Perceived duration of chromatic and achromatic light
Luminance and color information are considered to be processed in parallel systems. The integration of information from these two separate systems is crucial for the visual system to produce a coherent percept. To investigate how luminance and color lights are perceived in time, we measured the perceived duration of light stimuli with and without colors in a paradigm involving simultaneous perc...
متن کاملPerception of Lightness and Brightness of Achromatic Surface Color and Impression of Illumination
The relationships between lightness and brightness responses under the condition that achromatic "surface color " appears and the relationships between perceived illumination and brightness were examined. The Ss were required to make categorical judgments upon both lightness and brightness of the test patches presented on black and white backgrounds and upon the over-all illumination in the vis...
متن کاملVisual structures for achromatic color perceptions.
Accuracy of achromatic perceptions (correctly seeing blacks, grays, and whites) was investigated for three-dimensional rooms, painted matte black or white, presented empty or containing matte or specular, and black, middle gray, or white objects. The rooms were illuminated by a point source at various locations or by extended sources. Observers judged the achromatic color of four walls in the r...
متن کاملSensory and physical determinants of perceived achromatic transparency.
What are the physical and sensory determinants of perceived transparency? To explore this question, we simulated pairs of physically different neutral density filters on a CRT and asked observers to match their perceived transparency. Matching was accomplished by adjusting one of two physically independent filter properties, reflectivity and inner transmittance. Results show that observers can ...
متن کاملPrecision, accuracy, and range of perceived achromatic transparency.
How accurately do human observers perceive the properties of an achromatic transparent filter with both reflective and transmissive components? To address this question, a novel six-luminance stimulus was employed, consisting of three transparent layer luminances set against three background luminances, which satisfied the conventional constraints of perceptual transparency. In one experiment, ...
