This study examined how intervention dose frequency affects phonological acquisition and generalization in preschool children with speech sound disorders (SSD). Using a multiple-baseline, single-participants experimental design, eight English-speaking children with SSD (4;0 to 5;6) were split into two dose frequency conditions (4…

Background: A pattern of ingressive substitutions for word-final sibilants can be identified in a small number of cases in child speech disorder, with growing evidence suggesting it is a phonological difficulty, despite the unusual surface form. Phonological difficulty implies a problem with the cognitive process of organizing speech into sound…

Following a treatment program in which an invented morpheme was taught through either imitation or modeling procedures, generalization of 40 specific language-impaired young children was compared to that of 40 non-impaired children. The abnormal group generalized more following imitation teaching while the normal group generalized more following…

A three-factor model for the management of early childhood stuttering is proposed that takes into account stuttering's psychosocial, psycholinguistic, and physiological aspects. The primary focus of the present article is the psycholinguistic factor. To this end, a rationale for the use of language-based therapy is presented, together with…

Four individuals with agrammatic aphasia were trained to comprehend and produce filler-gap sentences with wh-movement. Two participants received treatment first on the least complex structure (who-questions), and 2 received treatment on the most complex form (object-relative constructions). Object-relative training resulted in robust…

A study of three hearing, moderately handicapped children (seven and eight years old) was undertaken in order to examine the acquisition, generalization, and maintenance of sign language production with this population. (PHR)
