Patients with psychosis have accelerated aging of two brain networks important for general cognition -- the frontoparietal network (FPN) and cingulo-opercular network (CON) -- according to a new study in Biological Psychiatry.
The cleaner wrasse fish (Labroides dimidiatus), responds to its reflection and attempts to remove marks on its body during the mirror test -- a method considered the gold standard for determining self-awareness in animals. The finding, publishing on Feb. 7 in the open-access journal PLOS Biology, suggests that fish might possess far higher cognitive powers than previously thought, and ignites a high-stakes debate over how we assess the intelligence of animals that are so unlike ourselves.
Previous studies have suggested that having a higher level of education may protect the brain to some extent against dementia, providing a 'cognitive reserve' that buffers against the disease. But results have been mixed, and a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the Feb. 6, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.
Larger dogs have better short-term memory and self-control than smaller breeds, according to research led by the Arizona Canine Cognition Center at the University of Arizona.
There is only scant scientific evidence on whether the genetic risk for developing specific psychiatric disorders or cognitive traits is manifest in brain structure from childhood and, to date, studies have focused primarily on adult populations. The question remains unanswered. New evidence has now been provided by a study led by a researcher from the Barcelona Institute for Global Health (ISGlobal), a centre supported by 'la Caixa', which analysed data from a large paediatric sample.
Seaver Autism Center study results contribute to understanding of patterns of cognitive functioning in adults with autism and highlight the importance of a broader approach when studying cognition.
People who hold radical political views -- at either end of the political spectrum -- aren't as good as moderates at knowing when they're wrong, even about something unrelated to politics, finds a new UCL study.
the study shows that the beneficial effects of training in the brain and intelligence are greater when an educator implement a coaching strategy design in order to help the child to understand their training process
Using a large dataset and controlling for a variety of factors, including sex, age, height, socioeconomic status, and genetic ancestry, Gideon Nave of the Wharton School and Philipp Koellinger of Vrije Universiteit Amsterdam found that people with larger brains rated higher on measures of intelligence and educational attainment. Size was far from everything, however, explaining only about two percent of the variation in smarts.
Adults who had received early life, intensive childhood educational intervention display high levels of fairness in social interactions more than 40 years later, even when being fair comes at a high personal cost, according to a new study by Virginia Tech Carilion Research Institute scientists.
