Performance of children with good and poor articulation on tasks of tongue placement.

This study determined whether children could learn to replicate four positions of lingual-palatal contact with and without topical anesthesia that eliminated touch-pressure sensations. First-grade boys, nine with good articulation skills and nine with poor articulation skills, were used as subjects. Results suggest that individuals are able to learn nonspeech tasks of tongue positioning by relying on muscle spindles or deep receptors within the tongue, or both, or by relying on lingual touch-pressure or other surface receptors within the tongue, or, by a combination of deep and surface receptors of the tongue. Further, tongue positioning need not be dependent on touch-pressure or superficial tactile mechanisms. Children with relatively severe articulation problems performed more poorly on the tasks of precise tongue placement than children with good articulation skills. And finally, children with relatively severe articulation problems may be able to improve their initially poor performance on tongue placement tasks with specific training on those tasks, implying that this group did receive the intraoral sensory feedback necessary to learn the task, but that more experience was needed for the learning to occur.

An assessment of informative-counseling procedures for cleft palate children.

32 children with cleft palate and their mothers were interviewed for the purpose of learning what information they had about cleft and cleft management. Their responses were compared with standards specified by eight cleft palate specialists from four disciplines. The findings indicate that the specialists were somewhat inconsistent in what they expected the families to know about clefts and in their routine counseling procedures to provide the information. In general, the mothers had appropriate knowledge about clefts but predicted that their children knew more about clefts and cleft management than was actually the case. The children had less than adequate information about the general impact of a cleft, the etiology of clefts, the rationale for cleft management they had received, and future management of their problem. The results of the study indicate the need or more systematic procedures for providing information to the child with a cleft. The results also suggest the need for additional research about the general counseling process.

A preliminary study of the predictive value of the IPAT.

Articulation test scores for 278 subjects with cleft palate were compared with the normative data of Templin and Darley on the Iowa Pressure Articulation Test and the Templin-Darley Screening test of Articulation. In addition the predictive value of the Iowa Pressure Articulation Test in relation to the need for secondary management was examined. The results indicate that, at no age level between four and ten years, do more than 9% of the subjects achieve the mean on the IPAT without secondary management. Examination of the data in regard to "risk rates" indicates that the IPAT is very useful in predicting the need for secondary management. Subjects who obtained scores of zero on the IPAT at four and one-half years of age had a 96% risk of requiring secondary palatal management.

A comparative study of results of the von Langenbeck and the V-Y pushback palatoplasties.

The incidence of velopharyngeal competence noted in 267 cleft palate patients following palatoplsty has been reviewed. Comparisons have been drawn with regard to the cleft type and the surgical technique performed. Since there were relatively small numbers of subjects in some categories, differences in age at last examination between the von Langenbeck and V-Y palatoplasty groups, some patients were very young at time of evaluation, and a number of different surgeons at different levels of training and experience performed the surgery, the differences in velopharyngeal competence found should be viewed as trends and this report as preliminary. In general, there was a trend toward smaller percentages of patients attaining acceptable velopharyngeal competence as the severity of the cleft increased. Of those with clefts of the soft palate only 86 per cent achieved competence. Among those patients with clefts of the palate only, 67 per cent achieved competence, whereas only 57 per cent of those with clefts of the lip and palate were able to do so. When comparing all cleft types, the V-Y palatoplasty resulted in a significantly higher percentage of velopharyngeal competence (74 per cent) than did the von Langenbeck method (56 per cent), although the data for the V-Y group are probably less reliable than those for the von Langenbeck group. In the soft palate only category, the results were slightly better with the von Langenbeck technique, though not significantly so. In all other cleft types, the results with the V-Y method were better than those with the von Langenbeck.

Sexual knowledge and attitudes of institutionalized and noninstitutionalized retarded adolescents.

Sixty-one noninstitutionalized and 60 institutionalized mentally retarded adolescents were psychometrically assessed on three measures: sexual knowledge, sexual attitudes, and self-concept. The two groups differed on total score on sex knowledge only, with the non institutionalized group being more knowledgeable. With regard to sexual attitudes and self-concept, the two groups did not differ in terms of total correct statements. Internal consistency demonstrated on all the measures ranged from .50 to .90. Intercorrelations of relevant variables for each group (10 for the noninstitutionalized, 13 for the institutionalized) produced several significant correlations. Results were discussed with reference to the development of a standardized instrument for assessing sex-education programs for mentally retarded persons.
