A reaction to the review of replicated findings concerning stuttering cites disagreement with the definition of stuttering used and notes implications for findings on treatment, clinical effects, recovery, stutterer-nonstutterer differences, and theory. (CL)

This paper argues against definitions of stuttering which imply that all within-word disfluencies are stuttering and no between-word disfluencies are stuttering. The paper calls for a definition of stuttering that is not contradicted by available empirical information or clinical experience and is logically consistent. (JDD)

This letter to the editor comments on a 1998 article by J. S. Yaruss which proposed that classification of stuttering be adopted to foster improvement in basic understanding. The article is critiqued as failing to recognize the two major components of a stuttering event and for the author's definitions of impairment and disability as applied to…

This rebuttal of a response to the author's original article on improved classification of stuttering in the context of disability, impairment, and handicap, stresses that the model originally proposed carefully distinguishes the two major aspects of stuttering and offers definitions of impairment, disability, and handicap consistent with the…

This commentary on EC 232 373 and EC 232 374 suggests that a theory that depends on categorizing events as either stuttering or nonstuttering must fail. It evaluates the merit of the voluntary/involuntary distinction in loss of speech production control, defends research on the nature of stuttering, and proposes additional research and theory.…

The paper argues that listeners are unable to judge unit-by-unit occurrences of stuttering acceptably. Reasons for this state of affairs and its implications for therapy, theory, and research are analyzed. An alternative speech production definition with its implications is proposed, and a diagnostic method of validating authentic stuttering is…

The commentary to EC 232 373 and EC 232 374 discusses whether stuttering is really what the listener perceives, the stutterer senses, or the dictionary states. It concludes that stuttering can probably be defined in appropriate contexts as any or all of these three things. (JDD)

This commentary to EC 232 373 and EC 232 374 challenges the use of a speaker-based definition of stuttering and argues that use of the definition may only relocate the judgment reliability problem and raise as many validity problems as a listener-based definition of stuttering does. (JDD)

The characteristic features of psychogenic stuttering of adult onset are reviewed, and four cases of this disorder are presented. Psychogenic stuttering of adult onset is classified as a conversion reaction, and tentative criteria for this diagnosis are proposed. (Author/JDD)

A response is presented to commentaries (EC 232 375-377) on two papers (EC 232 373 and EC 232 374), focusing on research methodology on stuttering, the impact of improving intrajudge and interjudge agreement, the importance of studying stuttering as a private experience rather than an acoustical event, and speakers' experience of loss of control…
