 E-Mail A unique residential study has concluded that, contrary to perceived wisdom, people with eating disorders do not lose self-control - leading to binge-eating - in response to stress. The findings of the Cambridge-led research are published today in the Journal of Neuroscience. People who experience bulimia nervosa and a subset of those affected by anorexia nervosa share certain key symptoms, namely recurrent binge-eating and compensatory behaviours, such as vomiting. The two disorders are largely differentiated by body mass index (BMI): adults affected by anorexia nervosa tend to hav...

 E-Mail A shared set of systems in the brain may play an important role in controlling the retrieval of facts and personal memories utilised in everyday life, new research shows. Scientists from the University of York say their findings may have relevance to memory disorders, including dementia, where problems remembering relevant information can impact on the daily life of patients. Researchers say the findings may also have important implications for the development of a new generation of artificial intelligence systems, which use long-term memory in solving computational problems. The bra...

 E-Mail PULLMAN, Wash. - The ability to control your own behavior, known as executive function, might not exist all in your head. A new theory proposes that it develops with many influences from outside the mind. The theory, detailed in Perspectives on Psychological Science, draws on dynamic systems theory which originated in mathematics and physics and has been used to describe complex organizing phenomena like cloud formation and flying patterns of birds. Now, a research team led by Washington State University human development assistant professor Sammy Perone is applying it to executive...

April 1, 2021. A team of New Jersey researchers has shown that changes in perceptual certainty and response bias, two central metrics of signal detection theory (SDT), correlate with changes in cognitive fatigue. They also show that SDT measures change as a function of changes in brain ac...
