Callier Center for Communication Disorders


The UT Dallas Callier Center houses a variety of research laboratories focusing on communication sciences and disorders.

We welcome students interested in communication sciences and disorders to observe or assist with our research projects.  We also seek research participants from time to time, for studies of typical communication and communication disorders in infants, toddlers, children, adolescents and adults.

Please visit the following Web pages to learn more about our labs and the opportunities to get involved in Callier Center research projects.

The Bilingual Language Laboratory (BLL)
Our main goal is to investigate dual language development in children who are in the process of acquiring a second language, including children who are typically developing as well as those affected by speech and or language impairments. The BLL is particularly interested in how the dual language skills of bilingual children dynamically grow and co-affect each other and related processing skills, as children get older.

CHildren and Infant Listening Laboratory (CHILL)
The CHildren and Infant Listening Laboratory (CHILL) group explores how infants, children, and adolescents with hearing loss wearing cochlear implants learn to communicate with others, and how communication affects how they feel about themselves.

Developmental Neurolinguistics Laboratory
The main focus of the Developmental Neurolinguistics Laboratory is researching the neurological correlates of language and cognitive development using electrophysiological responses, such as Event Related Potentials (ERPs). 

Discourse Studies in Aphasia and Normal Aging Laboratory
The Discourse Studies in Aphasia and Normal Aging lab conducts studies related to discourse of adult populations, including individuals with aphasia, as well as the normal aging population.

Early Communication, Language and Social Skills (CLASS) Laboratory
The Early Communication, Language and Social Skills (CLASS) lab focuses on the association among emotional regulation, early social-communication and the development of joint attention and language in typically developing children with autism.

Hearing Assistive Technology Laboratory
The Hearing Assistive Technology lab conducts electroacoustic evaluations to verify the advanced features of the hearing assistive technology. Behavioral evaluations are then conducted to determine the most appropriate candidates for the new features.

Infant Learning Laboratory
The Infant Learning Laboratory examines preverbal infants’ perception of social communicative signals and other stimuli relevant for early communicative and language development.

Language and Literacy Laboratory
Work in the Language and Literacy Laboratory focuses primarily on preschool-aged children, with an emphasis on research in preliteracy development, socialization, assessment and intervention.

Speech, Language, Cognition and Communication Laboratory  
The Speech, Language, Cognition and Communication Lab is home to studies of speech and language in children, including the factors that influence the development of speech and language skills and prevention, early identification and treatment of speech and language disorders.

Preverbal Communication Projects Laboratory
The Preverbal Communication Projects focus on the acquisition of early communication skills in children who have severe developmental and communicative impairments. Populations currently studied include children who are deafblind and have additional developmental disabilities, as well as children on the autism spectrum. 

Speech Production Laboratory (Acoustics/Perception/Kinematics)
The Speech Production Laboratory studies speech of adults and children. There is a particular focus on the speech of brain-injured talkers with disorders known as aphasia and apraxia-of-speech.

Think Lab
The Think Lab focuses on how children and adults think about the world around them. Research in the lab examines the development of critical thinking skills from the early preschool years through late adolescence.

Wireless Technology for the Hearing Impaired Laboratory
The Wireless Technology for the Hearing Impaired lab focuses on wireless technology for persons with hearing loss, particularly the rapid changes toward integration across multiple devices.
