Hi, I would like help studying for an upcoming test. Please answer my questions that I have for you here.

What is the distal stimulus in hearing? Is it the change in sound pressure level at the eardrum, the event that causes sound waves to be transmitted through air, the vibrations in the fluid inside of the cochlea, or the wavelike movements of the basilar membrane?

According to the place theory of pitch, where on the basilar membrane will high-frequency tones cause the greatest amount of vibration to occur? Is it the portion closest to the oval window, in the portion farthest from the oval window, in the middle of the membrane, or in the portion without hair cells?

Why are we unable to see colors in very dim light? Is it because the receptors for color are not sensitive to dim light, lateral inhibition is activated in very dim light, opponent processes cannot operate at low levels of light, or all three?

What does the world look like to people who suffer from the most common type of color blindness? Do they see only shades of gray/ only grays, blues, and yellows/ only grays, reds, and greens/ or only grays, blues, and greens?

What happens when wiring errors are made during brain development? Is it that neurons compete with each other, some neurons are given a signal to die, incorrect and redundant corrections are changed, or all 3?
