Carson Yahrmarkt
Carson Yahrmart earned his M.S. in Psychology degree in the summer of 2023. He completed his Master's thesis in our EAB rat laboratory, where his project, titled, Control of Pausing in Rich-Lean Transitions by Spatially Localized and Spatially Diffuse Stimuli, explored the effects that schedule-correlated stimuli have on disruptions in behavior. In the fall of 2023, Carson began the PhD program in Psychology with an emphasis in Behavior Analysis at West Virginia University.

Haillie McDonough, Graduate Student
Haillie McDonough earned her M.S. in Psychology degree (Behavior Analysis track) in the fall of 2025. She completed her Master's thesis in our EAB rat laboratory, where her project, titled, Effects of Response-Independent Food Delivery During Timeout on Timeout Punishment, explored how delivering reinforcers during timeout periods ("treatment integrity failures) alters the functions of timeout. In the fall of 2025, Haillie began the PhD program in Psychology with an emphasis on Behavior Analysis at West Virginia University.
