To Test Attention, Learning, and Memory in Pigeons, Researchers Use

Multiple Choice

To test attention, learning, and memory in pigeons, researchers use the following protocol. Subjects are trained with compound stimuli (/// on a red key, + on a green key, § on a blue key, and ≡ on an orange key) ; the /// red and § blue keys are rewarded, and the + green and ≡ orange keys are not.

The subjects' task is to respond to the rewarded key colors and not respond to nonrewarded key colors. Researchers measure reaction times and response error rates to determine if the symbol cue helped subjects respond more quickly and accurately. This task is referred to as a _______ task.

A) divided attention
B) delayed matching-to-sample

D) priming
