Please be familiar with the following topics (for details, refer to Denes & Pinson .
To be certain that you understand the concepts of psychophysics described within, ask yourself the following questions (if you understand the concepts, the answers should be clear. If you're in doubt, then your grasp of psychophysics could use some polis hing).
What are the units of the absolute threshold? Can the units be in dB? Can the units be in Hz? Must they be one or the other, or can they be either?
Can the mehtod of limits be used to measure the sensitivity of taste buds?
Does the visual system have an absolute threshold? What units might it be in?
Is the number of DISCRETE (i.e., perceptably different) picthes within the human range of hearing finite or infinite? If finite, could this number be calculated? What information would you need?
Dogs can hear frequencies that humans cannot. How could you explain this in psychophysical terms?
