Have you ever wondered whether the violence you see on television affects your behavior? Are you more likely to behave aggressively in real life after watching people behave violently in dramatic situations on the screen?

Scientists are engaged in explaining and understanding how the world around them works, and they are able to do so by coming up with theories that generate hypotheses that are testable and falsifiable. Theories that stand up to their tests are retained and refined, while those that do not are discarded or modified. In this way, research enables scientists to separate fact from simple opinion. Having good information generated from research aids in making wise decisions both in public policy and in our personal lives. Figure 1.

As information continues to become easier to produce and access, doing research is likely to become more relevant for everybody. In psychology, research plays an essential part in understanding human behaviour, and in the assessment, diagnosis and treatment of psychological disorders. Behaviour can be researched through an array of techniques and study designs, which gives individual studies unique qualities that affect the conclusions that can be drawn from them. This means a single piece of research will rarely provide a comprehensive understanding of a particular problem, and that research needs to be ongoing. In Australia, registration as a psychologist requires university study involving both training in research and conducting research itself. Conducting high-quality research requires critical thinking, rigour, logic, and objectivity, which can be applied to assessing the quality of studies they use to inform their practice. A key area of application for research in psychology is in developing, administering and interpreting psychological assessments. To provide real world meaning of the results, development of psychological assessments requires research in actual populations. The research that is used to develop an assessment has a substantial effect on determining if it is appropriate to use, how the test should be administered, and how the results should be interpreted. Because of this, understanding the research behind an assessment is important in psychological practice. Research is also conducted in psychology to develop treatments for psychological disorders, determine whether they are effective, and use them in clinical practice. As psychologists are required to follow evidence-based practice, treatments used by psychologists have been demonstrated under scientific conditions to produce results. Research into the efficacy of treatments enables psychologists to better understand the variables involved and ensures treatments are applied in the most effective way.

Principles that are so general as to apply to all situations in a given domain of inquiry are known as laws. Experiments are conducted in order to determine cause-and-effect relationships. Use limited data to select content.

Psychological research refers to research that psychologists conduct for systematic study and for analysis of the experiences and behaviors of individuals or groups. Their research can have educational , occupational and clinical applications. Wilhelm Wundt is credited as one of the founders of psychology. He created the first laboratory for psychological research. Psychological research risks harming the subjects of the research. In order to prevent that harm, proposed studies are usually approved by an institutional review board to ensure that the risks to the research subjects are justified by the anticipated benefits.

Despite the differences in their interests, areas of study, and approaches, all psychologists have one thing in common: They rely on scientific methods. Research psychologists use scientific methods to create new knowledge about the causes of behavior, whereas psychologist-practitioners , such as clinical, counseling, industrial-organizational, and school psychologists, use existing research to enhance the everyday life of others. The science of psychology is important for both researchers and practitioners. In a sense all humans are scientists. We all have an interest in asking and answering questions about our world. We want to know why things happen, when and if they are likely to happen again, and how to reproduce or change them. Such knowledge enables us to predict our own behavior and that of others. We may even collect data i. When we perform poorly on an important test, we try to understand what caused our failure to remember or understand the material and what might help us do better the next time. When our good friends Monisha and Charlie break up, despite the fact that they appeared to have a relationship made in heaven, we try to determine what happened.

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it. Some methods rely on observational techniques. Other approaches involve interactions between the researcher and the individuals who are being studied—ranging from a series of simple questions to extensive, in-depth interviews—to well-controlled experiments. Each of these research methods has unique strengths and weaknesses, and each method may only be appropriate for certain types of research questions. For example, studies that rely primarily on observation produce incredible amounts of information, but the ability to apply this information to the larger population is somewhat limited because of small sample sizes.

In order to prevent that harm, proposed studies are usually approved by an institutional review board to ensure that the risks to the research subjects are justified by the anticipated benefits. If we find that watching a violent television program results in more violent behavior than watching a nonviolent program, we can safely say that watching violent television programs causes an increase in the display of violent behavior. The future of animal studies in psychology. There is no question that a relationship exists between ice cream and crime e. Dig Deeper: Ethics and the Tuskegee Syphilis Study Unfortunately, the ethical guidelines that exist for research today were not always applied in the past. The IRB reviews these proposals with the principles mentioned above in mind, and generally, approval from the IRB is required in order for the experiment to proceed. Share Feedback. Applied psychology. Quasi-experiment 's are those that a researcher sets up in a controlled environment, but does not control the independent variable. A participant in the Tuskegee Syphilis Study receives an injection. Psychometrics is a field of study concerned with the theory and technique of psychological measurement.

Science is not just knowledge. It is also a method for obtaining knowledge. Scientific understanding is organized into theories.

Figure 1. Retractions can be initiated by the researcher who led the study, by research collaborators, by the institution that employed the researcher, or by the editorial board of the journal in which the article was originally published. In psychology, research plays an essential part in understanding human behaviour, and in the assessment, diagnosis and treatment of psychological disorders. John Wiley and Sons. Want to participate in a study? Figure 3. The hypothesis is extremely important because it bridges the gap between the realm of ideas and the real world. It seems reasonable to assume that smoking causes cancer, but if we were limited to correlational research , we would be overstepping our bounds by making this assumption. The results, reported in terms of grade levels, are displayed in Figure Deception occurs whenever research participants are not completely and fully informed about the nature of the research project before participating in it.
