BY Ellen Rolfes Rebecca Kamen’s sculptures appear as delicate as the brain itself. Thin, green branches stretch from a colorful mass of vein-like filaments. The branches, made from pieces of translucent mylar and stained with diluted acrylic paint, are so delicate that they sway slightly when mounted to the wall. Perched on various parts of the sculpture are mylar butterflies, whose wings also move, as if fluttering. One of Kamen's influences is the writing of Santiago Ramon y Cajal, who is called the "father of modern neuroscience." Cajal once said: “Like the entomologist in search of colorful butterflies, my attention has chased in the gardens of the grey matter cells with delicate and elegant shapes, the mysterious butterflies of the soul, whose beating of wings may one day reveal to us the secrets of the mind." One of Kamen’s artistic influences is the writing of Santiago Ramon y Cajal, who is called the “father of modern neuroscience.” The work, called “Butterflies of the Soul” was inspired by neuroscientist Santiago Ramon y Cajal, who won the 1906 Nobel Prize, for his groundbreaking work on the human nervous system. Kamen’s sculpture is a nod to his work and the development of modern neuroscience. Cajal’s observation of the cells under the microscope radically changed how scientists study the brain and its functions, Kamen said. And the butterflies in her sculpture represent Cajal’s drawings of Purkinje cells, which are found in the cerebellar cortex at the base of the brain. Purkinje cells play an important role in motor control and in certain cognitive functions, such as attention and language. And attention and language are skills of great interest to Kamen, who has dyslexia. Her fascination with the brain and its structure deepened when she discovered that she was dyslexic later in life. © 1996 - 2014 MacNeil / Lehrer Productions.

By KATHERINE BOUTON Like almost all newborns in this country, Alex Justh was given a hearing test at birth. He failed, but his parents were told not to worry: He was a month premature and there was mucus in his ears. A month later, an otoacoustic emission test, which measures the response of hair cells in the inner ear, came back normal. Alex was the third son of Lydia Denworth and Mark Justh (pronounced Just), and at first they “reveled at what a sweet and peaceful baby he was,” Ms. Denworth writes in her new book, “I Can Hear You Whisper: An Intimate Journey Through the Science of Sound and Language,” being published this week by Dutton. But Alex began missing developmental milestones. He was slow to sit up, slow to stand, slow to walk. His mother felt a “vague uneasiness” at every delay. He seemed not to respond to questions, the kind one asks a baby: “Can you show me the cow?” she’d ask, reading “Goodnight, Moon.” Nothing. No response. At 18 months Alex unequivocally failed a hearing test, but there was still fluid in his ears, so the doctor recommended a second test. It wasn’t until 2005, when Alex was 2 ½, that they finally realized he had moderate to profound hearing loss in both ears. This is very late to detect deafness in a child; the ideal time is before the first birthday. Alex’s parents took him to Dr. Simon Parisier, an otolaryngologist at New York Eye and Ear Infirmary, who recommended a cochlear implant as soon as possible. “Age 3 marked a critical juncture in the development of language,” Ms. Denworth writes. “I began to truly understand that we were not just talking about Alex’s ears. We were talking about his brain.” © 2014 The New York Times Company

By Daisy Yuhas Greetings from Boston where the 21st annual meeting of the Cognitive Neuroscience Society is underway. Saturday and Sunday were packed with symposia, lectures and more than 400 posters. Here are just a few of the highlights. The bilingual brain has been a hot topic at the meeting this year, particularly as researchers grapple with the benefits and challenges of language learning. In news that will make many college language majors happy, a group of researchers led by Harriet Wood Bowden of the University of Tennessee-Knoxville have demonstrated that years of language study alter a person’s brain processing to be more like a native speaker’s brain. They found that native English speaking students with about seven semesters of study in Spanish show very similar brain activation to native speakers when processing spoken Spanish grammar. The study used electroencephalography, or EEG, in which electrodes are placed along the scalp to pick up and measure the electrical activity of neurons in the brain below. By contrast, students who have more recently begun studying Spanish show markedly different processing of these elements of the language. The study focused on the recognition of noun-adjective agreement, particularly in gender and number. Accents, however, can remain harder to master. Columbia University researchers worked with native Spanish speakers to study the difficulties encountered in hearing and reproducing English vowel sounds that are not used in Spanish. The research focused on the distinction between the extended o sound in “dock” and the soft u sound in “duck,” which is not part of spoken Spanish. The scientists used electroencephalograms to measure the brain responses to these vowel sounds in native-English and native-Spanish speakers. © 2014 Scientific American

By Deborah Serani Sometimes I work with children and adults who can’t put words to their feelings and thoughts. It’s not that they don’t want to – it’s more that they don’t know how. The clinical term for this experience is alexithymia and is defined as the inability to recognize emotions and their subtleties and textures [1]. Alexithymia throws a monkey wrench into a person’s ability to know their own self-experience or understand the intricacies of what others feel and think. Here are a few examples those with alexithymia experience: Difficulty identifying different types of feelings Limited understanding of what causes feelings Difficulty expressing feelings Difficulty recognizing facial cues in others Limited or rigid imagination Constricted style of thinking Hypersensitive to physical sensations Detached or tentative connection to others Alexithymia was first mentioned as a psychological construct in 1976 and was viewed as a deficit in emotional awareness [2]. Research suggests that approximately 8% of males and 2% of females experience alexithymia, and that it can come in mild, moderate and severe intensities [3]. Studies also show that alexithymia has two dimensions – a cognitive dimension, where a child or adult struggles to identify, interpret and verbalize feelings (the “thinking” part of our emotional experience). And an affective dimension, where difficulties arise in reacting, expressing, feeling and imagining (the “experiencing” part of our emotional experience) [4]. © 2014 Scientific American

by Bob Holmes People instinctively organise a new language according to a logical hierarchy, not simply by learning which words go together, as computer translation programs do. The finding may add further support to the notion that humans possess a "universal grammar", or innate capacity for language. The existence of a universal grammar has been in hot dispute among linguists ever since Noam Chomsky first proposed the idea half a century ago. If the theory is correct, this innate structure should leave some trace in the way people learn languages. To test the idea, Jennifer Culbertson, a linguist at George Mason University in Fairfax, Virginia, and her colleague David Adger of Queen Mary University of London, constructed an artificial "nanolanguage". They presented English-speaking volunteers with two-word phrases, such as "shoes blue" and "shoes two", which were supposed to belong to a new language somewhat like English. They then asked the volunteers to choose whether "shoes two blue" or "shoes blue two" would be the correct three-word phrase. In making this choice, the volunteers – who hadn't been exposed to any three-word phrases – would reveal their innate bias in language-learning. Would they rely on familiarity ("two" usually precedes "blue" in English), or would they follow a semantic hierarchy and put "blue" next to "shoe" (because it modifies the noun more tightly than "two", which merely counts how many)? © Copyright Reed Business Information Ltd.

by Hal Hodson Software has performed the first real-time translation of a dolphin whistle – and better data tools are giving fresh insights into primate communication too IT was late August 2013 and Denise Herzing was swimming in the Caribbean. The dolphin pod she had been tracking for the past 25 years was playing around her boat. Suddenly, she heard one of them say, "Sargassum". "I was like whoa! We have a match. I was stunned," says Herzing, who is the director of the Wild Dolphin Project. She was wearing a prototype dolphin translator called Cetacean Hearing and Telemetry (CHAT) and it had just translated a live dolphin whistle for the first time. It detected a whistle for sargassum, or seaweed, which she and her team had invented to use when playing with the dolphin pod. They hoped the dolphins would adopt the whistles, which are easy to distinguish from their own natural whistles – and they were not disappointed. When the computer picked up the sargassum whistle, Herzing heard her own recorded voice saying the word into her ear. As well as boosting our understanding of animal behaviour, the moment hints at the potential for using algorithms to analyse any activity where information is transmitted – including our daily activities (see "Scripts for life"). "It sounds like a fabulous observation, one you almost have to resist speculating on. It's provocative," says Michael Coen, a biostatistician at the University of Wisconsin-Madison. © Copyright Reed Business Information Ltd.

Imagine you’re calling a stranger—a possible employer, or someone you’ve admired from a distance—on the telephone for the first time. You want to make a good impression, and you’ve rehearsed your opening lines. What you probably don’t realize is that the person you’re calling is going to size you up the moment you utter “hello.” Psychologists have discovered that the simple, two-syllable sound carries enough information for listeners to draw conclusions about the speaker’s personality, such as how trustworthy he or she is. The discovery may help improve computer-generated and voice-activated technologies, experts say. “They’ve confirmed that people do make snap judgments when they hear someone’s voice,” says Drew Rendall, a psychologist at the University of Lethbridge in Canada. “And the judgments are made on very slim evidence.” Psychologists have shown that we can determine a great deal about someone’s personality by listening to them. But these researchers looked at what others hear in someone’s voice when listening to a lengthy speech, says Phil McAleer, a psychologist at the University of Glasgow in the United Kingdom and the lead author of the new study. No one had looked at how short a sentence we need to hear before making an assessment, although other studies had shown that we make quick judgments about people’s personalities from a first glance at their faces. “You can pick up clues about how dominant and trustworthy someone is within the first few minutes of meeting a stranger, based on visual cues,” McAleer says. To find out if there is similar information in a person’s voice, he and his colleagues decided to test “one of the quickest and shortest of sociable words, ‘Hello.’ ” © 2014 American Association for the Advancement of Science.

Matt Kaplan Humans are among the very few animals that constitute a threat to elephants. Yet not all people are a danger — and elephants seem to know it. The giants have shown a remarkable ability to use sight and scent to distinguish between African ethnic groups that have a history of attacking them and groups that do not. Now a study reveals that they can even discern these differences from words spoken in the local tongues. Biologists Karen McComb and Graeme Shannon at the University of Sussex in Brighton, UK, guessed that African elephants (Loxodonta africana) might be able to listen to human speech and make use of what they heard. To tease out whether this was true, they recorded the voices of men from two Kenyan ethnic groups calmly saying, “Look, look over there, a group of elephants is coming,” in their native languages. One of these groups was the semi-nomadic Maasai, some of whom periodically kill elephants during fierce competition for water or cattle-grazing space. The other was the Kamba, a crop-farming group that rarely has violent encounters with elephants. The researchers played the recordings to 47 elephant family groups at Amboseli National Park in Kenya and monitored the animals' behaviour. The differences were remarkable. When the elephants heard the Maasai, they were much more likely to cautiously smell the air or huddle together than when they heard the Kamba. Indeed, the animals bunched together nearly twice as tightly when they heard the Maasai. “We knew elephants could distinguish the Maasai and Kamba by their clothes and smells, but that they can also do so by their voices alone is really interesting,” says Fritz Vollrath, a zoologist at the University of Oxford, UK (see video below). © 2014 Nature Publishing Group

By ALBERT SUN On a frigid night recently in Randolph, N.J., the Jersey Wildcats junior hockey team flew across the home rink during practice at Aspen Ice Arena, sending ice into the air. Hockey is known for its collisions, and concussions aren’t unusual, but the players didn’t seem particularly worried. On the backs of their heads were flashing green lights, signifying that all was well. “We’ll be behind the bench, and as soon as a player comes back we can look right down and it’ll be a nice light,” said the coach, Justin Stanlick. If the light changes color, “we can know that player needs to go see a trainer to get cleared.” The light is part of a head impact sensor called the Checklight, made by Reebok. The device is a black skullcap with an electronic strip and three lights on the back. It blinks green when a player has sustained no head impact on the ice, yellow after a moderate impact and red after a severe one. The Checklight relies on an accelerometer and a gyroscope to measure the force of an impact. The Checklight flashes green for no impact, yellow for a moderate blow, red for a severe one.Bryan Thomas for The New York Times The Checklight flashes green for no impact, yellow for a moderate blow, red for a severe one. Coaches and parents have only to look to see if a player has taken a serious blow. And because the sensors are objective, Reebok executives say, they may lessen the pressure on young athletes to project toughness and play through a concussion. Gage Malinowski, a 19-year-old defenseman for the Wildcats, recently returned to practice after suffering the latest in a series of concussions during a game in February. “There’s not a game where I don’t have at least 10 hits,” he said. © 2014 The New York Times Company

by Graham Lawton In August 2013, professional rugby union player Andy Hazell received a massive blow to the head while playing for his club Gloucester. Six "horrendous" months later he retired from the game, stricken by dizziness, mood swings and a sense of detachment. Hazell isn't the first rugby player to experience concussion during a game, and probably won't be the last to have to retire as a result. According to a campaign launched this week, rugby union players don't know enough about the risks of concussion – and the governing bodies aren't doing enough to prevent it. The problem isn't so much one-off blows like the one that ended Hazell's career, but long-term damage caused by repeated concussions over many years. Studies of boxers and American footballers have shown that these can lead to a degenerative brain disease called Chronic Traumatic Encephalopathy (CTE). CTE leads to memory problems, personality change and slowness of movement. It usually shows up in middle age, long after a sporting career is over. CTE has been an issue in American Football for years. Thousands of ex-professionals sued the National Football League alleging that it knew about the risks but covered them up. Last year the NFL offered a $765 million settlement package. Neurologists have long suspected that other contact sports might also lead to CTE – particularly rugby union because of its emphasis on high-speed "hits". Concussion is the fourth most common injury in the professional game. © Copyright Reed Business Information Ltd.

By JOHN BRANCH Chronic traumatic encephalopathy, the degenerative brain disease linked to repeated blows to the head, has been found posthumously in a 29-year-old former soccer player, the strongest indication yet that the condition is not limited to athletes who played sports known for violent collisions, like football and boxing. Researchers at Boston University and the VA Boston Healthcare System, who have diagnosed scores of cases of C.T.E., said the player, Patrick Grange of Albuquerque, was the first named soccer player found to have C.T.E. On a four-point scale of severity, his disease was considered Stage 2. Soccer is a physical game but rarely a violent one. Players sometimes collide or fall to the ground, but the most repeated blows to the head may come from the act of heading an airborne ball — to redirect it purposely — in games and practices. Grange, who died in April after being found to have amyotrophic lateral sclerosis, was especially proud of his ability to head the ball, said his parents, Mike and Michele. They recalled him as a 3-year-old, endlessly tossing a soccer ball into the air and heading it into a net, a skill that he continued to practice and display in college and in top-level amateur and semiprofessional leagues in his quest to play Major League Soccer. Grange sustained a few memorable concussions, his parents said — falling hard as a toddler, being knocked unconscious in a high school game and once receiving 17 stitches in his head after an on-field collision in college. “He had very extensive frontal lobe damage,” said Dr. Ann McKee, the neuropathologist who performed the brain examination on Grange. “We have seen other athletes in their 20s with this level of pathology, but they’ve usually been football players.” © 2014 The New York Times Company

National Institutes of Health researchers have identified gene variants that cause a rare syndrome of sporadic fevers, skin rashes and recurring strokes, beginning early in childhood. The team’s discovery coincides with findings by an Israeli research group that identified an overlapping set of variants of the same gene in patients with a similar type of blood vessel inflammation. The NIH group first encountered a patient with the syndrome approximately 10 years ago. The patient, then 3 years old, experienced fevers, skin rash and strokes that left her severely disabled. Because there was no history of a similar illness in the family, the NIH group did not at first suspect a genetic cause, and treated the patient with immunosuppressive medication. However, when the NIH team evaluated a second patient with similar symptoms two years ago — a child who had experienced recurrent fevers and six strokes by her sixth birthday — they began to suspect a common genetic cause and embarked on a medical odyssey that has led not only to a diagnosis, but to fundamental new insights into blood vessel disease. In their study, which appears in the Feb. 19, 2014, advance online edition of the New England Journal of Medicine, the researchers describe how next-generation genome sequencing, only recently available, facilitated a molecular diagnosis for patients in their study. The researchers found that harmful variants in the CECR1 gene impede production of a protein vital to the integrity of healthy blood vessel walls. The researchers showed that faulty variants in their patients’ DNA that encode the CECR1 gene cause a loss of function of the gene’s ability to produce of an enzyme called adenosine deaminase 2 (ADA2). Without it, abnormalities and inflammation in blood vessel walls result. The researchers call the new syndrome, deficiency of ADA2, or DADA2.

Adrienne LaFrance For the better part of the past decade, Mark Kirby has been pouring drinks and booking gigs at the 55 Bar in New York City's Greenwich Village. The cozy dive bar is a neighborhood staple for live jazz that opened on the eve of Prohibition in 1919. It was the year Congress agreed to give American women the right to vote, and jazz was still in its infancy. Nearly a century later, the den-like bar is an anchor to the past in a city that's always changing. For Kirby, every night of work offers the chance to hear some of the liveliest jazz improvisation in Manhattan, an experience that's a bit like overhearing a great conversation. "There is overlapping, letting the other person say their piece, then you respond," Kirby told me. "Threads are picked up then dropped. There can be an overall mood and going off on tangents." Brain areas linked to meaning shut down during improvisational jazz interactions. In other words, this music is syntactic, not semantic. The idea that jazz can be a kind of conversation has long been an area of interest for Charles Limb, an otolaryngological surgeon at Johns Hopkins. So Limb, a musician himself, decided to map what was happening in the brains of musicians as they played. He and a team of researchers conducted a study that involved putting a musician in a functional MRI machine with a keyboard, and having him play a memorized piece of music and then a made-up piece of music as part of an improvisation with another musician in a control room. What researchers found: The brains of jazz musicians who are engaged with other musicians in spontaneous improvisation show robust activation in the same brain areas traditionally associated with spoken language and syntax. In other words, improvisational jazz conversations "take root in the brain as a language," Limb said. © 2014 by The Atlantic Monthly Group

CHICAGO, ILLINOIS—Chances are, your baby won’t respond to questions like, “How was your day, honey?” Or, “What do you want to be when you grow up?” But just because infants can’t form sentences until toddlerhood doesn’t mean that they don’t benefit from early conversations with their parents. It’s long been observed that the better children perform in school and the more successful their careers, the higher the socioeconomic status (SES) of their family—and, according to Stanford University’s Anne Fernald, this has a lot to do with how parents of different SES speak to their babies. Those babies that are spoken to frequently in an engaging and nurturing way—generally from a higher SES—tend to develop faster word-processing skills, or the ability to follow a sentence from one object or setting to another. This word processing speed, in turn, directly relates to the development not just of vocabulary and language skills, but also memory and nonverbal cognitive abilities. In a new study, Fernald and colleagues measured parent-baby banter from round-the-clock recordings in babies’ homes, then tested those babies’ word-processing speed using retinal-following experiments that tracked how long it took them to follow a prompt to an image like a dog or juice. The researchers found that the differences in word-processing speed between high and low SES were stark: By 2 years of age, high SES children were 6 months ahead of their low SES counterparts; and by age 3, the differences in processing abilities were highly predictive of later performance in and out of school, the team reported here today at the annual meeting of AAAS, which publishes Science. Fernald hopes that this research will lead to interventions that help to shrink the language gap between kids on either side of the income gap. © 2014 American Association for the Advancement of Science

|By Dina Fine Maron Concussions are a major problem in football. But brain injury is a growing concern in soccer, too, usually resulting from heading the ball or collisions. A meta-analysis of existing studies finds that concussions accounted for between 6 and 9 percent of all injuries sustained on soccer fields. Most of those concussions come from when two players make for the ball, often when a player’s elbow, arm or hand inadvertently makes contact with another player’s head. But we’re not just talking about injuries to professionals. One work shows some 63 percent of all varsity soccer players have sustained concussions—yet only 19 percent realized it. And another says girls’ soccer can be particularly brutal, accounting for 8 percent of all sports-related concussions among high school girls. The findings are in the journal Brain Injury. [Monica E. Maher et al., Concussions and heading in soccer: A review of the evidence of incidence, mechanisms, biomarkers and neurocognitive outcomes] Professional players who reported a great deal of extensive heading the ball during their careers did the poorest in tests of verbal and visual memory compared with other players. Goalies and defenders were most likely to get concussions. So if you want to bend it like Beckham, maybe focus on playing midfield or offense. Padding the goal posts would also be a heads-up policy. © 2014 Scientific American

Women have a poorer quality of life after a stroke than men, a study has found. The US research, published in Neurology, assessed the mental and physical health of 1,370 patients three months and a year after a stroke. Women had more depression and anxiety, pain and discomfort, and more restricted mobility. UK experts said women tended to have strokes later, and might therefore need more support. But the study did say more people survive a stroke now than 10 years ago because of improved treatment and prevention. The researchers at Wake Forest Baptist Medical Center, North Carolina, looked at patients who had had a stroke or transient ischaemic attack (TIA), also known as a mini-stroke. Quality of life is calculated using a formula that assesses mobility, self-care, everyday activities, depression/anxiety and pain. At three months, women were more likely than men to report problems with mobility, pain and discomfort, anxiety and depression, but the difference was greatest in those aged over 75. After a year, women still had lower quality-of-life scores overall than men but the difference between them was smaller. Support needs Prof Cheryl Bushnell, who led the study, said: "We found that women had a worse quality of life than men up to 12 months following a stroke." BBC © 2014

By JEFF Z. KLEIN Hockey players who sustained concussions during a recent season experienced acute microstructural changes in their brains, according to a series of studies published in the Journal of Neurosurgery on Tuesday. “We’ve seen evidence of chronic injuries later in life from head trauma, and now we’ve seen this in current players,” said Dr. Paul Echlin, an Ontario sports concussion specialist who conducted the study in collaboration with Dr. Martha Shenton of Brigham and Women’s Hospital and researchers from Harvard Medical School, Massachusetts General Hospital and Western University of Canada. The researchers said these were the first studies in which an independent medical team used magnetic resonance imaging analysis before, during and after a season to measure the effects of concussions on athletes. Forty-five male and female Canadian university hockey players were observed by independent physicians during the 2011-12 season. All 45 players were given M.R.I. scans before and after the season. The 11 who received a concussion diagnosis during the season were given additional scans within 72 hours, two weeks and two months of the incident. The scans found microscopic white matter and inflammatory changes in the brains of individuals who had sustained a clinically diagnosed concussion during the period of the study. Additional analysis found that players who sustained a concussion during the study period or reported a history of concussions showed significant differences in their brains’ white matter microstructure compared with players who did not sustain a concussion, or who reported no history of concussions. © 2014 The New York Times Company

by Aviva Rutkin "He moistened his lips uneasily." It sounds like a cheap romance novel, but this line is actually lifted from quite a different type of prose: a neuroscience study. Along with other sentences, including "Have you got enough blankets?" and "And what eyes they were", it was used to build the first map of how the brain processes the building blocks of speech – distinct units of sound known as phonemes. The map reveals that the brain devotes distinct areas to processing different types of phonemes. It might one day help efforts to read off what someone is hearing from a brain scan. "If you could see the brain of someone who is listening to speech, there is a rapid activation of different areas, each responding specifically to a particular feature the speaker is producing," says Nima Mesgarani, an electrical engineer at Columbia University in New York City. Snakes on a brain To build the map, Mesgarani's team turned to a group of volunteers who already had electrodes implanted in their brains as part of an unrelated treatment for epilepsy. The invasive electrodes sit directly on the surface of the brain, providing a unique and detailed view of neural activity. The researchers got the volunteers to listen to hundreds of snippets of speech taken from a database designed to provide an efficient way to cycle through a wide variety of phonemes, while monitoring the signals from the electrodes. As well as those already mentioned, sentences ran the gamut from "It had gone like clockwork" to "Junior, what on Earth's the matter with you?" to "Nobody likes snakes". © Copyright Reed Business Information Ltd.

By JULIET MACUR WILLOW PARK, Tex. — The Hall of Famer Rayfield Wright’s increasingly imperfect memory retains an indelible image of his first N.F.L. start. It was November 1969. The Dallas Cowboys against the Los Angeles Rams. Wright, a Cowboys offensive tackle, lined up opposite Deacon Jones, the Rams’ feared defensive end. “Hey, boy,” Jones growled. “Do your mama know you’re out here?” “What does my mama have anything to do with this?” Wright recalled thinking, losing his concentration just long enough for the ball to be snapped and for Jones to slap his dinner-plate-size right hand violently against Wright’s helmet. He hit him so hard that it sent Wright tumbling backward. Wright remembers being knocked out, then waking to see a galaxy of stars as he lay on the turf, unable to move. “It was as if I’d just been hit in the head by a baseball bat,” he said. He turned toward his sideline, looking to Coach Tom Landry for help. Landry just glanced at him, and then turned away. “Lord,” Wright thought. “I’m in this by myself.” For the longest time, he was sure that was true. It took Wright nearly 40 years to recognize that he probably sustained a concussion in his first N.F.L. start, one of many head injuries he says he had in 13 seasons with the Cowboys. Only recently — albeit through the fog of his worsening dementia, which he acknowledged publicly for the first time last week in an interview at his Texas home — has he realized that he is not in this by himself after all. © 2014 The New York Times Company

by Laura Sanders Growing up, I loved it when my parents read aloud the stories of the Berenstain Bears living in their treehouse. So while I was pregnant with my daughter, I imagined lots of cuddly quiet time with her in a comfy chair, reading about the latest adventures of Brother and Sister. Of course, reality soon let me know just how ridiculous that idea was. My newborn couldn’t see more than a foot away, cried robustly and frequently for mysterious reasons, and didn’t really understand words yet. Baby V was simply not interested in the latest dispatch from Bear County. When I started reading child development expert Elaine Reese’s new book Tell Me a Story, I realized that I was not the only one with idyllic story time dreams. Babies and toddlers are squirmy, active people with short attention spans. “Why, then, do we cling to this soft-focus view of storytelling when we know it is unrealistic?” she writes. These days, as Baby V closes in on the 1-year mark, she has turned into a most definite book lover. But it’s not the stories that enchant her. It’s holding the book, turning its pages back to front to back again, flipping it over and generally showing it who’s in charge. Every so often I can entice Baby V to sit on my lap with a book, but we never read through a full story. Instead, we linger on the page with all the junk food that the Hungry Caterpillar chomps through, sticking our fingers in the little holes in the pages. And we make Froggy pop in and out of the bucket. And we study the little goats as they climb up and up and up on the hay bales. © Society for Science & the Public 2000 - 2014
