If a system has the property of graceful degradation, this means that it is either functioning at 100 percent, or it is not functioning at all. it can be set to operate at "low efficiency" or "high efficiency" depending on the demand of the current task. damage to the system doesn't completely disrupt its operation. it loses information at a very slow rate.

damage to the system doesn't completely disrupt its operation.

An advantage of the exemplar approach over the prototype approach is that the exemplar approach provides a better explanation of the ________ effect. resemblance priming reaction-time typicality

typicality

According to the ________ approach, there are certain types of concepts that have specific neural circuits in the brain. sensory-functional semantic category neuronal limitation multiple-factor

semantic

The semantic network model predicts that the time it takes for a person to retrieve information about a concept should be determined by the amount of information contained in each concept. the distance that must be traveled through the network. the typicality of the information contained in each concept. the representativeness of the information contained in each concept.

the distance that must be traveled through the network.

Which of the following statements is NOT cited in your text as a reason why categories are useful? Categories serve as a valuable tool for making inferences about things that belong to other categories. Categories provide definitions of groups of related objects. Categories help us understand behaviors that we might otherwise find baffling. Categories have been called "pointers to knowledge" because once you know an object's category, you know a lot of general things about it.

Categories provide definitions of groups of related objects.

When a participant is asked to list examples of the category vegetables, it is most likely that a carrot would be named before eggplant. an eggplant would be named before carrot. a carrot and eggplant would have an equal likelihood of being named first. the order of examples is completely random, varying from participant to participant.

a carrot would be named before eggplant.

Learning takes place in a connectionist network through a process of _____ in which an error signal is transmitted starting from the property units. spreading activation graceful degradation error verification back propagation

back propagation

According to Rosch, the ____ level of categories is the psychologically "privileged" level of category that reflects people's everyday experience. prototypical superordinate basic subordinate

basic

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. obstruction overlapping crowding convergence

crowding

One beneficial property of connectionist networks is graceful degradation, which refers to the property that learning can be generalized between similar concepts to facilitate future learning. these networks learn by a process that is analogous to the way a child learns about the world by making mistakes and being corrected. damage to the system does not completely disrupt its operation. learning a new concept does not interfere with remembering a previously learned concept.

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. family resemblance prototype definitional

definitional

Which of the following is not one of the types of units found within a parallel distributed processing model? Hidden units Output units Input units Working units

working

Which of the following is NOT a property of the connectionist approach? The connectionist model is rather complex, and involves components like units, links, and connection weights. Connectionist networks can explain generalization of learning. The operation of connectionist networks is not totally disrupted by damage. Before any learning has occurred in the network, the weights in the network all equal zero.

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

The definitional approach to categorization is not well suited for geometrical objects but works for familiar everyday objects. was proposed to replace the prototype approach. sets definite criteria called family resemblances that all category members must have. doesn't work well for most natural objects like birds, trees, and plants.

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

Imagine that a young child is just learning about the category "dog." Thus far, she has experienced only two dogs, one a small poodle and the other a large 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 matches an exemplar of one of the dogs she has experienced. is a dog that does not bark. matches the size of the poodle but is of a different breed. is similar to an "average" for the dogs she has encountered.

is a dog that does not bark

According to the typicality effect, objects in a category have a family resemblance to one another. we remember typical objects better than non-typical objects. objects that are not typical stand out and so are more easily remembered. items that are high in prototypicality are judged more rapidly as being in a group.

items that are high in prototypicality are judged more rapidly as being in a group

In the semantic network model, a specific category or concept is represented at a output unit. node. input unit. link.

If we were conducting an experiment on the effect knowledge has on categorization, we might compare the results of expert and non-expert groups. Suppose we compare horticulturalists to people with little knowledge about plants. If we asked the groups to name, as specifically as possible, five different plants seen around campus, we would predict that the expert group would primarily label plants on the _____ level, while the non-expert group would primarily label plants on the _____ level. subordinate; basic superordinate; basic superordinate; subordinate basic; subordinate

subordinate; basic

People playing the parlor game "20 Questions" often use hierarchical organization strategies. One player asks up to 20 yes/no questions to determine the identity of an object another player has selected. The player's questions usually start as general and get more specific as the player approaches a likely guess. Initial questions asked by a player are often one of three questions: "Is it an animal?" "Is it a vegetable?" and "Is it a mineral?" Each of these three questions describes which level of categorization? Superordinate Basic Typical Subordinate

superordinate

Priming occurs when presentation of one stimulus relates to a prototype in a way that is unrelated to associated exemplars. acts as a cue that tells the participant when his or her response was correct. facilitates the response to another stimulus that usually follows closely in time. disrupts the processing of another stimulus

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