Question

Quizplus · Accepted Answer

The differential threshold of visual perception refers to the minimum difference between two stimuli that can be detected by a person. In this scenario, consumers noticed the change in the size of the candy bars because the size difference crossed their differential threshold, making it perceptually noticeable. Option A is incorrect because the consumers are not habituated to the new candy bars. Option B is incorrect because preattentive processing is an automatic process that occurs before our attention is directed towards a stimulus. Option C is incorrect because if the difference in the level of stimulus intensity is below their absolute threshold, the consumers would not be able to perceive the change. Option E is incorrect because the just noticeable difference (JND) is the smallest change in a stimulus that can be detected by a person, and in this scenario, the size difference was large enough to be noticed.
