1. Describe the way in which the trichromatic and the opponent process theory of color vision work. How can they both be correct? Include diagrams. Note: For opponent process, you only need to draw 1 set of all of the different receptive fields and 1 version of how you are able to perceive color using this system from the ones I presented in class.
2. What is our velocity threshold and what factors influence it? Give 3 detailed examples of how biological motion can help with perception (what can we detect just through motion). How do we perceive biological motion (using the corollary discharge theory)?
3. What are the motion illusions (name and describe)? How do we get these experiences?
4. What are the pictorial depth cues? Give an example of each.
5. What are the movement depth cues? What are the oculomotor cues? How do they work (include max. distances)?
6. What is binocular disparity? How are we able to determine depth by using this? Make sure to define disparity, horopter, crossed and uncrossed.
7. Define color constancy, lightness constancy, and size constancy. Give both real life and experimental examples that demonstrates each of these. What may be the explanation for these constancies?
8. What is sound? How does it travel? How does the medium it is traveling through affect the sound wave? What happens to it as it travels? How do the various physical components of the sound wave impact our perception of sound?
9. Draw the complete structure of the outer to inner ear (including inside the cochlea) and describe the contributions each section makes to auditory perception.
10. What are the different types of auditory impairments (both conductive and sensorineural)? What causes these problems?
11. What are the characteristics of the inner and outer hair cells? How are they similar to the receptors of the eye? What is the efferent pathway for and how is it related to otoacoustic emissions?
12. Discuss place (tuning curves) and frequency (volley principle and phase locking) theory. How can they both be correct?
13. How are we able to localize sound both binaurally and monaurally?
14. What is the pathway for sound comprehension and localization in the brain? Make sure you indicate what each section does (afferent).
15. How
is loudness calculated? What and where (on the body) is resonance? How does it
affect loudness? How is pitch related to loudness in terms of the equal
loudness contour (draw graph)?
16. Explain
how surround sound works. Also explain how architectural acoustics and related
factors influence how music sounds in concert halls.
