Background: Speech-language pathologists often multitask in order to be efficient with their commonly large caseloads. In stuttering assessment, multitasking often involves collecting multiple measures simultaneously. Aims: The present study sought to determine reliability when collecting multiple measures simultaneously versus individually.…

The present study examined listeners' identification and rating of words in passages as stuttered when the duration and frequency of occurrence of sound prolongations were manipulated. Thirty-six participants listened to a 219-word passage containing voiceless fricatives digitally increased from their normal durations to 200, 300, and 420 ms.…

Purpose: To determine whether young children who stutter have a basic motor timing and/or a coordination deficit. Method: Between-hands coordination and variability of rhythmic motor timing were assessed in 17 children who stutter (4-6 years of age) and 13 age-matched controls. Children clapped in rhythm with a metronome with a 600-ms interbeat…

Purpose: This study introduces a series of systematic investigations intended to clarify the parameters of the fluency-inducing conditions (FICs) in stuttering. Method: Participants included 11 adults, aged 20-63 years, with typical speech-production skills. A repeated measures design was used to examine the relationships between several speech…

Purpose: The effect of frequency altered feedback (FAF) on stuttering type (i.e., prolongation, repetition, or silent block) and stuttering duration (i.e., average duration of stuttering event and total stuttering time) was examined. Method: Retrospective analyses of previously collected data from 12 adult persons who stutter who participated in…

Coordinated interpersonal timing (CIT) is a measure of "conversational congruence," or "attunement," and refers to the degree to which the temporal aspects of the vocal behaviors of co-conversationalists are correlated over the course of a conversation [Jasnow, M., & Feldstein, S. (1986). "Adult-like temporal characteristics of mother-infant vocal…
