In Psychology, in the department of biological level of analysis, scientists research on how biology may affect human behaviour, it focuses on brain, hormones, and genetics. …show more content…
Broca investigated multiple patients who suffered from strokes. In 1861 Broca discovers that the damage in the left frontal lobe of the brain was the cause why patients were unable to understand, speak complex sentences and problems with speech. His famous patient was called Tan, because that was the only word he could say, but also due to anonymity. After Tan’s death, his autopsy revealed that the disability was the result of a specific brain damage in the left frontal lobe, called The Broca's area. Now these conditions of trauma are called Broca’s aphasia. The brian injury in the left, frontal lobe, affected the patient in their speech since that area is the control system of speech, problem solving, and movement, if it’s damaged then it affects these criterias, which is proven in Broca’s Case Study of Tan. This investigation was one of the ones which helped initiate the theory of Localization of Function, since the theory was finally established in 1860s. It demonstrates how facts were used to commence a theory, in sense of the data collected. Broca was provided with the qualitative data, such as behavioural patterns, and the physical state of the brain, which allowed Broca to utilize reasoning in order to expand the theory of …show more content…
It consists of three main principles: (1) All living organisms are composed of cells. They may be unicellular or multicellular. (2) The cell is the basic unit of life. (3) Cells form from preexisting cells. (They are not derived from spontaneous generation.) These principles can be proven by multiple existing organisms in our world, such as Paramecium, a unicellular organism which still completes all the function of a living organism. It nutrition is based on smaller organisms and taking them in through endocytosis, a process in which a cell allows molecules/organism inside of it’s outer shell. Its metabolism is initiated in cytoplasm where it catalyzes metabolic reactions, and diffuse CO2, as excretion material, out of its membrane. Paramecium’s specific structure of cilia ( small hairs outside of the membrane) allow the organism to respond and move due to detected stimuli from its cilia. In order to reproduce it follows through both sexual, and asexual reproduction, mitosis and meiosis. This organism is a fact which was first encountered, and compared to numerous other organisms, such as humans, who also reproduce, process metabolism, etc. Grouping similar organism together allows scientist to utilize their data collection in order to reason their theory. However, in order to establish a theory and
