Conceptual Knowledge Flashcards
Conceptual knowledge
How we build our semantic memory; enables us to recognize objects and events to make inference about its properties
Concept
Mental representations used for a variety of cognitive functions
Categorization
The process by which things are placed into groups called categories
Categories are useful because they ______________
help understand individual cases not previously encountered
Categories involved “Pointers to knowledge”. What does this allow us to do?
It allows us to identify the special characteristics of a particular item
Caption
Knowing that something is in a category provides a great deal of information about it
Definitional approach to categorization
Coming up with a list of things that something needs to have to be a member of the category; DOES NOT WORK WELL
Family resemblance
Things in a category resemble one another in a number of ways, but do not have every single feature
The prototype approach
An abstract representation of the “Typical” member of a category
A prototype is the ___________ member of a category
Typical
A prototype is an ___________ people in the group but is not an actual _________________
average; member of the category
High prototypicality
A category member that closely resembles the category prototype
A high prototypicality for the group bird would be a ________
Robin, Blue Jay, or Sparrow
Low prototypicality
A category member does not closely resemble the category prototype
A low prototypicality for the group bird would be a _________
Penguin
There is a strong positive relationship between prototypicality and __________________________
Family resemblance
Low overlap = ______ Family Resemblance
Low
What is the typicality effect?
Prototypical objects are processed preferentially
Do we process high or low prototypical objects more rapidlY?
High
Sentence Verification Technique
Analyzing a sentence and saying if its true or false
Measured rate of reply
The questioner states “The apple is a fruit” and you reply with Yes in 200 ms. What does this examplify?
The sentence verification technique
The Exemplar Approach
The concept is represented by multiple examples (rather than a single prototype)
Examples in the exemplar method are ______________________
ACTUAL category members
