Document Summary

Normal fluency & disfluency: fluency, speech is effortless in nature, easy, rapid, rhythmical, even-flowing, disfluency, marked by: Interjections: word or phrases repetitions, pauses, revisions. Unusually high frequency or durations of: repetitions, prolongations, blocks. Excessive mental and physical effort to resume talking: shift focus to stuttering and lose train of thought. Primary core stuttering behaviors: single-syllable word repetitions, (cid:862)i sa(cid:449), sa(cid:449), sa(cid:449), the (cid:272)at(cid:863, part word repetitions, (cid:455)lla(cid:271)les (cid:894)(cid:449)ith or (cid:449)ithout s(cid:272)h(cid:449)a (cid:448)o(cid:449)el(cid:895)(cid:863)la-ladder(cid:863) Interjections (uh/um: pho(cid:374)e(cid:373)es (cid:862)(cid:271)ase(cid:271),(cid:271),(cid:271),(cid:271)all(cid:863, prolongations, (cid:862)(cid:448)(cid:448)(cid:448)(cid:448)(cid:448)(cid:448)(cid:448)(cid:448)a(cid:374)(cid:863, blocks, ile(cid:374)t prolo(cid:374)gatio(cid:374)s, get stu(cid:272)k (cid:862)the----(cid:272)at (cid:373)o(cid:448)ed(cid:863) Stuttering occurrence: ratio of male stutters to female is 3:1, prevalence for school-aged children (3-17yrs): 1, higher for younger children, overall prevalence: 5, at least 50% of children who stutter improve without intervention. Individual variability: typical duration ~ 3 seconds on average, but can be longer, peaks and valleys of fluency leads to frustration, stuttering can be unpredictable, pressure to be fluent greater dysfluencies, may be fluent when:
