- Baddeley 1966B study
- Aim
- To see the influence of acoustic and semantic word similarity on learning and recall in STM and LTM.
- Procedure
- Lab Experiment
- Can establish cause and effect
- Operationalised IV and DV
- Sequential recall of acoustically similar and semantically similar words
- Ppts
- Male and Female - No gender differences in memory
- Results can be generalised to all genders
- From Cambridge Applied Psych Unit - Biased Sample, already had an understanding of psychology
- Male and Female - No gender differences in memory
- Independent design
- Split into 4 groups
- 4 word lists
- List C- Semantically similar
- List B- Acoustically different
- Control groups of A and C
- List D- Semantically different
- Control groups of A and C
- List A- Acoustically similar
- 4 word lists
- Split into 4 groups
- Words projected onto wall for three seconds
- Had one minute to recall as many as possible in the correct sequence
- STM test
- 4 learning trials (rehearsal)
- Maintenance then elaborative
- Given a 15 minute interference task
- Given a sudden test
- LTM test
- Given a sudden test
- Had one minute to recall as many as possible in the correct sequence
- Lab Experiment
- Results
- Ppts found it difficult to recall acoustically similar words when in STM
- Difficulty recalling semantically similar in LTM
- Conclusion
- LTM = Semantic encoding
- STM = Acoustic encoding
- Evaluation
- Strengths
- Lab Experiment
- Could establish cause and effect
- Highly controlled
- Very reliable
- Focused on one part of memory only
- Simplifying brain processes
- Made sure he was testing only what he wanted to test
- Simplifying brain processes
- Lab Experiment
- Limitations
- Artificial
- Don't learn word lists everyday
- Overuse of rehearsal
- Lacks mundane realism
- Don't learn word lists everyday
- Lacks mundane realism
- Lacks mundane realism
- Lowers internal validity
- Learning trials
- Rehearsing more than would usually be done in everyday life
- Overuse of rehearsal
- Overuse of rehearsal
- Rehearsing more than would usually be done in everyday life
- Artificial
- Strengths
- Aim
