    Early Phonological Predictors of Toddler Language Outcomes
    (2015) Gerhold, Kayla; Bernstein Ratner, Nan; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Several studies have explored relationships between children's early phonological development and later language performance. This literature has included a more recent focus on the potential for early vocalization profiles in infancy to predict later language outcomes, including those characterized by delay or disorder. The present study examines phonetic inventories and syllable structure patterns in a large cohort of infants as they relate to expressive language outcomes at 2 years of age. Results suggest that as early as 11 months, phonetic inventory and mean syllable structure level are related to two year expressive language outcomes (MLU, MCDI, and types). If specific patterns of production can be established for a typically-developing population then this will additionally inform clinical decision-making. Possible applications are discussed.

    A Voxel Based Approach to Identifying Lesion Sites in Aphasia: Comprehension and Production Deficits in Syntax, Semantics and Phonology
    (2007-08-20) Kling, Therese Danielle; Shah, Yasmeen; Braun, Allen; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The cortical regions of the brain traditionally associated with deficits of production and comprehension in language are Broca's and Wernicke's areas. Recent evidence suggests that other brain regions are involved and may be specific to linguistic areas of syntax, semantics and phonology. This paper describes the MRI results and language scores of 31 left hemisphere stroke patients with aphasia. Patients' lesions obtained from these MRI scans were reconstructed onto templates and entered into a voxel-based analysis program called Analysis of Brain lesion (ABLe) (Solomon, Raymont, Braun, Butman & Grafman, 2007) along with language scores. The results provided evidence for five key neuroanatomical regions of interest. These include the insula, the planum temporale, the operculum, the temporoparietal occipital (TPO) junction and the putamen. The results revealed common as well as unique areas of brain lesion for each of the behaviors.
