Memory Flashcards
Cowan (2001)
STM is limited to 4 chunks.
Vogel et al. (2001)
STM for visual stimuli limited to 4 items.
Simon (1974)
Size of chunks affects how many can be remembered.
Jacobs (1887)
Digit span test, it is easier to recall digits than letters
+
Recall improves with age.
Reitman (1974)
Peterson and Peterson (1959) actually found evidence for displacement, not decay.
Nairne et al. (1999)
Items can be remembered in STM for 96 seconds.
Brandimote et al. (1992)
Encoding for STM can also be visual.
Wickens et al. (1976)
Encoding for STM can also be semantic.
Frost (1972)
Encoding for LTM can also be visual.
Nelson and Rothbart (1972)
Encoding for LTM can also be acoustic.
Miller (1956)
7 +/- 2 is the magic number of items that can be recalled in STM.
Peterson and Peterson (1959)
Trigram experiment (THX 512, for example): Recall was 90% accurate after 3 seconds but only 2% after 18 seconds.
Bahrick et al. (1975)
Photo memory test. LTM decreases over time.
Baddeley (1966)
STM is mainly encoded acoustically whilst LTM is mainly encoded semantically.
Beardsley (1997)
The prefrontal cortex is active during STM.
Squire et al. (1992)
The hippocampus is active during LTM.
Scoville and Milner (1957) [case study of HM]
HM had his hippocampus removed and could not form new LTMs.
Craik and Lockhart (1972)
Deep processing is more important than maintenance rehearsal for forming lasting memories.
Craik and Tulving (1975)
Participants remember nouns better when they have to fit them into sentences (deep processing).
Logie (1999)
STM relies on LTM and therefore cannot come before it in the MSM.
Ruchkin et al. (2003)
Brain scans showed that LTM is used for STM tasks as Logie (1999) had said it would.
Hitch and Baddeley (1976)
Dual task performance supports the WMM.
Shallice and Warrington (1970) [case study of KF]
KF lost STM for auditory but not visual information.
Trojano and Grossi (1995) [case study of SC]
SC was fine apart from being unable to learn word pairs out loud.
Farah et al. (1988) [case study of LH]
LH performed better on spatial tasks than visual imagery tasks.
Eslinger and Damasio (1985) [case study of EVR]
EVR performed well at reasoning tasks but not decision making, showing that there may not be a singular Central executive.
Baddeley et al. (1975)
Phonological loop can only hold 2 seconds-worth of information.
