Actively Recruiting Undergraduate Researchers

Our research aims to tackle a wide range of challenging questions to better understand perception and action. We employ different strategies to answer these questions, such as approaching perception from the perspective of sports, robotics, and illusions. 

The PEARL Lab studies topics in the domains of Perception, Ecological Action, Robotics, and Learning. Recent directions include studying subjective perception, time perception, color perception (and tetrachromacy), sound symbolism, and music. Students interested in game design, Unity, or instrumentation are strongly encouraged to join. Students can choose level of involvement ranging from helping run participants to actually developing and working on independent research projects. This is a great opportunity for students interested in pursuing graduate school in experimental science.

The lab's major research streams are:

  • Perception-Action and Navigation in Sports
  • Robotics and Cognitive Engineering
  • Object, Space and Orientation Perception
  • Auditory Pitch, Pattern, and Form Perception
    • Time Perception & Subjective Perception

Lab Director and Principal Investigator:  Michael McBeath, PhD, Professor 

Dr. McBeath was trained in the emerging area combining Psychology and Engineering. He majored in both fields for his Bachelors degree from Brown University, received a Masters of Science in Instrumentation from the University of California, Santa Barbara, and earned his Doctoral degree from Stanford University in Psychology with a minor in Electrical Engineering. Parallel to his academic career, he worked as a research scientist, both at NASA - Ames Research Center, and at the Interval Corporation, a technology think tank funded by Microsoft co-founder, Paul Allen. His research has been funded by grants from the Interval Corporation, the National Science Foundation and the Office of Naval Research.
