Which of the following terms is most closely associated with semantic networks?

Cognitive economy

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.

___________is a "typical" member of a category.

A prototype

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 a property of the connectionist approach?

Before any learning has occurred in the network, the weights in the network all equal zero.

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

Which approach to categorization can more easily take into account atypical cases such as flightless birds?

Exemplar

___________ are actual members of a category that a person has encountered in the past.

Exemplars

Which of the following is NOT associated with the semantic network model?

Family resemblance

Which of the following represents a basic level item?

Guitar

Which of the following is NOT one of the types of units found within a parallel distributed processing model?

Working units

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

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

Which of the following would be in a basic level category?

Truck

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.

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

According to Rosch, the ___________ level of categories reflects people's everyday experience.

basic

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.

Learning in the connectionist network is represented by adjustments to network

connection weights.

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 definitional approach to categorization

doesn't work well for most natural objects like birds, trees, and plants.

If you say that "a Labrador retriever is my idea of a typical dog," you would be using the ___________ approach to categorization.

exemplar

Research suggests that the ___________ approach to categorization works best for small categories (e.g., U.S. presidents).

exemplar

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.

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.

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

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

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

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

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.

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.

Collins and Quillian's semantic network model predicts that the reaction time to verify "a canary is a bird" is ___________ the reaction time to verify "an ostrich is a bird."

the same as

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

An advantage of the exemplar approach over the prototype approach is that the exemplar approach provides a better explanation of the ___________ effect.

typicality

Priming occurs when presentation of one stimulus

facilitates the response to another stimulus that usually follows closely in time.
