Philosophers, religious leaders, the research conducted by psychologists involves, 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.

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.

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. As an example, a study conducted by PsychMed on rates of remission for methamphetamine addiction showing that people who gave up tobacco and methamphetamine had higher rates of remission than those who quit methamphetamine alone, has helped us to advise on issues around co-substance use.

Figure 4. Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. While behavior is observable, the mind is not.

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.

Research methods in psychology are systematic procedures used to observe, describe, predict, and explain behavior and mental processes. They include experiments, surveys, case studies, and naturalistic observations, ensuring data collection is objective and reliable to understand and explain psychological phenomena. Hypotheses are statements about the prediction of the results, that can be verified or disproved by some investigation. There are four types of hypotheses :. All research has an alternative hypothesis either a one-tailed or two-tailed and a corresponding null hypothesis. Once the research is conducted and results are found, psychologists must accept one hypothesis and reject the other. So, if a difference is found, the Psychologist would accept the alternative hypothesis and reject the null.

Figure 1. The researcher who more often than not is really a small group of researchers formulates a research question, conducts a study designed to answer the question, analyzes the resulting data, draws conclusions about the answer to the question, and publishes the results so that they become part of the research literature. Because the research literature is one of the primary sources of new research questions, this process can be thought of as a cycle. New research leads to new questions, which lead to new research, and so on. But even in these cases, the researcher would start by checking the research literature to see if the question had already been answered and to refine it based on what previous research had already found. The research by Mehl and his colleagues is described nicely by this model. When they checked the research literature, however, they found that this question had not been adequately addressed in scientific studies. They conducted a careful empirical study, analyzed the results finding very little difference between women and men , and published their work so that it became part of the research literature. The publication of their article is not the end of the story, however, because their work suggests many new questions about the reliability of the result, about potential cultural differences, etc.

An examination of post attitudes towards Arab Americans. Why are we so apt to believe in illusory correlations like this? They argue that it would be impossible to study topics such as altruism, aggression, obedience, and stereotyping without using deception because if participants were informed ahead of time what the study involved, this knowledge would certainly change their behaviour. In these cases, people are observed while engaging in set, specific tasks. If someone is crying, we can see behavior. Paragraph on correlation. To make sure that any effects on mood are due to the drug and not due to expectations, the control group receives a placebo in this case a sugar pill. The findings of psychological research can help us navigate issues like this. Conceptual variables are abstract ideas that form the basis of research hypotheses. How do researchers obtain accurate information when people tend to hide their natural behavior? The temptation to make erroneous cause-and-effect statements based on correlational research is not the only way we tend to misinterpret data. All documentation will be kept strictly confidential. 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.

Despite the differences in their interests, areas of study, and approaches, all psychologists have one thing in common: They rely on scientific methods.

Research reports describing scientific studies are published in scientific journals so that other scientists and laypersons may review the empirical findings. Journal of Personality and Social Psychology. When should and should not animals be used? For example, the evidence people leave behind as they traverse their physical environment is unobtrusive. In summary, because we cannot test all of the fourth graders in a city, we want to find a group of about that reflects the composition of that city. By being blind to which child is in which group, we protect against those biases. Peer reviewers look for a strong rationale for the research being described, a clear description of how the research was conducted, and evidence that the research was conducted in an ethical manner. Often longitudinal studies are employed when researching various diseases in an effort to understand particular risk factors. Statistical Thinking. Instead of observing a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of year-old individuals and compare them to a group of year-old individuals and a group of year-old individuals. Erol A. An example of a descriptive device used in psychological research is the diary , which is used to record observations. Future testing may disprove the hypothesis. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. Getting 14 or more heads in 16 tosses is about as likely as tossing a coin and getting 9 heads in a row.
