On a moment-by-moment basis we are faced with an environment that is in a continual state of flux, changing over time and space. Coherent and adaptive behavior in this complex environment is supported by the interplay of a variety of sensory, perceptual and cognitive systems. Attention provides a powerful coping mechanism that mediates the selective processing of information that is consistent with our current behavioral goals and intentions. The purpose of the research conducted in our lab is to clarify the perceptual, cognitive, and neural mechanisms of selective attention.
