What is Memory?
2
Understanding Memory
1. Length of storage
2. Type of information to be
remembered
3. The stages involved in remembering
4. Recall and recognition
5. Explicit and implicit memory
6. Retrospective and prospective
memory

Understanding
Memory
Length of storage
◦ Sensory Memory
◦ Iconic Memory
◦ Echoic Memory
◦ Working Memory
◦ Short-term or Immediate Memory
◦ Phonological & visuo-spatial
◦ Long-term Memory
◦ Delayed Memory
◦ Recent Memory
◦ Remote Memory
Sensory Memory
Iconic Memory (vision)
•Capacity: Essentially that of the visual system
•Duration: About 0.5 to 1.0 seconds
•Processing: None beyond raw perceptual processing
Echoic Memory (hearing}
•Capacity: ?
•Duration: About 4 to 5 seconds
•Processing: None beyond raw perceptual processing
Short-term memory (STM) a.k.a. working memory
•Capacity: About 7 ± 2 "chunks" of information
•Duration: About 18 to 20 seconds
•Processing: information is often encoded verbally
Long-term memory (LTM)
•Capacity: Virtually unlimited
•Duration: Up to a lifetime
•Processing: Information is organized according to
meaning and is associatively linked

Understanding Memory
Type of information to be
remembered
◦ Declarative / Explicit Memory
◦ Semantic Memory (facts)
◦ Autobiographical Memory
◦ Episodic Memory (events)
◦ Non-declarative / Implicit Memory
◦ Procedural Memory
◦ Classical Conditioning
◦ Non-associative learning
5
Memory Disturbances
Psychological description
◦ Length of storage
◦ Immediate / Delayed / Recent / Remote
◦ Type of information lost
◦ Events / Facts / Skills
◦ Stages
◦ Encoding / Storage / Retrieval
6
Memory Disturbances
Clinical description
◦ Amnesia / Paramnesia
◦ Transient / Persistent
◦ Acute / Chronic
◦ Retrograde / Anterograde
◦ Symptom / Syndrome / Disorder
◦ Psychological / Organic
◦ Selective / Global
7
Recall Test
Recognition
◦ Identifying that the information has been
seen/heard before
Recall
◦ Reproducing the information from memory
1. Free recall
2. Cued recall
◦ the retrieval of memory with the help of cues,
which can be category, first letter, semantic etc.

Digit/symbol coding
Now look down here where the squares have numbers in the top but the squares at the bottom are empty
In each of the empty squares, put the mark that should go like this… (examiner puts in the first 4 symbols)

Logical memory
Two short stories are
presented orally
The examinee is asked
to retell each story
from memory
immediately after
hearing it
The examinee is asked
to retell both stories
Then the examinee is
asked yes/no
questions about both
stories
Logical Memory I Logical Memory II
narrative
11
Verbal Paired Associates
The examiner read 10 or
14 pairs of words
Examiner read the first
word of each pair, and
examinee provide the
corresponding word
The examinee is orally
presented with the first
word. Tasks: free, cued
and delayed recall.
VPA-I VPA-II
associated word pairs
12
Interpretive Considerations:
LM and VPA
Both (LM & VPA) measure aspects of semantic and auditory memory
Presentation of information is organized/ meaningful for LM and
unorganized for VPA.
VPA requires single word responses; LM requires longer, more
cohesive responses.
VPA is multi-trial learning measure. For Adult Battery, LM represents
single-trial learning ability
13
Visual Reproduction
A series of 5
designs is shown,
one at a time, for
10 seconds each
The examinee is
asked to draw the
design from
memory
The examinee is
asked to draw the
designs from
memory in any
order
The examinee is
asked to choose
which of 6 designs
on a page matches
the original design
The examinee is
asked to draw the
designs while
looking at them
(optional task)
VR-I VR-II
nonverbal visual stimuli
14
Design
The examiner shows a
grid with 4–8 designs for
10 seconds
The examinee selects the
designs from a set of
cards and places them in
a grid in the same place
as previously shown
The examinee is asked to
recreate the pages
shown with the cards
and grid
The examinee is shown
a series of grids and
asked to select the two
designs that are correct
Design-II
unfamiliar visual stimuli
Design-I
15
Interpretive Considerations:
VR and DE
Both measure aspects of
visual details and spatial
memory.
Response process for VR
includes more visual-
construction and fine motor
abilities than DE.
16
Spatial Addition
Assesses visual-spatial working
memory using a visual addition task.
Examiner shows the examinee,
sequentially, two grids with blue and
red circles. [5 sec.]
Then, examiner asks examinee to add
or subtract the location of the circles
based on a set of rules.
17
Symbol Span
This subtest assesses visual
working memory using novel
visual stimuli.
The examinee is briefly shown a
series of abstract symbols on a
page and then asked to select
the symbols from an array of
symbols, in the same order they
were presented on the previous
page
18
Interpretive Considerations:
SA and SP
SA taps spatial location memory and the ability to
compare spatial images.
SP is highly focused on recall of visual details and the
sequence of the images must also be maintained in
memory. SA uses a free recall format.
SP uses a recognition memory format
19
Auditory-Verbal Learning Test
•Examiner reads a list of
15 words (List A)
•Free recall
•Trial I, II, III, IV, and V
Learning
•Examiner reads a list of
15 words (List A)
•Free recall
Interference
•Immediate free recall
(trial VI)
•Delayed recall (trial VII)
Post-interference
recall
•identify the original
words among 50 words
from A and B lists plus
words that are related
(semantic/ phonetic)
Recognition
20
Auditory-Verbal Learning Test
Uses 15-word lists (A, B and C)
Measures learning and retention
1. Immediate word span under
overload (trial I)
2. Final acquisition level (trial V)
3. Total acquisition (total trial I to V)
4. Immediate recall (trial VI)
5. Delayed recall (trial VII)
6. Recognition
