Which statement about color perception theory is true?
The mechanisms involved in opponent-process theory take place earlier in the perceptual process than those involved in trichromatic theory.
The processes proposed by both trichromatic theory and opponent-process theory take place in the primary visual cortex.
Trichromatic theory and opponent-process theory are both strongly supported by behavioral and physiological evidence.
Recently, trichromatic theory has overtaken opponent-process theory as the best explanation of color and hue perception.
Blindsight is the condition in which someone with damage in the primary visual cortex reports that they cannot see an object, but can usually guess what that object is. This means that some visual representation must reach the frontal speech area. What non-thalamic pathway might do that?
Question 8 options:
A)
The pathway through the suprachiasmatic nucleus
B)
The dorsal visual pathway
C)
The pathway through the superior colliculus
D)
The magnocelluar or M pathway
A pituitary tumor can cause perceptual losses in the lateral visual field. The pituitary gland is located directly inferior to the hypothalamus. Why would this happen?

- Claude Monet was an artist who was known for his impressionist paintings. Later in life, the choices of colors in his paintings changed. These color choices were the result of a visual disorder. What is the visual disorder and why did it affect his choice of colors?arrow_forwardUnilateral Cerebral strokes can cause deficits in motor control, somatic sensation and vision. However, they do not cause deficits in hearing. The explanation for this is: Auditory information does not reach the cortex Auditory information only goes to one hemisphere. Auditory information goes to both hemispheres How are the outer segments of photoreceptors positioned? between bipolar cells and horizontal cells in the outermost layer of the retina in the ganglion cell layer farthest from the pigment epitheliumarrow_forwardWe discussed three principles with regards to the sensory cortex (mechanisms of perception), with one of them being a hierarchical organization. Using the somatosensory system as an example (specifically the exteroceptive part of that system), state each level of the hierarchy with regards to this system, beginning with the one at the lowest level of the hierarchy to the final uppermost level. give the name at each level as it corresponds with this system.arrow_forward
