Advantages of the use of the scientific method in psychology There are a number of advantages to using scientific methods in psychology. Firstly an important aspect of imperial data is that it is objective, i.e. not affected by expectations of the research. So, without objectivity we have no way of being certain that data collected is valid. An example of this is seen with Gardner & Gardner. When they observed Washoe they might have judged that Washoe was using real words because they wanted her to succeed, for that reason the Gardners developed a strict set of criteria to make judgements. This shows that through objectivity it allows for there to be no bias evident. Another advantage is that the scientific method allows for…show more content…

The Humanistic Approach began in response to concerns by therapists against perceived limitations of Psychodynamic theories. They were different from other approaches because they showed emphasis on subjective meaning and a rejection of determinism. Finally the cognitive approach developed as a separate area within the discipline since the late 1950s and early 1960s following the "cognitive revolution" initiated by Chomsky's critique of behaviourism. It accepts the use of the scientific method, and generally rejects introspection as a valid method of investigation. Finally laboratory experiments are considered the most scientific method of research as it allows research to be controlled; objective and replicable. Whereas the least scientific method is considered to be case studies, these generalise from one person’s experiences and often let the researcher become ‘attached’ to the subject. For
