Exam 5: Seeing Pattern and Motion

Campbell and Robson found that, as their contrasts were increased, a low contrast square-wave grating could be discriminated from a low contrast sine-wave grating when:

The peak of the contrast sensitivity function for stationary gratings in moderate luminance occurs at about:

In the Barlow and Levick model of a motion detector, two inputs are compared in a:

Does the visual system perform a Fourier analysis of spatial patterns?

First-order motion detectors respond to moving patterns defined by:

Computation of which of the following has not been suggested as a method of edge location:

Ramachandran and Anstis suggested that false matches were avoided in the perception of random dot kinematograms by:

Holway and Boring's study suggested that:

When two patterns of dots moving horizontally in opposite directions are superimposed, they may produce motion transparency. Which characteristics of the patterns produce transparency?

The minimum stimulus change of a second-order moving pattern which can be detected in a range of conditions corresponds to:

In an x-t plot of a moving stimulus, velocity is given by:

A Reichardt detector signals, in response to flicker:

What was the spatial frequency of the highest spatial frequency channel suggested by Wilson et al. to encode foveal stimuli?

Holway and Boring's study suggested that:

'Retinal size' is probably:

By how many spatial channels did Wilson et al. suggest foveal stimuli were encoded?

Why does adaptation to square-wave gratings provide a strong test of the theory that spatial vision includes a Fourier analysis?

Vaina and Soloviev suggested that second-order motion is processed within the:

Which of the following has not been suggested as a cue for edge location?

Cinema is possible because motion detectors:
