Chapter 9 Cognitive psych
Collins and Quillian explained the results of priming experiments by introducing the concept of ___________ into their network model.
spreading activation
Items high on prototypicality have ___________ family resemblances.
strong
A task for determining how prototypical an object is would be
a task where participants rate the extent to which each member represents the category title.
According to Collins and Quillian's semantic network model, it should take longest to verify which statement below?
a turtle is an animal
Which of the following is NOT one of the types of units found within a parallel distributed processing model?
working units
___________is a "typical" member of a category.
A prototype
It may be difficult for young Matthew, who is only 4 years of age, to understand the difference between the iPad that his mother uses, the Kindle that his brother uses, and the Galaxy tablet that his sister uses. After all, all of them are tablets, have touch screens, are electronic technology, and run "apps" that include games and educational programs. These similarities remind us of the concept of ___________, which refers to the fact that animals tend to share many different properties.
crowding
In the multiple-factor approach, the fact that people exhibit physical attributes, actions, and emotions is known as ________.
crowding (multiple)
One beneficial property of connectionist networks is graceful degradation, which refers to the property that
damage to the system does not completely disrupt its operation.
Not all of the members of everyday categories have the same features. Most fish have gills, fins, and scales. Sharks lack the feature of scales, yet they are still categorized as fish. This poses a problem for the ___________ approach to categorization.
definitional
If you say that "a Labrador retriever is my idea of a typical dog," you would be using the ___________ approach to categorization.
examplar (typical)
Spreading activation
primes associated concepts.
Rosch found that participants respond more rapidly in a same-different task when presented with "good" examples of colors such as "red" and "green" than when they are presented with "poor" examples such as "pink" and "light green." The result of this experiment was interpreted as supporting the ___________ approach to categorization.
prototype
In a lexical decision task, participants have to decide whether
a presented stimulus is a word
An advantage of the exemplar approach over the prototype approach is that the exemplar approach provides a better explanation of the ___________ effect.
typicality
In the semantic network model, a specific category or concept is represented at a
node
Which of the following reaction time data sets illustrates the typicality effect for the bird category, given the following three trials? (NOTE: Read data sets as RTs for Trial 1: Trial 2: Trial 3) Trial 1: An owl is a bird. Trial 2: A penguin is a bird. Trial 3: A sparrow is a bird.
583: 653: 518 ms
According to the hub and spoke model, which area of the brain serves as the hub?
Anterior temporal lobe
Which of the following is a connectionist model proposing that concepts are represented by activity that is spread across a network?
Parallel distributed processing theory
One criticism of the embodied approach is that it doesn't explain how humans can recognize ________.
abstractions
Learning takes place in a connectionist network through a process of ___________ in which an error signal is transmitted starting from the property units.
back propagation
Which of the choices best represents cognitive economy in the following sentence? The property _______is stored at the _______node.
can fly; bird
The prototype approach to categorization states that a standard representation of a category is based on
category members that have been encountered in the past.
Two different definitions of ___________ offered by your book include (a) "the mental representation of a class or individual," and (b) "categories of objects, events, and abstract ideas."
concepts
One of the key properties of the ___________ approach is that a specific concept is represented by activity that is distributed over many units in the network.
connectionist
The process of back propagation is most closely associated with
connectionist networks
The four proposals addressing the representation of concepts in the brain all agree that the information is ________.
distributed
___________ are actual members of a category that a person has encountered in the past.
exemplars
The principle illustrated when most people are able to recognize a variety of examples of chairs even though no one category member may have all of the characteristic properties of "chairs" (e.g., most chairs have four legs but not all do) is
family resemblance.
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 LEAST likely to correctly categorize the animal as a dog if that animal
is a breed of dog that is hairless and teacup-sized.
According to the typicality effect
items that are high in prototypicality are judged more rapidly as being in a group.
Which of the following lies at the foundation of a connectionist network?
learning
Jorge and Bob are neighbors. Jorge loves birds and his father works for the zoo. He has been to a dozen bird sanctuaries, and he and his dad go on bird watching hikes once a month. In contrast, Bob doesn't think much about birds. His only contact with them is in his backyard. It would be correct to say that Jorge's standard probably involves
more exemplars than Bob's.
Which approach to categorization involves forming a standard representation based on an average of category members that a person has encountered in the past?
prototype
According to the ___________ approach, there are certain types of concepts that have specific neural circuits in the brain.
semantic category
The ___________ model includes associations between concepts and the property of spreading activation.
semantic network
According to the sensory-functional hypothesis, our ability to differentiate living things and artifacts depends on a semantic memory system that distinguishes _____ and one that distinguishes _____.
sensory attributes; function
Based on the information your textbook provided about different category types, jumping from ___________ categories results in the largest gain in information.
superordinate level to basic level
According to the connectionist model, which of the following is impacted by connection weight?
synapse activity
The semantic network model predicts that the time it takes for a person to retrieve information about a concept should be determined by
the distance that must be traveled through the network.
Which of the following theories on conceptual representation combines both sensory and motor experiences?
the embodied approach
The connectionist network has learned the correct pattern for a concept when
the error signals are reduced to nearly none and the correct properties are assigned.
Rosch and coworkers conducted an experiment in which participants were shown a category label, like a car or vehicle, and then, after a brief delay, saw a picture. The participants' task was to indicate as rapidly as possible whether the picture was a member of the category. Their results showed
the priming effect was most robust for basic level categories.
Which of the following would be in a basic level category?
truck
For the category "fruit," people give a higher typicality rating to "banana" than to "kiwi." Knowing that, we can also reason that
the word "fruit" will lead to a larger priming effect for banana than for kiwi.
Your text describes cross-cultural studies of categorization with U.S. and Itzaj participants. Given the results of these studies, we know that if asked to name basic level objects for a category, U.S. participants would answer ___________ and Itzaj participants would answer ___________.
tree;oak
Priming occurs when presentation of one stimulus
facilitates the response to another stimulus that usually follows closely in time.
