Age Differences in the Big Five Across the Life Span: Evidence from Two National Samples

Age Differences in the Big Five Across the Life Span: Evidence from Two National Samples | Forming personality-Aspect 2 |

"There are five broad domains" that show the main personality traits. One is extraversion which means these type of people are energetic and sociable. Another is agreeableness which includes being considerate and kind. Another isCconscientiousness which means your hard working and orderly. ANother is Neuroticism which includes being nerovus and tense. And the last is openness which is being creative and artisitc. It's been shown that after the age of 30, extraversion declines while agreeableness increased. These two change the most in your life.

There are two main reasons for major changes in personality. One being maturing and the other is aging. After age 70, many show neuroticism. These are just five broad topics. There is also other versions that use different scales for personalities that are more narrow such as the big five inventory. They use the acronym OCEAN when they talk about these domains

There was a study done within women with alcohol use abuse and those without it. It was shown that there was lower blood oxygen in the brain with those young adults who abuse alcohol. This leads to a decrease in brain activity, so this affects a task that in progress.

Different types of drinking have different affects. Like drinking a little everyday can be harmful, it is better than drinking that same amount at once. Heavy episodic drinking is when those who drink and have hangovers frequently. This causes mainly cognitive impairment. Which is another word for mental disorder.

Also a study that compared "late set" drinking meaning starting to drink after 21 and "early set" drinking mmeaning drinking before age 21, and a control that did not. It showed differences and similarities. It showed in the late set that there was a decreased in blood flow to the frontal lobe. It showed in early set drinking there was a decrease in blood flow. So it shows it does not matter when you start drinking, early set is not more detrimental than late. Heavy drinking greatly damages the brain.

Any type of brain injury with "agnosia" in it, deals with a type of injury that damages knowledge. An example is prosopagnosia which means you can no longer recognize faces.These types mainly affect your consciousness.

In 1930s, psychosurgery was introduced to alter ones state of mind. This allowewd small parts of the brain to be changed. A "cingulotomy" is a type of surgery that was used for patients with a compulsive obsessive disorder such as OCD.In this procedure they would destroy only 2 cm. of white matter. however, there were numerous side effects.

Dopamine is a hormone that produces oxytocin. These are what gives people that love feeling when being with someone you are attracted too or simply thinking of them. Phenylethylamine is released when "you feel bliss." The less oxytocin produced means the lesser or shorter relationships. This hormone is what makes people feel the feeling of being in love.

Interview with a neurology professor from Pitt. His name is Pat Card.

Hi Sarah,

My response to each of your questions follows. However, I also have a general comment. I think your topic is much to broad and that you should narrow it down considerably. One could even subdivide any one of the topics that you have identified into a number of subdivisions. See what you think of my responses and perhaps they will help you settle on a more focal issue.

Does everyone's brain deteriorate over time as they grow older?
Yes. The brain like any tissue deteriorates as individuals age. Typically elderly individuals will become more forgetful and less focused in their thinking as they age. This is normal. Disease processes – e.g., Alzheimer's disease – will dramatically accelerate this decline.

Are there certain brain activities that can make you smarter? Or is it all in genetics?
Even the elderly will benefit by remaining engaged in activities and their environment. There are many studies that have demonstrated that cognitive abilities of aging individuals will decline at a slower rate if they do puzzles and continue activities that engage their intellect. Genetics will certainly influence the intelligence of any individual and is one of the important influences that will determine where an individual scores on an IQ test. However, the young are similar to the elderly in benefiting from mental stimulation and an enriched environment.

Is there really such thing as mind over matter? Can the brain really make you think something isn't there or happening?
Yes, but that typically occurs within the context of mental disorders such as schizophrenia.

How is it possible when we all have the same brain parts, to think and feel differently?
Each individual is the product of their environment. A person's personality is heavily influenced by the experiences that they encounter. For example, the experience of young children (or animals) will influence how they respond to stress as an adult. Children/animals that were exposed to stressful experiences early in development are often hyper-responsive to stress as adults whereas children/animals that are nurtured during the same developmental period are often hypo-responsive to the same stressors.

What effects the brain to make a person's personality? Why are some people depressed and others happy?
Depression is a mental disorder that is due to a mis-regulation of the neurochemicals (a disease process) that allow neurons to communicate. In many instances it is amenable to drug treatment. Variations in personality among healthy individuals is a product of their environment and genes.

What are common brain disorders that you have encountered? Do all these brain disorders cause death?
Not all brain disorders lead to death. People with depression, schizophrenia or a variety of other disorders often lead long lives. Disorders that result in death are generally due to brain trauma, most often to regions that are essential to regulation of critical functions. For example, Christopher Reeve (one of the famous actors who played Superman) fell off a horse and broke his neck. The resulting damage to his spinal cord produced paralysis. However, what ultimately contributed to his death was the damage to the area of his brain that controls breathing.

Is it the brain that controls side effects of drugs and alcohol? Why do people get inversed side effects?
There are specific areas of the brain that reinforce positive experience. These same areas are acted upon by drugs of abuse to produce addiction. Different drugs interact with these systems in different ways, which accounts for the variability in the severity of addiction produced by different drugs.

When does the brain know to change feelings? What chemicals are released for certain emotions?
The brain is constantly integrating input from all of your senses – e.g., vision, hearing, touch, etc. - and comparing it to past experience. This comparison will determine the emotional response. Serotonin is the neurochemical most often associated with emotional state but all of the neurochemicals have some influence.

How and why does the brain perceive illusions and confusions? Is it more of a visual thing or is it the brain?
People who have hallucinations are generally suffering from a mental disorder such as schizophrenia. This is a pathological state that prevents the individual from appropriate interpretation of the stimuli in their environment and accounts for the altered perception. In some cases the hallucinations will be internally generated (e.g., someone hearing voices in their head) by the brain due to this pathology.

If a person is handicapped, in what ways is the brain affected since it controls the body? Is there any damage to the brain then?
It depends upon the type of handicap that the individual is suffering from. Some can be due to disorders of the brain and others to disorders of the body.

My best suggestion for you would be to look for articles on the brain in Scientific American. The magazine often has very informative articles about the brain that are targeted to non-professionals. This will allow you to focus on a specific topic, which will make your task much easier.

A person's personality can be hereditary by being passed down through genes. It also is influenced by the enviorment. A person's surroundings, social groups, ethics, family, friends all influence a persons personality. Personality is a blend of many different traits that make each person unique in their own way.
Sarah Rupchak's comment, March 12, 2013 4:36 PM
Customs and religion have a great influence on a personality. Through this, some are taught different values than others. So because of this, people act a certain way or are to feel a certain way. When a child is devolping their personality, their family has a huge impact. Their social status, class, race, region, job, community all come into play when someone is maturing their personality.
