Schemas and Scripts
schema—generalized knowledge about a
situation, an event, or a person
Schema theories are especially helpful
when psychologists try to explain how
people process complex situations and
events.

Schemas and Scripts
Background on Schemas and Scripts
Schema theories propose that people
encode "generic" information about a
situation, then use this information to
understand and remember new examples
of the schema.
"This is just like what happened when . . ."

Identifying the Script in Advance
Scripts are recalled more accurately if
identified in advance.
Demonstration 8.4: Trafimow & Wyer (1993)

(continued)
• Event recall was higher when the scriptidentifying event was presented first,
rather than last.
Events in a sequence are much more
memorable if you understand—from the very
beginning—that these events are all part of a
standard script.

Schemas and Memory Selection
Demonstration 8.5: Brewer and Treyens
(1981)
• recall objects from an office waiting room
• highly likely to recall objects consistent
with "office schema"
• "remembered" items that were not in the
room, but were consistent with "office

Schemas and Memory Selection
General Conclusions about Schemas and
Memory Selection
1. If the information describes a minor
event—and time is limited—people tend to
remember information accurately when it is
consistent with a schema (e.g., the desk
and the chair in the ‘‘office’’).

2. If the information describes a minor

remember information that is inconsistent
with the schema (e.g., the wine bottle and

Schemas and Memory Abstraction
The Constructive Approach
Bransford and Franks (1971)
• listen to sentences from several different
stories
• recognition test including new items
• People were convinced that they had seen
these new items before (false alarm).

The Constructive Approach
Bransford and Franks (1971) (continued)
• False alarms were particularly likely for
complex sentences consistent with the
original schema.
• False alarms were unlikely for sentences
violating the meaning of the earlier
sentences.

The Constructive Approach
constructive model of memory—People

sentences in order to construct larger ideas;
later, they cannot untangle the constructed
information from the verbatim sentences.

The Pragmatic Approach
pragmatic view of memory—people pay
attention to the aspect of a message that is
most relevant to their current goals
1. People know that they usually need to
accurately recall the gist of a sentence.
2. They also know that they usually do not
need to remember the specific wording of
the sentences.

3. However, in those cases where they do
need to pay attention to the specific
wording, then they know that their verbatim
memory needs to be highly accurate.

The Pragmatic Approach
Murphy and Shapiro (1994)—Insult Study
• Correct recognition was higher for
sentences from the sarcastic condition than
for sentences in the bland condition.

sentences than sarcastic sentences
• more accurate verbatim memory for the
sarcastic version than for the bland version

Schemas and Memory Abstraction
The Current Status of Schemas and
Memory Abstraction
• two compatible approaches
• In many cases we integrate information into
large schemas.
• In some cases we know that specific words
matter and pay close attention to precise
wording.

Schemas and Memory Integration
memory integration—background knowledge
encourages people to take in new information in
a schema-consistent fashion
People may remember schema-consistent
information, even though it was not part of the
original stimulus material.
Schemas do not always operate. Factors such as
delay before testing and task complexity
influence the use of schemas.

Schemas can influence our inferences when
we are reading ambiguous or unclear material.

Conclusions About Schemas
Schemas often influence our cognitive
processes:
• in the initial selection of material
• in remembering visual scenes
• in abstraction
• in the final process of integration

Conclusions About Schemas
However:
1. We often select material for memory that
is not consistent with our schemas.
2. We may sometimes remember that we
saw only a portion of an object, rather
than the complete object.
Cognition, 8e by Margaret W. Matlin

Conclusions About Schemas
However:
3. We frequently recall the exact words of
a passage as it was originally, rather
than storing an abstract memory.
4. We may keep the elements in memory
isolated from each other, rather than
integrating these elements together.

Conclusions About Schemas
In summary, both schemas (top-down
processing) and unique features of each
stimulus (bottom-up information) influence
memory.
