Biological psychology has its roots in early structuralist and functionalist psychological studies, and as with all of the major perspectives, it has relevance today. certain kinds of depression, are linked to very specific circumstances. There are important gene-environment interactions, also known as epigenetic factors, unique to each individual (even identical twins) which may explain why some individuals with a genetic predisposition toward a certain disorder develop that disorder while others do not (e.g., why one identical twin develops schizophrenia, but the other does not). H.M. suffered such devastating epileptic fits that in the end a surgical technique that had never been used before was tried out. 1. Learn about biological psychology and how it looks at.

Behaviors that aid in survival are more likely to be passed down while those that prove dangerous are less likely to be inherited. These structures include neurons, brain regions, neurotransmitters or genes. Indeed, psychological disorders are at least as complex as why people ex-perience or do anything else. The biological model of psychology says that psychological disorders are caused by biological problems. the proteins produced from these genes affect multiple aspects of brain development, including growth, and organization of neurons. Foundations, Applications, and Integration. For example, one psychologist might look at Norma's depression and say that it is caused by a problem from her childhood. Simply Psychology. The remainder of this chapter focuses on the contributions of biological factors - such as brain structure abnormalities - to the development of psychological disorders. For example, we might want to know whether high intelligence is inherited from one generation to the next. Determine whether the following statements are true or false. By looking at the biological bases of human behavior, psychologists are better able to understand how the brain and physiological processes might influence the way people think, act, and feel. 2.

Figure \(\PageIndex{3}\): Dr. Bruce Cuthbert, Ph.D., director of NIMH's Division of Adult Translational Research, explains the significance of genetic findings for diagnosis and treatment of mental illnesses. Instead of having efficient, strong connections among specific neurons, children with ASD have less efficient connections among neurons. This means the explanations can be scientifically tested and proven.. Despite the improvements in the methods, though, psychosurgery is an absolute last resort and is very rarely used.

Bipolar I disorder This disorder was formerly known as 'manic depression', characterised by extreme emotional highs and extreme emotional lows. Less common biological treatments involve electroconvulsive therapy and psychosurgery. This chapter discusses the biological perspective on psychological disorders, exploring how our brain structures, neural systems, and genetics contribute to the etiology of such disorders as schizophrenia, depression, bipolar, anxiety, and obsessive/compulsion. Highly application to other areas: Biology + Cog = Evolutionary Psy, Ignores mediational processes (doesnt recognize cognitive processes). There are many different perspectives from which to view the human mind and behavior and the biological perspective represents just one of these approaches.

By Kendra Cherry This perspective also allows researchers to come up with new treatments that target the biological influences on psychological well-being. Biological psychology has continually been involved in studying the physical basis for the reception of internal and external stimuli by the nervous system, particularly the visual and auditory systems. A wide range of biological factors like hormonal imbalances, faulty genes, and other factors may have repercussions on the normal functioning and development of individuals. using the frequency of a behavior to determine whether it would be considered abnormal.
