Stuttering defined Fluency: Starkweather (1986) defined stuttering along four parameters. 1. continuity 2. rate 3. rhythm 4. effort
Disfluency defined • Core behaviors • Secondary behaviors • Feelings and attitudes
Core behaviors • Repetitions • Whole word repetitions (WWR) • Part word repetitions (PWR) • Phrase repetitions
Core behaviors • Prolongations • Vowel prolongations • Consonant prolongations
Core behaviors • Blocks • Broken words • abnormal pauses within words, usually between syllables • tend to last less than 5 seconds • Tense pauses • abnormally long pauses between words, sound caused by tension in the larynx is evident • tend to last less than 5 seconds
Secondary behaviors • Escape behaviors • Physical concommitants • Avoidance behaviors • Starters • Circumlocutions • Situation avoidances • Word/sound avoidances
Feelings and attitudes • Progresses from indifferent and unaware to fear, embarrassment and shame
Bloodstein’s 4 phases of onset and development • Phase 1: • Episodic nature, especially when excited • Repetitions are most common core behavior • No secondary behaviors • No negative feelings/attitudes • 2-6 years
Bloodstein Phase 2 • Stuttering is predictable • Stuttering is consistent • Escape behaviors emerge • Child views self as stutterer and views speaking as difficult • Elementary school age
Bloodstein Phase 3 • Most common core behavior is prolongations • Child uses circumlocutions and substitution avoidances as well as escape behaviors • Embarrassment and shame • 8 years to adulthood
Bloodstein Phase 4 • Most common cores are prolongations and blocks • Avoids words and situations • Fears speaking in many situations • 8 - adulthood
What causes it? • Theories of organic base • Muscles of tongue (ivory forks) • Cerebral dominance theory • Theories of learning • Diagnosogenic theory (W. Johnson) • Operant conditioning • Psychological theories • Freudian-based theories • Current theories • Covert repair theory – reaction to flawed phonetic plan • Demands and capacities model – environmental demands exceed the child’s physical and language abilities
