Researchers scientifically investigate the effect of genetic influence through the use of family and twin studies. These studies, coupled with the recently developed technologies of neuroscience, have led to the fairly solid conclusion that many personality traits i. Coccaro and Siever reviewed many neurobiological research studies and reported their summary conclusions about the neurobiological factors associated with personality disorder.
Saul McLeodupdated The biological approach believes us to be as a consequence of our genetics and physiology. It is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view. Therefore, all that is psychological is first physiological.
A biological perspective is relevant to the study of psychology in three ways: This can help in the search to understand human behavior. For example, we could ask how prescribed drugs to treat depression affect behavior through their interaction with the nervous system.
|Ms Parrot: Essay Chef||Race historical definitions During the Age of Enlightenment an era from the s to the sconcepts of monogenism and polygenism became popular, though they would only be systematized epistemologically during the 19th century. Monogenism contends that all races have a single origin, while polygenism is the idea that each race has a separate origin.|

For example, we might want to know whether high intelligence is inherited from one generation to the next.
Each of these biological aspects, the comparative, the physiological i. Investigation of Inheritance Twin studies provide geneticists with a kind of natural experiment in which the behavioral likeness of identical twins whose genetic relatedness is 1.
In other words, if heredity i. There are two types of twins: Research using twin studies looks for the degree of concordance or similarity between identical and fraternal i. Twins are concordant for a trait if both or neither of the twins exhibits the trait. Twins are said to be disconcordant for a trait if one shows it, and the other does not.
Identical twins have the same genetic make-up, and fraternal twins have just 50 per cent of genes in common. Thus, if concordance rates which can range from 0 to are significantly higher for identical twins than for fraternal twins, then this is evidence that genetics play an important role in the expression of that particular behavior.
Bouchard and McGue conducted a review of worldwide studies which compared the IQ of family members. The correlation figures below represent the average degree of similarity between the two people the higher the similarity, the more similar the IQ scores.
For example, Bouchard and McGue included many poorly performed and biased studies in their meta-analysis. Also, studies comparing the behavior of twin raised apart have been criticized as the twins often share similar environments and are sometimes raised by non-parental family member.
Methods of Studying the Brain It is important to appreciate that the human brain is an extremely complicated piece of biological machinery. The brain can influence many types of behavior. In addition to studying brain damaged patients, we can find out about the working of the brain in three other ways.
Children begin to plan activities, make up games, and initiate activities with others. If given this opportunity, children develop a sense of initiative and feel secure in their ability to lead others and make decisions.
Neuro Surgery We know so little about the brain and its functions are so closely integrated that brain surgery is usually only attempted as a last resort. This technique cured his epilepsy, but in the process the hippocampus had to be removed this is part of the limbic system in the middle of the brain.
So now we know the hippocampus is involved in memory. Electrodes are attached to the scalp and brain waves can be traced.
During this, our brain waves begin to resemble those of our waking state though we are still fast asleep and it seems that this is when we dream whether we remember it or not. Brain Scans More recently methods of studying the brain have been developed using various types of scanning equipment hooked up to powerful computers.Scientific racism (sometimes referred to as race biology, racial biology, or race realism) is the pseudoscientific belief that empirical evidence exists to support or justify racism (racial discrimination), racial inferiority, or racial superiority.
Historically, scientific racist ideas received credence in the scientific community but are no longer considered scientific. The human body is an amazing and very complex organism.

Post Traumatic Stress Disorder and Veterans - This essay discusses Post Traumatic Stress Disorder (PTSD) and its effect on combat soldiers involved in the Afghanistan and Iraq Wars.
Students with a score of 4 or 5 on the AP Biology test may use their AP credit to meet the general education requirement in the Biological Sciences if the first three quarters of the Advanced Biology sequence are completed.
This essay reviews some of the biological factors involved in stress and it has been organized in the following way. The paper begins by briefly introducing the concept of stress.
It will then go on to discus and describe the automatic response (fight or flight reaction), hormonal changes and the effects of cortisol on heart rate, breathing.
