Describe the difference between bottom-up processing and top-down processing. Provide an example for each type of processing. Answer: Students’ answers will vary. In bottom-up processing, sensory receptors register information about the external environment and send it up to the brain for interpretation. Bottom-up processing means taking in information and trying to make sense of it. In contrast, top-down processing starts with cognitive processing in the brain. Top-down processing begins with some sense of what is happening (the product of experiences) and applies that framework to incoming information from the world. One way to understand the difference between bottom-up and top-down processing is to think about how individuals experience a song they never heard before versus that same song when they have heard it many times. The first time they hear the song, they listen carefully to get a “feel” for it; that is bottom-up processing: taking the incoming information of the music and relying on that external experience. Now, once they have a good feel for the song, they listen to it in a different way. They have expectations, and know what comes next. That is top-down processing. They might even sing along with the song when it comes on the radio or at a club. 152. Describe the phenomenon of phantom limb pain. Answer: Phantom limb pain is an example of confused senses. Among individuals who have lost an arm or a leg, as many as 95 percent of them report alarming and puzzling pain in the amputated limb. Although the limb that contains the sensory receptors is gone, the areas of the brain and nervous system that received information from those receptors are still there, causing confusion. 153. Explain the main difference between absolute and difference thresholds. Answer: The main difference between absolute and difference thresholds is that investigation of the absolute threshold involves the presence or absence of a stimulus, while investigation of the difference threshold involves the amount of change in a known stimulus. 154. When Bill started working in his new office, he found the noise of the air purifier in his room distracting and felt it interfered with his ability to concentrate. After a week or so, the noise stopped bothering him, even though it was still present. Explain the concept that is most likely responsible for Bill’s reaction to the noise after a week. Answer: Sensory adaptation explains Bill’s reaction to the noise after a week. Sensory adaptation is defined as a change in the responsiveness of the sensory system based on the average level of surrounding stimulation. 155. Explain the functions of rods and cones in the context of the visual system. Answer: • Rods are the receptors in the retina that are sensitive to light, but they are not very useful for color vision. Rods function well under low illumination. • Cones are the receptors that are used for color perception. Like rods, cones are light-sensitive. However, they require a larger amount of light to respond than the rods do, so they operate best in daylight or under high illumination. • Rods are found almost everywhere on the retina except in the fovea. Rods give human beings the ability to detect fainter spots of light on the peripheral retina than at the fovea. If a person wants to see a very faint star, he or she should gaze slightly away from it, to allow the rods to do their work. • The rods and cones at the back of the retina convert light into electrochemical impulses. 156. Describe the main principles of the trichromatic theory of color vision. Answer: The trichromatic theory of color vision states that color perception is produced by three types of cone receptors in the retina that are particularly sensitive to different, but overlapping, ranges of wavelengths. The theory is based on experiments showing that a person with normal vision can match any color in the spectrum by combining three other wavelengths. According to this theory, if the combination of any three wavelengths of different intensities is indistinguishable from any single pure wavelength, the visual system must base its perception of color on the relative responses of three receptor systems—cones sensitive to red, blue, and green. 157. Explain how two-dimensional images on the retina are perceived as three-dimensional objects. Answer: Individuals use cues from the environment to perceive objects three-dimensionally. Binocular cues are depth cues that depend on the combination of the images in the left and right eyes. The image from each eye is slightly different because the eyes are in slightly different positions. The brain uses this “disparity” to determine depth. Additionally, individuals use monocular cues (or depth cues) such as familiar size, height in the field of view, linear perspective, overlap, shading, and texture gradient. 158. In the context of the visual system, describe the three aspects of perceptual constancy. Answer: Retinal images change constantly. Yet even though the stimuli that fall on human retinas change as people move closer to or farther away from objects, or as they look at objects from different orientations and in light or dark settings, their perception of them remains stable. Perceptual constancy is the recognition that objects are constant and unchanging even though sensory input about them is changing. There are three types of perceptual constancy—size constancy, shape constancy, and color constancy—as follows: • Size constancy allows human beings to understand that even though the images on the retina are changing, the size of an object remains constant. • Shape constancy allows human beings to understand that even though from different angles an object may look different; it retains its natural shape. • Color constancy allows human beings to understand that even when a shadow falls on the page they are reading, they know that the color of the page remains the same. 159. Describe the structure and functions of the middle ear. Answer: The middle ear channels sound waves to the inner ear. It consists of the eardrum, hammer, anvil, and stirrup. The eardrum or tympanic membrane separates the outer ear from the middle ear and vibrates in response to sound. It is the first structure that sound touches in the middle ear. The hammer, anvil, and stirrup are an intricately connected chain of the three smallest bones in the human body. When they vibrate, they transmit sound waves to the fluid-filled inner ear. The muscles that operate these tiny bones take the vibration of the eardrum and transmit it to the oval window, the opening of the inner ear. 160. In the context of the auditory system, what is a cochlear implant? Answer: Cochlear implants are devices that were specifically developed to replace damaged hair cells. A cochlear implant is a small electronic device that is surgically implanted in the ear and head. It allows deaf or profoundly hard-of-hearing individuals to detect sound. The implant works by using electronic impulses to directly stimulate whatever working auditory nerves the recipient has in his or her cochlea. 161. Explain the frequency theory of hearing. What is one limitation of the frequency theory? Answer: Frequency theory states that the perception of a sound’s frequency depends on how often the auditory nerve fires. According to this theory, higher-frequency sounds cause the auditory nerve to fire more often than do lower-frequency sounds. One limitation of frequency theory, however, is that a single neuron has a maximum firing rate of about 1,000 times per second. Therefore, frequency theory does not apply to tones with frequencies that would require a neuron to fire more rapidly. 162. Why is the sound reaching one ear more intense than that reaching the other ear? What is this phenomenon known as? Answer: The sound reaching one ear is more intense than the sound reaching the other ear for two reasons: (1) It has traveled less distance, and (2) the other ear is in what is called the sound shadow of the listener’s head, which provides a barrier that reduces the sound’s intensity. This phenomenon is known as sound localization. 163. Describe the fast pathway that transmits pain messages to the brain. Answer: In the fast pathway, fibers connect directly with the thalamus and then to the motor and sensory areas of the cerebral cortex. This pathway transmits information about sharp, localized pain, as when a person cuts his or her skin. The fast pathway may serve as a warning system, providing immediate information about an injury—it takes less than a second for the information in this pathway to reach the cerebral cortex. 164. What are the two distinct systems that form the chemical senses? Answer: Taste and smell are the two distinct systems that form the chemical senses. 165. What is the most dangerous threat with respect to the sense of hearing? Answer: With respect to the sense of hearing, perhaps the most dangerous threat comes from loud noise. A special concern is hearing damage that can be caused by loud noise during leisure activities. True/False Questions 166. Katie smells a flower.
