answer 7

V- Lab experiment; lacks ecological validity
Lacks mundane realism; remembering words-lowers validity
OTOH; extraneous variable was removed by hearing test- cause and effect
Each person did the task 4 times- leads to boredom
