    INVESTIGATING THE EFFECT OF PARENTAL QUESTION INPUT ON CHILDREN WITH ASD
    (2019) Curdts, Lydia Leslie; Bernstein-Ratner, Nan; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The current study analyzed individual mechanisms of language gains following the Solomon et al. (2014) randomized control trial (RCT) of the Play and Language for Autistic Youngsters (PLAY) Project, a DIR/Floortime based early intervention program for children with autism spectrum disorder. 80 parent-child play interactions from the original RCT were analyzed to assess the relationship between various forms of parental question input, as taught in PLAY parent trainings, and child language measures. While high parental question input did correlate with high child language measures, one targeted intervention component, parental Asked/Answered question input, did not increase following parent training and did not improve child language measures. We consider other mechanisms responsible for successful child language gains following PLAY intervention.

    An Exploration of Auditory Brainstem Encoding of Stop Consonants in Infants and Implications for Language Outcomes
    (2016) Rosner, Rachel Stein; Anderson, Samira B; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Current trends in speech-language pathology focus on early intervention as the preferred tool for promoting the best possible outcomes in children with language disorders. Neuroimaging techniques are being studied as promising tools for flagging at-risk infants. In this study, the auditory brainstem response (ABR) to the syllables /ba/ and /ga/ was examined in 41 infants between 3 and 12 months of age as a possible tool to predict language development in toddlerhood. The MacArthur-Bates Communicative Development Inventory (MCDI) was used to assess language development at 18 months of age. The current study compared the periodicity of the responses to the stop consonants and phase differences between /ba/ and /ga/ in both at-risk and low-risk groups. The study also examined whether there are correlations among ABR measures (periodicity and phase differentiation) and language development. The study found that these measures predict language development at 18 months.
