Young boys continue to have the highest rate of autism diagnoses, but Danish doctors are diagnosing more girls, teenagers and adults with the disorder than they did in the mid-1990s.
While previous studies have suggested a connection between contagious yawning and empathy, new research from the Duke Center for Human Genome Variation finds that contagious yawning may decrease with age and is not strongly related to variables like empathy, tiredness and energy levels.
CHORI Scientists Rhonda Patrick, PhD and Bruce Ames, PhD, find causal link between Vitamin D, serotonin and autism. The findings point towards possible prevention and treatment options.
Frequent Facebook users might be sharing more than party pictures, vacation videos and shameless selfies — they also share a greater risk of eating disorders, according to a new study led by Florida State University researchers.
A new University of Virginia psychology study has found that a sample of mostly white American children – as young as 7, and particularly by age 10 – report that black children feel less pain than white children.
Vanderbilt biologists have discovered that mosquito sperm have a “sense of smell” and that some of same chemicals that the mosquito can smell cause the sperm to swim harder.
Young adults who care for an animal may have stronger social relationships and connection to their communities, according to a paper published online today in Applied Developmental Science.
New research finds that while a majority of adults cite the ability to compete with friends as their primary reason for playing online casual video games such as Bejeweled Blitz, they report differing perceived benefits from playing the games based upon their age.
On January 29, JoVE, the Journal of Visualized Experiments, will publish a procedure to identify newborns and children at-risk for developmental problems, especially those born prematurely. The technique is an infant friendly way of measuring brain activity using non-traditional methods, and it will aid in the invention of treatment strategies leveraging neural plasticity present in the first three years of life.
The development of physical aggression in toddlers is strongly associated genetic factors and to a lesser degree with the environment, according to a new study led by Eric Lacourse of the University of Montreal and its affiliated CHU Sainte-Justine Hospital. Lacourse’s worked with the parents of identical and non-identical twins to evaluate and compare their behaviour, environment and genetics.
More independent work environments may lead to reductions in autism symptoms and improve daily living in adults with the disorder, according to a new study released in the Journal of Autism and Developmental Disorders.
Empathy-driven behavior has been observed in rats who will free trapped companions from restrainers. This behavior also extends toward strangers, but requires prior, positive social interactions with the type (strain) of the unfamiliar individual, report scientists from the University of Chicago in the open access journal eLife, on Jan. 14. The findings suggest that social experiences, not genetics or kin selection, determine whether an individual will help strangers out of empathy. The importance of social experience extends even to rats of the same strain—a rat fostered and raised with a strain different than itself will not help strangers of its own kind.
Caffeine is the energy boost of choice for millions. Now, however, researchers have found another use for the stimulant: memory enhancer.
Even before babies have language skills or much information about social structures, they can infer whether other people are likely to be friends by observing their likes and dislikes, a new study on infant cognition has found.
Love may be a battlefield, but most wouldn't expect the fighters to be a parasitic virus and its cricket host. Just like a common cold changes our behavior, sick crickets typically lose interest in everyday activities. But when Dr. Shelley Adamo of Dalhousie University found her cricket colony decimated by a pathogen, she was shocked that the dying insects didn't act sick. Not only had the infected crickets lost their usual starvation response, but they also continued to mate. A lot. How were the pathogen and the exuberant amorous behavior in the sick crickets connected?
New research by Vanderbilt marketing professor Kelly Haws found that consumers may be just as willing to buy healthy food if they feel they’re still getting a "supersize" deal.
Parents and other adults heap the highest praise on children who are most likely to be hurt by the compliments, a new study finds.
Prescribing both a stimulant and an antipsychotic drug to children with physical aggression and attention-deficit/hyperactivity disorder (ADHD), along with teaching parents to use behavior management techniques, reduces aggressive and serious behavioral problems in the children, according to esearchers at The Ohio State University Wexner Medical Center.
UT Southwestern neuroscience researchers have identified a gene that controls the response to cocaine by comparing closely related strains of mice often used to study addiction and behavior patterns.
Small talk is far from "small" or trivial, says psychology professor and shyness expert Bernardo J. Carducci. It is the salve of a disconnected society -- the "cornerstone of civility." "Small talk is really, really important. It helps us connect with people, and not just at holiday gatherings," said Carducci, director of the Shyness Research Institute at Indiana University Southeast. "If you make connections with people, it makes it much more difficult for you to treat them in an uncivil way. If you think about being kind to and connecting with people, people you engage in conversation, you're going to open a door for them, you'll let them step in front of you in line. You'll engage in more acts of kindness and fewer acts of rudeness."
Young adults who are heavy users of the Internet may also exhibit signs of addiction, say researchers at Missouri University of Science and Technology, Duke University Medical Center and the Duke Institute of Brain Sciences in a new study that compares Internet usage with measures of addiction.
Celebrities have substantial sway as health advisers, as there are strong biological, psychological and social bases for why people follow celebrity medical advice, say McMaster University researchers. Celebrity power can be harnessed to disseminate information based on best available research or abused to promote useless treatments. The researchers add that health professionals can counter the negative influences.
A cross-cultural study, led by Iowa State University researchers, shows prosocial media positively influence behavior regardless of culture. The study, a first-of-its-kind, tested empathy and helpfulness of thousands of children in seven countries.
A new study suggests that political bias can influence how people perceive the facial characteristics of a presidential candidate – even after seeing his face on TV thousands of times.
APA report on gun violence.
To protect themselves, some animals rapidly change color when their environments change, but chameleons change colors in unusual ways when they interact with other chameleons. Arizona State University researchers have discovered that these color changes don’t happen “out-of-the-blue” — instead, they convey different types of information during important social interactions.
A UAB study shows early maturing in adolescent girls can increase aggressive and delinquent behavior.
Saint Louis University nursing instructor Julie Bertram found mental health nurses lend valuable perspective in treating troubled teens in foster care.
Medical researchers point to developmental factors, specifically the decline of the sleep-inducing hormone melatonin, as an explanation for why children get less sleep as they become teenagers. But a new study suggests that social ties, including relationships with peers and parents, may be even more responsible for changing sleep patterns among adolescents.
University of Adelaide researchers have discovered the first evidence that the nerves in the stomach act as a circadian clock, limiting food intake to specific times of the day.
A psychological study has found that skilled typists can’t identify the positions of many of the keys on the QWERTY keyboard and probably didn’t memorize them even when they first learned to type.
Some song sparrows are more effusive than others in defending territory. New University of Washington findings show consistent individual differences not only for how aggressive individual song sparrows are but also for how much they use signals to communicate aggressive intentions.
Fear of being single is a meaningful predictor of settling for less in relationships among both men and women, a new University of Toronto study has found. The results are published in the December edition of the Journal of Personality and Social Psychology.
Prenatal exposure to alcohol severely disrupts major features of brain development that potentially lead to increased anxiety and poor motor function, conditions typical in humans with Fetal Alcohol Spectrum Disorders, say neuroscientists at UC Riverside.
A New Zealand bird that conspicuously displays its status on the top of its head can provide valuable insight into the social conventions of all creatures, including humans, scientists have found.
Parents, let your children get messy in the high chair: They learn better that way. That's according to a new study from the University of Iowa, which concludes that a 16-month-old's setting and degree of interaction enhances his or her ability to identify nonsolid objects and name them. Results published in the journal Developmental Science.
Do drinking and marriage mix? That depends on who’s doing the drinking — and how much — according to a recent study by the University at Buffalo Research Institute on Addictions (RIA).
New study shows peer groups formed in shared high school classes significantly affect students' academic performance.
Even as the rate of diagnosis has reached 11 percent among American children aged 4 to 17, neuroscientists are still trying to understand attention deficit hyperactivity disorder (ADHD). One classic symptom is impulsivity — the tendency to act before thinking.
The amount of gun violence shown in PG-13 films has more than tripled since 1985, the year the rating was introduced.
First randomized trial shows that texts and calls from parent coaches to young, at-risk mothers improved their parenting skills as well as their well-being and that of their children.
For the first time, Arizona State University researchers have discovered that at least in ants, animals can change their decision-making strategies based on experience. They can also use that experience to weigh different options.
There’s good news and there’s bad news. Which do you want to hear first? That depends on whether you are the giver or receiver of bad news, and if the news-giver wants the receiver to act on the information, according to researchers at the University of California, Riverside.
It is the first study to show that mindfulness training can be used in combination with cognitive behavioral therapy to protect attentional functioning in high-risk incarcerated youth.
Viewing R-rated movies leads to decreased church attendance and lessens importance of faith among young people, according to a study by a Baylor University researcher published online in the Review of Religious Research.
Iowa State University researchers looked at how prices, parents and peers affect fruit and vegetable consumption among African-American youths. Researchers say understanding these factors can help design more effective policy interventions.
The report looks at media consumption by individuals in and out of the home, excluding the workplace, between 2008 and 2015, breaking “media” down into 30 categories of media type and delivery (e.g. television, social media, computer gaming
More than 1 in 10 Americans take antidepressants, but these medications can take weeks—and for some patients, months—before they begin to alleviate symptoms. Now, scientists from the University of Chicago have discovered that selectively blocking a serotonin receptor subtype induces fast-acting antidepressant effects in mice, indicating a potential new class of therapeutics for depression. The work was published Oct. 29 in Molecular Psychiatry.
Psychology researchers find people with similar personality types are so likely to cluster in certain areas of the United States.
People who have had what they believe to be supernatural experiences are more likely to be “religious givers,” with their behavior based on cost-benefit principles that work in other transactions — whether that be through Amazon.com or an auto repair shop, according to a Baylor University study.
