Identification and discrimination of speech sounds in monosyllabic meaningful words and nonsense words by children.

297 children aged 9-14 with normal hearing and intelligence level were examined by speech audiometry. Ten lists with monosyllabic meaningful and nonsense words were used. All the lists were phonemically and structurally balanced in the same way and were applied with an intensity level varying between 26 dB and 61 dB. The identification and discrimination scores for Polish speech sounds were calculated from written-response sheets. The identification scores were generally significantly lower for nonsense words, and up to a certain extent, increased with age. An examination of the discrimination scores showed that confusions were related to the distinctive features of the phonemes. The results represent the first stage of a project on speech sound identification in children and may have practical implications for the rehabilitation of children with hearing loss.

Speech audiometry for children and subjective probability of Polish words.

Word lists used for speech audiometry should fulfill a number of conditions in order that the results of hearing tests be unambiguous and directly interpretable not only in terms of possible hearing loss but also in terms of the neurolinguistic decoding process. In order to construct a proper word list, it was decided to attempt to estimate the subjective probability of word occurrence in schoolchildren. Nine different lists of over 300 words each were prepared, containing words of all assumed degrees of familiarity. In the preliminary stage, the lists were presented to 600 children in primary and secondary schools. The children were asked to mark each word with a number indicating their relative familiarity with the word. The answers were examined for homogeneity.

[Fatigability of stapedius muscle in myasthenia].

The fatiguability of m. stupedius was studied in 20 patients with myasthenia and 16 controls determining the reflex of this muscle by means of electroacoustic bridge. In half of the patients group the fatiguability of stapedius muscle was increased and in some cases the reflex threshold of the muscle was raised. The authors suggest continuation of these investigations especially for determination of the clinical importance of these observations.
