Sunday Science Highlights!

People Who Are Angry Pay More Attention to Rewards Than Threats

Anger is a negative emotion. But, like being happy or excited, feeling angry makes people want to seek rewards, according to a new study of emotion and visual attention. The researchers found that people who are angry pay more attention to rewards than to threats -- the opposite of people feeling other negative emotions like fear.

Previous research has shown that emotion affects what someone pays attention to. If a fearful or anxious person is given a choice of a rewarding picture, like a sexy couple, or a threatening picture, like a person waving a knife threateningly, they'll spend more time looking at the threat than at the rewarding picture. People feeling excitement, however, are the other way -- they'll go for the reward.

Adult Autism Diagnosis by Brain Scan

Scientists from the Institute of Psychiatry (IoP) at King's College London have developed a pioneering new method of diagnosing autism in adults. For the first time, a quick brain scan that takes just 15 minutes can identify adults with autism with over 90 per cent accuracy. The method could lead to the screening for autism spectrum disorders in children in the future.

Neurological Process for the Recognition of Letters and Numbers Explained

How does the brain link the visual basic traits of letters and numbers to abstract representations and to words? Scientists from the Basque Research Center on Cognition, Brain and Language have analyzed the influence of context on the visual recognition of a written word regardless of the format in which these letters may be display.

"We analyzed the influence of the context given by a word when linking the physical traits of its components to the abstract representations of letters," explains Nicola Molinaro, main author of the study and researcher of the Basque Research Center on Cognition, Brain and Language (BCBL).
