นักจิตวิทยาสหรัฐฯพบเคล็ดว่า หากชูกำปั้นขวา กัดฟัน จะช่วยจำความได้แม่นยำ และหากต้องการจะนึกให้ออก ก็ให้ทำซ้ำแบบเดียวกัน แต่เปลี่ยนเป็นชูกำปั้นซ้าย

หัวหน้านักวิทยาศาสตร์ ของมหาวิทยาลัยรัฐมอนต์แคลร์ เปิดเผยว่า ในการทดลองกับผู้ใหญ่เต็มตัว 50 คน ต่างสามารถจำรายการยาวๆ ได้แม่น เมื่อทำแบบนี้ คิดว่า เป็นเพราะการชูกำปั้นได้ไปกระตุ้นสมองส่วนการจดจำขึ้น

หัวหน้านักวิทยาศาสตร์ ดร.รูธ ปรอปเปอร์ กล่าวแจ้งว่า ได้ทราบจากการวิจัยว่า การเคลื่อนไหวของร่างกายง่ายๆ ก็สามารถจะกระตุ้นความจำขึ้นได้ชั่วคราว “จงชูหมัดขวา เมื่อได้เรียนรู้เรื่องใดขึ้นทันควัน และให้ชูหมัดซ้าย เมื่อจะนึกถึงเรื่องอันใดขึ้น”

เคยมีการวิจัยพบว่า การชูกำปั้นขวาเป็นการกระตุ้นสมองซีกซ้าย  ขณะเดียวกัน เมื่อชูกำปั้นซ้ายก็จะไปกระตุ้นสมองซีกขวา การทำเช่นนี้ยังเกี่ยวโยงกับอารมณ์ด้วย เช่น การชูหมัดขวา จะเกี่ยว ข้องกับอารมณ์ความสุข หรือความโกรธ ส่วนหมัดซ้ายจะเกี่ยวพันกับความเสียใจหรือกระวนกระวาย.

Clenching the fist temporarily changes brain function

Clenching the fist temporarily changes brain function

Clenching fists ‘can improve memory’

By Helen Briggs
BBC News

Memory can be improved simply by clenching the fists, a study suggests.

Clenching the right hand for 90 seconds helps in memory formation, while the same movement in the left improves memory recall, say US psychologists.

In an experiment, 50 adults performed better at remembering words from a long list when they carried out these movements.

The researchers think clenching a fist activates specific brain regions that are associated with memory processing.


The experiment

  • 50 right-handed students were given a list of words to learn
  • They were divided into five groups
  • One group clenched their right fist for about 90 seconds before memorising the list and then did the same before recollecting the words
  • A second group carried out the same test, but with the left hand
  • Two other groups clenched one hand prior to learning the words (either the left or right hand) and the opposite hand prior to recollecting
  • A control group did not clench their fists at all
  • The group that clenched their right fist when memorising the list and then clenched the left when recollecting the words performed better than all the other hand clenching groups
  • This group also did better than the group that did not clench their fists at all, though this difference was not statistically ‘significant’.

Lead scientist Ruth Propper, of Montclair State University, Montclair, New Jersey, said the research suggests simple body movements can improve memory by temporarily changing the way the brain functions.

“Clenching your right hand immediately prior to learning information and clenching your left hand immediately before recalling it would be helpful to improve memory,” Dr Propper told BBC News.

Past research has shown that right hand clenching activates the left hemisphere of the brain, while left hand clenching activates the right hemisphere.

This has been associated with emotions – for example right hand clenching with happiness or anger, and left hand clenching with sadness or anxiety.

Memory processing is thought to use both sides of the brain – the left for encoding memories and the right for retrieving them.

Future research will examine whether hand clenching can also improve other mental processes, for example verbal or spatial abilities, and memory of pictures and places, as well as words.

However, more work needs to be done in more subjects to be certain of the results.

Prof Neil Burgess, of University College London Institute of Cognitive Neuroscience, said a larger study was needed to be certain of a specific effect on memory.

This should include brain scans to look at blood flow to the left or right hemispheres of the brain.

Commenting on the study, published in the journal PLOS ONE, he said: “Ideally replication would use a more powerful design (i.e. more people or a within-subjects design) and include fMRI (functional magnetic resonance imaging to measures brain activity) verification of the effect on blood flow.”

Is this the world’s happiest man? Brain scans reveal French monk has ‘abnormally large capacity’ for joy – thanks to meditation

  • Brain scans reveal Buddhist monk Matthieu Ricard has largest capacity for happiness ever recorded
  • Meditation ‘completely changes your brain and therefore changes what you are’, says 66-year-old
  • He says you can do it too by learning how to let your thoughts drift

Ricard: ‘Meditation is not just blissing out under a mango tree but it completely changes your brain’

A French genetic scientist may seem like an unusual person to hold the title – but Matthieu Ricard is the world’s happiest man, according to researchers.

The 66-year-old turned his back on Parisian intellectual life 40 years ago and moved to India to study Buddhism. He is now a close confidante of the Dalai Lama and respected western scholar of religion.

Now it seems daily meditation has had other benefits – enhancing Mr Ricard’s capacity for joy.

Neuroscientist Richard Davidson wired up the monk’s skull with 256 sensors at the University of Wisconsin as part of research on hundreds of advanced practitioners of meditation.

The scans showed that when meditating on compassion, Ricard’s brain produces a level of gamma waves – those linked to consciousness, attention, learning and memory – ‘never reported before in the neuroscience literature’, Davidson said.

The scans also showed excessive activity in his brain’s left prefrontal cortex compared to its right counterpart, giving him an abnormally large capacity for happiness and a reduced propensity towards negativity, researchers believe.

Research into the phenomenon, known as “neuroplasticity”, is in its infancy and Ricard has been at the forefront of ground-breaking experiments along with other leading scientists across the world.

‘We have been looking for 12 years at the effect of short and long-term mind-training through meditation on attention, on compassion, on emotional balance,’ he said.

‘We’ve found remarkable results with long-term practitioners who did 50,000 rounds of meditation, but also with three weeks of 20 minutes a day, which of course is more applicable to our modern times.’

He added to AFP: ‘It’s a wonderful area of research because it shows that meditation is not just blissing out under a mango tree but it completely changes your brain and therefore changes what you are.’

He believes meditation can alter the brain and improve people’s happiness in the same way that lifting weights puts on muscle.

The son of philosopher Jean-Francois Revel and abstract watercolour painter Yahne Le Toumelin, became something of a celebrity after writing ‘The Monk And The Philosopher’ with his father. This was a dialogue on the meaning of life.

He followed up with a practical guide in 2011 called ‘The Art Of Meditation’ making the case for why others should follow the same path.

Matthieu Ricard is a close confidante of the Dalai Lama

Ricard said: ‘That was the end of my quiet time because it was a bestseller. Suddenly I was projected into the western world. Then I did more dialogues with scientists and the whole thing started to spin off out of control.

‘I got really involved in science research and the science of meditation.’

A prominent monk in Kathmandu’s Shechen Monastery, Ricard divides his year between isolated meditation, scientific research and accompanying the Dalai Lama as his adviser on trips to French-speaking countries and science conferences.

He addressed the World Economic Forum in Davos at the height of the financial crisis in 2009 to tell gathered heads of state and business leaders it was time to give up greed in favour of “enlightened altruism”.

He was awarded the French National Order of Merit for his work in preserving Himalayan culture but it is his work on the science of happiness which perhaps defines him best.

Ricard sees living a good life, and showing compassion, not as a religious edict revealed from on high, but as a practical route to happiness.

‘Try sincerely to check, to investigate,’ he said.

‘That’s what Buddhism has been trying to unravel – the mechanism of happiness and suffering. It is a science of the mind.’

MATTHIEU RICARD ON WHY YOU SHOULD MEDITATE AND HOW YOU CAN DO IT

Mattieu Ricard has spoken about The Art of Meditation in a video hosted by the charity RSA. Here are some hints and tips…

  • A healthy mind should act like a mirror – faces can be reflected in a glass but none of them stick. Use the same technique with thoughts – let them pass through your mind but don’t dwell.
  • It’s impossible to stop thoughts from coming but focusing on a particular sound or the breath going in and out calms the mind, giving greater clarity. Controlling the mind is not about reducing your freedom, it’s about not being a slave to your thoughts. Think of it as directing your mind like a boat rather than drifting.
  • Be mindful – pay attention to the sensations of your breath going in and out. If you notice your mind wandering simply bring it back to focusing on your breath. This is known as mindfulness. You can apply it to other sensations to bring you into the ‘now’ rather than dwelling on the past or future. You could focus instead  on heat, cold and sounds that you hear.
  • Once you’ve achieved some skill in this you can use that to cultivate qualities such as kindness, or dealing with disturbing emotions. He says everyone has felt all-consuming love but usually it lasts for about 15 seconds, but you can hold on and nurture this vivid feeling by focusing on it in meditation. If you feel it becoming vague you can consciously revive it.
  • Like when playing the piano, practising the feeling for 20 minutes has a far greater impact over time than a few seconds.  Regular practise is also needed like watering a plant.
  • You can then use meditation to gain some space from negative emotions. Ricard says: ‘You can look at your experience like a fire that burns. If you are aware of anger you are not angry you are aware. Being aware of anxiety is not being anxious it is being aware.’ By being aware of these emotions you are no longer adding fuel to their fire and they will burn down.
  • You will see benefits in stress levels and general wellbeing as well as brain changes with regular practise in a month. Those who say they don’t have enough time to meditate should look at the benefits: ‘If it gives you the resources to deal with everything else during the other 23 hours and 30 minutes, it seems a worthy way of spending 20  minutes,’ Ricard says.

ความสุข ไม่ใช่โอสถใช้รักษาโรค หากเป็นรากฐานของการมีอายุยืน

วารสารทางวิชาการ “การศึกษาเรื่องของความสุข” ของสหรัฐฯ สรุปผลว่า ความสุขไม่ใช่ยารักษาโรค แต่ป้องกันไม่ให้เจ็บไข้ได้ป่วยได้ ด้วยเหตุนั้นความสุขจึงเป็นเหตุให้คนอายุยืน

นักวิจัยอเมริกันได้สรุปด้วยการศึกษาวิเคราะห์ รายงานผลศึกษาติดตามต่าง ๆ รวม 30 เรื่องด้วยกัน

รายงานกล่าวว่า การศึกษาส่วนใหญ่จะกล่าวถึงว่า ผู้ที่มีความสุขจะมีอายุยืน แต่ไม่ทราบได้แน่ว่าความสุขจะทำให้อายุยืนมากน้อยเท่าใด เพราะเหตุว่าการมีสุขภาพดีช่วยได้ทั้งเกิดมีความสุขและความมีอายุวัฒนะ

การศึกษายังพบว่า ความสุขไม่อาจจะช่วยยืดชีวิตให้กับคนไข้หนักได้ แต่ทำให้คนปกติมีอายุยืน ดูเหมือนความสุขจะช่วยป้องกันการล้มเจ็บป่วยได้ สาเหตุที่อยู่เบื้องหลังอย่างหนึ่งก็คือ การขาดความสุขเรื้อรัง ก่อให้เกิดความเครียด ซึ่งจะบ่อนทำลายภูมิคุ้มโรคให้อ่อนแอลง.

Happiness Improves Health and Lengthens Life, Review Finds

ScienceDaily (Mar. 1, 2011) — A review of more than 160 studies of human and animal subjects has found “clear and compelling evidence” that — all else being equal — happy people tend to live longer and experience better health than their unhappy peers.

The study, in the journal Applied Psychology: Health and Well-Being, is the most comprehensive review so far of the evidence linking happiness to health outcomes. Its lead author, University of Illinois professor emeritus of psychology Ed Diener, who also is a senior scientist for the Gallup Organization, of Princeton, N.J., analyzed long-term studies of human subjects, experimental human and animal trials, and studies that evaluate the health status of people stressed by natural events.

“We reviewed eight different types of studies,” Diener said. “And the general conclusion from each type of study is that your subjective well-being — that is, feeling positive about your life, not stressed out, not depressed — contributes to both longevity and better health among healthy populations.”

A study that followed nearly 5,000 university students for more than 40 years, for example, found that those who were most pessimistic as students tended to die younger than their peers. An even longer-term study that followed 180 Catholic nuns from early adulthood to old age found that those who wrote positive autobiographies in their early 20s tended to outlive those who wrote more negative accounts of their young lives.

There were a few exceptions, but most of the long-term studies the researchers reviewed found that anxiety, depression, a lack of enjoyment of daily activities and pessimism all are associated with higher rates of disease and a shorter lifespan.

Animal studies also demonstrate a strong link between stress and poor health. Experiments in which animals receive the same care but differ in their stress levels (as a result of an abundance of nest mates in their cages, for example) have found that stressed animals are more susceptible to heart disease, have weaker immune systems and tend to die younger than those living in less crowded conditions.

Laboratory experiments on humans have found that positive moods reduce stress-related hormones, increase immune function and promote the speedy recovery of the heart after exertion. In other studies, marital conflicts and high hostility in married couples were associated with slow wound healing and a poorer immune response.

“I was almost shocked and certainly surprised to see the consistency of the data,” Diener said. “All of these different kinds of studies point to the same conclusion: that health and then longevity in turn are influenced by our mood states.”

While happiness might not by itself prevent or cure disease, the evidence that positive emotions and enjoyment of life contribute to better health and a longer lifespan is stronger than the data linking obesity to reduced longevity, Diener said.

“Happiness is no magic bullet,” he said. “But the evidence is clear and compelling that it changes your odds of getting disease or dying young.”

“Although there are a handful of studies that find opposite effects,” Diener said, “the overwhelming majority of studies support the conclusion that happiness is associated with health and longevity. Current health recommendations focus on four things: avoid obesity, eat right, don’t smoke, and exercise. It may be time to add ‘be happy and avoid chronic anger and depression’ to the list.”
