Research programs in the Human Perception and Performance Group are organized to develop basic scientific knowledge about human perception and performance, and to apply this knowledge to support or improve these processes. Human perception and performance is studied in the context of the sensory, physical, and psychological changes that may occur over the lifespan. In addition, researchers create and study the utility of computational cognitive models, imaging technologies, and systems that detect and monitor sensory, motor, and neurocognitive functions in perception and performance.
The specific research interests of the group include the following topics:
- The study of healthy aging and brain plasticity
- The effects of physical activity on cognition and psychological function
- Learning and decision making in complex environments
- Spatial navigation in virtual worlds
- Visual and auditory perception and cognition
- Emotional user-product relationships
- Computer-mediated communication
The group employs a large battery of techniques to address the issues described above. These methodologies include eye movement contingent upon control of visual displays; the recording of physiological measures (such as event-related potentials, cardiovascular measures, metabolic function, and fMRI); mathematical and statistical modeling of human responses to simple and complex displays; nonlinear analyses of complex movements; and complex real-time simulations of complex environments.
