2 limitations of STM
Badddley (1966) didn't use meaningful data
Jacob (1887) was conducted a long time ago and experiments in that time often lacked control of extraneous variables
Limitation of STM - Baddeley (1966) didn't use meaningful data
P: Baddeley (1966) didn't use meaningful data
E: Words had no personal meaning to Ps
C: Results of study limited applications coz difficult to generalise
Limitation of STM - Jacob (1887) was conducted a while ago and experiments back then often lacked control over extraneous variables
P: Jacob (1887) was conducted a while ago and experiments back then often lacked control over extraneous variables
E: Ps may have been distracted so not performed to full ability
C: Results not valid due to confounding variables
Strength of STM
Bharick (1975) had high external validity
Strength of STM - Bahrick (1975) had high external validity
P: Bahrick (1975) had high external validity
