Human psychophysics is the quantitative measurement of our own perceptions. In essence,
it is simply a more sophisticated version of what humans have done since time immemorial …

Stereopsis has traditionally been considered a complex visual ability, restricted to large-
brained animals. The discovery in the 1980s that insects, too, have stereopsis, therefore …

The human visual system is foveated: we can see fine spatial details in central vision,
whereas resolution is poor in our peripheral visual field, and this loss of resolution follows an …

Binocular stereo cues are important for discriminating 3D surface orientation, especially at
near distances. We devised a single-interval task where observers discriminated the slant of …

Although human observers can perceive depth from stereograms with considerable contrast
difference between the images presented to the two eyes (Legge & Gu, 1989), how contrast …

One of the greatest challenges in visual neuroscience is that of linking neural activity with
perceptual experience. In the case of binocular depth perception, important insights have …

The binocular energy model of neural responses predicts that depth from binocular disparity
might be perceived in the reversed direction when the contrast of dots presented to one eye …

Human stereopsis can operate in dense “cyclopean” images containing no monocular
objects. This is believed to depend on the computation of binocular correlation by neurons in …

In binocular vision, occlusion of one object by another gives rise to monocular occlusions—
regions visible only in one eye. Although binocular disparities cannot be computed for these …

We present a simple model which can account for the stereoscopic sensitivity of praying
mantis predatory strikes. The model consists of a single “disparity sensor”: a binocular …
