Researchers have developed a new method to analyse facial expressions, as part of efforts to better understand animal communication.
People with alcohol use disorder (AUD) are less able to learn from others’ negative experiences, potentially rendering them more vulnerable to maintaining their dangerous drinking or relapsing, according to the first study of its type. The study explored social cognition, processes that enable us to understand and interact with others, and specifically social learning, our ability to learn by observing others’ experiences.
People who need to drink relatively high amounts of alcohol before feeling its effects, a genetically influenced risk factor for future heavy drinking and alcohol problems, may have differences in brain connectivity that impair their ability to interpret facial expressions and recognize their own intoxication, a new study suggests. The paper, in Alcoholism: Clinical & Experimental Research, is believed to be the first to demonstrate differences in brain connectivity between people with low and high responses to alcohol. Varying levels of responses to alcohol — for example, how many drinks a person consumes before feeling intoxicated — are known to be related to neurobiological processing. Low responders, who drink more alcohol before feeling affected by it, are at greater risk of alcohol use disorder (AUD) than high responders, who feel the effects of fewer drinks. Scientists using functional magnetic resonance imaging (fMRI) are exploring the possibility that low responders are less a
