Most physiologists deal with reduction. Phenomena are explained in terms of simpler phenomena. For example, the movement of a muscle is explained in terms of changes in the membrane of muscle cells, entry of particular chemicals, and interactions between protein molecules within these cells. A molecular biologist would "explain" these events in terms of forces that bind various molecules together and cause various parts of these molecules to be attracted to one another.
Like other scientists, physiological psychologists believe that all natural phenomena--including human behavior---are subject to the laws of physics. Thus, the laws of behavior. can be reduced to descriptions of physiological processes.
How does one study the physiology of behavior? Physiological psychologists cannot simply be reductionists. It is not enough to observe behaviors and correlate them with physiological events that occur at the same time. Identical behaviors, under different conditions, may occur for different reasons, and thus be initiated by different physiological mechanisms. This means that we must understand "psychologically" why a particular behavior. occurs before we can understand what physiological events made it occur.
What does the passage mainly discuss?
A.The difference between "scientific" and "unscientific" explanations.
B.The difference between human and animal behavior.
C.How fear would be explained by the psychologist, physiologist, and molecular biologist.
D.How scientists differ in their approaches to explaining natural phenomena.
In this country, there is far more to apprehend from Congress, than from the executive, as is seen in the following reasons: —Congress is composed of many, while the executive is one, bodies of men notoriously acting with less personal responsibilities than individuals; congress has power to enact laws, which it becomes the duty of the executive to see enforced, and the rally legislative authority of a country is always its greatest authority; from the decisions and constructions of the executive, the citizen can always appeal to the courts for protection, but no appeal can lie from the acts of congress, except on the grounds of unconstitutionality, the executive has direct personal responsibilities under the laws of the land, for any abuses of his authority, but the member of congress unless guilty of open corruption, is almost beyond personal liabilities.
It follows that the legislature of this country, by the intention of the constitution, wields the highest authority under the least responsibility, and that it is the power most to be distrusted. Still, all who possess trusts, are to be diligently watched, for there is no protection against abuses without responsibility, nor any real responsibility, without vigilance.
Political partisans, who are too apt to mistake the impulses of their own hostilities and friendships for truths, have laid down many false principles on the subject of the duties of the executive. When a law is passed, it goes to the executive for execution, through the executive agents, and, at need to the courts for interpretation. It would seem that there is no discretion vested in the executive concerning the constitutionality of a law. If he distrusts the constitutionality of any law, he can set forth his objections by resorting to the veto; but it is clearly the intention of the system that the whole legislative power, in the last resort, shall abide in congress, while it is necessary to the regular action of the government, that none of its agents, but those who are especially appointed for that purpose, shall pretend to interpret the constitution, in practice. The citizen is differently situated. If he conceives himself oppressed by an unconstitutional law, it is his inalienable privilege to raise the question before the courts, where a final interpretation can be had. By this interpretation the executive and all his agents are equally bound to abide. This obligation arises from the necessity of things, as well as from the nature of the institutions. There must be somewhere a power to decide on the constitutionality of laws, and this power is vested in the supreme court of the United States, on final appeal.
The author's purpose in writing this passage is to indicate ______.
A.the difference between kings and presidents
B.the power of the Supreme Court
C.the limitations of the presidency
D.the irresponsibility of Congress
In only two decades Asian Americans have become the fastest-growing U. S. minority (少数民族 ). As their children began moving up through the nation's schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation's best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian--American students who began their educations abroad arrived in the U. S. , with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.
Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. Ah effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education.
Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial (种族的) image. Many can remember when Chinese, Japanese and Filipino immigrants (移民) were the victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.
While making tremendous achievements at college, Asian-American students ______.
A.feel they are mistreated because of limited knowledge of English
B.are afraid that their academic successes bear a strong Asian character
C.still worry about unfair treatment in society
D.generally feel it a shame to have to depend on their parents
