This essay will look at difference between to research methods; Case Study and Observation. Case study is the understanding of the complex issues or can extend experience or add strength to what is already known through previous research. It is an in-depth study of an individual, group, incident or community. Case studies emphasize on the detailed analysis of the event or conditions and their relationship. Sometimes researchers use the case study method for real life situations and use sources of evidence to prove their study. First step to take in case study is to collect all data about the case and should be organised to draw attention to important points in the case. The case study's questions are most likely to be information questions "why "and "How "therefore these questions are helpful to focus on the study's goal. In case study researchers gather facts from different sources and conclusions is made of these facts. Here is a case study of the David's behaviour," David, 13 year old who has been admitted to a detention facility in California. Police reports indicate that he and another boy were arrested for breaking and entering into a private residence. David grew up in an upper middle class section of California. David's father is a professor at a college, and his mother, is a dentist who works for a health care group. Even as a small child, David seemed unable to restrain himself. He would bound around the house, crashing into walls and objects, frequently breaking items or destroying house plants. David entered puberty at the age of 11, and at that time, his behaviours became more destructive. He frequently got in fights with his classmates, and would verbally assault teachers. His parents suspect that he may have tried smoking cigarettes and may have experimented with sniffing glue. After his arrest for breaking and entering, David began to cry and told his parents that he felt badly for what he had done. He added that he was unable to control himself."
In David's case study which took long time to study David's behaviour from his childhood to his teenage and in different circumstances David's behaviour had changed and resources have been used to prove his behaviour such as his parents or police.
Another example for case study research; it's Freud's little Hans case study, "Freud used a case study method to investigate little Hans' Phobia however the case study was actually carried out by the boy's father who was a friend of Freud. Freud probably only met the boy once. The father reported to Freud via correspondence and Freud gave directions as how to deal with the situation based on his interpretations of his father's reports. Freud noted that it was the special relationship between Hans and his father that allowed the analysis to progress and for the discussions with the boy to be so detailed and so intimate. The first reports of Hans are when he was 3 years old. When Hans was almost 5, Han's father wrote to Freud explaining his concerns about Hans. He described the main problem as follows:' he is afraid of horse will bite him in the street, at age 19 the not so little Hans appeared at Freud's consulting room having read his case history. Freud believed that the findings from the case little Hans supported his theories of child development."
Observation involves looking and listening to the object very carefully. Researchers in observation study an individual or group in their natural settings without being informed of the observation in advance. Observational data is usually detailed information about the particular person, groups or situations and revealing changes.
In a non- participant observation researchers observe behaviour of the subject without interacting with the subject whereas in participant observation the researchers put themselves in the subject's position, so the researchers become part of the world of the subject meanwhile focusing on their study and in direct observation, people know that you are watching them, and there is concern that sometimes individuals change their actions while not showing what you are looking for or what they are really look like.
A research which led by Charlton, "studied the effect of television on children's behaviour when it was introduced for the first time to an island of St Helena in mid-1990s, The researchers focused specifically on pro- and anti- social behaviour. Using video recording, they found that, compared with play ground observation on three to eight years olds made four months before television started, five year after its introduction there were 5 out of 64 measures showing a decrease in pro- social behaviour. However for boys, only there were significant increase on two pro-social measures and significant decrease on two anti-social measures. In other words, for boys at least there was almost as much positive as negative effect."
The research led by Charlton was a naturalistic observation which is used to collect behavioural data in real life situations. The data gathering device in this research was video recording, which taped the children's interaction daily. There is another example of Whyte studies about Italian gang for Observation research study,
"Whyte studied an Italian street gang in Chicago by joining it. It was obvious Whyte was not a normal gang member. His 'cover' was that he was writing a book about the area. He made the famous statement that 'I began as a non-participating observer. As I became accepted into the community, I found myself becoming almost a non-observing participant'"
Whyte research study was undisclosed participant observation. Whyte as an observer kept hidden his study about the gang from gang members; Whyte aimed the understanding of the gang by putting himself in their position and observed gang members in their natural setting, as they were busy in their everyday lives.
Two ethical issues Consent and Deception, both are very important issues to concentrate on before deciding for a psychological research. Consent should be obtained in an early time of research; this would involves informing the participant about the grounds for the research and their role in the research however there are some cases where this is not required if the research is something in public where they would normally expect to be observed, they would need permission to be observed on the other side in deception, participants should never be deceived about any aspect of the study they are taking part in. Same as consent participants should be provided with sufficient information at the earliest stage.
Other ethical issues are, introduction where both sides confidence is needed between the researcher and the participants, and the data protection act protects participants in the research, therefore confidentiality and privacy is important to be agreed on both sides except in situation where the human life is in danger. And participants must be informed of their right to withdraw from the research at any stage of the research. After debriefing, participants have the right to ask for their details in the study to be destroyed in their presence. Participants should not be asked to risk their life in any circumstances during the study.
Publication is another important part of the ethical issues, it's the responsibility of the researcher to publish is his research, this is because if the research is failed which has costs lot of time and money someone else might have the same idea and might invest lots of time and money, which would be wasted.
It's the researcher responsibility to monitor his colleagues in a research to ensure that code is being followed and if the researcher becomes aware of the participants problems in the study, so the researcher should refer them to someone qualified to advise them on the issue if the participants wish to.
In Zimbardo's Stanford prison experiment, participants were deceived and were physically harmed, they have not been informed properly about all that took place later in the research, therefore deception is not allowed in any circumstances and all that are going to take place in a research should be told to participant in a earlier stage. And the participants consent was not obtained before the research and participants have not been informed of the reason of the study
This involves informing the participant of the reasons for the study and what is expected of them. There are few cases where this is not required: if someone is doing something in public where they would normally expect to be observed, they are giving permission to be observed.
