Observational Studies - Essay ExampleEven research that would seem, from a contemporary perspective, to be ideally suited as an ceremonyal study, like the characterization do in the 1920s by Arnold Gesell of the normal course of human development in the first 6 age of life, was carried out in a laboratory setting and followed stringent rules (Naturalistic results, 2004).An reflectivityal study (also called an epidemiological or population study), therefore is a research method that looks at large populations with an aim to find trends. It is commonly retrospective that is, it examines what has happened in the past. For example, trigger officipants may fill out surveys or questionnaires on what they recall about feature looks, such as what foods they ate or what nutritional supplements they took in past years. Researchers simply look at what is already going on. Such research methods are often used to find connections between what sight eat and the development of different d iseases (Observational study, 2006). Observational studies include several observation methods such as naturalistic observation, analog observation, self observation, and narrative observation.Naturalistic observation occurs when a researcher does observations in a course occurring situation, without having to get involved. In using the naturalistic observations method, the researcher makes no effort to control or mixture the situation. The research task is simply to make a comprehensive record of the proceedings that occur and of visual relationships between events. The main challenge in conducting naturalistic observation is to arrange the data collection so that the observer has a clear view of what occurs, but is not so prominent or marked that they become an object of interest or concern to participants (Naturalistic observation, n.d.). Examples of naturalistic observations without intervention include the early bat of Jane Goodall on chimpanzees and of Dian Fossey on moun tain gorillas as well as Timothy Perpers studies of flirting behavior in bars. Examples of naturalistic observation with intervention include participant observation studies in which a researcher becomes part of a group in order to describe what members of the group do (Naturalistic research, 2004). Analogue observations Analogue observation involves the measurement of a clients obvious behavior in an artificial setting that is analogous to settings that the client is pass judgment to encounter in his natural surroundings. The goal of analogue behavioural observation is to derive reliable estimates of the clients behavior in a current or future natural environment. The disadvantage of Analogue behavioral observation is that its instruments are often developed with insufficient attention to their psychometric properties, especially content weight. Although analogue behavioral observation instruments can be susceptible to change, their validity can corrode as time passes and is impa ct by various sources of discrepancy. However, analogue behavioral observation assessment is especially useful in detective work significant functional relations in clinical assessment (PsycINFO Database Record (c) 2005 APA, all rights reserved
