Strangers reach mutual understanding through talking and asking questions, not from non-verbal cues

Strangers reach mutual understanding through talking and asking questions, not from non-verbal cues

Psychologists at The University of Texas at Arlington have discovered that when two strangers meet and interact for the first time, the extent to which they develop mutual understanding depends on how much they talk and ask questions rather than on non-verbal cues such as gestures or exchanging glances.

The UTA researchers used a specialized linguistic program to measure the extent that two strangers "get in synch" linguistically, providing new insight into the processes that underlie how people come to understand each other when they meet for the first time.

Bad behavior may not be a result of bad parenting, but a lack of common language

Bad behavior may not be a result of bad parenting, but a lack of common language

AMES, Iowa - Most parents will admit that talking with a teenage child is difficult at times. It is even more challenging when parents and children don't speak the same language fluently -- a reality for a growing number of immigrant families in the United States.

Study shows long-term marijuana use changes brain's reward circuit

Study shows long-term marijuana use changes brain's reward circuit

Chronic marijuana use disrupts the brain's natural reward processes, according to researchers at the Center for BrainHealth at The University of Texas at Dallas.

In a paper published in Human Brain Mapping, researchers demonstrated for the first time with functional magnetic resonance imaging that long-term marijuana users had more brain activity in the mesocorticolimbic-reward system when presented with cannabis cues than with natural reward cues.

Chivalry is not dead when it comes to morality

We're more likely to sacrifice a man than a woman when it comes to both saving the lives of others and in pursuing our self-interests, a team of psychology researchers has found.

"Our study indicates that we think women's welfare should be preserved over men's," observes Oriel FeldmanHall, a post-doctoral researcher at New York University and the study's lead author.

Replicating psychiatrists' expertise to prevent inpatient suicide

Climbing suicide rates over the past ten years have prompted three Joint Commission Sentinel Event Alerts -- the most recent in February 2016 - urging health care organizations to step up screening and detection of those individuals most at risk. But due to a shortage of both time and psychiatry staff, complying with this mandate presents a challenge. A tablet-based suicide risk assessment tool developed by researchers at the University of Vermont may provide clinicians in the hospital with a solution.

Rowan researchers develop blood test that detects early Alzheimer's disease

STRATFORD, NJ - A research team, led by Dr. Robert Nagele from Rowan University School of Osteopathic Medicine and Durin Technologies, Inc., has announced the development of a blood test that leverages the body's immune response system to detect an early stage of Alzheimer's disease - referred to as the mild cognitive impairment (MCI) stage - with unparalleled accuracy.

Trauma in childhood linked to drug use in adolescence

June 8, 2016 -- Latest research from a national sample of almost 10,000 U.S. adolescents found psychological trauma, especially abuse and domestic violence before age 11, can increase the likelihood of experimentation with drugs in adolescence, independent of a history of mental illness. Results of the study conducted at Columbia University's Mailman School of Public Health are published online in the Journal of the American Academy of Child and Adolescent Psychiatry.

This is the first study to document these associations in a national sample of adolescents.

Children who spend extra week in the womb have higher school test scores, risk disability

Researchers have found that spending a week longer in the womb may give babies a tiny leg up on cognitive ability. The trade-off, however, seems to be a slight increase in the chance of having a physical disability.

Preschool academic skills improve only when instruction is good to excellent

New research combining eight large child care studies reveals that preschools prepare children to succeed academically when teachers provide higher quality instruction.

Study finds differences in male, female brain activity when it comes to cooperation

Studies have long shown that when faced with a problem that must be solved by cooperating with others, males and females approach the task differently. Now, researchers at the Stanford University School of Medicine have discovered how those differences are reflected in brain activity.

When the researchers asked people to cooperate with a partner and then tracked the brain activity of both participants, they found that males and females had different patterns of brain activity.
