ABSTRACT
The fluency of people who stutter is affected markedly when auditory feedback is altered, suggesting that stuttering may be associated with hearing. Peripheral hearing problems, however, are no more common in people who stutter than in those who do not. Performance was investigated in a task that involves central auditory processing (backward masking). Children who stuttered had deficits in backward masking (indicated by higher thresholds) compared with a group of fluent control children. The backward-masking thresholds were positively correlated with frequency of stuttering.

Accurate methods for locating specific types of stuttering events are necessary for diagnosis, treatment, and prognosis. A factor that could add variability to assessment of stuttering is noise on recordings. The effects of noise were assessed by adding noise to intervals of speech containing all fluent material, fluent material with a repetition, or fluent material with a prolongation. These intervals allow a unique dysfluency response to be made. A statistical analysis of the occurrence of such intervals in spontaneous speech showed that only a limited number of intervals met these criteria. This demonstrated that selecting intervals at random from spontaneous speech (as in time interval analysis procedure) will infrequently lead to a unique and unambiguous dysfluency specification for the interval. Intervals were selected for testing from the intervals that met the stipulated criteria. These were presented for dysfluency judgment when the position of the stuttering within an interval was varied and with different amounts of added noise (no added noise, 3 dB, and 6 dB of noise relative to mean speech amplitude). Accuracy in detecting stuttering type depended on noise level and the stuttering's position in the interval, both of which also depended on the type of stuttering: Noise level affected detection of repetitions more than prolongations: Repetitions were more difficult to detect when they occurred at the end of an interval whereas prolongations were more difficult to detect when they were at the beginning of an interval. The findings underline the importance of adopting rigorous recording standards when speech is to be employed to make stuttering assessments.

Dr Onslow's brief articles and his lecture tour in the UK generated interested in the UK because the Lidcombe Programme appeared to offer the possibility of a new, simple and effective package for use with young stammering children. This commentary has sought to examine these aspects more objectively by careful consideration of the paper submitted to this Journal and others. It would seem of great importance to reflect on the theoretical issues which have been covered as well as the relative complexity of the Lidcombe Programme compared with the approaches that are in common usage now in specialist centres in the UK. Dr Onslow and his colleagues have given us an opportunity to highlight the importance of working with young stammering children and we would hope that the interest that they have created will inspire colleagues to investigate further training opportunities for working with this very rewarding client group.

The role of parents in the development of the communicative competence of their children has been of growing interest to researchers and practitioners in the field of speech and language therapy. Researchers have attempted to define and test specific hypotheses regarding the nature and degree of the influence of parental interaction styles upon the developing child's pragmatic skills. The literature includes studies regarding normal children and those with speech and language impairments. Practitioners have endeavoured to move towards a firmer framework of partnership with parents which will ultimately be of benefit to children with speech and language impairments and their families.

In a controlled trial of treatment for stammering under stress oxprenolol (40 mg) compared with placebo was assessed in a double-blind manner over two days, six weeks apart, in 31 stammerers before and after speech therapy. The trial design also allowed six weeks of intensive speech therapy, using a slowed-speech and relaxation technique, to be compared with not treatment and assessed single-blind. Oxprenolol produced a significant fall in pulse rate and systolic blood pressure but no overall change in performance either before or after speech therapy. Intensive speech therapy produced a highly significant improvement in the global performance of untrained subjects (p less than 0.001) and a significant reduction in the number (p less than 0.001) and duration (p less than 0.001) of blocks. Maintenance speech therapy tended to produce further improvement in trained subjects. Speech therapy is apparently an effective treatment for stammering, whereas oxprenolol appears to be of no value when given routinely; oxprenolol may be of value, however, in very stressful conditions.
