Advantages of the Use of the Scientific Method in Psychology

Advantages of the utilization of the scientific technique in psychology There are an a wide range of benefits to utilizing scientific strategies in psychology. Firstly an important facet of imperial data is that it is goal, i. e. not affected by expectations of the research. So, without objectivity we now have no way of being certain that data collected is valid. An instance of this is seen with Gardner & Gardner. When they observed Washoe they may have judged that Washoe was using actual words because they wanted her to succeed, for that purpose the Gardners developed a strict set of standards to make judgements.

This reveals that by way of objectivity it allows for there to be no bias evident. Another advantage is that the scientific method permits for control. Laboratory experiment allows researchers to demonstrate causal relationships. The experimental technique is the one way to do that – where we range one issue (IV) and observe its results of the DV. It order for this to be a fair test, all over situations should be managed and the best place for it is a laboratory.

This is an advantage because if we can’t demonstrate causal relationships then we can’t be sure that, for an example, an individual anxiety was decreased by the drug used.

Also the scientific methodology permits replication. If scientists report their methods and standardise them fastidiously so the identical procedures can be adopted in the future, i. e. replicated. This is a bonus as a end result of by repeating a examine is an important method to demonstrate the validity of any remark or experiment.

If the result is similar this affirms the reality of the unique outcomes. An example the place this might be seen is with Milgram and his research not having ecological validity.

But the fact it has be replicated means that the examine does have ecological validity. Throughout the historical past of psychology they’ve moved from Psychodynamic to behaviourism to humanistic and finally to cognitive. This is recognized as the Fundamental Shifts in Psychology. Freud first developed the fundamental ideas which underline the approach as an entire. This method was not seen as scientific, although Freud tried to develop the science of psycho-analysis. Psychology then moved right into a behaviourist strategy which rejected the mphasis on both the aware and unconscious thoughts. Instead, behaviourism strove to make psychology a more scientific self-discipline by focusing purely on observable behaviour. Pavlov’s research with canines led to his discovery of the classical conditioning process. Then the humanists got here into play and the end result was not merely new variations on psychodynamic concept, however somewhat a essentially new method. The Humanistic Approach began in response to considerations by therapists in opposition to perceived limitations of Psychodynamic theories.

They have been completely different from different approaches as a outcome of they confirmed emphasis on subjective meaning and a rejection of determinism. Finally the cognitive method developed as a separate area inside the self-discipline for the rationale that late Nineteen Fifties and early Nineteen Sixties 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 legitimate methodology of investigation. Finally laboratory experiments are thought-about essentially the most scientific methodology of research because it permits analysis to be managed; objective and replicable.

Whereas the least scientific method is taken into account to be case studies, these generalise from one person’s experiences and often let the researcher turn into ‘attached’ to the subject. For example Loftus and Palmer did an experiment the place 45 students have been shown seven films of a traffic accident, these movie segments ranged from 5-30 seconds. Participants acquired a questionnaire in which they were asked to “give an account of the accident you could have just seen”. Participants have been then divided into five groups of nine participants. Each group was given a barely completely different specific question about the accident.

So, advantages of utilizing laboratory experiments is that it gave Loftus & Palmer greater control over confounding variables similar to environment the movies were watched in. It additionally makes it simpler to replicate analysis to check findings about EWT are reliable. Case studies however, relate to single instances so it’s not attainable to generalise to other individuals. The results of the research are only valid when utilized to that case. Also a case examine realises on qualitative rather than quantitative evaluation, there’s a danger that behaviour is interpreted in the finest way the researcher needs (subjective).

An instance of this could be seen with Freud and his research ‘little Hans’. Hans was a 5 year old boy dropped at Freud’s attention by the boy’s father as a result of he had a phobia of horses pulling laden carts. The drawback with this case study is that by Han’s father utilizing leading questions it means that Hans’s answers might nicely have been influenced by his father’s expectations. So, as you can see there are numerous advantages of using scientific methods in psychology as it allows for results to be controlled, goal, replicable and as a result legitimate.
