Recent studies suggest that metaphors are more than just fancy literary devices and that there is a psychological basis for linking cold with feelings of social isolation. Psychologists Chen-Bo Zhong and Geoffrey Leonardelli from the University of Toronto's Rotman School of Management wanted to test the idea that social isolation might generate a physical feeling of coldness. In their first experiment, they divided a group of volunteers into two groups. One group recalled a personal experience in which they had been socially excluded-rejection from a club, for example. This was meant to tap into their feelings of isolation and loneliness. The other group recalled an experience in which they had been accepted into a group. Afterwards, volunteers were asked to estimate the temperature in the room. Those who recalled memories of being ostracized experienced the ambient temperature of the room as colder. In a second experiment, researchers triggered feelings of exclusion by having volunteers play a computer-simulated ball tossing game. The game was designed so that some of the volunteers had the ball tossed to them many times, but others were left out. Afterwards, all the volunteers rated the desirability of certain foods and beverages: hot coffee, crackers, an ice-cold Coke, an apple, and hot soup. The findings were striking. As reported in the September issue of Psychological Science, a journal of the Association for Psychological Science, the "unpopular" volunteers who had been ostracized during the computer game were much more likely than the others to want either hot soup or hot coffee. Their preference for warm food and drinks presumably resulted from physically feeling cold as a result of being excluded. "It's striking that people preferred hot coffee and soup more when socially excluded," Leonardelli said. "Our research suggests that warm chicken soup may be a literal coping mechanism for social isolation."

Individuals who are born deaf use the "hearing" part of their brain to feel touch and to see objects, suggests new research that highlights the plasticity of the human brain. The new study, detailed online July 11 in The Journal of Neuroscience, shows that deaf people use the so-called auditory cortex to process both touch and visual stimuli much more than hearing individuals do.

Re " A Dreaded School Test in France Becomes a Tool of Integration " (Fontenay-sous-Bois Journal, May 12): Several factors contribute to the necessity of retaining the dreaded dictation ( dict ée) as an essential tool in teaching the French language.

The idea that men and women use language differently is conventional wisdom-appearing everywhere from Cosmo and Glamour to The Journal of Psychology and Anthropological Linguistics. Recent research, though, suggests that the most important variable is not the sex of the person doing the talking, but that of the person being spoken to.

This Wall Street Journal interactive employs lyrics from the musical Hamilton as well as the song lyrics of the Fugees, Nas, Kendrick Lamar, Rakim, etc. to illustrate sound devices in context. Audio included.

"Our main conclusion is that delays in word onset facilitate word recognition, and that such facilitation is independent of the type of delay. ... Our findings support the perhaps counterintuitive conclusion that fillers like um can sometimes help (rather than hinder) listeners to identify spoken words. But critically, the data show that the same is true for silent pauses and pauses filled with artificially generated tones. "

Recently, people have been returning to writing basics: handwriting, notebooks, pens, paper, and stationary. While technology can certainly provide an edge for certain tasks, digital overload, addiction, and distraction are growing concerns. many studies indicate that multitasking is bad for us and makes our brains more scattered. In contrast, several studies suggest that pen and paper have an edge over the keyboard. In three studies, researchers found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. Those who took written notes had better comprehension and retention of material because they had to mentally process information rather than type it verbatim. And, another study, published in the Journal of Applied Cognitive Psychology, showed that people who doodle can better recall dull information. Writing it down also sparks innovation. Being innovative and creative is about "getting your hands dirty" a feeling that is lacking when you use technology or gadgets, says Arvind Malhotra, a professor at the University of North Carolina Kenan-Flagler Business School."Research has also shown that tactile sensory perceptions tend to stimulate parts of the brain that are associated with creativity. So, touch, feel and the sensation you get when you build something physical has also got a lot to do with creativity," he says.

This month, the journal Pediatrics published a study that used functional magnetic resonance imaging to study brain activity in 3-to 5-year-old children as they listened to age-appropriate stories. The researchers found differences in brain activation according to how much the children had been read to at home. Children whose parents reported more reading at home and more books in the home showed significantly greater activation of brain areas in a region of the left hemisphere called the parietal-temporal-occipital association cortex. This brain area is "a watershed region, all about multisensory integration, integrating sound and then visual stimulation," said the lead author, Dr. John S. Hutton, a clinical research fellow at Cincinnati Children's Hospital Medical Center. This region of the brain is known to be very active when older children read to themselves, but Dr. Hutton notes that it also lights up when younger children are hearing stories. What was especially novel was that children who were exposed to more books and home reading showed significantly more activity in the areas of the brain that process visual association, even though the child was in the scanner just listening to a story and could not see any pictures. "When kids are hearing stories, they're imagining in their mind's eye when they hear the story," said Dr. Hutton. "For example, 'The frog jumped over the log.' I've seen a frog before, I've seen a log before, what does that look like?" The different levels of brain activation, he said, suggest that children who have more practice in developing those visual images, as they look at picture books and listen to stories, may develop skills that will help them make images and stories out of words later on. "It helps them understand what things look like, and may help them transition to books without pictures," he said. "It will help them later be better readers because they've developed that part of the brain

Our brains are set up to do two things at once, but not three, a French team reports in the journal Science. Their experiment examined an area of the brain involved in goals and rewards and tested people's abilities to accomplish up to three mental tasks at the same time. When volunteers were doing just one task, there was activity in goal-oriented areas of both frontal lobes, suggesting that the two sides of the brain were working together to get the job done. But when people took on a second task, the lobes divided their responsibilities. Since the brain has only two frontal lobes, researchers surmised there might be a limit to the number of goals and rewards it can handle. Indeed, when people started a third task, one of the original goals disappeared from their brains. Also people slowed down and made many more mistakes.

Studies show that musicians are better at identifying emotion. "Looking for a mate who in everyday conversation can pick up even your most subtle emotional cues? Find a musician, Northwestern University researchers suggest. In a study in the latest issue of European Journal of Neuroscience, an interdisciplinary Northwestern research team for the first time provides biological evidence that musical training enhances an individual's ability to recognize emotion in sound."

Can babies learn to read? While parents use DVDs and other media in an attempt to teach their infants to read, these tools don't instill reading skills in babies, a study by researchers at New York University's Steinhardt School of Culture, Education, and Human Development has found. In their study, which appears in the Journal of Educational Psychology, the researchers examined 117 infants, aged nine to 18 months, who were randomly assigned to treatment and control groups. Children in the treatment condition received a baby media product, which included DVDs, word and picture flashcards, and flip books to be used daily over a seven-month period; children in the control condition did not receive these materials from the researchers. Over the course of seven months, the researchers conducted a home visit, four laboratory visits, and monthly assessments of language development. To test children's emerging skills in the laboratory, the researchers examined the capacity to recognize letter names, letter sounds, vocabulary, words identified on sight, and comprehension. A combination of eye-tracking tasks and standardized measures were used to study outcomes at each stage of development. Using a state-of-the art eye-tracking technology, which follows even the slightest eye movements, the researchers were able to closely monitor how the infants distributed their attention and how they shifted their gaze from one location to another when shown specific words and phrases. No discernible differences were observed between the results of the experimental group vs. the control; yet parents of the infants in the experimental group perceived that their children were, in fact, acquiring words. :-)

Information set to music, suggests research, is better retained, as it taps into time- honored strategies that help information stick. Tales that last for many generations tend to describe concrete actions rather than abstract concepts. They use powerful visual images. They are sung or chanted. And they employ patterns of sound: alliteration, assonance, repetition and, most of all, rhyme. A study by Rubin showed that when two words in a ballad are linked by rhyme, contemporary college students remember them better than non-rhyming words. Such universal characteristics of oral narratives are, in effect, mnemonics-memory aids that people developed over time "to make use of the strengths and avoid the weaknesses of human memory," as Rubin puts it. Songs and rhymes can be used to remember all kinds of information. A study just published in the journal Memory and Cognition finds that adults learned a new language more effectively when they sang it.

Wanda Wallace, in a study reported in the November 1994 _Journal of Experimental Psychology_, noted that the melody of a song, in some situations, can facilitate learning and recall. The experiments in this article demonstrate that text is better recalled when it is heard as a song rather than as speech, provided the music repeats so that it is easily learned. Furthermore, the experiments indicate that the melody contributes more than just rhythmic information. Music is a rich structure that chunks words and phrases, identifies line lengths, identifies stress patterns, and adds emphasis as well as focuses listeners on surface characteristics. The musical structure can assist in learning, in retrieving, and if necessary, in reconstructing a text.

UCLA researchers Oppenheimer and Mueller wondered if there was something about paper and the act of writing that explained this phenomenon, so they conducted an experiment. They asked about 50 students to attend a lecture. Half took notes on laptops and half with pen and paper. Both groups were then given a comprehension test. It wasn't even close. The students who used paper scored significantly higher than those who used laptops. Mueller attributes this unexpected finding - published in the journal, Psychological Science - to the fact that the "analog" note takers were forced to synthesize rather than merely transcribe. It's a phenomenon known as "desirable difficulty." "Desirable difficulty is some small roadblock that is in your path that actually improves your understanding of a topic," she explains.

Singing along to our favorite songs may actually be a skill we acquire even before we're born. According to a recent study published in the journal Ultrasound, unborn babies can "sing and dance" in the womb as early as 16 weeks.
