Critics say that is not nearly enough compared with other prescribers, such as M.D. psychiatrists or nurse practitioners who have at least six years' medical education and clinical experience. Neither Davison nor most other RxP opponents doubt the efficacy of medications. Their greatest objection is to the notion of turning psychology into a prescribing profession. In a field that has struggled long and hard to prove that mind, mood and behavior can be studied empirically, the past decade, Davison says, has seen "exciting developments" that demonstrate the validity of various psychotherapeutic interventions and the psychosocial-behavioral models on which they are based. "The timing is peculiar to abandon psychological science or to convert it to a medical science," explains Elaine M. Heiby of the University of Hawaii, who chairs a committee of the 1,000-member American Association of Applied and Preventive Psychology that is concerned about the medicalization of psychology. "Making sure that practicing psychologists are giving patients interventions based on the best available psychological science should be the APA's priority," argues Emory University's Scott Lilienfeld, president of the Society for a Science of Clinical Psychology (SSCP). More than any philosophical betrayal of psychology, RxP opponents fear that the movement will undermine the science they love. They believe that if prescriptive authority becomes the norm, biomedical requirements will inevitably seep into the psychology curriculum, at the expense of traditional psychological science and methodology. Lilienfeld feels that many clinical psychologists already receive inadequate training in fundamentals such as research design and evaluation. RxP opponents charge the APA with pushing its prescription-privileges agenda without adequately assessing support for it in the field. The 300-member SSCP is the only group within the APA to have taken a formal stance against prescription privileges. The APA has scheduled 30 minutes at its meeting in August for an RxP debate, but its leadership believes it already has an accurate sense of support for its RxP policy. "Except for this small vocal minority, we have just not gotten a lot of groundswell against this from members," says APA president Philip G. Zimbardo of Stanford University. With prescription privileges now a reality in one state, some RxP opponents concede that it may be too late. This year four states besides New Mexico -- Georgia, Hawaii, Illinois and Tennessee -- have pending legislation for psychologist prescription privileges. Over the past decade, 14 state legislatures have considered such laws. Between 1991 and 1997, a U.S. Department of Defense psychopharmacology demonstration project involving two to four years' training produced 10 military psychologists who can write prescriptions.

Response: "Psycholgy field"

A: yes

You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

Question: "What happens to electrons to make them turn into lightning?"

Response: "Electrons gets discharged"

A: yes

If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

Question: "What is left when the stack shrinks?"

Response: "Water vapor and other gases before being released to the air"

A:
yes
