Stuttering is a speech disorder that affects the natural forward flow of speech. The speech of a person who stutters is characterized by repetitions of a sound or syllable. The onset is most likely to occur between the ages of two and five. Many psychological, physiological, environmental, and linguistic factors influence the occurrence of stuttering. This paper describes two currently popular theories which attempt to explain language delay as an etiological factor related to stuttering, "Neuropsycholinguistic Theory" and "Demands and Capacities Model." Following discussion of these theories, a series of research articles related to these theories are discussed.
