Local and global process of stimuli in autism using face
The aim of the study was how people with autism configure faces. We collected data from autistic and normal children. In a lighted room participants were presented with 24 stimuli constructed by three dots configuring a ...
Colour contrast influences perceived shape in combined shading and texture patterns
(Brill Academic Publishers, 2006)
The 'colour-shading effect' describes the phenomenon whereby a chromatic pattern influences perceived shape-from-shading in a luminance pattern. Specifically, the depth corrugations perceived in sinusoidal luminance gratings ...
Variations in normal color vision. IV. Binary hues and hue scaling
(Optical Society of America, 2005)
We used hue cancellation and focal naming to compare individual differences in stimuli selected for unique hues (e.g., pure blue or green) and binary hues (e.g., blue-green). Standard models assume that binary hues depend ...
Adaptation and visual salience
We examined how the salience of color is affected by adaptation to different color distributions. Observers searched for a color target on a dense background of distractors varying along different directions in color space. ...
Dichoptic difference thresholds for chromatic stimuli
We have investigated the properties of binocular color vision using a new measure: the Dichoptic Color Difference Threshold (DCDT). The DCDT is the smallest detectable difference in color between two dichoptically superimposed ...
Chromatic variations suppress suprathreshold brightness variations
Most objects in natural scenes are suprathreshold in both color (chromatic) and luminance contrast. How salient is each dimension? We have developed a novel method employing a stimulus similar to that used by B. C. Regan ...
