- Bidwell's ghost
- Also referred to as Purkinje afterimage. The eponym Bidwell's ghost refers to the British physicist Shelford Bidwell (1848-1909). It is used to denote a * negative afterimage that appears second in a temporal sequence of *afterimages resulting from exposure to a brief light stimulus. Like other negative afterimages, Bidwell's ghost takes on a hue complementary to that ofthe original optical stimulus. Bidwell's ghost is commonly classified as a *physiological illusion.ReferencesBrown, J.L. (1965). Afterimages.In: Vision and visual perception. Edited by Graham, C.H. New York, NY: Wiley.
