In a study, participants listened to the following tape recording: Rumor had it that, for years, the government building had been plagued with problems. The man was not surprised when he found several spiders, roaches, and other bugs in the corner of the room. As participants heard the word "bugs," they completed a lexical decision task to a test stimulus flashed on a screen. Results showed that the participants responded most slowly to the test stimulus

SKY.

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?

humans are genetically programmed to acquire and use language.

Imagine that a young child is just learning about the category "dog." Thus far, she has expe-rienced 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

is a dog that does not bark.

Collins and Loftus modified the original semantic network theory of Collins and Quillian to satisfy some of the criticisms of the original model. However, their revised model was not im-mune to criticism. One criticism of Collins and Loftus' semantic network theory is that it

is of little explanatory value because it can explain just about any result.

According to the typicality effect,

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

Lilo can't wait for school to start. This year is the first time she gets to take a foreign language class, and she is taking Japanese. Dr. Nabuto is a professor interested in studying how people learn additional languages later in life, and he is including Lilo's class in his research. Dr. Nabuto is most likely studying

language acquisition.

Ron is an avid reader. He has a large vocabulary because every time he comes across a word he doesn't know, he looks it up in the dictionary. Ron encounters "wanderlust" in a novel, reaches for the dictionary, and finds out this word means "desire to travel." The process of looking up unfamiliar words increases Ron's

lexicon.

Olin and Bob are neighbors. Olin 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 Olin's standard probably involves

more exemplars than Bob's.
