2. is the processes by which information is
encoded, stored, and retrieved. Encoding
allows information that is from the outside
world to reach our senses in the forms of
chemical and physical stimuli.
The process of acquiring information
drjma 2/15/2013
3. 1. first stage we must change the information so
that we may put the memory into the encoding
process.
2. Storage is the second memory stage or
process.
This entails that we maintain information over
periods of time.
3. Finally, the retrieval.
This is the retrieval of information that we have
stored.
We must locate it and return it to our consciousness.
Some retrieval attempts may be effortless due to the
type of information.
drjma 2/15/2013
4. Encoding or registration
(receiving, processing and combining of
received information)
Storage (creation of a permanent record
of the encoded information)
Retrieval, recall or recollection
(calling back the stored information in
response to some cue for use in a
process or activity)
drjma 2/15/2013
5. Sensory memory: referring to the
information we receive through the senses
Short term memory: is the storage
mechanism that temporarily holds current
or recent information for immediate or
short term use.
Long term memory: is relatively permanent
and practically unlimited in terms of its
storage capacity

briefly stores an image which has been perceived
for a small duration.
Echoic memory

permanent changes in neural connections

The hippocampus is essential (for learning
new information) to the consolidation of
information from short-term to long-term
memory,
Without the hippocampus, new memories are
unable to be stored into long-term memory

multiple subcomponents, such as:

mechanism by which information
eventually reaches long-term storage

17. 1. Recognition memory tasks require individuals
to indicate whether they have encountered a
stimulus
such as a picture or a word
2. Recall memory tasks require participants to
retrieve previously learned information.
For example, individuals might be asked to
produce a series of actions they have seen
before or to say a list of words they have heard
before.
drjma 2/15/2013
18. 1. Declarative memory
requires conscious recall, in that some conscious
process must call back the information.
It is sometimes called explicit memory, since it
consists of information that is explicitly stored
and retrieved.
2. Procedural memory
Aka “implicit memory”
drjma 2/15/2013
19. semantic memory, which concerns facts
taken independent of context
episodic memory which concerns information
specific to a particular context, such as a
time and place.
Autobiographical memory - memory for
particular events within one's own life - is
generally viewed as either equivalent to, or a
subset of, episodic memory.
Visual memory is part of memory preserving
some characteristics of our senses pertaining
to visual experience.

time-based prospective remembering.

paired comparison procedure (relies
on habituation):
infants are first presented with pairs of visual
stimuli
Operant conditioning technique:
infants are placed in a crib and a ribbon that is
connected to a mobile overhead is tied to one of
their feet
drjma 2/15/2013
25. Deferred imitation technique:
an experimenter shows infants a unique
sequence of actions (such as using a stick to push
a button on a box) and then, after a delay, asks
the infants to imitate the actions.
Elicited imitation technique:
is very similar to the deferred imitation
technique; the difference is that infants are
allowed to imitate the actions before the delay

26. Paired associate learning - when one learns
to associate one specific word with another.
Free recall - during this task a subject would
be asked to study a list of words and then
sometime later they will be asked to recall
or write down as many words that they can
remember.
drjma 2/15/2013
27. Detection Paradigm- Individuals are shown a
number of objects and colors samples, during
a certain period of time.
Recognition - subjects are asked to
remember a list of words or pictures, after
which point they are asked to identify the
previously presented words or pictures from
among a list of alternatives that were not
presented in the original list.
Detection Paradigm- Individuals are shown a
number of objects and colors samples, during
a certain period of time.

anatomy of memory such as:
• Hippocampus

• Retention
• Reactivation
• reconstruction of the experience-independent internal
representation

normal aging from the kind of memory loss
associated with a diagnosis of Alzheimer's

36. Recall:to recall means to supply or
reproduce facts or information.
Recognition: is usually superior to recall.
E.g. multiple-choice test because you
recognize correct answer.
Relearning: is typically the most sensitive
measure of memory. It may seem that
learning algebra, history, or a foreign
language is wasted if you don't use the
knowledge immediately
drjma 2/15/2013
37. Knowledge of results: learning proceeds best
when feedback, that allows you to check
your progress.
Recitation: recitation means summarizing
aloud while you are learning.
drjma 2/15/2013
38. Selection: if you boil down the paragraphs in most
textbooks to one or two important terms or ideas, your
memory will be more manageable.
Rehearsal: the more you rehearse as you read, the
better you will remember it.
Cues the best memory cues (stimuli that aid retrieval)
are those that were present during encoding.
drjma 2/15/2013
39. Whole versus part learning: Generally, it is better
to practice whole packages of information rather than
smaller parts.
Organization: simple reordering or organizing can be
helpful.
Serial position whenever you must learn something
in order, be aware of the serial position effect.
drjma 2/15/2013
40. Spaced practice: to keep boredom and fatigue
to a minimum, try alternating short study sessions
with brief rest period.
Over learning: after you have learned material
well enough to remember it once without error,
you should continue studying.
Extend how long you remember: when you are
learning new information, test yourself repeatedly.
drjma 2/15/2013
41. Hunger: People who are hungry almost always
score lower on memory tests.
Sleep: remember that sleeping after study
reduces interference.
Review : if you have spaced your practice and
overlearned, reviewing shortly before an exam help to
remember details.
drjma 2/15/2013
43. Encoding - transforming incoming information into a usable form
state-dependent learning - fact that a bodily state that exists
during learning can be a strong cue
Elaborative rehearsal – concentrates on the meaning of
information you want to remember
proactive interference -The tendency for prior learning to inhibit
recall of later learning
Echo - Things that are briefly heard in the sensory register.
Recognition –
Implicit memory – memories outside of conscious awareness.
Icon - image that persists for about one-half second after being
seen.
Hippocampus - part of the brain that functions as a "switching
station" between the STM and LTM.

44. Limitless - storage capacity of long-term memory.
Psychologists have concluded that long-term memories fall
into the following two categories - procedural memory and
fact memory.
Decay theories of memory loss seem to be most
appropriate for: short-term memory and sensory memory.
sensory memory - first step in placing information into
memory storage.
semantic memory - general knowledge section of the
intelligence test for adults
Storage - process of holding information
Working memory is associated with short term memory
