● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● The basic colors in the color circle are ○ red, green, blue and yellow. Uchikawa et al. demonstrated how _________ can explain why color constancy occurs. ○ chromatic adaptation According to the ratio principle ○ lightness constancy will occur as long as the ratio of light reflected from a white surface and a black surface remain constant. Which of the following was NOT an opponent mechanism proposed by Hering? ○ Blue (+); Green (-) The trichromatic theory of color vision states that color perception is due to ○ the pattern of activity in three different receptors. Two stimuli that are physically different, but are perceptually identical, are called ○ Metamers Yellow and Blue light are projected on a white screen. What color will the screen appear to be? ○ White The reflectance curve is a plot of the light reflected off a surface as a function of ○ Wavelength A unilateral dichromat ○ has trichromatic vision in one eye and dichromatic vision in the other eye. Blue and yellow paints mixed together yield ○ Green Kamitani and Tong (2005) developed "orientation decoders". When eight orientations were tested, the decoders were able to correctly predict what orientation a person was looking at on _____ of the trials. ○ 100% When Palmer (1975) showed observers a kitchen and then a target picture, which picture was identified correctly 80% of the time? ○ a loaf of bread, because it matches the context of the scene The signaling function of color can be exemplified by ○ both knowing to stop at a red light and knowing banana ripeness A monkey with good color vision ○ would have a better chance of surviving than a color-blind monkey Adding more white to a color changes the color’s ○ Saturation The basic colors in the color circle are ○ red, green, blue and yellow By changing _______, we can create about a million (or more) discriminable colors ○ saturation, intensity, and wavelength The reflectance curve is a plot of the light reflected off a surface as a function of ○ Contrast The reflectance curve for a white piece of paper would ○ reflect long, medium and short wavelengths equally The reflectance curve for a purple piece of paper would ○ reflect long and short wavelengths Yellow and Blue light are projected on a white screen. What color will the screen appear to be? ○ White When light is mixed it is referred to as _______ ○ an additive color mixture ● ● ● ● ● ● When paint is mixed it is referred to as _______ ○ a subtractive color mixture The rarest form of dichromatism is: ○ Tritanopia A unilateral dichromat ○ has trichromatic vision in one eye and dichromatic vision in the other eye. The reflectance curve is a plot of the light reflected off a surface as a function of: ○ Wavelength The case of "Mr. I," described in the beginning of the chapter, supports the idea that color is processed in: ○ A "color center" in the cortex Color matching experiments show that if a person with full color vision is given at least ____ wavelengths to mix together, the person can match any single wavelength. ○ 3
