Critically Discuss the Use of the Scientific Method in Psychology
This essay examines the advantages and disadvantages of using a method primarily for gathering research on human subjects that can be examined for later use. It will give a basic outline of the methods of investigation, their uses and their suitability. I will also look at the scientific method as a whole and examine the criticisms of this method using the writings of Hume and Popper.
The first method I will look at is the rt method which is built upon collected data from surveys etc. Its main plus points being that it uses a much larger sample than the other methods because it takes less time to collate the results. It is also useful because it allows for further research to be added - it can be updated. There are a number of problems with this. The subjects may not feel comfortable and could answer just to please the experimenter. A big problem with the method is that it does not give enough range for the subject. They are restricted within the boundaries of the tick boxes. The researcher can only learn so much.
The laboratory experiment gives the experimenter a greater chance to control the conditions and enables you to measure behaviour with greater precision. This method also allows for quantative research and also enables greater control of variables. Although it gives the experimenter greater control, this can also seem daunting to the subject who may feel more uncomfortable and is less likely to ...
Jaegwon Kim thinks that multiple realizability of mental properties would bring about the conclusion that psychology is most likely not a science. Several functionalists, specially, Fodor, take up the opposing stance to Kim, supporting that the multiple realizability of mental states is one of the reasons why psychology is an autonomous and justifiable science. Essentially, Kim think that in order for mental states to be multiply realizable then psychology must be fundamentally broken; with human psychology encompassing properties realized for humans and alien psychology encompassing those mental states realized in the alien way etc. I will demonstrate that even if one supports and allows the principles behind Kim’s argument they do not result in his final conclusion of psychology failing to be a science. By attacking his principle of Casual Individuation of Kinds I will show that Kim has failed to find the correct conclusion. Furthermore, I will consider a possible objection that Kim might have to my stance and give a short rebuttle. I will conclude by explicating Jerry Fodor’s account of what is Kim’s essential problem is. By showing that Kim’s conclusion fails it will entail that Fodor’s conclusion is more viable in reality.
Experimental research is the one type of research that allows psychologists to make causal statements. It is where the researcher changes one or more variables that may have an effect on some other variables (King, 2016). The hypothesis is a specific expectation about what is going to happen in the experiment (King, 2016). In the research, the hypothesis was that women would perceive fat talk to be more socially acceptable than men (Katrevich et al., 2014). The other elements of experimental method are dependent and independent variables. The independent variable (IV) is the cause of the results, and it is changed by the experimenter to find the effects, but the dependent vari...
The study of psychology began as a theoretical subject a branch of ancient philosophy, and later as a part of biological sciences and physiology. However, over the years, it has grown into a rigorous science and a separate discipline, with its own sets of guidance and experimental techniques. This paper aims to study the various stages that the science of psychology passed through to reach its contemporary status, and their effects on its development. It begins with an overview of the historical and philosophical basis of psychology, discusses the development of the various schools of thought, and highlights their effects on contemporary personal and professional decision-making.
In order to have a successful, reliable experiment you need sufficient data and evidence, reliable research, variables to test and a follow – up experiment. There are several types of variables you need to do an experiment. An independent variable is the manipulated experimental factor that is changed to see what the effects are. A dependent variable is the outcome. This factor can change in an experiment in reaction to the changes in the independent variable. An experimental group is the group of participants that are exposed to the change that the independent variable represents. The control group is participants who are treated in the same way as the experimental group except for the manipulated factor which is the independent variable (King 24). Proper data, evidence and research is also needed so the experiment turns out correctly and you know what you are testing. A follow – up experiment is not required, however it helps the validity of the conclusion of the experiment. Validity is “the soundness of the conclusions that a researcher draws from an experiment” (King 25). Conducting a follow – up experiment will help researchers and people alike see if the experiment worked properly, continues to help people and see how participants are doing after the experiment is over.
In order for an experiment to be considered a true experimental design, the design must fit specific criteria. The researcher must have a hypothesis for a cause and effect relationship between variables, the treatment group, the control group, random selection for the treatment group, and random assignment for the control group. In a simple experiment, the researcher forms two groups that are similar or equivalent, through probability, to each other in every way possible appropriate to the concept of experiment. The treatment group receives the procedure for the experiment and the control group does not. Therefore, the only difference between the groups will be that one group receives the treatment for the experiment and one group does note. After the experiment is conducted the researcher analysis the results in both groups.
One advantage of laboratory research is that the research can better establish causality through reducing the number of confounds via a controlled environment like lab setting. The disadvantages of laboratory research are the results may be artificial and not applied to the real world; there may be research bias.
The British Psychological Society states that ‘Psychology is the scientific study of people, the mind and behaviour’ (BPS). In this essay I will be discussing what is actually meant by this and whether psychology fits into both the traditional views of a science, as well as more contemporary perspectives. It is widely suggested that Psychology is a “coalition of specialities” meaning it is multi-disciplinary (Hewstone, Fincham and Foster 2005, page 4). I will therefore examine whether it could be considered wrong to think that all parts of the discipline should neatly fit into one view of a scientific approach.
Psychology practices also use the Scientific Method as a fundamental in collecting research. Scientists who will test a theory, will go through the method of testing their hypothesis and conducting a measurable experiment to record and analyse results that conclude if their hypothesis was correct or not. Pseudoscience, however, doesn’t record the same principles as psychology. Karl Popper, a recognisably important philosopher of science, made a distinction between science and a ‘non-science’, which relates to the term, ‘demarcation.’ Scientists conduct experiments in order to collect reliable results that confirm or disprove their hypothesis, while philosophers, such as Popper, are interested in the validity of the factors leading to the experimenter’s scientific results.
The first method to be discussed and analysed are experimental methods. There is a variety of experimental methods including; laboratory, field and natural experiments. These methods are the most scientific method due to them being highly objective and systematic. In addition, this method is regarded as the most powerful research method used in psychology because of the potential to investigate the causes of events and therefore, identifying the cause and effect relationship. When carrying out an experiment the researcher intervenes directly in the situation being investigated. The researcher manipulates an independent variable (IV) in order to investigate whether there is a change in the dependent variable (DV). Any other variables that could have an
I never noticed how much psychology could be incorporated into everyday life. But really, any decision or action you take is related to it. I have personally been extremely interested in social psychology: why people do things because of social norms, what people do in order to look socially acceptable, etc. Others topics I also find interesting are sensation and perception; how past experiences can influence how you perceive the things around you, states of consciousness; how things that have happened in your day can be transferred into a mash of events in your dreams, motivation and emotion; what makes a person do something or what makes a person start or stop procrastination, and lastly: personality; what characteristics and traits stand out the most in a person, what makes a person who they are.
Although their methods are not as up close and personal as those who study using the clinical method, they are certainly valuable. Experimental research is often regarded as the best form of research, due to its strict adherence to rigid research guidelines. Although neither of these two methods are infallible, each has its own merits and downfalls. In order to be best able to critique these methods one must have a general knowledge of each method, and an understanding of what has allowed them their staying power in the field of psychological research. The Clinical Research MethodThe clinical method of personality research developed literally at the patient’s bedside. During this time in the life of psychoanalytic research, the subjects were usually afflicted with one type of psychotic disorder or another.
Compare and evaluate the ways in which literature on the one hand, and the human sciences on the other may help us to know and understand human behaviour.
Facts are defined as a true knowledge component. Disagreement, however, would be the lack of consensus or correspondence. If experts in a discipline are exposed to the same true facts, then how and why does disagreement occur? By relying on the areas of knowledge of natural sciences and psychology, the answer to that question will be examined. These two cases give different perspective to that controversy considering that disagreement in natural sciences is negatively viewed as a fallacy since facts in this areas are thought to be either right or wrong and contradictions could lead to a loss of faith in science. In contrast, to disagreements in psychology are viewed as different valid interpretations giving us a better insight on a specific
The most significant feature of an investigative study is the precision and simplicity of the investigative problem. For a brief assertion, it definitely has a great deal of influence on the study. The statement of the problem is the central position of the study. The problem statement should affirm what will be studied, whether the study will be completed by means of experimental or non-experimental analysis, and what the reason and function of the results will bring. As an element of the opening, profound problem declarations satisfies the query of why the study should to be performed. The reason of this essay is to discuss the features of an investigative problem; in addition, the essay will center on what constitutes a researchable problem; the components of a well formed Statement of Research Problem; and, what constitutes a reasonable theoretical framework for the need of a study.
The advantages of conducting laboratory research is that it is controlled, therefore it is easier
