Stuttering is a complex and multifaceted disorder. Several theoretical accounts of both the onset and stuttering moments point to a complex interaction of multiple factors/contributors as their origin. One of the important contributors to the emergence of stuttering and its developmental path is temperament/emotion. The purpose of this article is to provide basic description of temperament and emotion, and review empirical evidence regarding the relationships between temperamental/emotional factors and childhood stuttering. The possible implications for clinical assessment and treatment in children who stutter are discussed.
