Quizplus · Accepted Answer

Infants have limited communication abilities, but their looking behavior can be used as a measure of their preferences and perceptual discrimination abilities. When they look longer at one of two stimuli presented side-by-side, researchers infer that the infant can discriminate between the stimuli and prefers the stimulus they are looking at for a longer period of time. Therefore, the correct answer is D - the infant can discriminate between the stimuli and prefers that stimulus.
