long term memory

Question 1

define long term memory.

Answer 1

memories that are taken from the STM to the LTM - these are longer lasting memories that last for months and years.

Question 2

what are the key differences between LTM and STM?

Answer 2

duration - how long info is stored.
capacity - how much info can be stored.
encoding - how the info is retained or learnt e.g acoustically.

Question 3

evaluating research of capacity of LTM.

Answer 3

• there are no studies that research the capacity of LTM, because there are endless amounts of info - capacity of LTM is unlimited.

Question 4

explain the procedure of the duration of the LTM.

Answer 4

Bahrik - high school year book study:
- tested 400 people (aged 17-74) on the memory of their classmates)
- asked to identify them from a series of photos in a high school year book.
- or asked to free recall the names of students in their class.

Question 5

state the results of this study.

Answer 5

photo recognition:
after 15 years - 90 percent accuracy.
after 48 years - 70 percent accuracy.

Question 6

how does the LTM encode?

Answer 6

semantically

Question 7

evaluation of encoding.

Answer 7

the LTM doesn’t exclusively use semantic - Frost found evidence of acoustic coding in the LTM.
