STM and LTM
- Memory is the process
where information is
retained from the past
- Three types of memory:
- Sensory memory
- Visual and auditory
information which passes
through our senses briefly
from the result of
spontaneous decay
- Visual and auditory
information which passes
through our senses briefly
from the result of
spontaneous decay
- Short term memory
- STM has a limited
capacity and duration,
this means that we
can remember little
amounts of
information in a short
space of time
- STM has a limited
capacity and duration,
this means that we
can remember little
amounts of
information in a short
space of time
- Long term memory
- LTM has an
unlimited capacity
and is permanent,
this means that
large pieces of
information can be
stored for up to a
lifetime
- LTM has an
unlimited capacity
and is permanent,
this means that
large pieces of
information can be
stored for up to a

- Sensory memory
- STM and LTM
differ in terms of:
- Duration: the
time in which the
memory lasts for
- Capacity: the
amount of
information
the memory
can hold
- Duration: the
time in which the
memory lasts for
- Research: Peterson and Peterson
1959) investigated the duration of
STM
- Method: Participants were shown
nonsense triagrams and were asked to
recall after 3,6,9...up to 18 seconds.
During the pause, they were given an
inference task which prevented them
from repeating the letters in their heads
- Results: After 3 seconds,
participants were able to
recall 80% of triagrams
correctly, meanwhile after
18 seconds only 10% could
correctly recall the triagrams
- Conclusion: After 18 seconds,
little information can stay in STM
when rehearsal is prevented
- Evaluation: The Peterson and Peterson experiment is a lab
experiment which causes it to have low ecological validity, this
means that it doesn't really appeal to real life situations.
Furthermore, the nonsense triagrams are artificial which also
lacks in terms of the validity of the experiment. However, as the
experiment is lab-based any variables can be strictly monitored.
