Question

Quizplus · Accepted Answer

In a similarity-based perceptual map, objects are grouped together based on their visual or functional similarities. However, in a preference-based perceptual map, objects are grouped together based on the subjective preferences of consumers, which may not necessarily be solely based on visual or functional similarities. Therefore, two objects could be perceived as very different in a similarity-based perceptual map, but could be grouped together as similar in a preference-based perceptual map because consumers have similar preferences towards them.
