High Typicality
Category member closely resembles category prototype, a "typical" member
Prototype approach to categorization
Membership in a category is determined by comparing the object to a prototype that represents the category
Is a prototype a member of the category?
No, it is an "average" representation of the category
During an experiment using the Sentence verification technique, participants are presented with 2 statements: "An apple is a fruit" and "A pomegranate is a fruit" Which statement would be responded to faster, and why?
"An apple is fruit", because it has a higher prototypically in the category of fruit compared to pomegranate
Concepts
"The mental representation of a class or individual"
Prototype
A "typical" member of the category
What is a typical member of a category?
A "typical" prototype is based on an average of members of a category that are commonly experienced

A depictive representation
The propositional approach may use any of the following EXCEPT 1) an equation 2) a statement 3) abstract symbols 4) a spatial layout
A spatial layout
According to Collins and Quillian's semantic network model, it should take longest to verify which statement below? 1) A turtle is an animal 2) turtles are turtles 3) a turtle is an amphibian 4) a turtle is related to fish

Definitional
How well do good and poor examples of a category compare to other items within the category?
Good examples of the category like sofa and chair when on the category of furniture, have a lot of similar characteristics. When they have a lot of overlap like these, family resemblance of these items is high

Imagery and perception may share the same mechanisms
Participants were asked to imagine different things while laying in the fMRI scanner. Which is LEAST likely to strongly activate the visual cortex? 1) imagine a tic-tac-toe game from start to finish 2) imagine the meaning of the word "politics" 3) imagine your car from far away and then how it looks as you walk closer to it 4) imagine a typical unsharpened pencil. Approximate it's length in inches
Imagine the meaning of the word "politics"
Categories
Includes all possible examples of a particular concept
Conceptual Knowledge
Knowledge that enables us to recognize objects and events and to make interferences about their properties
Imagine that a young child is just learning about the category "dog". Thus far, she has experienced only two dogs, one a poodle and the other a German shepherd. On her third encounter with a dog, she will be most likely to correctly categorize the animal as a dog if that animal.
Looks like an "average" of German shepherd and a poodle
Priming
Occurs when presentation of one stimulus facilitates the response to another stimulus that usually follows closely in time
Sentence verification technique
Procedure that determines how rapidly people can answer questions about an objects category
Categorization
Process by which things are places into categories
What type of members in a category are more affected by priming?
Prototypical
According to the sensory-functional hypothesis, our ability to differentiate living things and artifacts depends on a conceptual knowledge system that distinguishes _________ from _________ .
Sensory attributes; function
When asked to list types of birds, which would be listed first? Sparrow or penguin? And why?
Sparrow, because prototypical objects are typically named first
Low Typicality
The category member does not closely resemble a typical member of the category
What are family resemblances?
The idea that things in a particular category resemble one another in a number of ways. Allows for variation within a category.
We know examples of a common type of bird, like a sparrow. However, Penguins and Owls are also birds. What is a variation like this within a category called?
Typicality
