COGNITIVE LEARNING AND MEMORY
MULTIPLE STORE MODEL OF MEMORY
This is a "black box" model which concentrates on external inputs
and the consumer behavior outputs that seem to ensue from them.
- Sensory
- preattention stage
- brief analysis to determine if additional processing capacity
should be devoted to stimulus
- Short-Term
- where information is actively processed
- Long-Term
- where information is stored after encoding for later retrieval
encoding:
the process of transferring information from short- to long-term
memory for permanent storage
retrieval:
the process of accessing information stored in long-term memory
so that it can be utilized in short-term memory
MULTIPLE STORE MODEL OF MEMORY
- Sensory Register(s)
- the immediate impression caused by the firing of the sensory
nerve cells
- preattentive: determines if additional capacity should be
allocated to processing stimulus information
- Short-Term Memory (STM)
- a.k.a. working memory
- where information is temporarily stored while being processed
- rehearsal can be used to refresh STM, as when silently
repeating a phone number prior to dialing
- Long-Term Memory (LTM)
- essentially unlimited in capacity
- can store information permanently
MULTIPLE STORE MODEL OF MEMORY
- Sensory Register(s)
- briefly hold (fractions of seconds) information inputs
- very limited in capacity
- Short-Term Memory (STM)
- a.k.a. working memory
- can hold information for tens of seconds
- used for integrating inputs and LTM in"thinking"
- limited in capacity
- Long-Term Memory (LTM)
- holds information for long periods of time (years)
- "unlimited" capacity
MILLER'S LAW:
Expanding the Limits of STM
Recall:
STM seems to be capacity limited at around seven bits of information,
plus or minus two
Chunking:
the mental process of grouping together several pieces of
information and treating them as a single set
A chunk uses about the same amount of capacity as a bit.
INFORMATION OVERLOAD:
when more information is received than can be processed in
short-term memory
INVOLVEMENT AND SHORT-TERM MEMORY CAPACITY
Higher involvement
. . . . . ====> higher arousal
. . . . . . . . . . . . . . . . . ====>higher capacity
Lower levels of involvement suggest lower capacity for information
processing.
What are the implications for advertising?
LONG TERM MEMORY
Testing LTM:
recognition task
person is asked to judge if information that is presented has
been seen previously
recall task
person must retrieve the information from long-term memory
Consideration Set (evoked set)
the set of alternative brands that a consumer regards as acceptable
for further consideration; ones which are recalled (enter STM)
LONG-TERM MEMORY
Two basic types of interest to consumer researchers:
Episodic
refers to memories associated with events or episodes in our
experiences
Semantic
refers to facts and other information that we store through
language; verbal material
- -e.g., how to do addition
(Note: Mowen also distinguishes between semantic and visual memory.
The notion of an associative network suggests that we do not simply
store most information in a language format: the storage is in a
holistic form much like a laser hologram. Mowen notes that pictorial
information is recognized and recalled more readily than verbal information.)
LONG-TERM MEMORY
Schema:
a cognitive structure that represents a person's knowledge about a
given object or behavior
an organized set of expectations held by a person about an object
Script:
an organized sequence of behavioral events
Information salience:
refers to the level of activation of a stimulus in memory
NETWORK ORGANIZATION OF LTM
Node
an LTM center that represents a word, idea, or concept
Linkage
the means of association between two nodes
Activation
an energy flow into particular nodes to bring them into STM
Retrieval
the process of locating the proper nodes in LTM and bringing
them into STM
Encoding
the process of categorizing a stimulus and choosing a storage
location for it in LTM
ATTENTION
the momentary focusing of our information processing capacity
on a particular stimulus
One school of thought is that attention lies on a continuum,
anchored by processes that are:
- controlled
- effortful
- consume much capacity
- automatic
- "effortless"; "mindless"
- consume little capacity
- occur without conscious control
- a.k.a. preconscious attention
STRENGTH OF LEARNING
- Importance (effort)
- Reinforcement (consequences)
- Repetition (refresh)
- Imagery (multiple memories)
COGNITIVE PROCESSING TERMS
- Activation
Stored cognitive representations are made available for retrieval from
memory for processing.
- Spreading Activation
Activation of one representation will spread to and activate other
representations with which it is associated.
- Capacity Limits
The cognitive processing system has a finite limit in the amount of
information that can be processed at one time.
- Automatism
As cognitive processes are practiced (i.e., the limited capacity system
is used), they eventually require less conscious control and less capacity.
FORGETTING
- retroactive interference
after old material has been learned, new material interferes with
the retrieval of old material from memory
- proactive interference
material learned prior to the new material interferes with the
learning of the new material
- advertising pulsing
forgetting occurs rapidly at first, and then levels off:
why do advertisers often use a pulsing strategy?
