    Our top 12 stories of 2014. #9: When a man was fitted with a new heart, his mind changed in unusual ways. Why? The answer reveals a surprising truth about all our bodies, says David Robson. Every second or so, Carlos would feel a small “bump” hitting his tummy. It was the beating of his “second heart”. The small mechanical pump was meant to relieve the burden of his failing cardiac muscles, but Carlos (not his real name) disliked the sensation. The beat of the machine seemed to replace his pulse, a sensation that warped his body image: as the...

    Credit: The Alex Foundation Alex, an African grey parrot who died 5 years ago and was known for his ability to use English words, also understood a great deal about numbers. In a new study in this month's Cognition, scientists show that Alex correctly inferred the relationship between cardinal and ordinal numbers, an ability that has not previously been found in any species other than humans. After learning the cardinal numbers—or exact values—of one to six, Alex was taught the ordinal values (the position of a number in a list) of seven and eight—that is, he learned that six...

    ScienceDaily (Dec. 12, 2011) — New research published December 8 in the journal Science suggests it may be possible to use brain technology to learn to play a piano, reduce mental stress or hit a curve ball with little or no conscious effort. It's the kind of thing seen in Hollywood's "Matrix" franchise. Experiments conducted at Boston University (BU) and ATR Computational Neuroscience Laboratories in Kyoto, Japan, recently demonstrated that through a person's visual cortex, researchers could use decoded functional magnetic resonance imaging (fMRI) to induce brain activity patterns to match a previously known target state and thereby improve performance...

    WINSTON-SALEM, N.C... Smoking marijuana affects peoples’ impulsivity, attention, memory, cognition and decision-making abilities. That’s been scientifically proven. Recent research from Wake Forest Baptist Medical Center draws on the findings of previously published studies to further understanding about how marijuana affects the brains of chronic users, with specific focus on how the drug affects the decision-making process. These findings are important because they demonstrate a potential, negative side effect of chronic marijuana use. “Understanding how marijuana influences the perception of what is ‘negative’ may help explain continued marijuana use and aid in the development of effective strategies for treatment therapies,” said...

    Actively recalling information from memory beats elaborate study methodsPut down those science text books and work at recalling information from memory. That's the shorthand take away message of new research from Purdue University that says practicing memory retrieval boosts science learning far better than elaborate study methods. "Our view is that learning is not about studying or getting knowledge 'in memory,'" said Purdue psychology professor Jeffrey Karpicke, the lead investigator for the study that appears today in the journal Science. "Learning is about retrieving. So it is important to make retrieval practice an integral part of the learning process." Educators...

    SAN FRANCISCO — Maybe it’s time to retire the “senior moment.” These lapses of memory during everyday life — losing your keys or your train of thought — are thought to be more common in older people. Not so, researchers from the University of Waterloo in Canada report March 21 at the annual meeting of the Cognitive Neuroscience Society. Researcher Amanda Clark and her colleagues surveyed 30 adults younger than 25 and 24 people ages 60 to 80 to find out how many slips they make each day. The researchers also devised two lab tests to study attention. One involved...

    Mental powers start to dwindle at 27 after peaking at 22, marking the start of old age, US research suggests. Professor Timothy Salthouse of Virginia University found reasoning, speed of thought and spatial visualisation all decline in our late 20s. Therapies designed to stall or reverse the ageing process may need to start much earlier, he said. His seven-year study of 2,000 healthy people aged 18-60 is published in the journal Neurobiology of Aging. To test mental agility, the study participants had to solve puzzles, recall words and story details and spot patterns in letters and symbols. The same tests...

Regardless, many pundits agreed that as an African-American, Obama could discuss race in ways few white people would dare. That's because most white Americans today have learned not to talk about race for fear of seeming racist, says Samuel Sommers, a social psychologist at Tufts University...

    THIS drug is peddled on every street corner in America, and is found in every country in the world. It is psychoactive, a stimulant and addictive. Users say that it increases alertness and focus, and reduces fatigue. But the high does not last and addicts must keep consuming it in increasing quantities. Put this way, sipping coffee sounds more like an abomination than the world's most accepted form of drug abuse. But centuries of familiarity have put people at their ease. In the coming years science is likely to create many novel drugs that boost memory, concentration and planning. These...

    A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth. Until now, it had been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience — what psychologists call fluid intelligence — is innate and cannot be taught (though people can raise their grades on tests of it by practicing). But in the new study, researchers describe a method for improving this skill, along with experiments to prove it works. The key, researchers found, was...

    Science Daily — The human and chimpanzee genomes vary by just 1.2 percent, yet there is a considerable difference in the mental and linguistic capabilities between the two species. A new study showed that a certain form of neuropsin, a protein that plays a role in learning and memory, is expressed only in the central nervous systems of humans and that it originated less than 5 million years ago. The study, which also demonstrated the molecular mechanism that creates this novel protein, will be published online in Human Mutation, the official journal of the Human Genome Variation Society.

    Amazonian hunter-gatherers who lack written language and who have never seen a math book score highly on basic tests of geometric concepts, researchers said on Thursday in a study that suggests geometry may be hard-wired into the brain. Adults and children alike showed a clear grasp of concepts such as where the center of a circle is and the logical extension of a straight line, the researchers report in this week's issue of the journal Science. Stanislas Dehaene of the College de France in Paris and colleagues tested 14 children and 30 adults of an Amazonian group called the Munduruku,...

    n new studies, scientists find that the maternal instinct is as much biological as it is social and that early socialization through maternal bonding is critical to offsprings' later adjustment. Among new findings: Motherhood helps learning and memory, which in turn helps mothers better care for their offspring. Mothers respond better to cries of their own infants than do fathers. The earlier the stress caused by maternal separation, the greater the offspring's later social difficulties. Nurturing through touch can lessen some of the negative effects of early stress. “Understanding the mechanisms at work in parenting and the effects of disruptions...

Curiously, this clandestine activity does not exist in the youngest brains, leading scientists to believe that the mysterious goings-on that absorb the majority of our minds are dedicated to subconsciously reprocessing our initial thoughts and experiences....

    A few months before retiring from public office in 2002, the House majority leader Dick Armey caused a mini-scandal when he announced during a speech in Florida, ''Liberals are, in my estimation, just not bright people.'' The former economics professor went on to clarify that liberals were drawn to ''occupations of the heart,'' while conservatives favored ''occupations of the brain,'' like economics or engineering. The odd thing about Armey's statement was that it displayed a fuzzy, unscientific understanding of the brain itself: our most compassionate (or cowardly) feelings are as much a product of the brain as ''rational choice'' economic...
