When specific information is missing even easy perceptual tasks can become difficult.

Investigating such top-down influences elucidates the regulation of ascending sensory physiological mechanisms by higher cognitive systems. This research prospect paves the road to a more scientific understanding of how top-down control modulates perceptual processes downstream.
