A cat is trained to fetch a piece of balled paper. The cat has learned that the sound of the paper being crumpled means that the game is on. The game being on tells the cat that the paper is about to fly. Seeing the flying paper means that it is time for the hunt. Grabbing the paper lets the cat know that a treat is waiting. This cat must have learned


A) paired associates.
B) a serial pattern.
C) stimulus-response associations.
D) serial representations.

A trial begins with presentation of a discriminative stimulus. If the stimulus is a light, a food pellet reinforcer will be set up after 20 seconds and can be earned with a lever press. If the stimulus is a tone, a food pellet reinforcer will be set up after 40 seconds and can be earned with a lever press. Test trials involve recording the subject's responses over 80 non-reinforced seconds. This type of experiment is investigating an organism's ability to


A) form concepts.
B) produce durations.
C) estimate durations.
D) chunk information.

After learning to press five keys, "A" through "E," in alphabetical order, monkeys were given tests in which subsets of two keys were presented. A comparison of the latencies to press the second key revealed that as the number of letters missing between the two test keys increased, (BD) versus (BE) for example, the latency to press the second key _____, suggesting that the monkeys were subject to the symbolic distance effect.


A) remained the same
B) increased
C) decreased
D) increased if the first key was "A" or "B," and decreased if the first key was "C" or "D" ("E" could not be the first key)
