Question

Quizplus · Accepted Answer

Observing infants' facial expressions or head movements to see whether they respond differently to bitter and salty tastes would be the best choice. Infants may not be able to verbally communicate their taste preferences, but their nonverbal reactions can provide insight into whether they can distinguish between the two tastes. Repeatedly presenting one taste may not be effective if the infant becomes habituated to it, and using older infants or toddlers who can verbally communicate may not be appropriate for this particular question. Asking adults about their own experiences with bitter and salty tastes is not relevant to whether infants can distinguish between the two tastes.
