_____ 2.The optic chiasm is the point at which the optic nerves from each eye meet. Page: 174

_____ 4.The minimal change in stimulation that is required to detect a difference between two stimuli
is a “just noticeable difference.” Page: 166
_____ 5.You walk through the fragrance area of a department store. According to Weber’s law, you will be unlikely to notice the smell of smoke in the store. Page: 166
_____ 6.You smell a flower. While receptors in your nose register a stimulus, the actual process of recognizing the stimulus as a flower’s fragrance and interpreting it as pleasant is known as perception. Page: 161
_____ 7.Transduction is the process of turning perceptions into sensations. Page: 161
_____ 8.The fan on your air filtering unit runs very quietly. From the next room, you cannot hear the sound. Checking whether it is running or not, you move toward it until you can hear it. The point at which the sound is loudest and clearest to you is the absolute threshold. Page: 164
_____ 9.You are decorating and want to pick fabric and paint colors. You are trying to decide how saturated or pastel you want each color to be. From this chapter, you know that the more white light is added to the single wavelength of a color, the more pure the color is. Page: 172
_____ 10.You are driving in traffic and you look at the traffic signal to see if it is red or green. When light comes into your eye, it first passes first through your eye’s lens. Page: 172
_____ 11.Your friends are wondering what causes the phenomenon of color afterimages, which we all have experienced. You look in your text. The first thing you find is that the trichromatic color theory of vision has a difficult time explaining color afterimages. Page: 176
_____ 12.If you were unable to explain to your friends what causes color afterimages by using the trichromatic color theory of vision, you could consult your text and tell them about opponent-process theory, which should help to explain this phenomenon. Page: 186
_____ 13.Wavelengths are used to measure the frequency of sound waves. Page: 186
_____ 14.When you hear any sound, your eardrum vibrates. These vibrations are then transferred to the inner ear by the hammer, anvil, and stirrup; these three bones are all located in the middle ear. Page: 188
_____ 15.You attend a music concert. When you hear the pitch of a voice or instrument, this is your perception of frequency, and when you hear the loudness of the music, this is your perception of its amplitude.
