As the distance from the fovea increases, the concentration of
A) cones sharply decreases.
B) rods sharply decreases.
C) cones gradually increases.
D) both rods and cones gradually increases.
A) cones sharply decreases.
When Rick first steps from bright light into a dark room, he finds it difficult to see anything. After a couple of minutes however, he gradually sees more and more. This is possible because Rick's \_\_\_\_\_ regain their sensitivity. A) photons B) cones C) feature detectors D) rods
D) rods ?
Hendricks walks outside to a bright sunny day after being inside a darkened room. The rapid decrease in sensitivity in his visual neurons is known as A) light adaptation. B) dark adaptation. C) daytime adaptation. D) brightness reduction.
A) light adaptation.
While working the lights for the school play, Kate notices that if she shines a blue light and a yellow light on the same spot, the light will appear white. \_\_\_\_\_\_\_\_\_\_ would predict the occurrence of this visual phenomenon. A) The trichromatic theory B) Subtractive colour mixing C) The law of complementarity D) The three-primaries law
C) The law of complementarity
Which law of colour mixing states that three different wavelengths of light can be used to match any colour that the eye can see if they are mixed in the appropriate proportions? A) the law of additivity B) the law of complimentarity C) the three-primaries law D) the law of subtractivity
C) the three-primaries law
Paul argues that colour vision emerges from the combined activity of three different types of receptors, each most sensitive to a different range of wavelengths. His friend Harry argues that Paul’s theory fails to explain the law of complementarity (how certain colours of wavelengths produce the experience of white). Paul most likely supports the _____ theory, while Harry supports the _____ theory.
A) feature-integration; recognition-by-components
B) opponent-process; trichromatic
C) trichromatic; opponent-process
D) recognition-by-components; feature-integration
C) trichromatic; opponent-process
Physiological research in the 1950s and 1960s showed that
A) trichromatic theory is correct and opponent-process theory is incorrect.
B) opponent-process theory is correct and trichromatic theory is incorrect.
C) both trichromatic and opponent-process theories are fundamentally correct.
D) neither trichromatic theory nor opponent-process theory is fundamentally correct.
C) both trichromatic and opponent-process theories are fundamentally correct.
Research has shown that neurons in the primary visual cortex are sensitive to the \_\_\_\_\_\_ of visual stimuli. A) orientation B) colour C) rate of movement D) All of these aspects.
D) All of these aspects.
Treisman demonstrated that the ability to detect a slanted line in an array of vertical lines involved automatic, parallel processing by showing that
A) the speed of detection was not affected by the number of vertical lines in the array.
B) the speed of detection was affected by the number of vertical lines in the array.
C) people could identify several slanted lines in an array as quickly as just one.
D) it took longer for people to identify several slanted lines in an array than to identify just one.
A) the speed of detection was not affected by the number of vertical lines in the array. ?
According to Treisman's (1988) theory on visual perception, identification of a single unique feature can be accomplished with \_\_\_\_\_\_ processing, but identification of a unique conjoining of two or more features requires \_\_\_\_\_ processing. A) parallel; serial B) serial; parallel C) serial; proximity D) parallel; proximity
A) parallel; serial
