Comparative psychology
Comparative psychology studies have been used by scientists to get intensive information about the human cognitive process and historically find evolutionary roots. Cognition refers to mental processes involved in absorbing knowledge and understanding. These processes are like thinking, remembering, knowing, and judging, which are higher-level brain function and requires imagination, language, perception, and planning. People use rational thinking based on opinion to create knowledge, which is called rationalism. Human beings also use empiricism, which is observing the surrounding world to create an experience.
This cognition uses brains working memory to temporarily store the gained knowledge for later use, which can be in thousands. Recent research findings of the evolutionary origin of this cognitive mechanism have shown that working memory also exists in small mammals like rodents (Eysenck & Keane 2015). Based on evolutionary evidence, each social cognitive device has its origin in animals, mostly primates. Studying the source of these mechanisms helps in understanding and gaining a more profound knowledge of how thy work. Scientific researches of human cognitive development depend on indirect sources of information like nonhuman cognition primates, material artifacts, and fossils left behind bat various periods of evolution by humans and cultural cognitive mechanisms used by modern human populations.
These scientific studies have shed some light on how human brain works based on things that go inside our heads. These mental processes and thoughts influence our actions, as shown by studying what cognition involves. Different fields of medicine like psychology continue to help us understand how memories of past events, attention to the world around us, understanding of language, how the world works, and the ability to solve problems all contribute to how we interact and behave with our immediate environment. Psychology is always evolving with new areas and branches emerging to contribute to our understanding of various psychological factors that influence who we are, how we behave, and how we think. We are using mental knowledge to tackle the challenges we may face in our lives.
