Cognitive Linguistics Lab

Our lab studies what sorts of factors help or hinder language learning in both typically developing and developmentally delayed populations. Specific areas of research include understanding the role that sensory processing and sensory integration play in language learning and development, measuring and improving methods designed to help children diagnosed with autism learn to communicate more effectively, and research on cognitive aspects of language learning and processing in young children and adults.  
Our lab frequently conducts experiments in collaboration with our department’s clinics, especially those offering speech-language services to children. We are also dedicated to collaborating with clinics in the region and a wide range of faculty at both the University of Tennessee as well as other universities. Some of the lab’s research is supported by the UT Alliance of Women Philanthropists. 


  • Neurophysiological evidence for construction meaning
  • Effects of sensory environment of engagement during speech therapy sessions for children at risk for autism
  • The use of imitation to improve engagement during improvised music therapy for children on the autism spectrum
  • Temporal neuro-dynamics of native and nonnative phoneme processing 
  • Multimodal Processing: We are examining expressive and receptive cross modal coordination in children with ASD, typical development, and other developmental delays. Understanding the coordination of various modalities in ASD, and how these characteristics relate to core and developmental features of ASD, will provide insight into underlying mechanisms of ASD. This research has implications for early detection and prognosis.
  • Comparing Attention, Language, and Sensory Processing in ASD and ADHD: This is a qualitative study examining differences in the manifestations of aberrant attention in children with ASD compared to children with ADHD. Children with ASD demonstrate unusual characteristics of attention that can be misdiagnosed as ADHD. This can delay appropriate treatment and sometimes medications are prescribed that have a negative impact on the child. 
  • Happy Mom, Healthy Baby: This will be an intervention study with teen-age mothers who are at risk for high parental stress and their infants who are at high-risk for social, language and literacy difficulties. 
  • Vocal characteristics & developmental skills in ASD: This project assesses associations between vocal characteristics and other communicative and developmental skills in children diagnosed with autism. 
  • Joint Attention: The purpose of this study is to test an intervention designed to promote joint attention skillis in children at risk for developing autism. 
  • Language Function in Autism 
    This study underscores the importance of functional language measures in guiding and evaluating treatment for children with autism, and suggests that play-based interventions can improving children’s use of language during parent–child interactions 
  • Sensory Processing
    A myriad of treatment options are available for children with autism, yet little is understood regarding characteristics of parents (e.g., education) and children (e.g., severity of autism symptoms) that influence types and amounts of therapy utilization. Interviews from 70 families were analyzed to determine potential influences on utilization (e.g., start of first services, use of traditional services).
