Discuss How and Why Particular Research Methods Are Used at the Biological Level of Analysis

This essay will be looking at the role of ecological validity and the importance it has in psychological research. Ecological validity refers to the extent to which a study reflects naturally occurring or everyday situations. It will also consider the advantages and disadvantages of ecological validity, through exploring studies such as the bobo doll experiment and a study on memory. Ecological validity is one of many important factor in psychological research. Also being addressed is what goes into a study or experiment and all the things that need to be considered to achieve ecological validity. In addition, it is important to design the study in such a way that the results obtained can be usefully and meaningfully applied to the area in question. Constructing experiments that achieve high ecological validity is quite a complex and difficult task.

The biological approach states that “all thoughts, feeling & behavior ultimately have a biological cause” (Simply Psychology). This approach says that we are affected by biological factors. Biological factors are “anything which affects the function and behavior of a living organism. Internally, this factor can be a physical, physiological, chemical, neurological, or genetic condition

Biological To identify contributing biological factors Shares the advantages of the other three methods. Shares the dis-advantages of the other three menthods. One example of biological research would be a CT scan of someone who has a healthy brain and someone who has an injured one and the behavior of both

What is the primary advantage of the experimental method? 2. Read the scenario and answer the questions that follow it. In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep

1. Biological psychology, of biopsychology, is the application of the principles of biology to the study of mental processes in terms of bodily mechanisms. The view that psychological processes have biological (or physiological) correlates, is the basic assumption of the whole field of biological psychology. Biological psychology is a hopeful domain, one that has much to offer in terms of improving the quality of life of the healthy as well as those suffering from disorders. It also contributed important therapeutic data on a variety of conditions, including: Parkinson 's Disease, Alzheimer 's Disease, Clinical depression, Schizophrenia and a lot others. Humans have very complex nervous system, they use neurons and neurotransmitters to make the highest active communication network throughout the body. “most of the body’s neurons are found in the central nervous system(CNS), which consists of the brain and spinal cord” (psychology 5th edition). “Neuroscience emphasizes that the brain and nervous system are central to understanding behavior, thought, and emotion. (Van Horn, 2014; Zhao & others, 2014). Therefore, for biological psychologist all that is psychological is first physiological. All thoughts, feeling & behavior ultimately have a biological cause.” We are benefited from biological approach for diagnosing and treating human brains Ex. Schizophrenia. Scientists are also able to create medications for different types of illnesses. Besides having psychologists

3. Why are researchers concerned about the representativeness of the samples in their studies? a. They don't want to offend anyone. b. They hope to generalize the findings of their studies to populations of interest. c. Representative samples are usually large enough to ensure statistical significance. d. Scientific journals will not publish a study unless the sample is representative. Objective 1.6 Describe the experimental method, state its advantages and disadvantages, and distinguish between independent and dependent variables.

Research Methods in Sociology and Anthropology By Western Governors University Abstract Sociology and Anthropology rely upon investigational and research techniques. While some of these may be similar they also differ. Each discipline has its own philosophical justification for their method but any and all approaches to

Explain how psychological perspectives have been used to criminal behavior Biological approaches: (P1)The biological approach means that our behavior is the cause of biological factors. This approach looks at our genetics to construct a reason why we act the way we do and why we develop abnormal behaviors. The brain and nervous system are the biological approach and so are chemical changes in the body .This can mean chemical reactions in the brain. For instance, in eating disorders - twin studies were carried out and it was shown that if one identical twin suffered from an eating disorder then the other twin would also be more likely to suffer from a disorder as well. This did not happen with non-identical twins, suggesting that the

The Importance of Biology in the Study of Psychology Ashley B. McVey Cecil College Abstract Whether it is the study of biopsychology and other fields of psychology or neuroscience, all psychologists and scientists are trying to understand the functions of the brain. The body and mind connection and how it reacts to certain behaviors or illnesses. Most all psychological functioning can be reduced to underlying brain processes. This should serve as reason alone as to why biology plays an important part in the study of psychology. Psychological factors play a role in whether a person develops a mental illness and in how well they recover from a mental illness, yet biological and genetic risk factors, or predispositions, are

Correlation as a measure of association summary BSHS/435 January 24 2016 Correlation as a measure of association summary Introduction In this essay I will describe correlation is a measure of association as well as describe different methods of establishing a correlation between variables. In this essay I will also explain advantages and disadvantages of each method, were each must be applied, and provide particular circumstances and examples in which a researcher may want to establish correlation

Experimental Designs (Advantage and Disadvantages) Experimental design research tends to use math and statistics to try to prove or disprove a hypothesis. Within an experimental design most of the research is controlled and leaves little room for error. One advantage of experimental design is that it is hard to disprove the results. However, a disadvantage is that because the conditions are controlled that makes the results too perfect. If the same experiment was conducted in an uncontrolled setting, such as the real world, the results would vary.

When becoming a biological psychologist an individual must possess a doctorate degree in psychology. The most common degree for a biological psychologist to possess is a Ph.D. When in school for biological psychology a student is required to do strenuous research. Individuals who want to become biological psychologists need

Throughout this course I have learned many things about research at an introductory level. Research is a critical part of all of our lives in many ways. God blesses each of us with a degree of common sense and we all learn from observing others even as babies, we learned behaviors and skills by observing our parents. Walking through experiences throughout life teach us a lot we need to know as well but sometimes we have to take a better approach when we need to learn about certain things. Many of us know that what works in some situations or with certain individuals doesn’t always work or is the safest option for another situation. Controlled and precisely organized study allows scientists to compare and examine contrasting methods and concepts, also helps them to discover various approaches and be able to learn from individual’s behaviors and experiences. I will act as the case study throughout this paper in order to observe what I have learned about.
