process that continues to this day. Crime is still a complex and misunderstood phenomenon with no concrete evidence when it comes to human behavior. Throughout time there have been endless amounts of crime theories‚ few of which revolve around biological explanations. We have Cesare Lombroso and the Positive School who thought that criminals were genetically different from the rest of the general population‚ that they were biologically aggressive‚ had criminal traits and/or born as criminals. There is

disorder that affects the persons emotions and distorts how a person perceives the world. The person suffering has confused thoughts and has difficulty telling reality from delusion. It can be described by psychological explanations and biological explanations. A biological explanation of schizophrenia is the dopamine hypothesis‚ amounts of low levels of dopamine in the brain causes a loss of balance and co-ordination‚ it has been found in people with ADHD and Parkinson’s disease. Where as high levels

There are several different explanations for the disorder schizophrenia. One of these explanations is the biological model. This model explains schizophrenia through biological faults‚ for example viral infections and brain abnormalities. Genetic Factors Some psychologists say that schizophrenia can be passed down generations‚ meaning that some people inherit the disorder from their parents. Twin research has consistently shown that identical twins have a greater risk of developing schizophrenia

cognitive and biological. The cognitive perspective suggests that emotion is based more on the factors of the mental processes. The biological perspective suggests that emotion is influenced by biological systems and performances and is based on physiological responses. It has been suggested that there is a possible interaction between cognitive and biological processes that influence emotions. Le Doux’s theory of the biological pathways focuses solely on the biological explanation of emotion‚ whilst

Biological Explanations of Criminal Behavior Nature and nurture contribute to the way a person behaves. This can be applied to the behaviors of criminals. According to Fishbein (1990‚ pg.37)‚ “behavior [is] primarily attributed to inherited predispositions and genetic influences.” Nurture is the environmental influence that shape human behavior (Fishbein‚ 1990‚ pg.37). Human genetics and environmental factors contribute to the uniqueness to a person’s behavior. However‚ there are underlying

How do the four biological explanations fit together to explain schizophrenia or are they mutually exclusive? The biological explanation can be divided into subcategories to explain schizophrenia; genetic‚ biochemistry (dopamine hypothesis)‚ brain structure and season of birth explanation. Firstly there’s genetics. This view says some people posses certain genes that predispose them to schizophrenia. However‚ if schizophrenia was totally and always inherited then concordance rates between MZ

The Biological Approach to Unipolar Depression. Katie Evans Abnormal behaviour was once thought to be caused by supernatural possession; this demonological model of abnormality was especially popular in the Middle Ages. It was not until the 18th century that psychologists began to argue that this behaviour should be treated as an illness and medical techniques could be used to treat it; and so emerged the medical model of abnormality.
