As information continues to become easier to produce and access, doing research is likely to become more relevant for everybody.

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? Or, could seeing fictional violence actually get aggression out of your system, causing you to be more peaceful? How are children influenced by the media they are exposed to? A psychologist interested in the relationship between behavior and exposure to violent images might ask these very questions. The topic of violence in the media today is contentious. Since ancient times, humans have been concerned about the effects of new technologies on our behaviors and thinking processes.

Philosophers, religious leaders, and politicians, among others, also strive to provide explanations for human behaviour. But psychologists believe that research is the best tool for understanding human beings and their relationships with others. Rather than accepting the claim of a philosopher that people do or do not have free will, a psychologist would collect data to empirically test whether or not people are able to actively control their own behaviour. The statements made by psychologists are empirical, which means they are based on systematic collection and analysis of data. All scientists whether they are physicists, chemists, biologists, sociologists, or psychologists are engaged in the basic processes of collecting data and drawing conclusions about those data. The methods used by scientists have developed over many years and provide a common framework for developing, organizing, and sharing information. The scientific method is the set of assumptions, rules, and procedures scientists use to conduct research. In addition to requiring that science be empirical, the scientific method demands that the procedures used be objective , or free from the personal bias or emotions of the scientist. The scientific method proscribes how scientists collect and analyze data, how they draw conclusions from data, and how they share data with others. These rules increase objectivity by placing data under the scrutiny of other scientists and even the public at large. Because data are reported objectively, other scientists know exactly how the scientist collected and analyzed the data. Most new research is designed to replicate — that is, to repeat, add to, or modify — previous research findings. The scientific method therefore results in an accumulation of scientific knowledge through the reporting of research and the addition to and modification of these reported findings by other scientists. One goal of research is to organize information into meaningful statements that can be applied in many situations.

Simply put, reliability refers to the consistency of a measure. Dominus, S.

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.

Scientific research is a critical tool for successfully navigating our complex world. While many of us feel confident in our abilities to decipher and interact with the world around us, history is filled with examples of how very wrong we can be when we fail to recognize the need for evidence in supporting claims. It is through systematic scientific research that we divest ourselves of our preconceived notions and superstitions and gain an objective understanding of ourselves and our world. The goal of all scientists is to better understand the world around them. Psychologists focus their attention on understanding behavior, as well as the cognitive mental and physiological body processes that underlie behavior.

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.

We will discuss the basics, pros and cons of each! Deception occurs whenever research participants are not completely and fully informed about the nature of the research project before participating in it. The experimenter treats the participant with concern and respect and attempts to make the research experience a pleasant and informative one. This is a clear majority, but we again need to consider variation due to random sampling. Learn more. The Scientific Process. All of this allows psychologists to gain a stronger understanding of how the human mind works. Statistical Thinking. The most direct ethical concern of the scientist is to prevent harm to the research participants. The conceptual variables are represented in circles at the top of the figure Psychotherapy and anxiety , and the measured variables are represented in squares at the bottom number of hours the patient has spent in psychotherapy and anxiety concerns as reported by the patient. Obviously, when they focus their attention on a very small number of people, they can gain a tremendous amount of insight into those cases. For one, these studies require an incredible time investment by the researcher and research participants. We expect that the dependent variable will change as a function of the independent variable. Main articles: Human subject research and Animal testing.

Kendra Cherry, MS, is a psychosocial rehabilitation specialist, psychology educator, and author of the "Everything Psychology Book.

If you do choose to participate, you are free to withdraw at any time without prejudice. Scientific knowledge is advanced through a process known as the scientific method. Figure 27 shows the results from 1, such hypothetical random assignments for these scores. Remember that a good scientific hypothesis is falsifiable, or capable of being shown to be incorrect. CC licensed content, Original. Theories may develop later to explain these observations [17] or classify associated phenomena. However, the principle of inconspicuous observation is violated as reality stars are followed by camera crews and are interviewed on camera for personal confessionals. August Learn how and when to remove this template message. All data must be accounted for, even if they invalidate the hypothesis. Reliability and Validity.
