AC 2
Firstly, I am going to explain the research method used by the psychologists in each article.
In the ‘The science of love: Harry Harlow and the Nature of affection’ article by Cherry (ND), laboratory experiments using rhesus monkeys were used by Harry Harlow and his fellow psychologists to study how child development can be affected by the level of motherly love a child receive during early ages.

(United Nation, 1948). This piece of research is quantitative, as Harlow was collecting statistics about the length of time the infant monkeys spent with the ‘cloth’ or ‘wired’ mother.

Animal experiments allow researchers to have maximum control over the variables that might affect the accuracy of the results (McLeod, 2012).

...t on child development, however, the use of animals and human in both researches has been controversial as the participants have suffered from different degrees of distress and psychological traumas. They were both deemed unethical due to the nature of the research. Balancing between using reliable and valid research methods and minimising ethical issues raised in psychological research can sometimes be a challenge to psychologists. However, the code of ethics of psychologists have stated that the welfare of both animals and human should be respected, therefore, if the potential of harm cannot be removed, the psychologists should discontinue with their research on a particular topic as the ultimate goal of all psychologists as per the American Psychological Association’s mission statement, which is to ‘to benefit the society and improving people’s life (APA, 2014).

Essay on Is Psychology a Science?

- The British Psychological Society states that ‘Psychology is the scientific study of people, the mind and behaviour’ (BPS). In this essay I will be discussing what is actually meant by this and whether psychology fits into both the traditional views of a science, as well as more contemporary perspectives.
