The scientific method is a convenient way of making observations, collecting data, making decisions, and interpreting outcomes. Psychologists from all around the world use the scientific method to help manage their research. Psychologists make use of the scientific method because they need to be able to describe, explain, and predict mental processes or behaviors. Within the scientific method are hypotheses, variables, results, and conclusions. A hypothesis is a prediction that will be tested in an experiment; researchers and psychologists always start off with this. An example of a hypothesis is if a student skips class on Monday, Wednesday, and Friday, their grades will drop down. This example can be falsifiable because the student’s skipping …show more content…
There are two significant classifications of the observational method such as naturalistic observation and laboratory observation. Naturalistic observation involves observing objects in their natural habitat; this type of research is often used in a situation where doing lab research is expensive or would disorderly affect the subject’s behavior (Cherry, n.d.). In a laboratory observation, study subjects are brought into a laboratory setting to be researched on; laboratory observations can also give greater control over the subjects (Moyer, 2014). Laboratory observations allow psychologists to gather data more efficiently than they are able to do in a natural …show more content…
This method relies on controlled methods, random assignment and the manipulation of variables to test a hypothesis (Cherry, n.d.). Psychologists are able to manipulate the independent variable and observe the dependent variable. The independent variable is a component in the experimental method that can be changed or manipulated (Cherry, n.d.). The dependent variable can be affected by changes in the independent variable; it’s the variable that is being measured in the experiment. The dependent variable relies on the independent variable. The experimental method also include psychologists splitting subjects up into groups known as experimental group and control group; both groups receive the same treatment , but one gets something different. Psychologists manipulate one part of the experiment in the experimental group, but do not manipulate it in the control group; the variable that becomes manipulated is the independent variable. Experimental group subjects are exposed to one version of the treatment; whereas the control group serves to compare and contrast the effect of the

Research, Statistics, and Psychology

...Statistics, and Psychology Psychology is the scientific investigation of mental processes and behavior (Kowalski & Westen, 2007, p. 3). During the late 19th century, psychology became an actual science because of the fascination of human behavior. Psychologists use observation to measure human behavior better to understand mental and biological processes, motives, and personality traits. Human behavior may be understood through applied and academic science (Psychology Majors, 2011). Based on this, research using the scientific method is necessary for statistical psychology. Early research and use of scientific method in psychology included the works of Edward Titchener. Titchener used structuralism to explore aspects of the mind. Research through this method focused on introspection, or individual conscious experience. Titchener used a table method similar to a chemistry periodic table to study human behavior. Titchener believed experimentation was the only scientific method to use for the study psychology (Northern Illinois University, 2003). A paradigm in psychology is a set of theoretical assertions that provide a model, abstract picture, or object of study (Kowalski & Westen, 2007, p. 11). A paradigm is a set of shared metaphors that compare any object of study through investigation. Many modern psychologists use innovative approaches to study human behavior to support traditional methods of psychology through use of research using the scientific method. According...

Research Statistics and Psychology

...Research, Statistics, and Psychology To understand thoroughly something a person must understand its background and conduct research. According to Bing Dictionary (2012), research is an organized way to study something; that can include an investigation to uncover facts, to create a theory or correct a previous one, or to make a plan based upon the discovered facts. A person cannot conduct or make connections in research without the use of statistics. Statistics can be just about any compilation of information on any subject in use with performance, time management, effectiveness, budgeting, and many more. Both research and statistics are important components in psychology. This paper will discuss the role of research and statistics within psychology. Examining what research and the scientific method are, comparing and contrasting the characteristics of primary and secondary data, and explaining the role of statistics within research.

...friend who thinks psychology is all that stuff they see from people like Dr. Phil and others in the media. Based on what you have read in chapter one, how would you convince your friend that psychology is a science? First of all, I will tell you about science. Basically, science refers to a system of getting something (esp. knowledge) based what they call a scientific methods. With scientific method, we can prevent possible biases from leading to faulty observation. Based what I’m studying until now, science allows for precise and careful measurement. Isaac Newton in his book “Philosophiae Naturalis Principia Mathematica” , says that scientific method refers to the body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. It is based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning. So, we can also say that a scientific method consist of the data that we get from the observation and experimentation. The data that we get from the scientific method also must be tested whether it is appropriate with hypotheses or not. Therefore, if we get a conclusion through the steps from scientific method, we said it is science. Now, move on to the Psychology. You said that psychology is all that stuff you see from people like Dr. Phil and others in the media. Let me tell you how Dr. Phil deals with psychology.

Like biological psychology, this branch also seeks knowledge that potentially unlocks wonders of the mind. However, cognitive psychology focuses on the mental processes from an internal source not physically apparent. Whereas technology provides efficient methods for which to scan a brain and the activity therein, studying the mind is still yet to uncover mysteries behind thought. Studying the mind involves observation of behavior and of the environment but determining reason for thought in general is still out of reach. Inabilities to determine unobtainable conclusions do not slow the pursuit of knowledge, for the study of conscious thought continues. This paper includes an understanding of what cognitive psychology, as well as information regarding four essential milestones contributing to the development of cognitive psychology. In addition, this paper also focuses on the importance of behavioral observation. Comprehending Cognitive Psychology Cognitive psychology currently focuses on three main human characteristics. The first characteristic is the ability to perceive.

Research, Statistics, and Psychology

...Research, Statistics, and Psychology Research and statistics employ such meaningful roles in psychology whereas without both psychology may not exist. In psychology the importance of research is to help understand human beings and behaviors, but without research questions concerning human beings and behavior would go unanswered. Thoughts and theories concerning human beings and behaviors would go unanswered as well. Using and relying on the scientific method, psychology uses the research and statistics gathered to prove or disprove thoughts and theories. The importance of statistics in psychology is that they help in determining if research findings are not substantive or substantive. Not only do research and statistics play a part in psychology, the roles of the scientific method, primary data, and secondary data contribute as well. Research and the Scientific Method Research is the collection and evaluation of information or data about a particular subject (Nordquist, 2013). Psychology research is about values, variables, and scores. Values are categories or numbers, variables are characteristics or conditions that can have different values, and scores are a particular individual’s value on a variable (Aron, Aron, & Coups, 2009). Psychological processes confirmed by research to occur outside one’s awareness with several associations between behaviors, and feelings, or situations guiding one’s behavior, either unconsciously or implicitly (Kowalski & Westen, 2011).

...The Philosophical Roots of Modern Psychology Aissa Gulbrandsen November 16, 2013 Psych/310 Professor Sharon Cohen Psychology is a relatively young science, just over a hundred years old. Philosophers over the passing centuries formed various theories based on their observations in human behavior. “At the heart of both philosophy and psychology are questions about the nature of knowledge: Is the world an invention of the human mind? Are some methods of gaining knowledge (e.g., scientific methods) more reliable and rational than others? And can we ultimately justify fundamental beliefs concerning such things as the laws of logic, the existence of other minds (in addition to our own), and the durability of causal relationships?” (Fletcher, 1996). The origins of modern psychology have their roots in philosophy harking back to the beginning with the Greeks, and on to the age of enlightenment and into the 19th century. In the 17th century philosophers like Rene Descartes took their observations about human behavior and tried to explain how the mind and body worked. Descartes created a distinction between mind and body. He posited that the mind was in the pineal gland and the body composed...

Industrial and Organizational Psychology

These pioneers concerning themselves solely upon the industrial side of the profession had interests in placing into work new principles of psychology to improve efficiency in organization, and job performance. Through this beginning, I/O psychology continues to expand and develop into the psychological discipline it is today. A simple definition or practical applications of I/O psychology are the mere pinnacles in understanding the scope of the discipline. Examining the evolution of I/O psychology, in addition to explaining the role of research and statistics in I/O psychology will reveal the foundation upon which the pinnacles rest (Spector, 2008). Evolution of I/O Psychology The credit for the development of I/O psychology lies with Walter Dill and Hugo Münsterberg. Both individuals were professors and experimental psychologists who began applying principles of psychology to organization’s problems. Münsterberg’s interests in employee selection processes brought about the use of psychological testing. His inability to gain acceptability and respect for his theories at Harvard, or...

Foundations of Psychology

...Foundations of Psychology PSY 300 August 8, 2011 Teresa Neal Foundations of Psychology The human being is a complex and sometimes mystifying being. Our actions, behaviors, emotions, mannerisms, and functions are all so complicated and sometimes mystifying. Questioning why we do what we do, act the way we do, behave in a certain manner, or react to a situation, even asking these questions in general is the very reason for the study of Psychology. Psychology is the scientific investigation of mental processes and behavior, and as stated in our book, psychology lies in the intersection of biology and culture [ (Kowalski & Westen, 2009) ]. Throughout the journey of psychology there have been many brilliant and ground breaking scientists and psychologists who’ve laid the foundations for what is studied today. Through these journeys many schools of thought and perspectives have been formed into this foundation which we still use today. It is said that Psychology is between biology and culture, it is meaning that biology covers the central nervous system and within that system are the areas with which control many of our mental processes. Culture has a place on the opposite boarder of psychology because how and where we grew up effects the way we are in regard to our behavior and reactions to situations. While Psychology is said to border biology and culture, it is said to be born from philosophy. When Philosophers started looking for more answers in regard to the nature...

...Annotated Bibliography Benett, Yates (2011) How Social Science Research Methods Might Provide Scientific Evidence for the Existence of God. Retrieved September 11, 2013 from Christian Higher Education The article by Benett can be misleading. The article discusses the how of using social science research for the intended research for the existence of God. The author goes into detail using the scientific method for sociologic research. Yates states “in social science research it is considered scientific to collect data about the world, to build theories to explain the data and to test those theories against further data” (p. 2). Discussing every part of the scientific method, he gives examples for how he might go about with that that part of the method. Yates also discusses different approaches to the research. Phenomenology is discussed as a method for the study and possible explanation, but is left out. Instead the author decides on methodological triangulation because it allows differing methods of data collection regarding a social issue. The reason why this would be the best method as well as its benefits in social research is discussed. Yates also states that using combined research is extremely beneficial. This article will be useful because it demonstrates using the scientific method for sociologic research. It goes in depth giving example for each part of the method.

Statistics and Reseach in Psychology

...Research, Statistics & Psychology Psy 315 April 15, 2013 Research, Statistics & Psychology The role of research and statistics in psychology are key parts for development of the field. Research is studying out the facts and information of a subject/topic to come to an understanding about it. It is done through scientific method, a systematic approach to gathering and “proving” information. Primary and secondary data are two collection methods of resources. Primary data deals directly from the original source whereas secondary data is from a second or third party and is not as reliable. Statistics comes in by expressing results in an understandable, usually visual, way. All these will be discussed herein below. Research Research is an in depth study, with intention of understanding, of, or revision of, facts, theories or laws ("Merriam-Webster", 2013). In turn, research is when one gathers information from numerous sources and learns about the specified / chosen topic until they have a clear knowledge themselves. It’s also used to prove /disprove opinions or hypotheses. Research is most beneficial when done with a systematic approach as it keeps one on track, and organized in their studies. According to Blankenship, there are eight steps to research: identify the problem or questions, review literature, clarify the problem, clearly define terms and concepts, define the population, develop an instrumentation plan, collect data, and analyze the data.
