Closing your eyes when trying to recall events increases the chances of accuracy, researchers at the University of Surrey suggest. Scientists tested people's ability to remember details of films showing fake crime scenes. They hope the studies will help witnesses recall details more accurately when questioned by police.

Our social media activity can give extraordinary - and often unintentional - insights into our mental wellbeing. Little wonder that professionals whose job it is to look after our emotional health are now exploring how they can use these signals to take the 'emotional pulse' of individuals, communities, nations and even the entire species. Apparently, the words that're said are less important than the category or the frequency of posts in re: painting user profiles.

New research suggests it's how parents talk to their infants, not just how often, that makes a difference for language development. Infants whose mothers had shown "sensitive" responses--verbally replied to or imitated the babies' sounds--showed increased rates of consonant-vowel vocalizations, meaning that their babbling more closely resembled something like real syllables, paving the way for real words. The same babies were also more likely to direct their noises at their mothers, indicating that they were "speaking" to them rather than simply babbling for babbling's sake. "The infants were using vocalizations in a communicative way, in a sense, because they learned they are communicative," study author Julie Gros-Louis, a psychology professor at the University of Iowa, said in a statement. In other words, by acting like they understood what their babies were saying and responding accordingly, the mothers were helping to introduce the concept that voices, more than just instruments for making fun noises, could also be tools for social interaction.

Offering a written expression of condolence (from the Latin word condolere, to grieve or to suffer with someone) used to be a staple of polite society. "A letter of condolence may be abrupt, badly constructed, ungrammatical - never mind," advised the 1960 edition of Emily Post. "Grace of expression counts for nothing; sincerity alone is of value." But these days, as Facebooking, Snapchatting or simply ignoring friends has become fashionable, the rules of expressing sympathy have become muddied at best, and concealed in an onslaught of emoji at worst. Just over two and a half million Americans die every year, according to the National Center for Health Statistics, and we buy 90 million sympathy cards annually, a spokeswoman for Hallmark said. But 90 percent of those cards are bought by people over 40. Take-away tips from the article: 1. BEING TONGUE-TIED IS O.K. 2. SHARE A POSITIVE MEMORY 3. NO COMPARISONS 4. DON'T DODGE THE 'D' WORDS 5.

Doctors at Beth Israel Deaconess Medical Center in Boston, Massachusetts, are treating stroke patients who have little or no spontaneous speech by associating melodies with words and phrases. "Music, and music-making, is really a very special form of a tool or an intervention that can be used to treat neurological disorders, said Dr. Gottfried Schlaug, associate professor of neurology at Beth Israel and Harvard University.

Translation is critical for addressing information inequalities in Africa. But could translation also improve economic development, health, human rights, and safety of the citizens of Africa? Findings from a new study reveal that the answer is "yes."

This article is about how a second language may help in your critical thinking process. Because of the unfamiliarity of the language, it may take away taboos or emotions associated with words that may influence our decision.

"They scanned a total of 79 trainees, just before they started to learn the "All-London" Knowledge [memorizing "25,000 streets and 20,000 landmarks and places of interest"], which can take between two and four years to complete. ... those who had attempted the Knowledge had increased the size of the posterior hippocampus - the rear section of the hippocampus which lies at the front of the brain. ... this advantage appeared to come at a price, as the non-cabbies outperformed them in other memory tasks, such as recalling complex visual information."

"...scientists found that different toddler sounds - or "vocalizations" - emerge and fade in a definite rhythm in the course of a tantrum. "We have the most quantitative theory of tantrums that has ever been developed in the history of humankind" ... where one age-old theory of tantrums might suggest that meltdowns begin in anger (yells and screams) and end in sadness (cries and whimpers), Potegal found that the two emotions were more deeply intertwined. ... The trick in getting a tantrum to end as soon as possible, Potegal said, was to get the child past the peaks of anger. Once the child was past being angry, what was left was sadness, and sad children reach out for comfort. The quickest way past the anger, the scientists said, was to do nothing."

"Talking or texting on a phone while walking can make it difficult to stay on course and may interfere with memory recall ... Moreover, participants who were texting while walking veered off course demonstrating a 61 percent increase in lateral deviation and 13 percent increase in distance traveled."

"Web addicts have brain changes similar to those hooked on drugs or alcohol, preliminary research suggests. ... Dr Hao Lei and colleagues write in Plos One: 'Overall, our findings indicate that IAD has abnormal white matter integrity in brain regions involving emotional generation and processing, executive attention, decision making and cognitive control.' ... Prof Gunter Schumann, chair in biological psychiatry at the Institute of Psychiatry at King's College, London, said similar findings have been found in video game addicts. ... further studies with larger numbers of subjects were needed to confirm the findings."

"... one thing is growing increasingly clear to many researchers: The word "cancer" is out of date, and all too often it can be unnecessarily frightening. "Cancer" is used, these experts say, for far too many conditions that are very different in their prognoses ... It is like saying a person has "mental illness" when he or she might have schizophrenia or mild depression or an eating disorder."

New research suggests that 3-month-old human babies can use lemur calls as teaching aids. The findings hint at a deep biological connection between language and learning. But not everyone agrees that the new work shows that primate sounds can stimulate a child's linguistic instinct. "This work tells us that sounds that are more like human language are more effective," says , a psychologist at the University of California, Davis. "What is more controversial is why they are effective." She says it's still unclear whether the primate sounds are stimulating some deep linguistic circuit in the brain or just getting the babies to look.

"You, hear me! Give this fire to that old man. Pull the black worm off the bark and give it to the mother. And no spitting in the ashes!" It's an odd little speech. But if you went back 15,000 years and spoke these words to hunter-gatherers in Asia in any one of hundreds of modern languages, there is a chance they would understand at least some of what you were saying. That's because all of the nouns, verbs, adjectives and adverbs in the four sentences are words that have descended largely unchanged from a language that died out as the glaciers retreated at the end of the last Ice Age. Those few words mean the same thing, and sound almost the same, as they did then. While traditionally, it's been thought that words can't survive for more than 8,000 to 9,000 years, a team of researchers from the University of Reading has come up with a list of two dozen "ultraconserved words" that have survived 150 centuries. It includes some predictable entries: "mother," "not," "what," "to hear" and "man." It also contains surprises: "to flow," "ashes" and "worm." The existence of the long-lived words suggests there was a "proto-Eurasiatic" language that was the common ancestor to about 700 contemporary languages that are the native tongues of more than half the world's people.

It's hard to imagine a more devastating diagnosis than ALS, also called Lou Gehrig's disease. For most people, it means their nervous system is going to deteriorate until their body is completely immobile. That also means they'll lose their ability to speak. Voice banking, a digital technology, allows ALS patients to record their voice and key messages in preparation for that time.

Lin, of National Chung Cheng University, Taiwan and Peper, of San Francisco State University, examined the psychophysiological effects of texting. Results indicated that all subjects showed significant increases in respiration rate, heart rate, SC, and shoulder and thumb SEMG as compared to baseline measures. Eighty-three percent of the participants reported hand and neck pain during texting, held their breath, and experienced arousal when receiving text messages. Subjectively, most subjects were unaware of their physiological changes. The study suggests that frequent triggering of these physiological patterns (freezing for stability and shallow breathing) may increase muscle discomfort symptoms. Thus, participants should be trained to inhibit these responses to prevent illness and discomfort.

We start building our sense of people's personalities from the first words they utter. Phil McAleer, of the University of Glasgow, ran an experiment where he recorded 64 people, men and women, from Glasgow, reading a paragraph that included the word "hello." He then extracted all the hellos and got 320 participants to listen to the different voices and rate them on 10 different personality traits, such as trustworthiness, aggressiveness, confidence, dominance and warmth. Interestingly, participants largely agreed on which voice matched which personality trait. One male voice was overwhelmingly voted the least trustworthy. The pitch of the untrustworthy voice was much lower than the male deemed most trustworthy. McAleer says this is probably because a higher pitched male voice is closer to the natural pitch of a female, making the men sound less aggressive and friendlier than the lower male voices. What makes females sound more trustworthy is whether their voices rise or fall at the end of the word, says McAleer. "Probably the trustworthy female, when she drops her voice at the end, is showing a degree of certainty and so can be trusted." (Perhaps a reason to avoid uptalk, if you're female?)

This study shows the science behind first impressions, and how certain voices can affect first impressions.

John Pennebacker, a University of Texas-Austin psychologist, found that language could successfully predict speed dating successes, as well as the relative longevity of such matches.. When the language style of two people matched, when they used pronouns, prepositions, articles and so forth in similar ways at similar rates, they were much more likely to end up on a date. "The more similar [they were] across all of these function words, the higher the probability that [they] would go on a date in a speed dating context," Pennebaker says. "And this is even cooler: We can even look at ... a young dating couple... [and] the more similar [they] are ... using this language style matching metric, the more likely [they] will still be dating three months from now." This is not because similar people are attracted to each other, Pennebaker says; people can be very different. It's that when we are around people that we have a genuine interest in, our language subtly shifts. "When two people are paying close attention, they use language in the same way," he says. "And it's one of these things that humans do automatically." Pennebacker also says that by analyzing language, you can easily tell who among two people has power in a relationship, and their relative social status. "It's amazingly simple," Pennebaker says, "Listen to the relative use of the word "I." What you find is completely different from what most people would think. The person with the higher status uses the word "I" less.

The human voice appears to trigger pleasure circuits in the brains of typical kids, but not children with autism, a Stanford University team reports. The finding could explain why many children with autism seem indifferent to spoken words. The Stanford team used functional MRI to compare the brains of 20 children who had autism spectrum disorders and 19 typical kids. In typical kids there was a strong connection between areas that respond to the human voice and areas that release the feel-good chemical dopamine, but that connection was reduced in autistic children. Connections between voice areas and areas involved in emotion-related learning also were weaker, creating greater communication difficulties. The new study's suggestion that motivation is the problem could explain why speech often comes late to children with autism even though the brain circuit involved in processing spoken words seems to function normally; the reward circuitry isn't working the way it does in typical children.

Yes, caffeine helps. But new research shows that the moderate noise level in busy cafés also perks up your creative cognition. Global X/ Flickr PROBLEM: To optimize creativity, how quiet or noisy should your workspace be? METHODOLOGY: Researchers led by Ravi Mehta conducted five experiments to understand how ambient sounds affect creative cognition.
