Thinking Fast Equals Risky Business


Connections between the speed of thought and feelings of euphoria have been reported in cases of clinical mania. New research now links racing thoughts with risk-taking among the general population.

The speed of modern life has increased dramatically in recent decades, and faster is almost always better. But, is that true when it comes to your own thoughts? In two experiments, reported in Psychological Science, scientists manipulated participants’ thought speeds and assessed their appetites for risk. In the first experiment, three dozen students read aloud at different speeds — twice their normal speed or half their normal speed. Then, each student played a computer-simulated game that required them to blow air into a balloon without popping it. Students were rewarded with five cents each time he or she pumped air into the balloon, but lost money each time the balloon popped. The students who had read quickly were more willing to take risks with the balloon (and the money), attempting and achieving more pumps, but also popping more balloons than the students who had read slowly.

In a second experiment, 52 students watched fast-, medium-, or slow-paced movie clips that contained similar content. The students who watched the fast-paced clips reported a greater intention to engage in real-world risky behaviors, including unprotected sex and illegal drug use. Those students were also more likely to minimize the danger associated with each risky behavior.

Previous studies have shown a link between life in the fast-thinking lane and mood. Experimentally accelerated thought is achieved through instructions to brainstorm freely, exposure to multiple ideas, encouragement to plagiarize others’ ideas, performance of easy cognitive tasks, narration of a silent video in fast-forward, and controlled reading speed. Regardless of the types of thoughts that were induced (money-making schemes, word choice, or feelings of depression or elation), individuals demonstrated an increased positive affect after thinking quickly. Increased speed of thought also amplified feelings of power, creativity, and energy, and inflated self-esteem.

Researchers attribute these findings to the subjective experience of thought speed and the joy-enhancing effects of fast thinking. Likewise, thinking slowly is, apparently, a killjoy.

The need for speed is undeniable today’s fast and furious world. But, at what cost? Are we riskier because we are always thinking faster? Or are we happier? Will letting the brain stop and smell the roses decrease our desire to take risks, or will we just become depressed? Human thought is the product of an integrated, sophisticated network that involves neurons, sensory input, and the brain. Speed is fundamental to the thought process, but it is not the only determinant of effectiveness. Efficiency, timing, and appropriateness must be balanced with speed to keep us safe and running smoothly in whatever lane of life’s highway we choose.

7 Ways to Enhance Focus, Creativity, Productivity and Performance

One, it does not require rigid focusing of the mind on one thing for an extended period of time, a practice that most people find extremely difficult.

Two, it appears the benefits can be experienced extremely quickly, in as little as 5-days, and

Three, the practice can be done fairly quickly, allowing almost anyone to fit it into their day.

Wanna jump right in today?

Here’s a simple technique and to get you started with a very basic, accessible 10-minute daily seated practice.

Find a quiet place

Sit in a comfortable upright position with your hands on your knees

Close your eyes and take 10 breaths, letting your exhale get longer and longe with each one

Starting at a very gentle pace, begin to count backwards from 100 by threes, saying each number softly or just sub-lingualizing them with every inhale and exhale. So, for example, inhale and think and say 100, exhale, think and say 97, inhale, think and say 94 and so on. If you get a number wrong, just let it go, say the right one and move one.
When this becomes easy or a few days or week in, pick up the pace a little bit until it becomes easy again. Then, bump the top number by 25 and keep practicing and bumping pace until it gets easy again. Keep at this until the whole practice takes about 20-minutes and give it a few weeks.
Let go of any expectations and see what unfolds...we're all meant to suck at it in the beginning!
There are so many ways to explore AT and access the states that it creates. And, it is important to note that, while the focus of this article is on the "professional" impact of these practice, there is also a very clear and profound impact that reaches deeply into all aspects of your life. That discussion is for a future article.

Does Yawning Cools the Brain??


The medical literature is rife with explanations for yawning, but one has gained substantial ground in recent years: This mysterious habit may help regulate brain temperature.

The brain operates best within a narrow range of temperatures, and like a car engine, it sometimes needs a way to cool down. To lower the brain’s thermostat, researchers say, the body takes in cooler air from its surroundings — prompting deep inhalation.

Yawning is contagious. Simply watching someone do it is enough to induce the behavior. But when scientists had people watch yawning videos in a 2007 study, they found that applying cold packs to the subjects’ heads practically eliminated contagious yawning. Nasal breathing, which also promotes brain cooling, had a similar effect.

In a study of 160 people published last month in the journal Frontiers in Evolutionary Neuroscience, yawning was found to vary by season. People were shown to be more likely to yawn in winter than summer, perhaps because an overheated brain gets little relief from taking in air that is warmer than body temperature.

The researchers, who controlled for factors like humidity and the amount of sleep subjects got the night before, also found that the more time a person spent outside in warm temperatures, the less likely they were to yawn. The findings may explain why people yawn when tired: Sleep deprivation raises brain temperature. As for why yawning is contagious, it may have evolved as a way to signal to others in a group to stay alert and ready in case of outside attacks, scientists say.

THE BOTTOM LINE

Growing evidence suggests yawning may be a way for the brain to cool off, though it is still just a theory.
