- Long Term Memory
- Duration
- Up to a lifetime
- Coding
- Semantic
- Capacity
- Unlimited
- Duration
- Case Studies
- There is no study for capacity as it is hard to test it
- Bahrick (1975) Yearbook
- It was found that there was 90% accuracy in face and name recognition when tested within 15 years
- A field experiment was conducted in which 392 Americans aged between 17 and 74 were asked to take part in different tests
- Free recall test
- Participants were asked to recall as many names as they could from their graduate class
- Photo recognition test
- Participants were asked to identify former classmates by using 50 photos without being given a list of names
- Only some of the photos consisted of people from the class
- Participants were asked to identify former classmates by using 50 photos without being given a list of names
- Name recognition test
- Name and photo-matching test
- The responses of the participants were compared with their yearbooks that had all the names and photos
- It was also found that accuracy declined to 80% for name recongition and 40% for face recognition after 48 years
- There ws 60% accuracy after 15 years an only 30% after 48 years for free recall
- Uses meaningful stimuli to test subjects and they tested peoples memories from their own lives
- It is unclear whether the drop in accuracy is due to limitations of duration or general decline with memory
- Baddeley (1966) Word Lists
- Participants were shown a list of 20 words and asked to immediately recall what they were
- The words were from catagories that were acoustically similar and acoustically dissimilar as well as semantically similar and semantically dissimilar
- They had to recall the words again after 20 minutes
- The words were from catagories that were acoustically similar and acoustically dissimilar as well as semantically similar and semantically dissimilar
- The research was scientific
- It was found that words that were semantically similar were harder to recall
- It was concluded that the LTM relies on semantic coding
- The LTM can also use other forms of coding
- Participants were shown a list of 20 words and asked to immediately recall what they were
