However, it observes the findings that occur only in the natural settings. However, the method sometimes cannot provide clear information because of certain reactions when the researcher is dealing with numerous variables. Different observers may draw varying conclusions from the same observed subjects. Sometimes, individuals may behave in a manner in order to enable the researcher to conform what he or she expected.
Laboratory research method is a research method that enables researchers to control variables through performing experiments and measurements. The psychologist makes experiments by repeating the presentations and dimensions in order to control the desired outcomes. It is advantageous because the researcher can control the confounding variables easily and the experiment takes place in highly natural settings. The researcher can easily replicate the experiments, and it is easy to establish the cause as well as the effects. However, it is advantageous because it requires effective laboratory skills and it consumes time. It also takes place in the artificial settings; hence effected by tiresome practicality.
The case study is a research technique in psychology that entails the use of descriptive measures in order to investigate the subject in details. The psychologists employ varied techniques including personal interviews, archival documentation, direct inspection and psychometric experiments. The method is advantageous because the psychologists can develop a narrative hypothesis effective for testing the hypotheses. The psychologist can provide effective and detailed descriptions of information; thus making further research analysis. However, the technique has few disadvantages. One of them is that the researcher is unable to draw the cause and effect for testing hypotheses. The method enables the researcher to develop or explore varied issues, offer solutions and develop problem-solving skills. It is also difficult for the researcher to
