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.- ABaddeley

2Both Baddeley (1966) and Peterson & Peterson (1959) have:
- ALow external validity
- BHigh external validity
3Despite its old age (and therefore lack of control of extraneous variables), Jacobs (1887) has had its results confirmed in other research.
- AVerdadero

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.

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.- Ahigh
