Chapter 7 Flashcards
the form for what you
know in your mind about things, ideas, events, and so
on, in the outside world
knowledge representation
two kinds of knowledge structures
Declarative knowledge
Procedural knowledge
observation
of one’s mental and emotional
processes.
Introspectionist Approach-
- deduce logically
how people represent knowledge
Rationalist Approach
Ways to observe how we represent
Knowledge in our
minds
Introspective approach
Rationalist Approach
refers to facts
that can be stated, such as the date of
your birth, the name of your best friend,
or the way a rabbit looks.
Declarative knowledge
refers to
knowledge of procedures that can be
implemented
Procedural knowledge
There are two main sources of
empirical data on knowledge
representation:
-Standard laboratory experiments
-neuropsychological studies
experimental work, researchers
indirectly study knowledge
representation because they
cannot look into people’s minds
directly
Standard Laboratory Experiments
(1) they observe how the normal brain responds to
various cognitive tasks involving knowledge
representation.
(2) they observe the links between various deficits in
knowledge representation and associated pathologies
in the brain.
Neuropsychological studies
Pictures in
Your Mind
Mental
Imagery
The mental representation of things that are not
currently seen or sensed by the sense organs
IMAGERY
Use both pictorial and verbal codes
for representing information in our
minds
DUAL-CODE THEORY
TWO CODES ORGANIZE INFORMATION INTO
KNOWLEDGE THAT CAN BE ACTED ON, STORED SOMEHOW, AND LATER
RETRIEVED FOR SUBSEQUENT USE.
- Analog codes
2.Symbolic code
resemble the objects they
are representing.
Analog codes
it’s a form of knowledge
representation that has been chosen
arbitrarily to stand for something that
does not perceptually resemble what is
being represented.
Symbolic code
Its storing Knowledge
as Abstract
Concepts:
Propositional
Theory
suggests that we do not store mental
representations in the form of images
or mere words.
PROPOSITIONAL THEORY
—secondary and derivative
phenomena that occur as a result of other
more basic cognitive processes.
Epiphenomena
to express the
underlying meaning of a relationship.
