Making ambiguous displays unambiguous: The influence of real colors and colored aftereffects on perceptual alternation

The relationship between orientation-contingent colored aftereffects (CAEs) and perceptual alternation of ambiguous displays was investigated in three experiments. In all experiments, the ambiguous test displa...

Investigations of perception and imagery using CAEs: The role of experimental design and psychophysical method

Orientation-contingent color aftereffects (CAEs) were measured using 174 observers ran-domly allocated to one of eight experimental conditions formed by the factorial combination of three two-level factors. Th...

The influence of imagery ability on color aftereffects produced by physically present and imagined induction stimuli

Two methods of induction were used to produce orientation-contingent color aftereffects for observers assigned to one of three groups (high, medium, and low) on the basis of self-rated imagery ability. In Expe...

Loss of wavelength selectivity in contour masking and aftereffect following dichoptic adaptation

Two experiments measured the apparent orientation (aftereffect) and the threshold for detection (masking) of a colored grating viewed by one eye after exposure to a colored grating to the same or the opposite ...

Orientation-specific aftereffects and illusions in the perception of brightness

Orientation-specific brightness aftereffects were found when vertical and horizontal gratings of the same space-average luminance were viewed following alternate exposure to vertical and horizontal gratings th...

Brightness selectivity in the motion aftereffect

Eighteen Ss were required to track the apparent motion of a stationary grating viewed after prolonged inspection of a moving grating. Measures were obtained with the inspection and test gratings identical in c...

Tilt discrimination and aftereffect with stroboscopic display of contours

Previous studies have shown that motion perception is degraded when the visual stimulus is stroboscopically illuminated. The present experiment indicated that the accuracy in discrimination of the orientation ...

Imagined lines fail to induce contour masking

Twelve Ss proficient in visual imagery were tested in a study to compare contour masking by real and imaginary lines. Detection of a vertical line was impaired following inspection of a vertical grating but wa...

Lack of directional specificity in tilt aftereffect induced with moving contours

Eight Ss were required to set a grating to vertical following exposure to a tilted grating. Aftereffect was measured with both gratings stationary, with one grating stationary and the other moving, or with bot...
