Suppose an ice cream manufacturer commissioned Dr. Mandisa, a flavor chemist, to develop an enhancement to their product line. The company wishes to improve Luscious Lemon Vanilla Vanity. What psychophysical concepts might Dr. Mandisa employ??
What will be an ideal response?
ANSWER:
?Dr. Mandisa could choose to improve the lemon or the vanilla flavor. By examining the difference threshold, she could establish the minimum change needed so that either the lemon or the vanilla could be detected 50% of the time. Using Weber’s law, the additional amounts of vanilla and lemon needed to produce a just noticeable difference (jnd) could be calculated. With this knowledge about the flavors, Dr. Mandisa could then provide company executives with data needed to arrive for possible production decisions.
