  1. 1[blank_start]Baddeley[blank_end] ([blank_start]1966[blank_end]) studied the difference in coding between STM and LTM. They found that STM was coded [blank_start]acoustically[blank_end], and LTM was coded [blank_start]semantically[blank_end].

    [blank_start]Jacobs[blank_end] ([blank_start]1887[blank_end]) studied the capacity of STM. They found that it holds an average of [blank_start]9.3[blank_end] numbers and [blank_start]7.3[blank_end] letters.

    [blank_start]Miller[blank_end] ([blank_start]1956[blank_end]) noted that things come in groups of 7. He found that the span of STM is 5-9 items, but that this can be improved by [blank_start]chunking[blank_end].
    [blank_start]Peterson & Peterson[blank_end] ([blank_start]1959[blank_end]) studied the duration of STM. gave 24 students a trigram to remember and limited rehearsal through counting. Students recalled [blank_start]80%[blank_end] of the syllables correctly with a 3 second interval, or [blank_start]3%[blank_end] with 18 second interval. This suggests that STM without rehearsal is about [blank_start]18-30[blank_end] seconds.

    [blank_start]Bahrick et al[blank_end] ([blank_start]1975[blank_end]) studied the duration of LTM. They tested [blank_start]392[blank_end] Americans aged between [blank_start]17-74[blank_end].
    1. Recognition test: 50 photos from participants' high school yearbook.
    2. Free recall test: Participants listed names of their graduating class.
    Participants tested 48 years after graduation were about [blank_start]70%[blank_end] accurate. Free recall was [blank_start]less[blank_end] accurate.

  2. 2Both Baddeley (1966) and Peterson & Peterson (1959) have:
    1. ALow external validity
    2. BHigh external validity
  3. 3Despite its old age (and therefore lack of control of extraneous variables), Jacobs (1887) has had its results confirmed in other research.
    1. ATrue
    2. BFalse
  4. 4[blank_start]Cowen[blank_end] ([blank_start]2001[blank_end]) disagreed with Miller (1956), believing the capacity of STM to be only 4 chunks.
    1. ACowen
    2. B2001
  5. 5Bahrick et al (1975) has [blank_start]high[blank_end] external validity, as the information was [blank_start]meaningful[blank_end].

    Shepard ([blank_start]1967[blank_end]) shows that recall rates are [blank_start]lower[blank_end] with meaningless pictures.
    1. Ahigh
    2. Bmeaningful
    3. Clower
    4. D1967
