D8a - Optimizing a Clinical Language Measure for use in Identifying Significant Neurodevelopmental Impairment in Diagnosis of FASD John C. Thorne This session will describe a procedure for collecting and analyzing a narrative language sample for the purpose of identifying neurodevelopmental impairment in children prenatally exposed to alcohol. The focus will be on how to balance sensitivity for impairment against false positive results when using performance errors as a signal of impairment. Learning Objectives: 1. Describe how linguistic errors produced during a standardized language task can be used to reveal neurodevelopmental impairment associated with prenatal alcohol exposure 2. Describe the impact that adjusting diagnostic cut-points used with behavioral measures has on the rates of true positive and false positive diagnoses during FASD diagnostic assessments 3. Meaningfully describe the clinical impact of true and false positive diagnoses in the context of FASD diagnosis D8b - Characterizing Central Auditory Processing and Sound-in-Noise Listening Deficits in Individuals with FASD Susan McLaughlin, John C. Thorne, Adrian KC Lee Prenatal alcohol exposure may cause central auditory deficits leading to difficulties hearing speech in noise. Preliminary data will be presented from a study investigating auditory processing in FASD utilizing a battery of psychoacoustic measures and multimodal neuroimaging techniques to characterize the integrity of the auditory pathway, from periphery to cortex. Learning Objectives: 1. Gain an appreciation for the evidence that auditory impairments in the absence of a hearing loss may be associated with FASD 2. Explain the functional relevance of sound-in-noise listening for language acquisition/competence and describe some of the key components of the central auditory processing stream (e.g. subcortical sensitivity to temporal features of sound, cortical representation of auditory spatial cues, and cortical networks associated with switching auditory attention) that underlie the capacity to hear sound in noise 3. Understand how state-of-the-art auditory neuroscience paradigms can assay the integrity of specific auditory processes and potentially reveal detailed information about the prevalence and nature of central auditory processing deficits in individuals with FASD
