Biological Explanation Essay

Biological Biological explanations propose that the criminal behavior is the result of the individual’s defective biological makeup. Neurological abnormalities have been the central focus in studies examining criminal behavior. In one particular study (Raine et al., (2002) – Brain Dysfunction), the brains of convicted murderers, who all pled not guilty by reason of insanity, were compared to those of a control group. The conclusive results showed that the murderers had “reduced activity in areas

A Comparison of Biological and Psychological Explanations of Schizophrenia Both the biological and the psychological explanations of schizophrenia are supported by empirical evidence which justify their explanations. However ,within the biological explanation there is the genetic explanation which is used largely based on scientific research such as that of Gottesman’s research using meta-analysis which looked at the family (including twin) relationships and concordance

Discuss issues of reliability and validity associated with the classification and diagnosis of phobic disorders (24 marks) The biological explanation for the acquisition of phobic disorders establishes that phobias are caused by genetics, innate influences and the principles of biochemistry. This theory recognizes that an oversensitive fear response may be inherited, causing abnormal levels of anxiety. This is illustrated in the basis of inheritance, particularly the adrenergic theory that convicts

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

Biological explanations for anorexia nervosa Biological explanations for anorexia nervosa include neural explanations and evolutionary explanations. 1st BIOLOGICAL EXPLANATION - Neurotransmitters -Serotonin Disturbances in the levels of the neurotransmitter serotonin appear to be a characteristic of individuals with eating disorders. Kaye 2005 found a reduction in the levels of the serotonin metabolite 5-HIAA in people with eating disorders. This suggests that brain serotonin pathways are underactive

Biological Explanation for Anorexia Nervosa Evidence for a faulty gene. AIMS: to see if concordance rates for anorexia are higher in MZ twins compared to DZ twins. This would provide evidence for a faulty gene causing the disorder because if one MZ twin develops anorexia, there should be 100% concordance (agreement) with the second MZ twin also suffering from it, since they share the same genes. The rates

Two Biological Explanations of Schizophrenia There are many biological explanations of schizophrenia. In this essay I will concentrate on the genetic explanation and biochemical explanation of the disorder. There are many studies that look in to genetics and the link to schizophrenia. This is dues to an original finding that schizophrenia runs in families and therefore suggests that genes are responsible for the disorder. I study was preformed by Janicak et al 2001;

and is a subject I regard as important as it can lead to direct improvements to our society, such as reducing crime rates. In particular, the nature verses nurture debate holds great interest to myself, as reading through different biological and social explanations of criminal behaviour highlights the value this debate has in our society. Although psychology is part of everyday life, I find this particular debate important as it attempts to determine whether or not a particular behaviour is a result

to escape or avoid the feelings. A person who experiences learned helplessness usually fails to learn or accept "escape" or "avoidance" in new situations where such behavior would likely be effective. This results in the person giving up. Biological explanation of disordered mood focus on the effects of chemicals on the brain. Scientists have identified genes that make individuals more vulnerable to low moods and influence how an individual responds to drug therapy. Social cognitive theorists believe

Psychology Essay The biological approach suggests that AN is due a physical cause, suggesting it could be due to something within the body or brain; such as hypothalamus dysfunction or an imbalance of neurotransmitters. The hypothalamus dysfunction theory would suggest that animals have a “set weight” which is correct for their body, if this weight should increase or decrease then the body should make adjustments to regulate food intake to their “set weight”. The hypothalamus is thought to have
