which of the following is an explanatory hypothesis

What was the primary conclusion of Stanley Milgram's obedience research? ________ is a perspective within psychology that emphasizes the potential for good that is innate to all humans, proposing a hierarchy of human needs in motivating behavior. correlated, but not causal. Explanatory Impotence Explanatory impotence is the opposite of explanatory power. A scientific theory is supported by testable and reproducible data. Clearly an army doctor, then. Cognitive psychology focuses on studying ________. Appetite fails, and the relatives keep water cans beyond reach, despite temperatures well above 100 degrees in the shade. Statistics are used by scientists mainly to determine: Whether differences in results between control and treatment groups is significant and important. To simplify, Halley wondered about the following statement: Newtons account of celestial mechanics is correct and, in particular, applies to the motion of comets. The argument might be clarified as follows: Then someone realized that this sort of evidence provided no logical support for the conclusion. How often do plumbers leave water spraying everywhere rather than turning it offif not at the faucet, then at the main? A Guide to Good Reasoning: Cultivating Intellectual Virtues, Creative Commons Attribution-NonCommercial 4.0 International License, The Total Evidence Condition (1): the Improbability of the Outcome, The Total Evidence Condition (2): the Probability of the Explanation, [If we are well above sea level, then water boils quickly.]. More subtle examples are easy to find. It includes the presumption of causation. The empirical method of study is based on ________. The second part of the total evidence condition for explanatory arguments is this: the probability of the explanation must not be implausibly low and must be higher than that of the leading alternative explanations. b. behavior directed toward the goal of harming a person who is motivated to avoid such treatment e. instrumental-reactive aggression theory, According to more recent research by Anderson and Bushman, aggression ranging from instrumental to reactive should be viewed Nearly half the party died before an April rescue, the survivors cannibalizing the dead. If hes her father, then he will go to great lengths to take care of her. Who was the first person referred to as a psychologist? Far worse than the plumber explanation from Dear Abby, it requires a long list of independently improbable things all to be truealternative ways, for example of accounting for the following: the vast documentation rescued from the German Archives; the elaborate sealed rooms set up for funneling the prisoners to their deaths; the movement of enormous quantities of asphyxiating Xyklon B gas to the death camps; the photographs of mounds of bodies; the vast body of eyewitness testimony by both victims and their murderers; and the otherwise mysterious disappearance from history of millions of Jews. Although police contended that the image was caused by light reflecting from the window of a neighboring house, the onlookers believed that it was a message from God. Ann Arbor News. Which of the following exemplifies the empirical method? c. Express thoughts but not feelings. Your first thought would probably be that this supports the explanation that we are sometimes able to see into the future via our dreams. Meteorites provide yet another example. The correct form for an explanatory argument, assuming that P is the explanation and Q is the observable outcome, is this: The first premise, often implicit, states that the explanation enables you to predict the observable outcomethat it really is an outcome. Why does this fall short of qualifying as an example of the scientific method? Operations Management questions and answers. Another explanation for the sunrise already exists in our own background evidencethat the earth is rotating on its axis. An increase in family income leads to an increase in the percentage of income spent on housing. It includes the presumption of causation. c. Hypotheses usually are relatively narrow in scope; theories have broad explanatory power. Which of the following shows the correct order for a scientific explanation? d. revised frustration-aggression theory Astrology is reliable. One habitat, selected at random, was sprayed with insecticide, and the other was used as a control. Making any judgment about the explanation. Which of the following exemplifies the unconditional positive regard component of client-centered therapy? If Newtons account of celestial mechanics is correct and applies to the motion of comets, then a comet with an orbit similar to the 1530 and 1606 comets will appear in December 1758. This point can be broadened: vague statements, in general, are more likely to be true than precise ones. Recall, from Chapter 13, that larger margins of error make it much more probable that the conclusion of an inductive generalization is true; there is a much greater chance that between 50 percent and 60 percent of the voters favor Jones than there is that exactly 55 percent of them do. Wilson Bryan Key, whose most famous book was titled Subliminal Seduction, has argued that Madison Avenue strategically permeates its advertisements with camouflaged sexual images that are invisible unless you look very hard for them. Unlike the case of Halleys comet, the observable outcomesa blue anchor on his hand, a military carriage, regulation side-whiskers, an air of commandare where the reasoning begins. Step 2. Firefighters doused the flaming Molotov cocktail and then detained the man . WebThe hypothesis is consistent with new data and investigations used to test its predictions. An experiment that makes it possible to determine decisively between alternative hypotheses. He had a maritime tattoo, a military carriage, regulation side-whiskers, and an air of command. When an explanation already exists, the arguer is free to respond in, for example, the case of the student pilots performance, OK, but this outcome is explained both by the efficacy of punishment and by the normal return to the current mean after an aberrant performance. But now it violates the second part of the total evidence condition as well! As a useful standard, apply the surprise test by asking whether the outcome would surprise you (assuming you reserved judgment about whether the explanation were true and whether the outcome had been observed). Is there no other explanation of the outcome that already exists? Singular explanationan explanation that is designed to apply only to a single thing or event. d. Who was the first African American to receive a PhD in psychology in the United States? We make our observations when we can and we fashion our explanations when they occur to us, and the same principles of evaluation apply regardless of which comes first. Psychology is a social science discipline. The argument concludes with the assertion of the explanation. Any performance significantly better or worse than the students current mean level of competence would be largely a matter of chance. An even subtler example can be found in academic discussions of the theory that punishment motivates learning better than does reward. Prepare a cost of production report, using the average cost method. Real estate investment trusts (REITs) experienced a record level of profitability in 2004 Soles An increase in family income leads to an increase in the percentage of income spent on housing. During an episode of wheezing, they found that the vocal cords, which are located in the airway leading to the lungs, formed almost a complete barricade across the passage. Also termed the data, the prediction, or the facts. Suppose I say to you, If he is from Chicago, then he is from Illinoisand he is indeed from Illinois, so he must be from Chicago. You cant be absolutely sure without some wider context, but it normally wouldnt make sense for me to explain someones residency in Illinois by pointing to his residence in Chicago. At any given time, each pilot has achieved a certain level of competencecall it the pilots current mean level of competence. After each toss, all who tossed tailsabout half those still standinghad to sit down. No one would have expected a comet in December 1758 unless they were assuming the Newtonian explanation; such an event would have been extremely improbable. Would it require the world to function in mysterious ways or in ways that differ dramatically from the ways that are well established by science? a. aggressive behavior and media violence. a. with the intent to harm physically. [If competition for food among finches on Galapagos is the main cause of extremes in beak sizes, then there are extremes in beak sizes on Galapagos finches, there is no relevant difference in food from island to island, and in conditions of scarcity the finches with extremes survive best. Step 5. No one can even begin to provide an account of the conceptual framework, of the causal mechanisms, that would make sense of it. . The most common alternative is the term theoretical argumentin which, it is said, a theory is supported by appeal to facts. unintentional aggression. Randomly selected students whom teachers believefalselyto have greater potential end up performing better. Clarify the explanatory argument in each of the following passages. The following are illustrative examples of explanatory power. And, though you may not find the ifthen premise, there are two things you can always expect to find if the argument is explanatory: reference to the explanation, often with a discussion of why it is better than alternative explanations; and reference to the observable outcome, often with a discussion of how unlikely that outcome would otherwise General explanationsNewtonian celestial mechanics, for exampleare intended to apply broadly; Newtons theories explain the motion of all heavenly bodies at all times. unintentional aggression. For example, we can ask about the frequency of singular explanationshow frequently butlers leave their fingerprints on candlesticks or how frequently marines have tattoosbut it isnt helpful, probably not even meaningful, to ask about the frequency with which Newtonian mechanics is true. observation - question - hypotheses - predictions - results of investigation - conclusions Which are true of a hypothesis? . Exploratory research is defined as a research used to investigate a problem which is not clearly defined. It describes why the individual is having problems. But the second letter, using the same observable outcome, offers an alternative explanationnamely, that a plumber visited, left the pipe, then surreptitiously retrieved it. C. An increase in family income leads to an increase in the percentage of income spent on housing. The plumber explanation is burdened with improbabilities: The answer in each case is very infrequently. b. in the quest of some nonaggressive goal. Explanatory arguments typically expand our knowledge by offering a different subject matter in the conclusion. b. in the quest of some nonaggressive goal. I subconsciously wanted the test to succeed, so I tended not to count less severe colds that I otherwise would have counted. Gilbert Harman is associated with the phrase. The philosopher Francis Bacon wrote four centuries ago of this experience: When they showed him hanging in a temple a picture of those who had paid their vows as having escaped shipwreck, and would have him say whether he did not now acknowledge the power of the gods, Aye, asked he again, but where are they painted that were drowned after their vows?. So the scientists are wrong when they reject the paranormal, ancient astronauts, and homeopathic medicine! She must be a good driver, since she usually gets where shes going without running into anybody. B. Reject explanatory arguments that have unfalsifiable explanations; they are in principle unable to satisfy the first part of the total evidence condition. But suppose I offer the alternative explanation that air pressure is highly irregular but that it so happens that barometric pressure nevertheless would be 30 inches at 0 feet, 28.7 inches at 1,300 feet, 28.2 inches at 1,800 feet, 27.2 inches at 2,800 feet, 26.2 inches at 3,800 feet, and 25.2 inches at 4,800 feet. The second premise states that the observable outcome has happenedthat it really has been observed. When people insist that they have no repressed memories, then, Freud considers this to be evidence for the presence of resistance, which is itself evidence for the existence of repression. But it is highly probable, whether my theory is true or false, that the reviews will be good or bad or somewhere in between. . There was no control group with which to compare his patients who received the treatment. Slightly less oxygen means that we get tired a little sooner; slightly worn brakes stop the car a little more slowly; slightly less sunlight means the plant grows a little shorter. WebQuestion: Which of the following is an explanatory hypothesis? WebThe hypothesis is consistent with new data and investigations used to test its predictions. One good way to check for an improbable outcome is to ask this: Is this outcome so vague that it might well be true anyway? applying a set of skills to understand and evaluate information. Then it is an explanatory argument. As with the other argument forms introduced in this text, there are a variety of alternative terms for explanatory arguments, none of which seems to have taken the lead. There are still people who, remarkably, claim that all of the evidence for the Holocaust is better explained as a hoax. This is what happened with Torricellis hypothesis. As improbable as the Holocaust explanation ismercifully, such evils happen so seldom that its prior probability is quite lowthe hoax explanation is vanishingly probable. She claims she has never seen that pipe before and doesnt know how it got there. How does Abbys conclusion fare in the face of this alternative explanation? WebWhich of the following is an explanatory hypothesis? The explanations prior probabilitythat is, its probability prior to judging whether the observable outcome is truemust not be implausibly low and it must be higher than that of the leading alternative explanations. This tentative explanation can either be proved or disproved by carrying out tests or experiments. Average people will harm others if told to do so by an authority figure. Also termed a theory or an explanatory hypothesis. Which of the following is NOT a useful step in resolving peer conflict (especially in teenagers) in a nonviolent way? Without using a calculator, find P100P^{100}P100. I hope this explains it for all hands. Bandura's research showed that children who saw adult models commit violent acts repeated those acts more than children who were not exposed to such aggressive models. b. punching an umpire because he made a bad call, "Good aggression" (playing within the rules with high intensity) is known in sport psychology as, Instrumental aggression is aggression occurring, b. in the quest of some nonaggressive goal, A linebacker intends to hurt and injure any receiver who catches a ball over the middle. Suppose I have heard that vitamin C prevents colds; I dont know whether to believe it but decide its worth looking into. Simplicity contributes to epistemic probability, so ask whether the explanation is sufficiently simple. General explanations are typical of science, though are not restricted to it. Also called a theoretical argument, inference to the best explanation, hypothetico-deductive argument, transcendental argument, or diagnostic argument. Vague outcomes are likely to have a high prior probability and thus are likely to signal that the argument is logically weak. Conduct the experiment over and over again. Concrete, according to the campus architect, was poured whenever the schedule required and the necessary materials were available. With total restriction of fluids, death follows in 24 hours. Empirical knowledge is knowledge that is based on experience and observation. These were huge, precise patterns of bent stalks of wheat, corn, and barley that lent themselves to spectacular aerial photographs. thoughts and their relationship to our experiences and our actions. Instrumental aggression is aggression occurring. Observation of one or only a few instances of a phenomenon. A process of examination and discovery of natural phenomena that involves making observations, constructing hypotheses, testing predictions, experimenting, and drawing conclusions and revising them as necessary. Another contemporary of his, French mathematician and philosopher Blaise Pascal, suspected that Torricelli was right but that a greater altitude was required to prove it. Web16.4 Summary of Chapter Sixteen. This is a dirty trick. Lack suggested that a finch species alone on an island evolved an intermediate beak for eating seeds of various sizes. But this outcome provides no support for the explanation. Suppose the prior probability that the butler did it was .10, likewise for the chambermaid. For a fullerand fascinatingaccount of Halleys reasoning, see Ronald Giere. I instinctively jumped to the teases defense. Practically speaking, however, explanations that do precede their observable outcomes are often logically stronger. a. situational causes Note: See Section 6. As with our other inductive arguments, the total evidence condition for logical success has two parts. And in the larger world, organisms themselves are organized into many levels: populations, communities, and ecosystems within the biosphere. More precisely, the condition is that the prior probability of the observable outcome must be sufficiently low. c. Aggression sometimes facilitates performance and sometimes does not. If your hypothesis is "Echinacea reduces the duration and severity of the symptoms of the common cold," what is your null hypothesis? Could you find out for me which five days that man is on the road? Explanatory arguments are probably the most fundamental and frequently used of all arguments, both in science and in everyday life. Explanatory arguments come in several varieties. The requirement that it be possible to specify some observable outcome of an explanation that could prove it to be false. It is the best understanding that we have of that part of the natural world. a. with the intent to harm physically. This is an example of. For singular explanations, the simplest one normally offers the fewest explanatory entities. Many would argue that both the theory of evolution and creationism are equally probable because, after all, they are both theories. If-clause is compared favorably to alternative explanations. Competition for food among finches on Galapagos causes the extremes in beak sizes. a person's unconscious. I was being more careful about my health because I was engaged in the experiment. (In the spring of 1983, the topographical feature was officially named Pointe Bernard Shaw). No names, please. But that proves my point. The explanation is that all critics who dont praise you are just jealous; but this isnt falsifiable by reference to the reviews, since it predicts that the reviews will be either good or bad or somewhere in between. In another type of distinction, some explanatory arguments are general, given that they have application to a wide range of possible observable outcomes; others are singular, in that they apply only to a specific outcome. . Exploratory research is defined as a research used to investigate a problem which is not clearly defined. c. It must be directed toward a human being. e. modeling, c. an interaction of situations and personal beliefs, The general aggression model proposes that when aggression occurs, it will be Another contemporary of his, French mathematician and philosopher Blaise Pascal, suspected that Torricelli was right but that a greater altitude was required to prove it. After much research, he found that comets with similar orbits had also been observed in 1530 and in 1606. Favor outcomes that would falsify alternative explanations. Functionalist psychologists focus on the function of behavior and ________.
