limitation of Baddeley's study was that it used quite artificial stimuli rather than meaning full material. the word list had no personal meaning to participants. this mean we should be cautious about generalising the findings to different tasks
1 of 6
Lack of validity- time span
Jacobs study was conducted a long time ago. early psychology often lacked adequate control. participants maybe distracted. not perform well. Maybe confounding variables(not controlled)
2 of 6
Not so many chunks
limitation Miller research may have overestimated the capacity of STM.Cowan (2001) reviewed other research and concluded that the capacity of STM was only 4 chunks. this suggests that the lower end of Miller's estimate is more appropriate than 7 item
3 of 6
Meaning less stimuli in STM study
limitation of Peterson(2x) study is stimuli material was artificial. trying to memorise constant syllables does not reflect most real life memory activities. this study lacks external validity
4 of 6
high external validity
strength Bahrick et al study has high external validity. real-life meaningful memories were studied. when studies on LTM have been conducted with meaningless pictures to be remembered recall was lower.
5 of 6
Limitation of Bahrick study (high school pictures)
is that the confounding variables are not controlled. such as Bahricks participants may have already looked through the year book photos and rehearsed the memories over the years.
