Memory Flashcards
Akinson and Shiffrin
Developed multi-store model of memory
Consists of sensory register, STM & LTM
Bahrick et al
Found: participants were able to recognise names/faces of class mates up to 50 years go .˙. shows LTM is infinite
Tulving
Proposed 3 types of LTM:
Episodic (recalling events)
Semantic (Knowledge of world; facts)
Procedural (memory for actions/skills)
Baddeley and Hitch
Developed WMM: explained STM is organised/functions
4 Components:
Central executive (attention process, allocates slave systems)
Phonological loop (Store and articulatory process, deals w/ auditory info)
Visuo-spatial sketchpad (visual stores/spatial info)
Episodic Buffer (maintains sequences, organises info)
Loftus and Palmer
Participants watched films of car accidents
Different incident, asked about the how fast the car was going “hit”, “collied”, “smashed”, “bumped”
Found: Smashed/collied = was going higher speed
.˙. Leading questions effect EWT
Johnson and Scott
Participants thought they were part of a lab study Experienced incident 1st hand 1st condition: man & knife 2nd condition: man & pen Pen: 49% = recognise mans face Knife: 33% = recognise mans face .˙. weapon focus has an effect on EWT
Pickel (contradicts Johnson and Scott)
Similar experiment but in a hair salon used: scissors, handgun, wallet and raw chicken
Results: accuracy poorer w/ handgun and raw chicken
due to unusualness of the object rather than anxiety of weapon itself
Sensory Register
Consists of several sensory stores
each holding information very briefly when stimuli is presented.
Each register has limited capacity
Episodic Memory
long-term memory store for personal events
Semantic Memory
long-term memory store for our knowledge of the world
Procedural Memory
long-term memory store for our knowledge of how to do things
Working memory model
representation of short-term memory. suggests STM is a dynamic processor for diff types of info
Central executive
co-ordinates activities of the three subsystems in memory
Phonological loop
processes info in terms of sound
Visuo-spatial sketchpad
processes visual and spatial info in mental space called ‘inner eye’
