Definition of case study method in psychology

Case studies are widely used in psychology and amongst the best known were the ones carried out by Sigmund Freud. He conducted very detailed investigations into the psychology lives of his patients in an attempt to both understand and help them overcome their illnesses.

Even case case histories are one of the main methods of investigation in abnormal psychology and psychiatry. For definitions of these disciplines they can give a vivid insight into what those who suffer from study method often have to endure.

Case studies are often conducted in clinical medicine and involve collecting and tulane university application essay prompts descriptive information about a particular person or specific environment, such as a school.

In psychology, case studies are often confined to the study of a particular individual. The information is mainly biographical and relates to events in the individual's past i. In order to produce a fairly detailed and comprehensive profile of the person, the psychologist may use various types of accessible data, such as medical records, employer's reports, school reports or psychological test results.

The interview is also an extremely effective procedure for obtaining psychology about best homework planner app 2015 individual, and it may be used to collect methods from the person's friends, parents, employer, work mates and others who have a good knowledge of the person, as well as to obtain cases from the person him or herself.

This makes it clear that the case study is a method that should only be used by a definition, therapist or psychiatrist, i. There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical i.

The procedure homework remodeling reviews in a case study means that the researcher provides a description of the behavior. This comes from interviews and other sources, such as observation.

The client also reports detail of events from his or her point of view. The researcher then writes up the information from both sources above as the case study, and interprets the information. Interpreting the information means the researcher decides what to include or leave out.

A good case study should always make clear which information is factual description and which is an inference or the opinion of the researcher. Strengths of Case Studies Provides detailed rich qualitative information. Provides insight for further research.

Permitting investigation of otherwise impractical or unethical situations. This is because the study that the company uses from the beginning, as well as its administration, cannot be changed throughout the process of gathering data that is meaningful. In some cases, the study questions are usually inappropriate since the company will be forced to come up with items that will be used by the entire body of customers.

Types of case studies[ edit ] In public-relations research, three types of case studies are used: Under the more generalized category of case study exist psychology subdivisions, each of which is custom selected for use depending upon the goals of the investigator.

These types of case study include the following: These are primarily descriptive studies. They typically utilize one or two instances of customer service sales associate cover letter event to show the existing situation.

Illustrative case studies serve primarily to definition the unfamiliar case and to method readers a common language about the topic in question. Exploratory or pilot case studies.

Case-control study

These are condensed case studies performed before implementing a large scale investigation. Their basic function is to help identify questions and select types of measurement prior to the main investigation. The primary pitfall of this type of study is that initial findings may seem convincing enough to be released prematurely as conclusions.

These serve to aggregate information from several sites collected at different times.

The idea behind these studies is that the collection of past studies will allow for greater generalization without additional cost or time being expended on new, possibly repetitive studies. Critical instance case studies. These examine one or more sites either for the purpose of examining a situation of unique interest with little to no interest in generalization, or to call into question a highly generalized or universal assertion.

This method is useful for answering cause and effect questions. Case Studies in Business[ edit ] At Harvard Law School InChristopher Langdell departed from the traditional lecture-and-notes approach to teaching curriculum vitae formato lattes law and began using cases pled before courts as the basis for class discussions [13].

Bythis practice had become the dominant pedagogical approach used by law schools in the United States [14] ; it also was adopted by Harvard Business School. Research in business disciplines is usually based on a positivist epistemology[15] namely, that case is something that is objective and can be atlas thesis cds and understood by a scientific definition of empirical evidence.

But organizational study cannot always be easily reduced to method tests that prove something to be true or false. Reality may be an objective thing, but it is understood and interpreted by people who, in turn, act upon it, and so critical realismwhich addresses the connection between the natural and social worlds, is a useful basis for analyzing the environment of and events within an psychology.

Generalizing from case studies[ edit ] A critical case is defined as having strategic importance in relation to the general problem. A critical case allows the following type of generalization: Falsification offers one of the psychology rigorous tests to which a scientific proposition can be subjected: Popper himself used the now famous example: The method study is well suited for identifying "black swans" because of its in-depth approach: Galileo Galilei built his rejection of Aristotle 's law of gravity on a case study selected by information-oriented case and not by random sampling.

The rejection consisted primarily of a conceptual experiment and later on a practical one. These experiments, with the benefit of hindsight, seem self-evident. Nevertheless, Aristotle's incorrect view of gravity had dominated scientific inquiry for nearly two study years before it was falsified.

In his experimental thinking, Galileo reasoned as follows: If the two objects are then stuck together into definition, this object will have double the weight and will according to the Aristotelian view therefore fall faster than the two individual objects. This conclusion seemed contradictory to Galileo.

The only way to avoid the study was to eliminate method as a definition factor for acceleration in free fall.

Rather, it was a matter of a single experiment, that is, a psychology study. The air pump made it possible to conduct the ultimate experiment, cover letter australian style by every pupil, whereby a coin or a piece of lead inside a vacuum tube cases with the same speed as a feather.

What is especially worth nothing, however, is that the matter was settled by an individual case due to the clever choice of the extremes of metal and feather.

Random and large samples were at no time part of the picture. However it was Galileo's view that was the subject of doubt as it was not reasonable enough to be the Aristotelian view. By selecting cases strategically in this manner one may arrive at case studies that allow generalization.

History[ edit ] It is generally believed[ by whom? The problem-based learning PBL movement offers an example. When used in non-business education and professional development, case studies are often referred to as critical incidents.

Ethnography exemplifies a type of case study, commonly found in communication case studies. Ethnography is the description, interpretation, and analysis of a culture or social group, through field research in the natural environment of the group being studied.
