- Long Term memory
- Duration
- Bahrick
- 392 ex high school students. 17-47 years old
- 1) Free recall of classmates. 2) Name to photo. 3) 50 photos. 4) Name recognition with no cue
- Within 15 years: 90% names recalled&60% on free recall. After 48 years: 75% names recalled using recognition tasks, 30% names free recall
- Long duration, can't access all information, but a cue helped reall this information.
- High mundane realism.
- High realiability
- Lack population validity, can't be generalised to other individulist or collectivist cultures
- Supporting Studies
- Shepard
- Waganaar and Groenweg
- Capacity
- Limitless
- Encoding
- Baddley
- Shown four lists of acoustically similar/dissimilar words; semantically similar/dissimilar
- Recall as many words after 10 minute interval of seeing the words
- After 10 minutes, PPS recalled the semantically similar words more rather than the other lists
- Lack ecological validity=lab experiment
- High realiability.
- Separate Stores
- Glanzer and Cunitz
- Shown list of words quickly and asked to recall
- Condition 1: Recall words straight after in any order
- Condition 2: Count back from 30 in 3's then recall words
- Serial position curve
- Remembered words at the beginning-Primacy effect.
- Words were rehearsed so put into LTM
- Remembered words at the end-recency effect.
- Words rehearsed for a little bit and stored in STM
- Remembered words at the beginning-Primacy effect.
- Lack ecological validity
- High realability
- Case Study
- HM had a operation where hippocampus and temporary lobe was removed causing him to not make new memories
- Damage to LTM so he was unable to move information from his STM to LTM so cannot retain information
- HM had a operation where hippocampus and temporary lobe was removed causing him to not make new memories
- Duration
