Rapid volitional control of apparent motion during percept generation

Willpower and Conscious Percept: Volitional Switching in Binocular Rivalry

When dissimilar images are presented to the left and right eyes, awareness switches spontaneously between the two images, such that one of the images is suppressed from awareness while the other is perceptually dominant. For over 170 years, it has been accepted that even though the periods of dominance are subject to attentional processes, we have no inherent control over perceptual switching. ...

Back from the future: Volitional postdiction of perceived apparent motion direction.

Among physical events, it is impossible that an event could alter its own past for the simple reason that past events precede future events, and not vice versa. Moreover, to do so would invoke impossible self-causation. However, mental events are constructed by physical neuronal processes that take a finite duration to execute. Given this fact, it is conceivable that later brain events could al...

Rapid detection of salient regions: evidence from apparent motion.

Most studies that have used Kanizsa-type illusory figures to investigate perceptual completion have treated the crisp bounding illusory contours (ICs) and the enclosed region as nondissociable stimulus attributes. However, there is evidence that enclosed "salient regions" (SRs; Stanley & Rubin, 2003) are detected even in cases when bounding ICs are not perceptually completed. Here we used appar...
