Question

Jason, a personal care product manufacturer, incorporates customers' suggestions in designing a new line of safety razors for men. The new product is launched with thinner, finer blades. However, when the new razors reach the market, customers fail to notice any improvement in them. In the given scenario, the customers' reactions indicate that the new razor design has failed to register the _____.

A. mere exposure effect
B. mere association effect
C. just meaningful difference
D. just noticeable difference

Answer 1

The answer is option (D) just noticeable difference.

Step-by-step explanation:

Just noticeable difference (JND) is a term which describes the minimum difference or amount of difference that can be sensed, detectable or noticeable.

Although Jason's razors were made thinner and finer than used to be, they didn't grab the attention of users because the changes made on the razor were below the minimum difference or amount of difference that could be noticeable by users of the razors.
