Flashcards in Short and Long Term Memory Deck (11):
1

What are the 4 factors affecting the capacity of STM?

influence of LTM, reading aloud, rhythmic grouping, pronunciation time

2

Who conducted research onto the influence of LTM on the capacity of STM?

Bower and Winzenz 1969
as trials were repeated, recall easier

3

What are the 2 studies into pronunciation time and STM capacity?

Schweikert and Boruff 1986: consistently remember what can be said in 1.5-2 seconds
Naveh-Benjamin and Ayres 1986: Arabic and English, Arabic = digit span shorter, words longer to pronounce

4

What are the 3 factors affecting the duration of STM?

Maintenance rehearsal (items disappear when rehearsal prevented), deliberate intention recall, amount of information to be retained

5

Who conducted research on deliberate intention to recall and duration of STM?

Sebrechts 1989: 3 common nouns then unexpected recall test, info vanishes if conscious effort not made to retain it

6

Who conducted research on amount of information to be retained and the duration of STM?

Murdoch 1961: 1 or 3 three lettered words, accurate recall at 90% after 18s for single word (number of info chunks important)

7

What are the 2 factors which affect encoding in STM?

Sound of words (acoustic) or visual encoding

8

What are the 2 studies on sound of word and STM encoding?

Conrad 1964: STM relies on acoustic encoding
Baddeley 1966: compare acoustic with semantic similarity, STM relies on sound rather than mean

9

Who conducted research into visual encoding and STM?

Brandimonte 1992: visual coding can be used, similar images and asked to record in order, 2.7/6 named

10

What are the 3 factors affecting duration of LTM?

Childhood amnesia (children can't organise memories), how duration is measured: better recall via recognition, thorough learning

11

Who conducted research into thorough learning and LTM duration?

Bahrick and Hall 1991:
algebra and geometry, studied at high school or at college, college = high accuracy even 55 years later
