MEMORY SUMMARY TABLE
Memory topic Key information Evaluation issues
Coding, capacity and Coding > Baddeley (words) Strength - separate
duration STM - acoustically memory stores
LTM - semantically Limitation - artificial
Capacity > Jacobs (digit situation
span) Strength - Jacobs, valid
Digits - 9.3, Letters - 7.3 study (replication
Capacity > Miller (chunking) Limitation - Miller,
7 +/- 2 overestimation (not so many
Duration > STM, Peterson chunks)
Consonant syllable, 18s Limitation - artificial stimuli
Duration > LTM, Bahrick Strength - high external
Photo recognition, lifetime validity
Multi store model of Sensory register Strength - research support
memory Coded - senses (Baddely, sep memory
Capacity - high stores)
Duration - 0.5s Limitations - artificial
Short term memory stimuli often used in
Coded - acoustically research + evidence of
Capacity - 7 +- 2 items more than one STM store +
Duration - 18-30s elaborative rehearsal
Long term memory needed to transfer from
Coded - semantically STM to LTM
Capacity - limitless
Duration - lifetime
Types of long term Episodic memory Strengths - clinical
memory Knowledge of personal evidence (HM/Clive
events Wearing) + real world
Procedural memory application
Knowledge of how to Limitations - clinical studies
perform tasks lack control of variables +
Semantic memory conflicting neuroimaging
Knowledge of the world research (location of ltm
types)
Working memory model Central executive Strengths - clinical
Monitors incoming data, evidence (KF, separate
focuses and divides limited visual and acoustic stores) +
attention, and allocates dual task performance
slave systems studies (support idea of
Phonological loop separate VSS)
Auditory information, + how Limitations - clinical studies
it arrives lack evidence (may have
Phonological store - stores affected different systems) +
words you hear lack of clarity for the central
Articulatory process - executive
