Scientific+Method+and+Research+Design


 * 1) Why do psychologists use scientific method to study human behavior? To overcome the biases.
 * 2) Explain the steps a researcher would go through when using scientific method. Consider your topic, develop a theory, than a hypothesis, than research it, after the research figure out what needs to change in your theory and information. repeat.
 * 3) What is a case study? When would it be appropriate to use? What are the pros and cons? involves a psychologist studying one subject (person) extensively. to study a person who for instance has a mental disorder, pros would be you get to see first hand what they think/do, cons would be you never get a definitive answer just theories and hypothesis. it doesn't offer a good representative sample.
 * 4) What is a survey? When would it be appropriate to use? What are the pros and cons? You look at many people but in less detail. when your studying many people rather than just one. pros you get more information. cons you get less in depth analysis.
 * 5) What is naturalistic observation? When would it be appropriate to use? What are the pros and cons? Watching how animals or people act in their natural environment. To see how a family interacts in their own home. Pro's you get to see what happens first hand. Con's you may not get to see anything at all while your waiting to see.
 * 6) What is laboratory observation? When would it be appropriate to use? What are the pros and cons? studying someone in an environment the researcher has provided. when you can't get an episode maybe in a naturalistic observation study. Pro's you create the environment and see how the person reacts. Con's you may not get any reaction of the study.

Notes



**scientific method**
easy to think we know alot about human behavior, but often times intuition and common sense are wrong.

scientific method basically comes from a guess and check process first find a topic for research, think up an answer, and then conduct to get evidence on weather or not your wrong and this develops different theories and tha cycle continues.

**descriptive designs**
description is important and should be tha first step. "the case study" involves a psychologist studying one person intensely tha purpose is to learn something about human nature for future research second goal is to describe rare phenomena this focuses on someone who has a very important characteristic that is different than others but case study is vary limited because its so specific to an individual its also used to get anecdotes to teach people its limited

"surveys" look at many people but do not go in depth usually asking an opinion or report on ones own behavior surveys are only accurate with a random sample of people first decide a population, then gather random individuals and most importantly people can lie, making that survey inaccurate. also information can change or lack grey area "naturalistic observation" involves studying people or animals in their own environments remain unobtrusive, do not affect their behavior this can be used for many research topics, but can be vague "laboratory observations" people are studied in a controlled environment, decided by that researchers are good example is mirrored glass
