Recording Facial Expressions to Assess Taste in Children and Teenagers

A video recording of a subject's facial expressions while tasting a sweet, bitter, and neutral flavored liquid will be analyzed using Noldus Facereader 7 software.

A voice recording will be made for the duration of the tasting period.

A 5-point facial hedonic scale will be given to the participant to complete prior to the administration of any test substances and about 5, 10, and 30 minutes after the administration of each test substance.

Participants will be asked a few questions about each test agent after tastings.
