A new study published in the Journal of Psychopharmacology, conducted by researchers from the University of Liverpool, Maastricht University and King's College London, shows that bilingual speakers' ability to speak a second language is improved after they have consumed a low dose of alcohol.
The concept of 'collective intelligence' is simple -- it asserts that if a team performs well on one task, it will repeat that success on other projects, regardless of the scope or focus of the work. While it sounds good in theory, it doesn't work that way in reality, according to an Iowa State University researcher.
One of the two brain-training methods most scientists use in research is significantly better in improving memory and attention. It also results in more significant changes in brain activity.
HRL Laboratories, LLC, researchers have determined how non-invasive transcranial direct current stimulation (tDCS) could increase associative learning. When applied to the prefrontal cortex, tDCS affected the brain widely, changing functional connectivity between areas, and accelerating learning in macaques. This confirmation potentially resolves controversy over reports claiming no effect on neuron firing rates in cadaver heads, believed to be the mechanism of interest. The HRL study confirmed faster learning regardless of neuron firing rates.
There has been little research on end-of-life decision-making for the growing population of older Americans with intellectual disabilities. Through a series of interviews with five different emergency medical service agencies in upstate New York, UB researchers asked EMS providers specifically how pre-hospital orders shape what they do in the case of someone with an intellectual disability.
People who are presented with political statements contradictory to their own beliefs tend to think harder and produce better arguments, according to research from Binghamton University, State University of New York.
A study from MIT reveals babies as young as 15 months can learn the value of hard work. Researchers found babies who watched an adult struggle to reach two different goals before succeeding tried harder at their own difficult task than babies who saw an adult succeed effortlessly.
As political rhetoric containing promises of education, social opportunities and other development for disadvantaged people continues to fill the airwaves, economics researchers have developed state-of-the-art statistical methods that uncover the impact of different aspects of upward mobility (or lack thereof), aside from parental income. The new research, titled 'Status Traps,' appears in a recent issue of the Journal of Business & Economic Statistics.
Male sex is a risk factor for worse outcome following neonatal insult, including hypoxic ischemia. While N-acetylcysteine and hypothermia promote functional improvement in female rodents, similar improvement in males requires the addition of vitamin D, report investigators at the Medical University of South Carolina in the September 1, 2017 issue of Neuropharmacology. Multi-mechanism approaches are needed to treat neonatal hypoxic ischemia, and those approaches appear to be different depending on sex.
Feeling tired? Even if we aren't tired, why do we yawn if someone else does? Experts at the University of Nottingham have published research that suggests the human propensity for contagious yawning is triggered automatically by primitive reflexes in the primary motor cortex -- an area of the brain responsible for motor function. Their study is another stage in their research into the underlying biology of neuropsychiatric disorders and their search for new methods of treatment.
