Dr Nicole Wicha width=
Research Interests

  • Cognitive and neural bases of human language
    • Adult real-time language comprehension
    • Brain basis of bilingualism
    • Intersection between language and other aspects of cognition

 

Dr. Wicha's research focuses on understanding how the brain processes language in real time using both behavioral and brain-imaging techniques, in particular event- related brain potentials (ERPs), which is a non-invasive direct measure of electrical brain activity with excellent precision in the time domain. Dr. Wicha has used these techniques to study the brain processes underlying language comprehension, such as the predictive nature of sentence comprehension in the monolingual and bilingual brain#, and when and how different sources of linguistic information (e.g., grammar and word meaning#) affect our ability to understand an utterance#.Her findings indicate that the brain regions responsible for processing different linguistic information interact over time, and that the brain uses predictive processes to rapidly anticipate upcoming information and facilitate comprehension.

Currently a primary focus in her lab is in understanding the unique processing capabilities of the bilingual brain.  Some of the questions include how the bilingual brain predicts and processes two languages simultaneously, such as when reading a sentence that contains language switches, the implicit effects that one language can have on the other during processing or conversely how bilinguals manage to process one language without interference from the other.  With postdoctoral fellow Elena Salillas, PhD, she is also investigating how arithmetic is processed in the bilingual brain.

Dr. Wicha also collaborates extensively with investigators who use a cognitive neuroscience approach to study various populations and questions.  These include work on how language experience can change basic perception of pitch and tone with Dr. Shalini Narayana (UTHSCSA) and Dr. Peter Pfordresher (SUNY Buffalo), the interaction between gaze direction and facial emotion in face perception with Dr. Reiko Graham (Texas State University), the effect of alcohol on perception of alcohol-related stimuli with Dr. Graham and Dr. Natalie Ceballos (Texas State University) and how executive function is affected in children with ADHD with Dr. Steven Pliszka (UTHSCSA).

Dr. Wicha holds a PhD in Cognitive Science from the University of California at San Diego, where she received interdisciplinary training in behavioral, computational and brain imaging techniques for addressing questions in Cognitive Neuroscience. She continued her training in Cognitive Neuroscience through the Institute of Neural Computation in La Jolla, California as a post-doctoral fellow. She is now an Assistant Professor in the Department of Biology at the University of Texas at San Antonio, and holds a cross appointment with the University of Texas Health Science Center through the Research Imaging Center, where she is the Technical Director of the ERP laboratory.  Dr. Wicha shares with her students her expertise in ERP methodology, experimental training and knowledge of research in cognitive neuroscience, through teaching and laboratory mentorship.

Brain and Behavior of Bilingual Language Comprehension

This grant focuses on understanding the electrophysiological correlates of language comprehension in the bilingual and monolingual brain.  A series of experiments using Event Related Potentials and behavioral measures investigate the timing and type of response associated with processing a code switched word, as well as the prediction and integration of words in sentence context.  In addition the interaction between languages is analyzed in fluent and asymmetric bilinguals.

Role: PI
