Adaptation and visual salience
McDermott, Kyle C.; Malkoç, Gökhan; Mulligan, Jeffrey B.; Webster, Michael A. (ARVO, 2010-11)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. ... -
Chromatic variations suppress suprathreshold brightness variations
Kingdom, Frederick A. A.; Bell, Jason; Gheorghiu, Elena; Malkoç, Gökhan (ARVO, 2010-08)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 ... -
Colour contrast influences perceived shape in combined shading and texture patterns
Kingdom, Frederick A.A; Wong, Karen; Yoonessi, Ali; Malkoç, Gökhan (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 ... -
Dichoptic difference thresholds for chromatic stimuli
Malkoç, Gökhan; Kingdom, Frederick A. A. (Elsevier, 2012-06-01)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 ... -
Local and global process of stimuli in autism using face
Malkoç, Gökhan (Routledge, 2008-06)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 ... -
Variations in normal color vision. IV. Binary hues and hue scaling
Malkoç, Gökhan; Kay, Paul; Webster, Michael A. (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 ...
