What is the opponent process theory quizlet?
The Opponent Process Theory states that there are color receptors present in the visual system that respond to the four pairs of colors. The Trichromatic Theory states that the retina is compromised of three distinct types of cones or color-sensitive photoreceptors.
What does the opponent process theory explain?
The opponent process theory explains how the cones connect to the ganglion cells and how opposing cells are excited or inhibited by certain wavelengths of light. The complementary color theory explains which wavelengths translate to which colors and how these colors are processed in the brain.
Which two Colour theories are supported by evidence in the physiology of the retina?
The dual process theory adopts ideas from both the trichromatic theory and the opponent process theory. The photoreceptors in the retina are trichromatic – with peaks at long (red), medium (green) and short (blue) wavelengths – as predicted by Helmholtz.
Which one of the following is an example of sensory adaptation?
When you first walk through the door, the delicious smell of garlic and tomatoes is almost overwhelming. You sit down to wait for a table, and after a few minutes, the scents begin to dissipate until you barely notice them. This is an example of sensory adaptation.
Which of the following structures is responsible for fine detail and color sensations?
retinal receptor cells that are connected near the center of the retina and that function in daylight or in well-lit conditions. They detect fine detail and give rise to color sensations.
Which of the following statement best describes trichromatic theory and opponent process theory?
Which of the following statements best describes trichromatic theory and opponent-process theory? Research has not supported either theory. Both theories are equally accurate, but they apply to different levels of the nervous system. The opponent-process theory is more accurate than the trichromatic theory.
Which of the following is true about cones in the eye?
Which of the following is true about cones? Expln:Cones are the sensory receptors that respond to color and send visual information of high acuity or visual sharpness. The cones are located primarily in the center of the retina. Rods are more sensitive than cones to light, and they respond only to black and white.
What is the opponent processing theory which cells are turned off by which cells?
opponent-process theory: the theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are “turned on” by green and “turned off” by red; others are turned on by red and off by green.
Where does the opponent process theory take place?
While other theories of color vision explain how color is processed by the eye, opponent-process theory explains how it is processed by the brain. Once information about color is detected by the retina, or the membrane in the back of the eye, that information is sent to an area of the brain called the thalamus.
