Our perceptual and attentional systems have evolved not so much to provide veridical and invariant representations of the external world, but rather to highlight motivationally relevant affordances (e.g., dangers and potential sources of reward). Accordingly, how we perceive our environment at any given moment is subject to the fluctuating exigencies of endogenous goal states and, relatedly, the acquired salience of the stimuli that we encounter. In broad terms, my research addresses this interplay of emotion, attention and motivation. Specifically, my work employs electrophysiological and behavioral methods to examine the ways in which the human cerebral cortex (particularly cortical perceptual systems) are tuned (or become tuned) to selectively respond to basic affective properties, namely hedonic valence and arousal. In natural environments organisms preferentially orient, attend and respond to such elementary affective dimensions, yet our knowledge concerning the large-scale neural dynamics that underlie this form of so-called “natural selective attention” remain relatively scarce.
