Sensory memory Multi store model
Duration: ¼ to ½ second Sequential model of memory:
Capacity: all sensory experience (v.
Information is detected by
Encoding: sense specific (e.g. different
stores for each sense. the sense organs and
enters the sensory memory.
Short term memory
Duration: 0-18 seconds If attended to this
information enters the short
Capacity: 7 +/- 2 items term memory.
Long term memory
Duration: Information from the STM is
Capacity:Unlimited transferred to the long-term
Encoding:Mainly Semantic (but
memory only if that
can be visual and auditory)
information is rehearsed.
If rehearsal does not occur,
then information is
forgotten, lost from short
term memory through the
processes of displacement

The working memory model was proposed by Baddeley &
Hitch (1974) as an alternative to the multi-store model of
memory. It challenged the concept of a single unitary store for
Central executive:controls and coordinates the operation of
two subsystems: the phonological loop and the visuospatial
Visual Spacial Sketchpad: deals with visual and spatial
information. Visual information refers to what things look like.
Phonological Loop: part of working memory that deals with
spoken and written material. It consists of two parts
1)phonological store (linked to speech perception) acts as an
inner ear and holds information in speech-based form (i.e.
spoken words) for 1-2 seconds.
2) articulatory control process (linked to speech production)
acts like an inner voice rehearsing information from the
Episodic Buffer: One of its important functions is to recall
material from LTM & integrate it into STM when working…read more
Mental arithmetics? Central executive
The area dominant for mental arithmetics as we
conceptualize the idea of numbers whilst also visually
presenting them in a way which is understandable and
Reading? Phonological loop
Children with impaired reading ability have reduced
memory spans and have difficulties in tasks which require
the manipulation of phonological information
