ABSTRACT
This article presents information on a recent research on visual psychophysics, conducted by researcher R.W. Ditchburn. According to the article author, analyzing the physical basis of perception is an art shared by few. Ditchburn has written a text of significance on his research, titled "Eye-Movements and Visual Perception." Ditchburn, a physicist, helped a generation of physics students to a better appreciation of optics through his textbook on light. During the last 25 years, however, his main interest has been the visual effects of stabilizing the retinal image, which he was one of the first to achieve. Basic information on the optical and optomotor factors in the formation of the retinal image is presented in his research. There are various information on the physiology of visual sensory processes, as well as of the eye movement apparatus in man. Most of it, however, is concerned with the effect on visual thresholds of various programs of eve movements, and, in particular, the nulling out of normal micronystagmus. A few sections deal with changes in pattern perception when retinal images are stabilized.

    Successfully navigating a dynamic environment requires the efficient distribution of finite neural resources. Voluntary (endogenous) covert spatial attention selectively allocates those processing resources to goal-relevant locations in the visual scene in the absence of eye movements. However,...

    Objects in the world often are occluded and in motion. The visible fragments of such objects are revealed at different times and locations in space. To form coherent representations of the surfaces of these objects, the visual system must integrate local form information over space and time. We...

    :The question of whether perceptual illusions influence eye movements is critical for the long-standing debate regarding the separation between action and perception. To test the role of auditory context on a visual illusion and on eye movements, we took advantage of the fact that the presence...
