RESEARCH INTO CAPACITY IN STM

MILLERS MAGIC NU. 7 (AO1)
1. DIGIT SPAN TECHNIQUE (A01)
  1. (A01) According to Miller, most ppl have a digit span of 7 + or -2
  2. PROBLEM (AO2): Bower & Winzenz found it is difficult to exclude influence of LTM
  3. (A02) Miller suggested our immediate memory span (capacity) is determined by the number of chunks of info we can hold rather than individual letters or numbers
BADDLEY ET AL (AO1)
1. A: Baddley wanted to find out if capacity in STM was determined by pronouciation time rather than the number of items to be recalled (Did a study testing wether people could remember short words more than long words)
  1. P: Showed lists containing monosyllabic words & lists showing polysyllabic words
    1. FINDINGS:
      1. Pp's coulf recall significantly more short words than long words
      2. Pp's able to recall the nu. of words they could articulate in 2 secs
      3. Strong positive correlation between reading speed & memory span
NAVEH-BENJAMIN & AYRES (A02)
1. Tested the digit span technique with speakers of different languages
2. Found Arabic speakers had a lower digit span than English speakers
  1. Concluded only explanation for this is pronouciation time
    1. Findings support Baddley; Pronounciation time is more important than the number of items to be recalled
