Vision

The stimulus input for vision is:

• color

• electromagnetic energy

• sound waves

• photoreceptors

Which part of a light wave determines brightness?

• wavelength

• amplitude (wave height)

• complexity (purity of the wave)

Which part of the eye regulates the size of the pupil responding to both light intensity and inner emotional state?

• iris

• lens

• sclera

• retina

What is the white part of the eye called?

• cornea

• lens

• iris

• sclera

The photoreceptors

• include the rods and cones

• are responsible for transduction

• are contained within the retina

• all of the responses are true

The rods synapse with

• the cones

• the bipolar cells

• the ganglion cells

• the optic nerve

Which is the correct order for the visual pathway?

• optic nerve - thalamus - occipital lobe

• retina - occipital lobe - optic chiasm

• rods and cones - optic chiasm - temporal lobe

• ganglion cells - rods and cones - thalamus

Which theory explains that we see colors because a particular cone fires for a particular wavelength?

• Young Helmholtz

• Opponent Processing

• 2 Stage Color Processing

Hubel and Wiesel explained that particular nerve cells fire when detecting a line, or edge, or angle. This is called:

• trichromatic color theory

• parallel processing

• specialized pathways

• feature detection

The brain divides visual scenes into subdivisions and processes each track separately and simultaneously. This is called:

• feature detection

• consciousness

• parallel processing

• impossible
