DQ 1 -
Part A -
1. What is the connection between hair cell damage and hearing loss? Exposure to occupational or leisure noise and hearing loss?
2. Describe the procedures for measuring auditory thresholds in infants. How does the infant's audibility curve compare to the adult curve?
Part B -
1. What is the auditory scene analysis, and why is it a "problem" for the auditory system?
2. What is the difference between the rhythmic pattern and metrical structure?
3. Describe the ways the vision dominates hearing, hearing dominates vision, and how sounds provides information that influences what we see.
Part C -
1. How does experience-dependent plasticity contribute to a child's development of the ability to perceive phonemes during the first year of life?
2. What is the evidence that meaning can influence word perception?
3. What mechanism helps us perceive breaks between words?
4. How do speaker characteristics influence speech perception?
DQ 2 -
Part A -
1. What objects are involved in identifying objects by haptic exploration?
2. What are some of the physiological processes involved in recognizing objects by touch?
3. Describe the three types of pain.
4. What is the gate control mode? Be sure to understand the roles of nociceptors, mechanoreceptors, and central control.
Part B -
1. What are the main structures in the olfactory system past the olfactory bulb?
2. What is flavor perception? Describe how taste and olfaction meet in the mouth and nose then later in the nervous system.
3. What is the Proust Effect? Is there any evidence for it?
4. How has formation of the representation of odor objects in the cortex been described as being caused by experience? How is this similar to the process of forming memories?
