The Adaptation Effect in Bilingual People who Stutter: An Examination of the Oral-Motor Rehearsal Theory

The present study provided further information about stuttering among bilingual populations and attempted to assess the significance of repeated oral-motor movements during an adaptation task in two bilingual adults. This was accomplished by requesting that bilingual people who stutter to complete an adaptation task of the same written passage in two different languages. Explored was the following research question: In bilingual speakers who stutter, what is the effect of altering the oral-motor movements by changing the language of the passage read during an adaptation task? Two bilingual adults were each requested to complete an adaptation task consisting of 10 readings in two separate conditions. Participants 1 and 2 completed two conditions, each of which contained a separate passage. Condition B consisted of an adaptation procedure in which the participants read five successive readings in English followed by five additional successive readings in Language 1 (L1). Following the completion of the first randomly assigned condition, the participant was given a rest period of 30 minutes before beginning the remaining condition and passage. Condition A consisted of an adaptation procedure in which the participants read five successive readings in L1 followed by five additional successive readings in English. Results across participants, conditions, and languages indicated an atypical adaptation curve over 10 readings characterized by a dramatic increase in stuttering following a change of language. Closer examination of individual participants revealed differences in stuttering and adaptation among languages and conditions. Participants 1 and 2 demonstrated differences in adaptation and stuttering among languages. Participant 1 demonstrated an increase in stuttering following a change in language read in Condition B and a decrease in stuttering following a change in language read in Condition A. It is speculated that language proficiency contributed to the observed differences in stuttering following a change of language. Participant 2 demonstrated an increase in stuttering following a change in language read in Condition A and a minimal increase in stuttering following a change in language read in Condition B. It is speculated that a change in the oral-motor plan contributed to the increase in stuttering in Condition A. Collectively, findings from this exploratory study lend support to an interactive effect between language proficiency and a change in the oral-motor plan contributing to increased stuttering following a change of language during an adaptation task.

Phonological Development in Hearing Children of Deaf Parents

Phonological development in hearing children of deaf parents Dr. Diane Lillo-Martin 5/9/2010 The researcher wishes to determine the significance of a unique linguistic environment on the effects of phonological development. The research examines whether 3 hearing children of deaf parents, hereafter referred to as CODAs, have inconsistencies, as compared to children in a typical linguistic environment, in their syllable structure, phonological processes or phonemic inventories. More specifically, the research asks whether their speech is more consistent with children of typical environments or more similar to children with phonological delays or disorders or articulation disorders. After the examination of these three components to a child's phonological development, it can be concluded that the linguistic environment of CODA children does not negatively hinder their phonological language development.

Assessment of English Language Learners Seeking a Graduate Degree in Speech Language Pathology

A shortage of bilingual/bicultural speech language pathologists may reflect a problem with recruitment and retention of bilingual/bicultural students. The purpose of the present study was to survey graduate training programs in speech language pathology to determine typical policies and practices concerning students who apply and are admitted as ELLs. With a growing number of ELL children needing services from a bilingual SLP, it seems that little is being done to address the issue. The problem may be with the reluctance of programs to not only accept ELL students, but there also seems to be a disinclination for any sort of training program to be established for these ELL students. Clinic directors were asked to complete a survey about ELLs seeking clinical training in speech language pathology. In particular, we were interested in obtaining information about whether clinical training programs a) provided opportunities for ELL to participate in clinic, b) assessed the English skills of these students, and c) provided remediation if these students English skills were judged to be less than proficient.

Joint Attention in Young Children with Autism

Autism spectrum disorders (ASDs) are classified as pervasive developmental disorders characterized by social, communicative, and behavioral impairments. According to formal and informal reports, children with ASD present with receptive and expressive language delay. Joint attention (JA: the behavior that occurs when two individuals focus on the same object or event) has been identified as a possible marker of delayed language development in children with ASD. In this study, the JA behaviors in children with ASD were contrasted with initially language-matched typically developing (TYP) children across three visits. Measures of language, the frequency, duration, and source of initiation of JA episodes, and the choice of toy during those episodes, were coded. Across visits and groups, mothers initiated more JA episodes than children; however, typical children also initiated more JA episodes than ASD children at visits 1 and 2. Also, the total duration of typically developing children’s JA episodes was generally longer than that of the ASD children’s, significantly so at Visit 2. Significant associations emerged between children’s vocabulary and two measures of JA: frequency and number of maternal initiations. Teaching parents to incorporate JA training in their interactions with their children may likely help children with ASD acquire language.

Vocabulary Comprehension in Children with Autism

An open question in autism research is how to assess language abilities in this population. We investigated language development in monolingual and bilingual children with varying degrees of autism, ages 3 to 9, with the aim of better understanding vocabulary comprehension. Two different methodologies were used: the Receptive One-Word Picture Vocabulary Test (ROWPVT) and eye-tracker technique. We examined whether the eye-tracker could help in the assessment of these children because it does not require the child to point during the test. Four typically developing control children, 14 monolingual English children with moderate/mild autism, and 4 children (2 monolingual English, 2 bilingual Spanish/English) with severe autism were tested and the results of the ROWPVT test were compared to the eye-tracker results. Interestingly, bilingual children with severe autism had better results using eye-tracker than the traditional ROWPVT test. These results suggest that these children know more vocabulary than traditional test measures indicate.
