Nature vs. Nurture

Are We Really Born That Way?

By Kimberly Powell, About.com Guide

Jul 19 2010

You got your green eyes from your mother, and your freckles from your

father. But where did you get your thrill-seeking personality and talent for

singing? Did you learn these from your parents or was it predetermined by

your genes? While it's clear that physical characteristics are hereditary, the

genetic waters get a bit more murky when it comes to an individual's

behavior, intelligence, and personality. Ultimately, the old argument of

nature vs. nurture has never really been won. We do not yet know how

much of what we are is determined by our DNA and how much by our life

experience. But we do know that both play a part.

What is Nature vs Nurture?

It has been reported that the use of the terms "nature" and "nurture" as a

convenient catch-phrase for the roles of heredity and environment in human

development can be traced back to 13th century France. Some scientists

think that people behave as they do according to genetic predispositions or

even "animal instincts." This is known as the "nature" theory of human

behavior. Other scientists believe that people think and behave in certain

ways because they are taught to do so. This is known as the "nurture"

theory of human behavior.

Fast-growing understanding of the human genome has recently made it

clear that both sides are partly right. Nature endows us with inborn abilities

and traits; nurture takes these genetic tendencies and molds them as we

learn and mature. End of story, right? Nope. The "nature vs nurture" debate

still rages on, as scientist fight over how much of who we are is shaped by

genes and how much by the environment.

Ten differences between Mens and Womens brains

By Amber Hensley

The differences between women and men are not only well-documented, but

frequently at the heart of jokes, anecdotes, and good-natured (and not so good-

natured) ribbing. Experts have discovered that there are actually differences in the

way women’s and men’s brains are structured and in the way they react to events

and stimuli. So the next time your wife, boyfriend, or parent starts telling you how

you should have done something differently, then refer back to these big

differences between men’s and women’s brains.

1. Human relationships. Women tend to communicate more effectively than men, focusing on how to create a solution that works for the group, talking through issues, and utilizes non-verbal cues such as tone, emotion, and empathy whereas men tend to be more task-oriented, less talkative, and more isolated. Men have a more difficult time understanding emotions that are not explicitly verbalized, while women tend to intuit emotions and emotional cues. These differences explain why men and women sometimes have difficulty communicating and why men-to-men friendships look different from friendships among women.

2. Left brain vs. both hemispheres. Men tend to process better in the left hemisphere of the brain while women tend to process equally well between the two hemispheres. This difference explains why men are generally stronger with left-brain activities and approach problem-solving from a task-oriented perspective while women typically solve problems more creatively and are more aware of feelings while communicating.

3. Mathematical abilities. An area of the brain called the inferior-parietal lobule (IPL) is typically significantly larger in men, especially on the left side, than in women. This section of the brain is thought to control mental mathematical ability, and probably explains why men frequently perform higher in mathematical tasks than do women. Interestingly, this is the same area of Einstein’s brain that was discovered to be abnormally large. The IPL also processes sensory information, and the larger right side in women allows them to focus on, "specific stimuli, such as a baby crying in the night."

4. Reaction to stress. Men tend to have a "fight or flight" response to stress situations while women seem to approach these situations with a "tend and befriend" strategy. Psychologist Shelley E. Taylor coined the phrase "tend and befriend" after recognizing that during times of stress women

take care of themselves and their children (tending) and form strong group bonds (befriending). The reason for these different reactions to stress is rooted in hormones. The hormone oxytocin is released during stress in everyone. However, estrogen tends to enhance oxytocin resulting in calming and nurturing feelings whereas testosterone, which men produce in high levels during stress, reduces the effects of oxytocin.

5. Language. Two sections of the brain responsible for language were found to be larger in women than in men, indicating one reason that women typically excel in language-based subjects and in language-associated thinking. Additionally, men typically only process language in their dominant hemisphere, whereas women process language in both hemispheres. This difference offers a bit of protection in case of a stroke. Women may be able to recover more fully from a stroke affecting the language areas in the brain while men may not have this same advantage.

6. Emotions. Women typically have a larger deep limbic system than men, which allows them to be more in touch with their feelings and better able to express them, which promotes bonding with others. Because of this ability to connect, more women serve as caregivers for children. The down side to this larger deep limbic system is that it also opens women up to depression, especially during times of hormonal shifts such as after childbirth or during a woman’s menstrual cycle.

7. Brain size. Typically, men’s brains are 11-12% bigger than women’s brains. This size difference has absolutely nothing to do with intelligence, but is explained by the difference in physical size between men and women. Men need more neurons to control their greater muscle mass and larger body size, thus generally have a larger brain.

8. Pain. Men and women perceive pain differently. In studies, women require more morphine than men to reach the same level of pain reduction. Women are also more likely to vocalize their pain and to seek treatment for their pain than are men. The area of the brain that is activated during pain is the amygdala, and researchers have discovered that in men, the right amygdala is activated and in women, the left amygdala is activated. The right amygdala has more connections with areas of the brain that control external functions while the right amygdala has more connections with internal functions. This difference probably explains why women perceive pain more intensely than do men.

9. Spatial ability. Men typically have stronger spatial abilities, or being able to mentally represent a shape and its dynamics, whereas women typically struggle in this area. Medical experts have discovered that women have a thicker parietal region of the brain, which hinders the ability to mentally rotate objects–an aspect of spatial ability. Research has shown this ability in babies as young as 5 months old, negating any ideas that these abilities were strengthened by environmental influences.

10. Susceptibility to disorders. Because of the way men and women use the two hemispheres of the brain differently, there are some disorders that men and women are susceptible to in different ways. Men are more apt to have dyslexia or other language problems. If women have dyslexia, they are more likely to compensate for it. Women, on the other hand, are more susceptible to mood disorders such as depression and anxiety. While handedness is not a disorder, these brain tendencies also explain why more men are left-handed than are women. Men are also more likely to be diagnosed with autism, ADHD, and Tourette’s Syndrome.

JOKES - Differences Between Men and Woman

George Carlin Quote

Women are crazy. Men are stupid. The main reason women are crazy is

that men are stupid.

Creation Order Joke

God made man before woman so the man would have time to think of an

answer for the woman's first question.

Men, you may think you have a command of the English language, but

when it comes to communicating with women, you may be surprised.

Here is our dictionary of Womanese. Master these terms and you'll

find your relationship with women greatly improved.

The Real Definition of Words When Used By Women

1. Fine - I am right. This argument is over. You

need to shut up.

2. That's Okay - One of the most dangerous

statements a women can make to a man.

"That's okay" means she wants to think hard

and long before deciding when and how you'll

pay for your mistake.

3. Nothing - The calm before the storm. This means

"Something" and you better be on your toes. Note: Arguments

that start with "Nothing" usually end with "Fine" (See #1).

4. Five Minutes - If getting dressed, this means half an hour.

(Don't be mad about this. It's the same definition for you

when it's your turn to do some chores around the house.)

5. Thanks - A woman is thanking you. Do not question this or

faint. Just say, "You're welcome," and let it go.

6. Loud Sigh - Not actually a word but rather a non-verbal

statement often misunderstood by men. It means she thinks

you are an idiot and wonders why she is standing here wasting

her time arguing with you about "Nothing." (See #3)

7. Go Ahead - This is a dare, not permission. (Don't Do It!)

8. Don't worry about it, I got it - The second most dangerous

statement a woman can make. It means that a woman has

asked a man several times to do something and is now doing it

herself. (This will result in you asking at a later date, "What's

wrong?" For the woman's response, see #3.)

Differences Between Man and Women

Names

If Mary, Susan, Claire and Barbara go out for lunch, they will call each

other Mary, Susan, Claire and Barbara.

If John, Brad, Tony and Daniel go out, they will affectionately refer to

each other as Bruno, Scrappy, Peanut-Head and Godzilla.

Eating Out

When the bill arrives, John, Brad, Tony and Daniel will each throw in

$20, even though the total is only $34.25. None of them will have any

smaller bills and none will admit they want change back.

When Mary, Susan, Claire and Barbara get their bill, out come the

pocket calculators.

Money

A man will pay $10 for a $5 item he needs.

A woman will pay $5 for a $10 item that she doesn't need, because it's

on sale.

Bathrooms

A man has five items in his bathroom: a toothbrush,

razor, shaving cream, a bar of soap, and a towel from

the Motel 6.

The average number of items in a woman's bathroom is 328. The

average man would not be able to identify most of them.

Arguments

Women always have the last word in an argument. Anything a man adds

after that is the beginning of a new argument.

Cats

Women love cats.

Men may say they love cats, but when women are not looking, will men

kick cats.

Future

A woman worries about the future -- until she gets a husband.

A man never worries about the future -- until he gets a wife.

Success

A successful man is one who makes more money than can be spent by

his wife.

A successful woman is one who can find that a man.

Marriage

A woman marries a man expecting he will change, but he doesn't.

A man marries a woman expecting that she won't change, and she does.

Dressing Up

A woman will dress up when she goes shopping, empties the garbage,

answers the phone, waters the plants, gets the mail and reads a book.

A man will dress up for weddings and funerals.

Natural

Men wake up looking as good as when they went to bed.

Women will somehow deteriorate during the night.

Children

A woman knows all about her children. She knows about their best

friends, romances, secret hopes and dreams, favorite foods, fears and

dental appointments.

A man is vaguely aware of some short people living in the house.

Thought for the Day

Married men should forget their mistakes. There is no need for two

people to remember the same thing.

Te Be Six Again

You really have to give this guy an A+ for effort.

George was a thoughtful husband. He wanted to give his wife something

special for her birthday which was coming up soon. As he sat on the

edge of the bed, he watched his wife turning back and forth and

looking at herself in the mirror. "Reta," he said, "What would you like

for your birthday?"

His wife continued to look at herself and said, "I'd like to be six again."

George knew just what to do. On the big day, he got up early and made

his wife a bowl of Fruit Loops. Then he took her to an amusement park

where they rode all the rides. Five hours later, Reta's stomach felt

upside down and her head was reeling. Never the less, George took her

to McDonald's and bought her a Happy Meal with extra fries and a

chocolate shake. Next, it was a movie with popcorn, soda and her

favorite candy.

As Reta wobbled into the house that evening and flopped on the bed,

George asked her, "Well, Dear, what was it like to be six again?"

Reta looked up at him. Her expression changed. She said, "I meant my

dress size!"

Why Men Are Happier

Men can play with toys all their life.

Men can wear shorts no matter what their legs look like.

Men have one wallet and one pair of shoes which are good for every

season.

Men can choose whether or not to grow a mustache.

Men can "do" their fingernails with a pocket knife.

Men's bellies usually hide their large hips.

Chocolate is just another snack.

The whole garage belongs to them.

Weddings take care of themselves.

Men's last name never changes.

Everything on a man's face stays its original color.

Men only have to shave their faces and necks.

Men can keep the same hairstyle for years, even decades.

Men can do their Christmas shopping for 25 relatives on Christmas Eve

in 25 minutes.

For men, wrinkles add character.

Men can go on a week's vacation and pack only one suitcase.

Men's new shoes don't cause blisters, or cut or mangle their feet.

Men don't have to stop and think which way to turn a screw.

Men have one mood all the time.

A wedding dress cost $5000. A tuxedo rental - 100 bucks

Men can open all their own jars.

Other jokes

1. A man will pay $2 for a $1 item he wants. A woman will pay $1 for a $2 item that she doesn't want.

2. A woman worries about the future until she gets a husband. A man never worries about the future until he gets a wife.

3. A successful man is one who makes more money than his wife can spend. A successful woman is one who can find such a man.

4. To be happy with a man you must understand him a lot & love him a little. To be happy with a woman you must love her a lot & not try to understand her at all.

5. Married men live longer than single men - but married men are a lot more willing to die.

6. Any married man should forget his mistakes - there's no use in two people remembering the same thing.

7. Men wake up as good-looking as they went to bed. Women somehow deteriorate during the night.

8. A woman marries a man expecting he will change, but he doesn't. A man marries a woman expecting that she won't change & she does.
