Biological psychology is unlike any other branch of psychological study. While other areas of psychology, such as cognitive and clinical psychology, focus on statistics and observation, biological psychology focuses on the biological reasoning for behavior. Biological psychology is used in neuropsychology as well as the practice of psychiatry. Biological psychology “is a hybrid of neuroscience and psychology used to examine the knowledge of the brain to treat patients” (Helium, 2002-2010).
Biological psychology is the study of the biological reasoning behind the foundation of human behavior. Physiological psychologies, clinical neuropsychology, behavioral neuroscience, and biopsychology are all names used to describe or define the area of biological psychology (Wickens, 2005, p. 3). Biological psychology attempts to find a chemical or biological reasoning for mental illnesses including schizophrenia, bipolar disease, and depression. Biological psychology studies human emotions and behaviors and attempts to find a system to deal with psychological problems, much like other forms of psychology. The thing that makes biological psychology different is the way that information is viewed and processed. While other avenues of psychology look at issues from a clinical view, biological psychology looks at issues with a scientific or biological view.
The ancient Greeks were the first documentation of the realization that the brain has psychological and physiological importance. As a result of this realization, the Greeks began to study the human brain. Plato was the first theorist to resolve that human reasoning and emotions come from the brain. He also believed that the mind and the body serve a separate purpose. After Plato, Aristotle theorized that there is a close relationship between physiological and psychological processes. “In the 20th Century biopsychology entered into the area of scientific research” (Wickens, 2005). Galen theorized about the human heart, but stated that the four ventricles of the brain were the source of human behaviors. Nemesius, a Roman theorist and follower of Galen, said that the lateral ventricles as the source from which mental impressions were derived. He also theorized that the third ventricle was the home of reasoning and that the fourth ventricle was where memory was contained (Wickens, 2005). Donald O. Hebb’s research in the fifteenth century concluded that psychological functioning could be studied in conjunction with chemistry and physiology of the brain.
Rene Descartes was another notable psychological theorist. Descartes agreed with Plato, but believed that the mind and the body, although separate entities, worked together to serve a purpose. He believed that behaviors were caused by animal spirits. “He held a mechanistic view arrived at because of the statues of St. Germaine. Descartes thought humans followed the same pattern as the statues with water flowing through tubes, representing nerves and the fluid that result in muscle stimulation” (Millis, n.d.). Descartes planted the seed that human behavior may not be based solely on emotions, but also on anatomy and biological reasoning.
Thomas Willis took Descartes’ views one step further. He believed that the structures of the human brain influenced behaviors. “Willis is responsible for discovering the gray and white matter within the brain (Hub Pages, 2010). Willis, like Descartes, believed that spirits influenced human behaviors, but he believed that the spirits were created in the grey matter and distributed by the white matter in the brain (Hub Pages, 2010).
Many branches of psychology focus on phenomena. Unlike these areas of psychology, biological psychology is classified by method (Hub Pages, 2010). While many areas of psychology study group behavior or case studies, biological psychology studies the chemical or biological reason for the behavior. Biological psychology focuses not on what behavior occurs, rather it studies the reason the behavior occurred in the first place. “Research accomplished within the field contributes to developmental psychology in the assistance of understanding memory, motivation, perceptions, cognition, learning and emotions” (Ertel, 2004). Biological psychologists work in neuroscience, neuropsychology, behavioral genetics, psychopharmacology, and psychiatry. These fields are all very different, but all depend greatly on biological psychology. These fields are able to take biological psychology and use it for very different things to accomplish the resolution of each individual task.
Biological psychology assumes that there is a biological basis to mental processes. Biological psychologists do research and present the evidence to prove their theories. Both medication and discussion are used in the treatment of mental issues when using biological psychology. “The biological approach in psychology focuses more on the individual and the genetic makeup than the environmental influence on the individual” (Hub Pages, 2010). Heredity and chemical imbalances are more important to biological psychology than in other forms of psychology. Conversely, societal impact is less important in biological psychology than in other forms of psychology, where social impact is extremely important.
There are several forms of psychology, but not that are as scientific as biological psychology. Biological psychology allows psychology to look into neuroscience and physiology. Biological psychology focuses on the biological reasoning for human behavior. Environment and genetics both have an impact on human behavior. In order to examine both of these causes of human behavior, both biological psychology and sociological psychology must be put to use. Because of biological psychology medication is available to people suffering from mental illness.
