Our visual system can process information at both conscious and unconscious levels.
Understanding the factors that control whether a stimulus reaches our awareness, and the …

Subjective contours are characterized by both the appearance of an illusory border and an
increase in apparent brightness within the illusory border. Theories have typically addressed …

The stimulus characteristics which constitute edge information for the visual system were
studied by investigating the manner in which edge luminance is related to reduction in …

Acute consumption of ethyl alcohol affects a variety of visual functions. However, there have
been few systematic attempts to investigate the neural mechanisms underlying these effects …

The dynamic properties of induced tilt were measured with a temporal paradigm similar to
the ones employed for studies of changes in sensitivity during early light and dark …

After an S views a grating which is partially blocked from view, adaptation (reduction in
apparent contrast) occurs to a subsequent grating presented within a portion of the visual …

Obtained forward and backward masking functions for 4 adult Ss in a nonmetacontrast letter
recognition paradigm for letters presented either foveally or 1.75. in the periphery with a …

Westheimer (1965) has shown that the rod threshold at the center of a 45′ disk of light is as
much as a log unit higher than it is upon disks of larger diameters. In the present paper we …

Reviews articles appearing from 1969-1971 concerned with spatial, retinal, temporal, and
developmental factors in visual sensitivity. Studies of adaptation, luminance discrimination …

Report of a second target (T2) is impaired when presented within 500 ms of the first (T1).
This attentional blink (AB) is known to cause a delay in T2 processing during which T2 must …
