summaryOne of the most fundamental and unresolved problems in awareness research concerns the primitives used to exert an influence of voluntary attentional control, intuitively expressed as "effort-of-will". Resolving this problem is critical for both computational theory and neurophysiological investigations into awareness. We have developed novel paradigms, employing competing visual stimulation to study perceptual ambiguity resolution. We have demonstrated quantitatively, using a theoretical neural model, that gain modulation at early stages, driven by top-down feedback, is sufficient to explain all reported data on control of perceptual decisions.
