CHAPTER SIX 1. What determines a person’s response towards sensory deprivation and what has research said about how people respond towards sensory deprivation? (pg 190) Responses to sensory deprivation are linked to how the person is interpreting the experience and what their expectations are for the experience. In initial studies of sensory deprivation, male volunteers reported feeling edgy after the first few hours. Some men actually left the study the first day because of the disorienting affects of sensory deprivation. Those that stayed longer became confused, restless, and grouchy and some reported have hallucinations. However, these testing methods were later found questionable and more recent studies have found less disorienting affects. Some people even enjoy some limited time periods of sensory deprivation. 2. Describe how the eye differs from a camera? (pg 192) The eye differs from a camera in that it is not a passive recorder of information. Instead of simply registering spots of light and dark like that of a camera, neurons in our eyes construct a picture of the world by detecting and processing that information and its meaningful features. The eye uses a complex process that differs greatly from that of a camera. 3. Explain why people continue to feel "limbs" once they have been amputated? (pg 209210) According to a revision of the gate-control theory, the brain is capable of generating pain on its own. This pain known as “phantom pain” may arise from a variety of reasons. A lack of sensory stimulation from the missing limb or attempts to move the limb may cause this phenomenon. There is also evidence that brain areas involved with the missing limb may continue to function even after its removal. 4. Can "subliminal perception" tapes help you lose weight or reduce your stress? Explain your answer. (pg 215-216) No, subliminal perception tapes have not found to be effective in countless studies of this question. Placebo tapes, tapes that do not contain any subliminal messages but participants think they do, are just as effective as actual tapes with subliminal perception. To make a change or quit something in your life, watching tapes will not make an effective change, you must work at it the old fashion way with hard work. 5. Explain why most psychologists are skeptical about ESP? (pg 216-217) Many psychologists are skeptical about ESP because most of the evidence for it comes from anecdotal accounts and people are not always accurate about their own experiences. When studies have been shown to support ESP, the experiment had been poorly constructed with many flaws. After lengthy studies, the National Research Council concluded that there is no such thing as para-psychological phenomena.

CHAPTER SEVEN 1. Explain why logic can’t solve all of our problems? (pg. 231) Logic cannot solve all of life’s problems due to informal reasoning problems. Informal reasoning problems are problems that do not have a single, concrete solution. Instead these problems may have several competing solutions
