Purpose: The present study investigated phonological encoding skills in children who stutter (CWS) and those who do not (CNS). Participants were 9 CWS (M=11.8 years, SD=1.5) and 9 age and sex matched CNS (M=11.8 years, SD=1.5). Method: Participants monitored target phonemes located at syllable onsets and offsets of bisyllabic words. Performance in…

Purpose: This study adds to the Lidcombe Program evidence base by comparing individual and group treatment of preschoolers who stutter. Method: A randomized controlled trial of 54 preschoolers was designed to establish whether group delivery outcomes were not inferior to the individual model. The group arm used a rolling group model, in which a…

Purpose: This study examined the effect of speech rate on phonated intervals (PIs), in order to test whether a reduction in the frequency of short PIs is an important part of the fluency-inducing mechanism of chorus reading. The influence of speech rate on stuttering frequency, speaker-judged speech effort, and listener-judged naturalness was also…

Background: Metronome-paced speech results in the elimination, or substantial reduction, of stuttering moments. The cause of fluency during this fluency-inducing condition is unknown. Several investigations have reported changes in speech pattern characteristics from a control condition to a metronome-paced speech condition, but failure to control…

Background: Overt stuttering is inhibited by approximately 80% when people who stutter read aloud as they hear an altered form of their speech feedback to them. However, levels of stuttering inhibition vary from 60% to 100% depending on speaking situation and signal presentation. For example, binaural presentations of delayed auditory feedback…

Actuality of studying of an issue on specific manifestations of a monologue speech type in bilingual schoolchildren with stutter has been stipulated by the necessity of elaboration of a constituent concept on central mechanisms underlying this kind of communication disorder, on the nature of disturbances of speech formation mechanisms in the…

Phonetically governed changes in the fundamental frequency (F[subscript 0]) of vowels that immediately precede and follow voiceless stop plosives have been found to follow consistent patterns in adults and children as young as four years of age. In the present study, F[subscript 0] onset and offset patterns in 14 children who stutter (CWS) and 14…

While stuttering is known to be characterized by anomalous brain activations during speech, very little data is available describing brain activations during stuttering. To our knowledge there are no reports describing brain activations that precede blocking. In this case report we present magnetoencephalographic data from a person who stutters…

Nonword repetition and phoneme elision represent the combined influence of several speech and language processes. In the present study we investigated nonword repetition and phoneme elision performance in school-age children who stutter (CWS) and children who do not stutter (CNS). Participants were 14 CWS (mean = 11.7 years, SD = 2.1 years) and…

Purpose: The "Public Opinion Survey of Human Attributes-Stuttering" ("POSHA-S") was developed to make available worldwide a standard measure of public attitudes toward stuttering that is practical, reliable, valid, and translatable. Mean data from past field studies as comparisons for interpretation of "POSHA-S" results are reported. Method: Means…

The purpose of this investigation was to provide normative and comparative data for the BigCAT, the adult form of the Communication Attitude Test, a sub-test of the Behavior Assessment Battery. The BigCAT, a 35-item self-report test of speech-associated attitude was administered to 96 adults who stutter (PWS) and 216 adults who do not (PWNS). The…

Background: It is frequently observed that listeners demonstrate gaze aversion to stuttering. This response may have profound social/communicative implications for both fluent and stuttering individuals. However, there is a lack of empirical examination of listeners' eye gaze responses to stuttering, and it is unclear whether cultural background…

Purpose: The study investigated the extent to which differences existed between public attitudes of males versus females. Method: One hundred adults, 50 males and 50 females, were chosen at random from each of 50 study samples comprising a total of 3371 respondents in a database archive who had completed the "Public Opinion Survey of Human…

The present study compared the ability of 12 people who stutter (PWS) and 12 people who do not stutter (PNS) to consolidate a novel sequential speech task. Participants practiced 100 repetitions of a single, monosyllabic, nonsense word sequence during an initial practice session and returned 24-h later to perform an additional 50 repetitions.…

The BigCAT and the Erickson S-24, self-report measures of communication attitude, were administered in a randomly determined order to 72 adults who stuttered (PWS) and 72 who did not (PWNS). The two groups of participants differed from each other to a statistically significant extent on both of these measures of speech-associated attitude,…
