Acceleration models are at the core of operational driving behaviors, and include carfollowing models which capture interactions between a lead and following vehicles. The main assumption in these models is that the behavior of the following vehicle (e.g. change in acceleration) is directly related to a stimulus observed/perceived by the driver, defined relative to the lead vehicle (e.g. differ...

This paper explores people’s behavior when they are facing financial risks. Through the setting of an economics experiment, people’s willingness to bear financial risks and their tendency to impose risks on others are investigated. The experiment result shows that most people are risk-neutral or risk-averse when making decision under financial environment, and their tendency to impose risks on ...

Our study analyzes the determinants of investors’ risk taking behavior. We find that investors’ risk taking behavior such as portfolio choices can be predicted using risk attitudes, risk perceptions and belief measures such as optimism and overconfidence. However, the predictive power of these determinants heavily depends on the domain in which they were elicited. More specifically, risk attitu...

Risk-taking behavior is characterized by pursuit of reward in spite of potential negative consequences. Dopamine neurotransmission along the mesocorticolimbic pathway is a potential modulator of risk behavior. In patients with Parkinson's disease (PD), impulse control disorder (ICD) can result from dopaminergic medication use, particularly dopamine agonists (DAA). Behaviors associated with ICD ...

Attachment theory focuses on the bond that develops between child and caretaker and the consequences that this bond has on the child’s future relationships. Adolescents attempt to define their identity by experiencing various risky behaviors. The first aim of the study was whether risk taking behavior differs according to attachment styles. The second was to examine risk taking behavior differe...

INTRODUCTION Research demonstrates that cognitive biases toward drug-related stimuli are correlated with substance use. This study aimed to investigate differences in cognitive biases (i.e., approach bias, attentional bias, and memory associations) between smoking and non-smoking adolescents in the US and the Netherlands. Within the group of smokers, we examined the relative predictive value of...

Loss aversion, a well-documented behavioral phenomenon, characterizes decisions under risk in adult populations. As such, loss aversion may provide a reliable measure of risky behavior. Surprisingly, little is known about loss aversion in adolescents, a group who manifests risk-taking behavior, or in anxiety disorders, which are associated with risk-avoidance. Finally, loss aversion is expected...
