Perceived nasality in the speech of the deaf.

Listener ratings of nasality were obtained from samples of deaf and normal speech presented in the backward play mode. In order to investigate the influence of rhythmic patterning on the perception of nasality, seven of the normal speakers also produced the samples in a word-by-word fashion. Statistically significant differences in mean ratings of nasality were found between the experimental and control groups and between the reduced-tempo and normal-tempo groups. In general, deaf speakers are perceived as more nasal than normal speakers. Furthermore, normal speakers are perceived as more nasal when speaking at a reduced tempo than when speaking at a normal tempo. Much of the perceived nasality in the speech of the deaf may be a natural consequence of reduced speaking tempo, and therapeutic techniques designed to increase speaking tempo may produce a concomitant reduction in perceived nasality.

The speech production and spoken language of the deaf.

The distinction was made between speech production and spoken language in analysing the oral output of those with hearing impairment. A brief review of studies in both areas was undertaken, including the report of a new electronic visual monitoring device, the glossal transducer. It was postulated that the deaf utilise a unique visual-to-motor conversion within the brain when speaking and monitor consciously by tactile-kinæsthetic control. The more recent studies relate to the syntactical features of the speech of the deaf. These show that deafness creates telegraphic speech with reduced sentence length and omissions of essential words such as functors. The speech of the deaf seems to contain mostly nouns and verbs, with a limited number of words used to expand verb forms.

Differential diagnosis of oligophrenia.

IN THE diagnosis of mental deficiency, dependent as it is not only on medical and psychological criteria but also on social standards, the defect must be distinguished from a considerable number of other conditions. These may conveniently be classified under the headings of intellectual defects of a less ominous nature, specific defects of a visual, auditory, or speech nature, and behavior defects in which the aberrant conduct is likely to be confused with mental defect. The following arrangement may serve to indicate the extent of these conditions: I. Intellectual defects Educational defectiveness Dullness Backwardness Specific defects Visual defects Blindness Visual cerebral injury Congenital word blindness Auditory defects Deaf-mutism High-tone deafness Congenital word deafness Speech defects Mutism Delayed development of speech Congenital motor aphasia Behavior defects Delinquency Maladjustment Adolescent instability
