Long-Term Memory
- Capacity- possibly unlimited
- Duration- measured in hours, days and years
- Shepard (1967)
- showed ppt 612 memorable pictures, one at a time
- an hour later, they were shown
some of these pictures among a
set of others
- showed almost perfect recognition
- showed almost perfect recognition
- an hour later, they were shown
some of these pictures among a
set of others
- 4 months later, they were still
able to recognise 50% of the
photographs
- showed ppt 612 memorable pictures, one at a time
- Bahrick (1975)
- asked people of various ages to put names
to the faces from their high school year
books
- free recall accuracy dropped from
50% at 3 months to 20% at 40+
years
- recognition of names and pictures and matching of names and pictures
remained high (85-90%) for all retention intervals
- dropping sharply to
about 75% in the
eldest age group
- dropping sharply to
about 75% in the
eldest age group
- in picture-naming
condition- about
70% accuracy at 3
months after
graduation, 60%
after 5 years and
20% after 40+ years
- free recall accuracy dropped from
50% at 3 months to 20% at 40+
years
- asked people of various ages to put names
to the faces from their high school year
books
- Shepard (1967)
- Encoding- semantic
- Baddeley (1966a and 1966b)
- tested effects of acoustic and semantic similarity
on short-term and long-term recall
- gave ppts list of
words that were
acoustically
similar and
dissimilar and
semantically
similar and
dissimilar
- found ppts found it harder to remember
acoustically similar words for STM
semantically similar words in LTM
whereas it was easier the other way
around
- suggesting LTM stores information semantically

- tested effects of acoustic and semantic similarity
on short-term and long-term recall
- encoding in LTM may not just be semantic
- Frost (1972)
- showed LT recall was related to
visual and well as semantic
categories
