Spontaneous Brain Fluctuations Influence Risk-taking

Minute-to-minute fluctuations in human brain activity, associated with changing levels of dopamine, impact whether we make risky decisions, a new University College London study has found. The findings could help explain why humans are inconsistent and sometimes irrational. “Experts have long struggled to explain why people are so erratic, making one decision one day and […]

Anxious People Exert More Cognitive Control During Risky Decisions

That anxious people take fewer risks is hardly surprising. But a team of psychologists from the German Friedrich Schiller University Jena, together with partners from Würzburg in Germany and the Canadian University of Victoria have succeeded in making this decision process visible in the brain, allowing them to predict the behaviour of individuals. The researchers conducted […]

Helmet Wearing Increases Risk Taking And Sensation Seeking

Wearing a helmet in an effort to stay safe is likely to increase sensation seeking and could conversely make us less safe and more inclined to take risks, according to a new study. The latest findings call into question the effectiveness of certain safety advice, notably in relation to helmets for various leisure activities, including […]

A Single Brain Connection Predicts Risky Gambling

Scientists tracked the activity in two brain regions and found that people who have a strong connection between the two regions are less likely to place a risky bet. Says Brian Knutson, associate professor of psychology at Stanford University: “Activity in one brain region appears to indicate ‘uh oh, I might lose money,’ but in […]

Psychiatric Assessments For Predicting Violence Ineffective

Researchers have proposed an entirely new approach to risk assessment for future violence. Previous approaches have relied on looking at risk factors that happen to be linked to, but may not cause, violence, for example, being young, male, of lower social class, with previous violent convictions. The new approach is instead based on identifying risk […]
