STM can hold 7±2 items
An item is an individual unit of information
True of False
True
Chunking
Method of increasing STM capacity
We can store few, but larger chunks
True or False
True
The serial position curve
Denotes the tendency to preferentially remember items from the beginning an end of a list of presented words
True or false
True
Primacy
Privileged remembering of first words in list
Semantic mistakes tend to be the most common errors found here
LTM involvement
True or False
True
Recency
Privileged remembering of last words in list
Acoustic mistakes tend to be the most common here
STM involvement
True or False
True
Why do we forget? STM
Decay - Loss after 15 to 30 seconds of non-rehearsal
True or false
True
Why do we forget? STM
Interference
Proactive interference
Previous information interfering with subsequent information
Retroactive interference
Subsequent information interfering with previous information
True or false
True
What is STM code?
Original memory model held that acoustic rehearsal, etc., was hugely important
Acoustic information
Can be chunked based on semantic, meaningful information
Visuospatial data
Information can be stored, pictured and manipulated using mental imagery
True or false
True
Limited capacity
Semantic code
Controls cognitively demanding tasks
Controls two slave systems
Selects, initiates and terminates automatic routines
CENTRAL EXECUTIVE
Limited capacity
Verbal code
Passive Phonological Store
(holds speech sounds)
Articulatory Control
(manipulates verbal info)
PHONOLOGICAL LOOP
Limited capacity
Visual code
Visual Cache
(holds visual form & colour)
Inner Scribe
(manipulates visuospatial info)
VISUOSPATIAL SKETCHPAD
Modality
independent
“Overflow
Storage”
EPISODIC
BUFFER

Evidence
Auditory processing task
Broca’s & Wernicke’s
Visual processing task
Occipital
Both (central executive?)
Prefrontal
True or False
True
Baddeley & Hitch - What is the central executive (brain)?
Prefrontal cortex
