Q

What happens if attention is not paid to sensory information?

16
Q

What support is there for STM and LTM being qualitatively different?

A

BADDELEY’S coding research = different encoding processes

17
Q

How does research into coding, capacity and duration help support this model? msm

A

They all show how STM and LTM are independent, as they work very differently

18
Q

What clinical evidence is there to challenge this? msm

A

KF - brain damage patient struggled to process verbal info but not visual info
= STM is non-unitary

19
Q

How has the MSM’s rehearsal process been challenged?

A

CRAIK & WATKINI found that there are different types of rehearsal - elaborative rehearsal is needed for info to pass into LTM, not the amount like stated in MSM
