Pavlovian Fear-Conditioning

Pavlovian conditioning is a choice paradigm to study a diverse set of behaviors and biological processes. In psychology, the century old finding that learned responses can be elicited by previously neutral stimuli serves as the foundation for an increasing number of influential theories of learning, emotion, memory, decision making, and social psychology. In neuroscience, it serves as the basic infrastructure for controlled neurobiological investigations of learning and memory at the molecular, cellular, and systems level. In psychiatry, it is increasingly relied upon as a model to investigate and potentially treat a host of mental health disorders. We incorporate the principles of conditioning into much of our work on learning, memory, and control of unwanted behaviors and negative emotional memories.

We currently use two large testing rooms on the fourth floor of the Health Discovery Building. Each testing room has a set of Biopac MP160 GSR and PPG modules as well as a shock box used for stress and fear conditioning. Most experiments are run on either E-Prime, Matlab, or Psychopy.

functional MRI

We currently use the fMRI scanner at the Imaging Research Center (IRC) in the Norman Hackerman Building of UT Austin, but soon we will run participants in the Imaging Research Center (yes, we know, they confusingly have the same name) on the first floor of the Health Discovery Building.

Virtual Reality

We conduct a variety of behavioral and physiological experiments in virtual reality with an Oculus Rift headset. Our environments are programmed in Unity software.
