We are a cognitive neuroscience lab that uses behavioral and neuroscience methods as well as computational modeling to study learning and decision making.

One focus we have is on answering basic cognitive neuroscience questions about things related to reinforcement learning, categorization, and decision-making.

A second focus is to take the experimental paradigms, mathematical models, and analysis approaches we have developed through basic cognitive neuroscience research and use the to ask applied questions.

We are funded by the National Institute on Aging to examine how aging influences decision-making. We are also examining how things like impulsivity, substance use, dopaminergic affinity, personality, and other individual differences affect things like reward processing and decision-making.

Astin Cornwall – 3rd year graduate student


Astin completed his Associate of Arts at Tarrant County College, and his Bachelor of Science in Psychology at Texas Wesleyan University in 2016.  His research mainly focuses on how people make decisions under conditions of uncertainty and learn from the experience.  More recently, his focus has been on using mathematical models to explain uncertain choice behavior in human participants. Other topics of interest which relate to his work include: neuroscience, neuroeconomics, and machine learning.

David Yang – 2nd year graduate student

David_Y (1)

Dong Yu (David) Yang completed his M.S. in Psychology at National Chung Cheng University, Taiwan. In his thesis, he investigated what affects working memory capacity. Working as a research assistant, he began an early cognitive neuroscience career at different institutes. Now he is pursuing a Ph.D. in the WorthyLab. David’s research interests are human decision-making modeling and simulation. He is also interested in cognitive models and functional imaging studies.

Kaitlyn McCauley – Lab Manager


Kaitlyn completed her B.S. in Psychology at Texas A&M University in 2018. She is planning to apply to School Psychology Ph.D. programs for the Fall 2019 term. Her research interests include the role of stress in learning outcomes, self-perception of goal attainment, and the effect of adverse childhood experiences on motivation and/or adaptation to stress. She joined the Worthy Lab to advance her research skills before entering grad school.
