    • Generalisability:                   P- One weakness of Baddeley's study is that it lacks generalisability                      E- There were 72 participants (males and females) with a background in Psychology.  E- It is a small sample and the findings are not representative of the whole population. Results could have been due to chance
    • Reliability          P- A strength of the study is it can be tested for reliability.         E- Because it is a lab experiment with control over extraneous variables and had standardised procedure. For example he used the same word list for each participant in the same condition. Each participant also took part in 4 trials.         E- This means that another researcher would be able to repeat the study to see if similar results can be found.
    • Application:     P- One strength of this study is that it has real world application.     E- In long term memory it suggests that our STM encodes acoustically.    E- Applying Baddeley's findings has led to teachers/ professionals to promote the best learning strategies to improve memory e.g mindmaps.
    • Validity
      • Ecological    P- One weakness of Baddeley is that it lacks ecological validity.           E- Baddeley used a lab experiment which is an artificial setting.           E- This means the participant may have behaved unnaturally.
      • Experimental    P- Baddeley's study may lack experimental validity.            E- His participants were all from a psychology research unit.   E- Demand characteristics could have played a role. As the participants may have known about Psychology which could affect the results. This would affect the validity of the findings.
      • Task                 P- One weakness is it lacks task validity.            E- Use of stimulus material that was not naturalistic - use of word lists that sound alike/adjectives with similar meaning. The presentation of the lists four times.              E- Under normal conditions we would not be expected to remember these things in real life, so findings may lack validity.
