Neophobia

Neophobia is the fear of anything new, especially a persistent and abnormal fear. In its milder form, it can manifest as the unwillingness to try new things or break from routine. In the context of children the term is generally used to indicate a tendency to reject unknown or novel foods. Food neophobia, as it may be referred to, is an important concern in pediatric psychology. In biomedical research, neophobia is often associated with the study of taste.
