General Psychology Study Guide T est 2 Ch.4 4.1 Identify the basic principles that apply to all senses. (pg. 126) Transduction – the process by which the nervous system converts an external stimulus, like light or sound, into electrical signals within neurons. (simply put energy sends a signal to the brain) 4.2 Discuss the role of attention and the nature of the binding problem. (pg. 126) Selective intention- allows us to select one channel and turn off the others (or at least turn down their volume) Inattentional blindness- it’s the failure to detect stimuli that are in plain sight when our attention is focused elsewhere. The binding problem is a huge mystery, we perceive an apple however we do not know how our brains bind different aspects and relate it all to the apple. CH. 4 Practice Quiz 1. Proprioceptors tell your body where you are in space an dhelp you move efficiently. They are located in your… Muscles and tendons 2. When you are young and love to go to loud stadiums, live concerts or live next to an airport when you are elderly you may not hear so well. This is due to … noise induced hearing loss 3. People have 3 body senses that work together. Which system do we use for touch and pain? Somatosensory 4. Dogs are on average 100,000 times more sensitive to scents than people. 5. The human ear can detect frequencies ranging from about 20 t0 20,000 Hz, although younger kids can hear higher pitched tones better than adults. 6. Numerous taste buds are contained in the little bumps called papillae on our tongues. 7. In order to see, the eye must be able to perceive visual light, which is a form of electromagnetic energy. 8. The ability of the human brain to attend to many sense modalities at the same time is called parallel processing. 9. If a patient suffers traumatic injury and has his left arm amputates but suddenly complains to feel the missing arm and feels a cramped position. What tool will make him feel better? Mirror Box 10. Which theory addresses signal to noise ratio? Weber’s law 11. The ossicles, the smallest bones in the body are found where? Middle Ear 12. Which of the following is a binocular cue to distance? Convergence 13. Thanks to perceptual constancy we see things as the same objects from different perspectives. 14. The parts of the human eye that are visible from the outside do not include the cornea. 15. This part of the ear is shaped like a spiral with a bony outer portion and an inner cavity filled with a think fluid. Cochlea 16. Brain damage caused by Alzheimer’s disease can damage someone’s sense of smell, which can lead to problems if that person cannot detect a gas leak or spoiled food. 17. While we have specialized nerve endings in the skin that let us feel light touch, deep pressure, and temperature, we also sense tough, temperature, and pain with the much more plentiful free nerve endings. 18. The smallest difference in a stimulus that we can detect, such as the difference between a moderately bright light and a slightly brighter light, is known by the term just noticeable difference. 19. The idea that we pay attention to important stimuli and ignore the unimportant stuff is called the filter theory of attention. 20. Which illusion uses converging lines to make one object appear larger than another that is actually the same size? Ponzo 21. Your neighbor’s garage band is playing loudly into the night. When you hear the sound, you are experiencing vibration, mechanical energy traveling through the air. 22. A psychologist who designs technology that functions better for the people who use it, based on what we know about how the human mind and body work, is working in the field of human factors. 23. When discussing how we perceive low pitched tones, scientists use frequency theory to measure the rate at which neurons fire action, potentials. 24. Figures by Gaetano Kanizsa show how just a hint of three or four corners allows the perception of an entire shape. This phenomenon of filling in missing information about outlines is called subjective contours. 25. When we try to integrate conflicting visual and auditory information, oour brains calculate the most likely sound based in input from both sources, then makes its ‘best guess’ to integrate the two. This is known as the McGurk effect. 26. People called “supertasters”, about 25 percent of people, have more taste buds than the rest of us. 27. The vomeronasal organ doesn’t develop in humans, leading some to believe that people don’t respond to pheromones, but the “zero nerve” may prove that hypothesis wrong. 28. An inability to hear due to ossicles failure is an example of conductive deafness. 29. Your sister tells you that to her the numeral 7 is always green and 4 is red. She is surprised to find that you do not think the same. She has a condition called synesthesia. 30. We perceive the brightness of an object based on the intensity of the light that is reflected to our eyes. 31.Broadbend used dichotic listening when listeners hear different messages in each ear.
