We study the wisdom of crowd in three sequential decision-making tasks: Balloon Analogue Risk Task (BART), optimal stopping problems, and bandit problems. consider a behavior-based approach, using majority decisions to determine behavior show that this approach performs poorly BART tasks. The key problem is becomes progressively more extreme as decision sequence progresses, because diversity op...

During daily encounters, it is inevitable that people take risks. Investigating the sequential processing of risk hazards involve expectation formation about outcome contingencies. The present study aimed to explore risk behavior and its neural correlates in sequences of decision making, particularly in old age, which represents a critical period regarding risk-taking propensity. The Balloon An...

Structural and functional brain development is thought to lead to different developmental progressions of cognitive control, risk/reward processing, and social cognition during adolescence. We compared these abilities in a cross-sectional sample of 90 adolescents aged 12, 15, or 17 years old, using computerized measures of inhibitory control (Go/No-Go task), risk-taking (Balloon Analogue Risk t...

Economists define risk in terms of the variability of possible outcomes, whereas clinicians and laypeople generally view risk as exposure to possible loss or harm. Neuroeconomic studies using relatively simple behavioral tasks have identified a network of brain regions that respond to economic risk, but these studies have had limited success predicting naturalistic risk-taking. By contrast, mor...

Abstract Arguably, extreme sports athletes exhibit a more significant risk appetite than the general public. Are standard behavioral measures able to capture this? To answer this question, we assessed self-reports of taking and measured risk-taking behavior samples snowboarders climbers. Two groups non-athletes, university students crowdworkers, sport that does not include potential grave injur...
