Preliminary findings from a longitudinal study of 32 preschool children who stutter and 32 nonstuttering controls reveal 4 subgroups: (1) persistent stuttering; (2) late recovery; (3) early recovery; and (4) control. Comparative data for the groups regarding frequency of disfluency, acoustic features, phonologic skills, language development,…

A study of children who stutter (n=12), who have recovered early from stuttering (n=12), and who recovered later from stuttering (n=12) compared the phonological characteristics of the three groups with a control group. Results indicated that poor phonological ability in the early stage of stuttering appeared to be a contributing factor to the…

A study investigated frequency change and duration of the second formant (F2) transition in speech samples recorded close to stuttering onset in 10 preschoolers who stutter, 10 who recovered from stuttering, and 10 controls. Near stuttering onset, children whose stuttering persisted demonstrated significantly smaller frequency change than the…

A four-year study of 84 preschool children (25 to 59 months) who stutter found a continuous diminution in the frequency and severity of stuttering over time as many children progressed toward recovery. Findings indicate a 74% overall recovery rate for stuttering and a 26% persistency rate. (CR)

A study compared the phonological abilities of 22 preschool children whose stuttering persisted and 62 who recovered. Those whose stuttering persisted had poorer mean scores on a number of phonological characteristics, including mean percentage of error, relative levels of severity of phonological impairments, and error on specific phonological…

A study compared the expressive language abilities of 22 preschool children whose stuttering persisted and 62 who recovered over a four-year period. Findings revealed similarity in the abilities of children whose stuttering persisted as opposed to abated at all ages. All stutterers displayed abilities near or above developmental expectations. (CR)
