Adult male mice lacking a gene linked to intellectual disability have trouble completing and remembering mazes, with no changes in social or repetitive behavior, according to new research published in JNeurosci. This animal model provides a new way to study the role of this gene in learning and memory and provides a rodent model of pure intellectual disability.
Subjected to the same practice exercise, the group of students that participated in mindfulness sessions obtained better results than those that did not take part in this activity.
As is true in humans, chimpanzees' general intelligence is correlated to their ability to exert self-control and delay gratification, according to new research at Georgia State University.
Spending too much time in dimly lit rooms and offices may actually change the brain's structure and hurt one's ability to remember and learn, indicates groundbreaking research by Michigan State University neuroscientists.
Researchers at Rutgers New Jersey Medical School have developed a two-minute questionnaire for parents that could help pediatricians and other primary care providers detect autism in toddlers, at a time when intervention might be crucial. The Psychological Development Questionnaire (PDQ-1) had an 88 percent likelihood of correctly identifying which of the youngster that screened positive because of the questionnaire had autism spectrum disorder (ASD).
Researchers at the US Army Research Laboratory and the University of Texas at Austin have developed new techniques for robots or computer programs to learn how to perform tasks by interacting with a human instructor. The findings of the study will be presented and published at the Association for the Advancement of Artificial Intelligence Conference in New Orleans, Louisiana, Feb. 2-7.
New research shows adults who develop psychotic disorders experience declines in IQ during childhood and adolescence, falling progressively further behind their peers across a range of cognitive abilities. The researchers from King's College London's Institute of Psychiatry, Psychology & Neuroscience (IoPPN) and Icahn School of Medicine at Mount Sinai in the United States found falls in IQ start in early childhood, and suggest educational interventions could potentially delay the onset of mental illness.
The brain's ability to categorize based on straightforward resemblance or on a more abstract similarity arises from its use of distinct rhythms, at distinct times, in distinct parts of the prefrontal cortex. Gamma in one region handles sensory comparisons, but beta in another region considers the less obvious ways things go together.
Children born with very low birth weights are at an increased risk of cognitive, emotional and behavioral problems throughout their lives. But what exactly happens in the brain to cause these problems?
BYU researchers developed an algorithm that teaches machines not just to win games, but to cooperate and compromise -- and sometimes do a little trash-talking too.
