Memory

Question 1

Short Term Memory Summary

Answer 1

• lasts 18 seconds
• holds 7+- items
• needs rehearsal to go to LTM and be remembered

Question 2

Long Term Memory Summary

Answer 2

• Encoding is the input (puts sensory info into storage)
• unlimited
• mainly semantic info but also acoustic and visual

Question 3

What are the 3 reasons why we forget things?

Answer 3

• Displacement = new incoming info pushes out older info
• Interference = overwritten by new information
• Can’t find memory, lose link

Question 4

Sensory Register and role of attention

Answer 4

sensory register = stores all sensory information
if we pay attention to this info
its transferred from STM -> LTM
if not payed attention to, information decays

Question 5

Iconic Memory

Answer 5

• visual information

- lasts 1 second

Question 6

Echoic Memory

Answer 6

• auditory

- lasts a few second

Question 7

Role of Rehearsal

Answer 7

• repeating information holds it in STM longer

- if rehearsed for long enough gets transferred into LTM

Question 8

Strengths and Weaknesses of the Multi Store Model

Answer 8

+amnesia cases = show brain injury can damage LTM and STM remains intact, info can be lost and destroyed
+Murdock = you recall more words at beginning and end of word list than middle, you’ve had more time to repeat the words before they are displaces
-do not repeat every piece of info to remember it = meaningful
-unlikely there is only 1 type of LTM = amnesia, some LTM stays intact, some goes
