On a moment-by-moment basis we are faced with an environment that is in a continutal 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, preceptual 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. We use a combination of behavioral and neuroimaging techniques (EEG, fMRI) coupled with advanced analytical methods to systematically investigate the dynamics of the perceptual, cognitive, and neural mechanisms of selective attention.
