title
The roles of distinct attentional mechanisms and their neural correlates in the frontal eye field to perceptual decision making and oculomotor choice

abstract
The choice of where to look next is guided by the physical salience of items in a visual scene, the observer’s current goals, and the lingering biases of past selections. Thus, each saccadic choice is the result of dynamic interplay between the aforementioned attentional mechanisms, and their respective influences upon both the perceptual, and/or motor aspects of the choice. The nature of this interaction is typically hard to resolve because these mechanisms evolve rapidly and often in parallel. Classic reaction time (RT) tasks typically preclude such dynamic interplay by promoting a serial arrangement of perceptual analysis followed by motor planning. Using the compelled response paradigms wherein motor planning precedes the perceptual evaluation, we can dissociate the perceptual from motor processing stages of a choice, and thus evaluate how perception — and the above-mentioned attentional influences — inform motor planning.
