Gabriel Tillman

Post Doctoral Fellow
Research Area: Cognition and Cognitive Neuroscience


Response Time, Perceptual Decision Making, Cognitive Modelling

Gabriel is interested in how people make simple perceptual decisions about incoming sensory information. During his PhD, he used mathematical models to learn about the mental processes involved in speech perception, word recognition, and driving motor vehicles under increased cognitive load. At Vanderbilt University, Gabriel works with Palmeri, Schall, and Logan in developing neurocognitive models of perceptual decision-making.
