Research has shown that teenagers perceive and process risk differently than adults. When risk is known, they tend to overestimate it, yet they are more likely to engage in activities that have unknown risks, where adults may be more hesitant in those situations.
The part of the brain that deals with analyzing risk is called the neocortex. It is extremely complex, and exists solely in mammals. This more modern, advanced analytical system can often contradict with our more primitive part of the brain that assesses risk: the amygdala.
Many CEOs and successful businesspeople credit their success to risk-taking, and overcoming a fear of failure.
Risk-taking behavior may be linked to a very different characteristic – boredom. Studies have shown that people who report being regularly bored may be more prone to taking risks, but unfortunately these risks may include indulging in drugs or alcohol.
Studies have shown that stockbrokers may have a psychological profile that is more prone to risk-taking than that of psychopaths.
MRI scans have shown that the brain responds to an expectation of an experience in the same way that it responds to an experience that’s already happened – a factor that may encourage us to take a risk.
Studies have shown that people who take more risks have fewer receptors that inhibit dopamine, the brain's feel-good chemical.
Many people think of risk-takers as "adrenaline junkies", when in fact the neurotransmitter, adrenaline, is meant to help us escape danger, not pursue it. When the brain detects a threat, it releases adrenaline into the bloodstream in order to help us flee or fight. This chemical rush can create a feeling of exhilaration, which the so-called "adrenaline-junkies" then may continue to seek out.
We all acclimate to risk over time in our day to day lives. When activities such as learning to drive a car become more familiar to us, our brains adapt to the risk and learn to manage fear.
Due to the hormone testosterone, and the need to compete, men may be more likely to take physical risks than women. However, women are risk takers as well, and may be more likely than men to take social risks, such as changing careers later in life.

Recent research analyzing the sounds in languages spoken around the world points to southern Africa as the place where modern human language originated. Using phonemes, the consonants, vowels, and tones, Dr. Quentin Atkinson found a pattern in some 500 languages spoken throughout the world. He found the further language areas are from South Africa, the fewer phonemes they have. Some of the click-languages of Africa have more than 100 phonemes, English has about 45 phonemes, and Hawaiian only has 13.
Fewer than a thousand people speak a quarter of the world’s languages. If these languages are not passed down through the generations they will disappear. For instance, some three-thousand languages may already disappear by the end of the century.

Altruistic behavior is not unique to humans – examples from the animal kingdom include: some bats “donate” their blood and give it to other members of their group and some bird species help raise young that are not their own.
The part of your nervous system known as the “vagus nerve” starts at the top of the spinal cord and reaches throughout your body. When test subjects are shown images of suffering or distress, this nerve flares with activity. This has led scientists to believe there is a strong connection between this nerve and a person’s capacity for compassion.
While we might be willing to engage in selfless acts for both friends and relatives, our motives for doing so are distinct. One study has found that we help our friends due to empathy and our family due to an expectation of reciprocity.

Swearing, a common reaction to experiencing pain, has been shown to increase tolerance of physical pain by triggering aggression and accelerated heart rate during the body’s natural “fight-or-flight” response.
BATTLE OF THE SEXES
The difference between the male brain and the female brain begins before birth. Using an ultrasound scanner, researchers in a recent study found that the corpus callosum, the bridge of nerve tissue that connects the right and left hemispheres of the brain had a thicker measurement in female fetuses than male fetuses starting at just 26 weeks of pregnancy.
Researchers have found that generally, girls outperform boys when it comes to fine motor skills and use of language until puberty. A study of 508 children ages 2 months to 16 years found that cerebral areas that process these skills develop six years earlier for girls.
A recent study of 508 children ages 2 months to 16 years found the areas of the brain that process special rotation and that are involved in math and geometry mature about four years earlier in boys than in girls.
While male brain volumes are overall larger than women, studies have found that women generally have larger volumes in areas of the brain with emotions and language, while men have larger volumes in areas associated with memory, learning, and survival instincts.
Men and women use two entirely different areas of their brain spatial skills, like navigating directions. Women use the cerebral cortex and men use the left hippocampus to solve navigation puzzles. The hippocampus automatically codes where you are in space, but does not activate in women’s brains for tasks requiring navigation. Men tend to navigate through depth reckoning, i.e. “go north, and then west”, and women tend to mark their way with landmarks.
A recent study confirmed that men’s and women’s brains are wired differently. The right and left hemispheres have a stronger connection in female brains, and the front and back regions are more highly connected in male brains.
Along with different wiring, there are differences in the structure of the male and female brain. Men tend to think with their gray matter, of which their brains have roughly 6.5 times more than female brains. On the other hand, females think with their white matter, of which they have about 10 times more than male brains.
Women’s brains have a more complicated setup than male brains. Recent studies show that this may allow their brains to work more efficiently and more quickly than men’s.
A woman’s pain threshold changes with her estrogen levels. When the brain receives a pain signal, it releases endorphins or enkephalins to help control the pain. When estrogen levels are high, this pain management system works more effectively than when estrogen levels are low. It is part of the reason that women can endure the pain of childbirth.
Several studies suggest that men don’t feel acute pain as intensely as their female counterparts, but a recent study shows found that when it comes to chronic pain, there is no difference in both genders’ experience of pain, mood, or quality of life with the pain.
Intuitive senses combine all natural senses with each person’s own life experience.
According to one experiment some blind people are able to utilize the phenomenon of blindsight. Even though they can’t see, their intuitive vision helps them to navigate throughout life and perceive emotion on a person’s face.

When emotions become involved in decision-making, it is much more difficult for intuition to navigate effectively.
First responders and soldiers in battle must rely on intuition in the heat of the moment to make quick decisions.
Decisions based on intuition are made very quickly. This is possible in part because of previous experiences. Recognizing past experiences helps to make quick decisions.
Intuition is also referred to as the ‘sixth sense.’
Intuitive training is a form of physical training where people listen to their bodies for cues as to how they should work out. People do not subscribe to an intense fitness program, but rather look to their bodies and intuition for guidance.
Meditation can help you stay more in tune with your intuition.
