Explain how one principle of the biological level of analysis may be demonstrated in one empirical study or theory Biological Level of Analysis (BLOA) deals with biological adaptations at a biological level. BLOA states that cognitions, emotions and behaviours have a physiological basis to all of them. There are 3 main principles that revolve and outline the BLOA. Foremost, Behaviour is innate, as it is genetically based, so it rational to conclude that behaviour is genetically influenced by evolution. Secondly, Animal research may inform our understanding of human behaviour, as to why a lot of research is done on animals. Lastly, Cognitions, emotions and behaviours are products of than anatomy and physiology of our nervous and endocrine…show more content…
In Charles Darwin’s theory of natural selection, he referred that any trait that is useful will be kept. For that trait to occur is a change in adaptation to environment factors. He also believed that humans were similar in behavioural traits to primates (Mate selection, maternal love and self-preservation). Matsuzawa in 2007, attempted to test the spacial memory in humans in comparison to chimpanzees. He trained 3 young chimpanzees to recognize numbers from 1-9 on a computer screen. Then, he directed the chimpanzee and human subjects to sit at computer terminals. The computers would flash 1-9 on the screen, and then the numbers would be hidden with white squares. They were asked to locate of the numbers in sequence of the white squares. With each time trial, the numbers that were visible were shortened. Humans made more errors this way, as the interval of time were shortened, as the chimpanzees did not fluctuate in errors or timing. Concluding that the spacial memory was a necessary adaptation trait for chimpanzees to survive, that humans didn’t necessary need. Matsuzawa’s study demonstrates the principle of BLOA because of the behavioural traits of humans and chimpanzees. Chimpanzees share 96% of DNA of humans, which can inform us that although they are genetically similar, this study informs our understanding that adaptation forms differently towards people and animals and so it helps us understand the distinct behavioural traits so that
