We examine how different types of risk presentation numerical descriptions, experience sampling, graphical displays, and a combination of these formats in a ‘risk tool simulation’influence asset allocations in an experimental investment portfolio. Participants viewed information about a risky and a risk free fund and made a portfolio allocation. Risky allocations were elevated in the risk tool ...

BACKGROUND Risky decision-making is commonly observed in persons at risk for and infected with HIV and is associated with executive dysfunction. Yet it is currently unknown whether HIV alters brain processing of risk-taking decision-making. METHODS This study examined the neural substrate of a risky decision-making task in 21 HIV seropositive (HIV+) and 19 seronegative (HIV-) comparison parti...

Current combination antiretroviral therapies (ARV) are widely used to treat HIV. However drug-resistant strains of HIV have quickly evolved, and the level of risky behaviour has increased in certain communities. Hence, currently the overall impact that ARV will have on HIV epidemics remains unclear. We have used a mathematical model to predict whether the current therapies: are reducing the sev...

introduction: motorcycling is a risky activity and motorcyclists are vulnerable to road accidents. the behavior of motorcyclists is a significant factor of accident. unfortunately there is little information regarding social and mental characteristics of motorcyclists which lead to the accident. the purpose of this study was to gain an in-depth qualitative understanding of reasons for riding a ...

The present study examines the individual and joint contributions of personality, situations, and relationship contexts as they shape risky sexual behaviors. Data on 7,511 discrete sexual events collected from a community sample of 1,946 young adults were analyzed with multilevel modeling. Results showed that meaningful between-persons differences in risky sexual behavior exist and that these d...

Young novice drivers constitute a major public health concern due to the number of crashes in which they are involved, and the resultant injuries and fatalities. Previous research suggests psychological traits (reward sensitivity, sensation seeking propensity), and psychological states (anxiety, depression) influence their risky behaviour. The relationships between gender, anxiety, depression, ...

The current study examined whether the association between the occurrence of negative events and increased engagement in risky behavior is moderated by maladaptive and/or adaptive coping strategies. At time 1, 411 adolescents (ages 14-19) from Yue Yang, Hunan, completed self-report measures assessing coping strategies, engagement in risky behaviors, and the occurrence of negative events. Once a...

The consequences of risky sexual behavior are of public concern. Adolescents contribute disproportionately to negative consequences of risky sexual behavior. However, no research has examined the neural correlates of impulse control and real-world engagement in risky sexual behavior in this population. The aim of the present study was to examine this question. Twenty sexually active adolescents...
