Those attached to the phone are likely to be less happy than those who can resist a ring or a message alert, says a study

If you are constantly on your mobile phone, most onlookers might think you have lots of friends and a busy social life.

However, those attached to the phone are likely to be less happy than those who can resist a ring or a message alert, says a study.

Avid mobile phone users also suffer from higher anxiety while students see their class work suffer with lower marks than those who are able to switch off.

Step away from your camera phone: Constantly taking photographs STOPS our brains remembering what happened

Image
© Atlantide Phototravel/CorbisThis phenomenon has been dubbed 'photo-taking impairment effect.' If the participants took a photo of each object as a whole, they remembered fewer objects and fewer details. The researchers claim the findings highlight key differences between a person's memory and the camera's 'memory'


Taking a photo may seem like the most obvious way to remember a special occasion, but it could in fact be causing significant damage to your memory.

Researchers from Connecticut asked a group of students to recall what items in a museum looked like.

Those who had taken photos of the artefacts struggled to describe the objects, while those who hadn't, remembered them more clearly.

Dr Linda Henkel, from Fairfield University, who ran the study, calls this phenomenon 'photo-taking impairment effect'.

Dr Henkel is currently investigating whether the content of a photo, such as whether a person is in it, for example, affects memory.

Experiencing hardship is GOOD for you: People who have pulled through hard times are happier in the long-run

Image
© Hero Images/Corbis.Researchers presented adults with six positive scenarios, which included going on a hike (pictured) or looking at a waterfall and found those that had endured hardships were able to savour present pleasures more easily.

The most painful experiences in life may come with an eventual upside, by promoting the ability to appreciate life's small pleasures, scientists have said.

A new study suggests that people who have gone through divorce and coped with the death of a loved one, are better equipped to enjoy the little things in everyday life in the long-run.

A total of 14,986 adults were studied to see whether their exposure to life's hardships affected their ability to enjoy positive experiences.

Researchers from the University of British Columbia and Barcelona School of Management, Universitat Pompeu Fabra, Barcelona, first determined participants' exposure to painful experiences, including bereavement and divorce.

Thinking outside the hourglass

This imposed artificial time constraint is a very subtle one, especially when you realize everything depends on perspective. We're clearly experiencing a manipulated, illusory cycle of time with parameters that make us feel contained, limited. And that's the intent. Closing in on your prey is an ingrained predatory behavior. If the subjects feel there's no escape, compliant behavior will eventually follow.

That's pretty clever on the part of the controllers, but it's only effective when you're not awake to what's going on.

Perceived containment has been proven time and again in even popular science to produce certain behaviors. Time is only one factor, but an important one as it is one of the more subtle ways they exert control and amplify fear. We cannot succumb to any of these false paradigms. Humanity is running to and fro in an effort to find solutions, but only within the confines they've been cleverly restricted to. It's a closed system with clearly defined limitations. We look within their constructed time-framed and otherwise controlled system for solutions when there are none to be found. And again, it's all by design.

The only true solution lies in conscious, transcendent awareness of the true big picture.

Playing By the Rules

Herein lies the big "catch". Similar to the obvious political right-left paradigm, we've been injected into a much more complex set of confining rules and regulations. They are adopted by assumption from the parameters we've been given. It's not possible to objectively discern our condition when we think we have all the information we need to make right decisions...when in reality we don't.

Why it's time for brain science to ditch the 'Venus and Mars' cliche

male & female brains

Reports trumpeting basic differences between male and female brains are biological determinism at its most trivial, says the science writer of the year

As hardy perennials go, there is little to beat that science hacks' favourite: the hard-wiring of male and female brains. For more than 30 years, I have seen a stream of tales about gender differences in brain structure under headlines that assure me that from birth men are innately more rational and better at map-reading than women, who are emotional, empathetic multi-taskers, useless at telling jokes. I am from Mars, apparently, while the ladies in my life are from Venus.

How Plato's 'The Republic' describes today's society

Plato
© wikipedia
The Republic (Greek: Πολιτεία, Politeia) is a Socratic dialogue, written by Plato around 380 BC, concerning the definition of justice and the order and character of the just city-state and the just man. It is Plato's best-known work and has proven to be one of the most intellectually and historically influential works of philosophy and political theory. In it, Socrates along with various Athenians and foreigners discuss the meaning of justice and examine whether or not the just man is happier than the unjust man by considering a series of different cities coming into existence "in speech", culminating in a city (Kallipolis) ruled by philosopher-kings; and by examining the nature of existing regimes. The participants also discuss the theory of forms, the immortality of the soul, and the roles of the philosopher and of poetry in society.

In The Republic Plato describes four types of government - monarchy, oligarchy, tyranny, and democracy. The Allegory of the Cave is a discussion on human mentality and the body politic, our thinking and being. There are four types of people in the cave, though nowhere in the text are the characters overtly counted. In the cave there are the captors and captives. The captives in the cave are controlled and know nothing in life but the cave, worse they only know one wall of the cave. The captors use a fire to cast shadows on the wall the prisoners face to keep them captivated and distracted by a made up reality. Among the captives there are the chained and the unchained. The chained are held in place so that they can only look straight ahead and are convinced of the reality and moreover importance of the shadows. The unchained are transfixed with the images and convinced of the reality and moreover the importance of the shadows to the point they don't need chains. They are held by shadows, like elephants onto a string. Both the chained and unchained captives have no interest in their actual existence as captives in a cave. They are not conscious, they are not aware of self or their surroundings, or the captors, they are only aware of and concerned with the shadows.

The brain releases opioids to ease social pain

brain study
© University of MichiganThis is a brain image showing in orange/red one area of the brain where the natural painkiller (opioid) system was highly active in research volunteers who are experiencing social rejection. This region, called the amygdala, was one of several where the U-M team recorded the first images of this system responding to social pain, not just physical pain. Studying this response, and the variation between people, could aid understanding of depression and anxiety.
"Sticks and stones may break my bones, but words will never hurt me," goes the playground rhyme that's supposed to help children endure taunts from classmates. But a new study suggests that there's more going on inside our brains when someone snubs us -- and that the brain may have its own way of easing social pain. The findings, recently published in Molecular Psychiatry by a University of Michigan Medical School team, show that the brain's natural painkiller system responds to social rejection -- not just physical injury.

What's more, people who score high on a personality trait called resilience -- the ability to adjust to environmental change -- had the highest amount of natural painkiller activation.

The team, based at U-M's Molecular and Behavioral Neuroscience Institute, used an innovative approach to make its findings. They combined advanced brain scanning that can track chemical release in the brain with a model of social rejection based on online dating. The work was funded by the U-M Depression Center, the Michigan Institute for Clinical and Health Research, the Brain & Behavior Research Foundation, the Phil F Jenkins Foundation, and the National Institutes of Health.

They focused on the mu-opioid receptor system in the brain -- the same system that the team has studied for years in relation to response to physical pain. Over more than a decade, U-M work has shown that when a person feels physical pain, their brains release chemicals called opioids into the space between neurons, dampening pain signals.

Behaviour can be affected by events in previous generations and passed on through genetic memory

Image
Behaviour can be affected by events in previous generations which have been passed on through a form of genetic memory, animal studies suggest.

Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations.

A Nature Neuroscience study shows mice trained to avoid a smell passed their aversion on to their "grandchildren".

Experts said the results were important for phobia and anxiety research.

The animals were trained to fear a smell similar to cherry blossom.

The team at the Emory University School of Medicine, in the US, then looked at what was happening inside the sperm.

They showed a section of DNA responsible for sensitivity to the cherry blossom scent was made more active in the mice's sperm.

Both the mice's offspring, and their offspring, were "extremely sensitive" to cherry blossom and would avoid the scent, despite never having experienced it in their lives.

Changes in brain structure were also found.

Root causes of dyslexia unraveled

Dyslexia
© Bart BoetsThe researchers showed that the functional and structural connection (blue arrow) between frontal (green) and temporal (red-yellow) language areas is impaired in individuals with dyslexia.
Dyslexia, the learning disability that makes reading and processing speech a challenge, may result from problems with brain connectivity, a new study suggests.

Scientists estimate that dyslexia affects more than 10 percent of the world's population. Some hypothesize that in people with dyslexia, the way that speech sounds are represented in the brain is impaired, while others contend that the brains of people with dyslexia represent the sounds correctly, but have trouble accessing them because of faulty brain connections.

Ultimately, understanding the roots of dyslexia could lead to better ways to help people with the disability, the researchers said.

Normally, when people read words or hear spoken language, the brain creates a map to represent the basic sounds in speech, called phonemes. These brain representations have to be robust, for instance, all "b" sounds must map to the same category.

But they must also be distinct, in order to distinguish between similar sounds such as "b" and "d." In the new study, Bart Boets, a clinical psychologist at KU Leuven, in Belgium, and his colleagues used brain imaging to test which hypothesis - flawed sound representations or flawed wiring - best explains dyslexia.

The researchers scanned the brains of 23 adults with dyslexia and 22 adults without the condition as they responded to various speech stimuli. The scientists looked at how accurately the participants' brains mapped sounds to their phonetic representations.

People with dyslexia had intact representations of basic sounds, just as non-dyslexic people did, the scans revealed.

Talk therapy may reverse biological changes in PTSD patients

A new paper published in Biological Psychiatry suggests that cognitive behavioral therapy for posttraumatic stress disorder (PTSD) not only reduces symptoms but also affects the underlying biology of this disorder.

The researchers, led by Dr. Szabolcs Kéri at the National Institute of Psychiatry and Addictions and University of Szeged in Hungary, recruited 39 individuals diagnosed with PTSD to participate in the study. For a comparison group, they also included 31 individuals who had been exposed to trauma, but who did not develop PTSD. The individuals with PTSD then received 12 weeks of cognitive behavioral therapy, whereas the non-PTSD group received no therapy.

Before and after the 12 weeks, the researchers measured the volumes of certain brain regions using magnetic resonance imaging. They also collected blood samples to measure changes in expression of a specific gene, FKBP5, which has been implicated in the risk for developing PTSD and plays a role in regulating stress hormones.
