orientations, colors, directions of motion, ...
Some effects of negative delays upon the perception of causal relatedness
(The International Society for Psychophysics, 2004)
We examined the effects of negative delays on the perception of causality using a variation of the paradigm originated by Michotte (1954) and as an extension to similar work conducted by Kanizsa and Vicario (1968). In our ...
The visual hallucinatory response to flickering polychromatic light.
(The International Society for Psychophysics, 2004)
Our understanding of human visual perception generally rests on the assumption that conscious visual states represent, in some qualitative fashion, a complex interaction between spatially structured variations in the ambient ...
