Attentional effects on afterimages: Theory and data
We explore attentional effects on afterimages in the framework of the FACADE model of visual perception. We first show that the FACADE model can account for the experimental findings of Suzuki and Grabowecky [Suzuki, S., & Grabowecky, M. (2003). Attention during adaptation weakens negative afterimages. Journal of Experimental Psychology: Human Perception and Performance 29, 793-807] that afteri...
متن کاملEffects of voluntary attention on structured afterimages.
The effect of voluntary attention on afterimage fragmentation was explored in two experiments. The afterimage, in the form of a 30 degrees-tilted star of David, was generated after prolonged steady fixation in the first experiment, and with a brief and intense flash in the second experiment. Subjects were instructed to select various target shapes in the afterimage for attention and, at the sam...
متن کاملStabilized Integration of Hamiltonian Systems with Hard-Sphere Inequality Constraints
We consider numerical methods for resolving the dynamics of a Hamiltonian Nbody problem subject to hard-sphere inequality constraints. The dynamics of these mixed systems consists of smooth flow of a Hamiltonian system between collisions with an impulsive momentum exchange at the points of collision. The inclusion of these impulses makes traditional backward error analysis inappropriate since t...
متن کاملOrientation and spatial frequency effects on linear afterimages
Single lines and gratings oriented vertically or at 45 dcg were observed as prolonged afterimages in two experiments. The duration of complete visibility exhibited consistent orientation selectivity for the gratings but not for single lines; vertical gratings were visible for longer than were 45-deg gratings. The results are discussed in relation to the hypothesized spatial frequency channels i...
متن کاملAfterimages and Sensation
According to purists, visual experience can be exhaustively characterised in terms of a subject’s apparent perspective on external, public reality. Visual experience presents us (or if we are subject to illusion, apparently presents us) with aspects of the world beyond us—nothing more, nothing less. According to sensationalists, we cannot adequately characterise experience solely in terms of a ...
