Purpose: Individuals diagnosed with autism spectrum disorder (ASD) often exhibit auditory processing issues, including poor speech recognition in background noise and dichotic processing (integration of different stimuli presented to the two ears). Auditory training could mitigate these auditory difficulties. However, few auditory training programs have been designed to target specific listening deficits for students with ASD. The present study summarizes the development of an innovative, one-on-one, clinician-developed speech-in-noise (SIN) training program that has not been previously described and an existing dichotic auditory training program to address common auditory processing deficits in students with ASD.

Method: Twenty verbal students with ASD, ages 7-17 years, completed a one-on-one, clinician-developed SIN training program and a commercially available dichotic training program 2-3 times a week (30-45 min per session) for 12 weeks. Maximum and minimum training levels from the SIN and dichotic training programs were analyzed statistically to document changes in training level over the training period.

Results: Analyses of the pre- and posttraining data revealed significant improvements in training level for both the SIN and dichotic training programs.

Conclusions: Overall, the proposed SIN training resulted in significant improvements in training level and may be used along with dichotic training to improve some of the most common auditory processing issues documented in verbal individuals with ASD requiring minimal support. Both types of auditory training may be implemented in one-on-one therapy in clinics and in the schools.

Purpose: Production of complex syntax is a hallmark of later language development; however, most of the research examining age-related changes has focused on adolescents or analyzed narrative language samples. Research documenting age-related changes in the production of complex syntax in elementary school-aged children in conversational language samples is limited. Therefore, the purpose of this article is to examine age-related changes in the production of coordinate and subordinate clauses in children between 5 and 10 years of age obtained from 50-utterance conversational language samples.

Method: The analytic sample included 196 children with typical language development, who ranged in age from 5;0 to 10;11 (years;months; girls = 103; boys = 96; three cases were excluded). Fifty-utterance conversational language samples were examined for use of coordinate and subordinate clauses.

Results: Results of regression analyses indicated that the production of coordinate and subordinate clauses could be predicted from age. The proportion of utterances that included subordinate clauses increased 0.20% for every month increase in age (p < .001). Coordinate clauses also continued to grow, although at a slower rate (0.10% increase for every month increase in age, p < .001). Finally, the proportion of simple utterances (i.e., utterances without coordinate or subordinate clauses) decreased with age (0.40% decrease for every month increase in age, p < .001).

Conclusions: This study indicated that as children's age increased, they used fewer, simple, one-clause sentences and more utterances that included subordinate clauses, with or without coordinate clauses. These results were obtained from 50-utterance language samples, further supporting use of language sampling to develop intervention goals and monitor progress in therapy.

Purpose: We investigated the efficacy of Story Champs for improving oral language in third-grade Spanish-English bilingual children with developmental language disorder (DLD).

Method: We implemented a concurrent multiple-baseline across-participants single-case design with four bilingual Spanish-English third-grade students with DLD. Treatment was carried out over 12 sessions with approximately two sessions per week. Maintenance sessions were conducted 1, 2, and 4 weeks postintervention. Participants were explicitly taught story grammar elements, causal and temporal connections, and modifiers within story retells and personal narratives. Dependent variables were story grammar, grammatical complexity, modifiers and listening comprehension within story retells, and story grammar and grammatical complexity within personal narratives. Outcome measures were assessed at the end of every baseline, intervention, and maintenance session using the Narrative Language Measures-Listening (NLM-L).

Results: Visual analyses for outcome measures suggested slight increases in scores on the NLM-L during intervention accompanied by marked variability. Within-case analyses of story retell performance suggested an intervention effect on story grammar for two participants and on grammatical complexity and modifier use for one participant. For personal narratives, within-case analyses of personal narrative performance suggested an intervention effect on story grammar for one participant.

Conclusions: Overall, Story Champs demonstrated efficacy for improving story grammar use in story retells for three out of four participants. It did not show efficacy for improving grammatical complexity, modifier use, or listening comprehension within story retells, nor did it show efficacy for improving story grammar and grammatical complexity within personal narratives.
