2. Just what is Psychology? Psychology conjures up images of mental disorders and abnormal behavior. Psychologists do study the strange and unusual, but they are interested in the normal and commonplace as well. Just what is psychology? Today psychology is defined as the scientific study of behavior and mental processes.

3. Science or common sense? 1. Memory is more accurate under hypnosis. 2. All people dream during a night of normal sleep. 3. As the number of bystanders at an emergency increases, the time it takes for the victim to get help decreases. 4. Humans do not have a maternal instinct. 5. Older adults tend to express less satisfaction with life in general than younger adults. 6. Eyewitness testimony is often unreliable. 7. Children with high IQs tend to be less able physically than their peers. 8. Creativity and high intelligence do not necessarily go together. 9. When it comes to close personal relationships, opposites attract. 10. The majority of teenagers have good relationships with their parents. Indicate whether each statement is true (T) or false (F).

4. Science or common sense? All of the odd-numbered items are false, and all of the even-numbered items are true. So, common sense, alone, will not take you very far in your study of psychology.

6. How does the scientific method work? The classical approach to solving anything in science starts with a "problem," which through experimentation and prediction, evolves through the "hypothesis" and "theory" stages into a scientific "law." From: Ask GeoMan...

7. The Scientific Method The scientific method consists of the orderly, systematic procedures that researchers follow as they identifya research problem, design a study to investigate the problem, collect and analyze data, draw conclusions, and communicate their findings. (Formal Definition)

8. How does the scientific method work? 1. Wild and Crazy Idea If we assume that all science starts as science fiction, I like this terminology better than just calling it a ”research problem." Getting beyond this involves setting up experiments to verify your idea. Ask GeoMan...

9. How does the scientific method work? 2. Hypothesis If your experimental data fail to support your idea, you'll need to go back to Step 1. If your experiments do support your idea, move on to Step 3. Ask GeoMan...

10. How does the scientific method work? 3. Theory Great, your experiments support your hypothesis, and you are now the proud owner of a theory. Getting beyond this into the law stage requires that you can use your theory to predict the results of additional work, and that your predictions hold. As before, if they don't, return to an earlier step and try again. If your predictions hold consistently, move on to the next stage. Ask GeoMan...

11. How does the scientific method work? 4. Law This is where most discussions of the scientific method end. However, I ( GeoMan) feel two additional steps are almost guaranteed to occur. “scientific law: 1. A natural phenomenon that has been proven to occur invariably whenever certain conditions are met. 2. A formal statement describing such a phenomenon and the conditions under which it occurs.” Also just called a law. http://www.webref.org/geology/s/scientific_law.htm

12. How does the scientific method work? 5. Dogma Laws tend to be supported to such an extent that they almost become dogma. Take gravity for example. When is the last time you dropped a pencil and it floated away. Pretty stupid idea, huh? We are all so sure that gravity is THE LAW that we don't even consider the possibility that there may be exceptions or situations when it breaks down and doesn't work. This leads to the last and final stage:

13. How does the scientific method work? 6. Stagnation This is the death of scientific thought, and should have no place in YOUR thoughts. Question all scientific laws, especially the ones that are the most firmly steeped in dogma. (But don't be stupid about it - throwing yourself off a cliff to test gravity doesn't make much sense!)

Case Studies are frequently used in other disciplines. MBAs frequently use method.
