Stuttering is a
complex condition involving much more than the disfluencies
that non-stutterers notice. The bulk of the stuttering
phenomenon is hidden. Stuttering affects the whole person.
Stuttering includes destructive feelings, perceptions and
emotions such as shame, embarrassment, guilt, low
self-esteem, frustration and fear of particular speaking
situations. The stuttering phenomenon also encompasses
unusual behaviors such as irregular breathing patterns, eye
contact avoidance and word substitutions.
