Abstract The visual system usually sees phi apparent movement when two similar pictures are exposed successively, and stereoscopic depth when the pictures are exposed one to each eye. But when a picture was followed via a dissolve by its own photographic negative, overlapping but displaced, strong apparent movement was seen in the opposite direction to the image displacement (“reversed phi”). When both eyes saw a positive picture, and one eye also saw an overlapping low-contrast negative… Expand

  • S. Anstis
  • Mathematics, Medicine
  • Philosophical transactions of the Royal Society of London. Series B, Biological sciences
  • 1980
TLDR
Manipulations of the local and global correspondences between pictures included motion phenomena such as reversed apparent movement; a four-stroke oscillatory cycle which gave an illusion of continuous motion in one direction; edges defined by texture, stereoscopic depth, or flicker, kinetic edges; and wave motion.

Visual Dissociations of Movement, Position, and Stereo Depth: Some Phenomenal Phenomena
  • R. Gregory, P. Heard
  • Psychology, Medicine

  • 1983
TLDR
The importance is brought out of the importance, for explaining such perceptual anomalies, of distinguishing between neural signal channel characteristics and which stimulus features from the display are selected and accepted for perception. Expand
Reversed Depth from Positive and Negative Stereograms
A stereogram was presented with patterns of opposite contrast–one positive the other negative. One eye received only the positive pattern; the other received both positive and negative patternsExpand
Reversed Phi and the “Phenomenal Phenomena” Revisited
TLDR
A simple, spatial-smoothing explanation is put forward that can account for both the direction and magnitude of the reversed effects in the motion, stereo and Vernier domains and whether the striking motion effects seen when viewing Kitaoka’s colour-dependent Fraser-Wilcox figures are related to the reversed phi illusion. Expand
Misdirected visual motion in the peripheral visual field
TLDR
This illusion of perceived direction dramatizes differences in motion processing between the fovea and the periphery. Expand
Reversed Depth in Anticorrelated Random-Dot Stereograms and the Central-Peripheral Difference in Visual Inference
TLDR
It is reported that the reversed depth is more easily perceived in the peripheral visual field, supporting a recently proposed central-peripheral dichotomy in the way that feedback from higher to lower visual cortical areas implements visual inference. Expand
Reversed Visual Motion and Self-Sustaining Eye Oscillations
TLDR
A random-dot field undergoing counterphase flicker paradoxically appears to move in the same direction as head and eye movements, ie opposite to the optic-flow field, which can be explained by reversed phi motion caused by apparent pixel movement between successive retinal images. Expand
Two-stroke: A new illusion of visual motion based on the time course of neural responses in the human visual system
  • G. Mather
  • Psychology, Medicine
  • Vision Research
  • 2006
TLDR
A new illusion of movement called "two-stroke" is described, in which repeated presentation of a two-frame pattern displacement can create an impression of continuous forward motion, without the inclusion of any additional pattern displacements. Expand
Recovering motion information from luminance
  • S. Anstis
  • Physics, Medicine
  • Vision Research
  • 1986
TLDR
Evidence that visual transient channels responding to temporal change of luminance provide inputs to motion mechanisms, and also play a part in judgments of static brightness is reviewed, constrain possible models of motion perception. Expand
First- and second-order contributions to depth perception in anti-correlated random dot stereograms
TLDR
Reversed depth from ACR DS (circular no-gap condition) was seen by a minority of participants, but this effect reduced as the gap size increased, and depth was mostly perceived in the correct direction for ACRDS edge stimuli, with the effect increasing with the gapsize. Expand

Apparent movement due to closely spaced sequentially flashed dots in the human peripheral field of vision.
TLDR
Stabilized vision, and a number of variants of the two-flash program, do not abolish the illusion whereas putative dichogeniculate presentation does and the view that the illusion shares a common basis with the phenomena of metacontrast and real-movement perception is not ruled out. Expand
Stereopsis without image segregation.
TLDR
The shape of the function relating depth magnitude to proportions of half-field intensity varied with binocular disparity in the displays. Expand

Evidence for a Physiological Explanation of the Waterfall Phenomenon and Figural After-effects
TLDR
The rabbit's retina ganglion cells have recently been found which signal the direction of motion of objects moving in the visual field, and the behaviour is what one might expect in units of which the function is to abstract direction ofmotion from the pattern of light falling on the retina. Expand
Neurophysiology of Binocular Single Vision and Stereopsis
In the last few years observations made from single cells in the striate cortex have revealed neural mechanisms which doubtless underlie many of the phenomena of binocular vision. These newExpand
Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
TLDR
This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.

The complementarity of apparent and real motion
TLDR
It is suggested that apparent motion serves biologically to extend the range of motion perception beyond that allowed by time-constants early in the visual system. Expand
Receptive fields of single neurones in the cat's striate cortex
TLDR
The present investigation, made in acute preparations, includes a study of receptive fields of cells in the cat's striate cortex, which resembled retinal ganglion-cell receptive fields, but the shape and arrangement of excitatory and inhibitory areas differed strikingly from the concentric pattern found in retinalganglion cells.
