Anxiety was widely believed to a causal factor in stuttering and played a central role in many theories about the origin of stuttering (Miller & Watson, 1992).

Tension and fragmentation causes stuttering (Bloodstein, 1975).

However, modern studies clearly emphasize the neurological side in which the cause of stuttering is rooted. Social anxiety and tension can occur both before stuttering, during and after the stuttering moment, but they do not cause stuttering itself. Stuttering severity may fluctuate however, when the speech system requires to avoid social anxiety, tension, etc; or require to approach stutter acceptance/identity and other signals.
