When examining the CR as a measure of learning in the eyeblink reflex, researchers most commonly use _________.
A) intensity of a response
B) latency of a response
C) the presence vs. nonpresence of a UR
D) percentage of trials in which a CR occurs

Question

Quizplus · Accepted Answer

The most common measure of learning in the eyeblink reflex is the percentage of trials in which a CR (conditioned response) occurs. This measure is used because it allows researchers to determine the extent to which learning has occurred by comparing the number of trials in which the CR is present to the number in which it is not. Other measures, such as the intensity of a response or the latency of a response, may provide useful information, but they are typically not used as frequently as the percentage of trials with a CR. The presence vs. nonpresence of a UR (unconditioned response) is also important in evaluating learning in the eyeblink reflex, but it is not typically used as the primary measure of learning.
