CHAPTER 8 Flashcards
the use of multiple
approaches and techniques to address a problem.
Converging Operations
is the fundamental unit of symbolic
knowledge, or knowledge of correspondence
between symbols and their meaning.
Concept
is a hierarchy of concepts; a category is a
concept with members.
Category
are groupings that occur
naturally in the world, like birds or trees
Natural categories
takes a different approach:
grouping things together not by their defining
features but rather by their similarity to an average
model of the category.
Prototype theory
are groupings that are designed
or invented by humans to serve particular purposes
or functions, like automobiles and kitchen
appliances.
Artifact categories
defining features something must have to be
considered an example of a category
Core
Tested the notion that we come
to understand the importance of defining features only as we grow older
Keil & Batterman
based view of meaning - holds that people understand & categorize concepts in terms of implicit theories or general ideas they have regarding those concepts
Theory/Explanation
Isolate features of a good
sport.
Feature-based
find characteristic features
of a good sport.
Prototype View
find some good examples
you have known in your life.
Exemplar View
use of experience to
construct an explanation for what makes
someone a good sport.
Theory-Based View
holds that certain categories have an
underlying reality that cannot be observed directly.
Essentialism
Beliefs about the characteristics of
groups are often associated with the devaluation of these groups & increased prejudice
Essentialist
suggest that knowledge is represented in our minds in the form of concepts that are connected with each other in a web-like form.
Semantic-network Models
is a web of elements of meaning
(nodes) in which the elements are connected with each other through links.
Semantic network
Defines each mammal by unique features (e.g., rabbit: fur, ears, hopping)
Feature-based theory
are elements that are typically
concepts.
Nodes
Organizes knowledge by comparing features of concepts directly
Semantic Features Theory
connection between the nodes
Relationships
