Brain scans indicate that there are two separate stores.
1 of 11
Sperling
Table of consonants. 1) Shown whole grid, only recall 3-4 2) Recall 3-4 letters for row that tune was playing. Suggested they could have recalled 9. STM picks up all letters but decay before recall.
2 of 11
Posner and Keele
Concluded that information is encoded visually before being translated into acoustic. B-B, B-b difference.

Jacobs and Miller
7+/- 2

Naveh-Benjamin & Ayres
Digit span is larger for countries that speak quicker. For example the English digit span is larger than Arabic.
5 of 11
Peterson and Peterson
Consonant trigram, asked to count back in 3's from a certain number, then asked to recall consonants after different times. Information decays very rapidly from STM, LTM/STM have different durations.
6 of 11
Nairne et al
Shown nouns and then asked to recall them in the correct order. Purer form of recall than Peterson.
7 of 11
Conrad
Acoustically similar and dissimilar. Concluded STM convert visual to acoustic as find it hard to distinguish.
8 of 11
Bahrick
Recall vs Recognition of former high school students. Duration of LTM can potentially be a life time.
9 of 11
Baddeley
Recall of acoustic vs semantically similar and dissimilar words. Supports existence of multi-store model as different stores deal with different codes.
10 of 11
Glanzer and Cunitz
1) Recall straight after shown. 2) Distracter task. Displaced last words on list. First letters had already been stored in LTM. Primacy and recency effect.
