Biological Psychology Worksheet Essay

Biological Psychology Worksheet Answer the following questions in short-essay format. Each response should be 200-300 words. Be prepared to discuss your answers. 1. What is biological psychology? Biological psychology is a major neuroscientific discipline that looks at the way the brain functions in relation to an individual’s behavior. Biological psychology is the study of the biology of behavior through the scientific approach. This approach focuses on the biological aspects of behavior and how genetics plays a role in the way an individual acts and reacts to different stimuli along with different situations.

The cells of the human body send encoded messages throughout the body from the brain to tell the individual how to react. Psychology in general is the study of behavior that focuses on all the behavioral activities which can include learning, memory, perception, emotions, motivations and feelings 2. What is the historical development of biological psychology? Biological psychology did not become a major neuroscientific discipline until the 20th century. There is not a specific date that sparked the beginning of biological psychology but D. O.

Hebb’s publication of The Organization of Behavior in 1949 played a key role in biological psychology becoming a major neuroscientific discipline. D. O. Hebb was the first to devise a theory that showed that perception, memory, thoughts and emotions could be produced by brain activity. D. O. Hebb’s theory helped to discredit the view that people had that believed psychological functioning was too complex to have ties with physiology and chemistry of the brain. Biological psychology is still a relatively new discipline that does not have a complex history but it is rapidly growing with the current research that is being done. . Name one to three important theorists associated with biological psychology. Biological psychology has roots in biology, genetics and neuroscience and there are three important theorists who helped biological psychology become a major discipline. Charles Darwin who published On the Origin of Species in 1859 was a key figure in the development of biology. Charles Darwin’s theory of evolution was the first to show evidence that species do evolve in order to acclimate to new environments and survive predators. Natural selection in which only the fittest survive is also a reason for species to evolve in order to survive.

Gregor Mendel an Augustinian monk played an instrumental role in genetics which has also been instrumental in understanding how genetics play a role in the functions of the brain and the behavior that follows. In order to understand how offspring got their traits from their parents, Gregor Mendel studied the inheritance of genes in pea plants. These discoveries in genetics laid the ground work for the later studies that would reveal that more than physical appearance can be inherited through an individual’s genes like autism or bipolar disease.

D. O. Hebb’s theory which showed that perception, memory, thoughts and emotions could be produced by brain activity and the publication of The organization of Behavior helped biological psychology become a major discipline. This was possible when D. O. Hebb’s theory discredited the view that psychological functioning was too complex a function to be included in physiology and chemistry. 4. Describe the relationship between biological psychology and other fields in psychology and neuroscience.

Biological psychology has strong ties with numerous neuroscientific divisions along with different divisions oh psychology. Neuroanatomy, neurochemistry, neuroendocrinology, neuropathology, neuropharmacology, and neurophysiology all play key roles in biological psychology. These neuroscientific divisions relate to the nervous system and how they are involved in the functions and activities in the nervous system. Biological psychology uses these principles to look for a connection between the nervous system and the way that an individual behaves.

While the neuroscientific divisions look at the nervous system which can be related to biological psychology. Physiological psychology takes what is known about the neural mechanisms from neuroscience and manipulates the brain in order to understand behavior. Psychopharmacology also looks at the manipulation of the brain and behavior but this manipulation is based on drugs. Neuropsychology focuses on the brain damage in human patients and how this affects behavior. Psychophysiology studies physiological activity and the psychological process.

These psychological divisions focus on the behaviors of human patients in different situations and between the neurosciences and the divisions of psychology both offer the necessary information from studies that give biological psychology enough information to make biological psychology a major division. 5. Describe the major underlying assumptions of a biopsychological approach. The major underlying assumption of the biopsychological approach is the connection between biology and psychology. Biological psychology looks the manipulations of the brain in order to find a treatment for the mental illnesses that are caused by genetics.

The information gained from these studies not only looks for a way to help treat illnesses but what is the cause of the mental illness. If the cause of the mental illness can be found there might be possibilities of how to keep them from happening. Biological advances are being studied to manipulate the genetics of individuals in order to take away gene mutations before a baby is born. Through the research done in biology and biological psychology gene mutations which cause mental illnesses might become a thing of the past so that individuals can lead healthy lives.
