Biological theories originally attempted to differentiate among individuals on the basis of certain innate physical traits or characteristics these being influenced by genetic or hereditary characteristics. This was one of Lombroso's largest, and most disproved theories, that individuals with more primitive appearances such as broader foreheads or more prominent chins, similar to neanderthals. More popular today though are biological traits that have the greatest effect on neurological traits. These theories attempt to distinguish among individuals on the basis of structural, functional, or chemical differences in the brain or body and how these can be inherited.
In an article titled “biological psychology” by Saul McLeod, he explores several approaches to the biological theory of inherited traits. One of the studies mentioned was one based off twins, ones who have similar genetic makeup to observe the …show more content…
In the novel “Anatomy of Violence” by a psychoanalyst of the name Adrian Raine, he explains his research and how he used PET scans of the brain in 41 violent California prisoners, who either attempted or committed murder, to determine whether their brain anatomy and neurochemistry was different compared to the nonviolent control group. The murderers’ brains showed what appeared to be a significant reduction in the development of the orbitofrontal cortex, the executive function of the brain, compared with the control group. The study suggested that such a deficiency could result in an increased tendency toward a number of behaviors: less control over emotions, such as anger and rage, and factors that lead to greater risk of addiction, such as, less self-control and poor problem-solving capacity. All of these traits might predispose an individual toward
