Functional imaging studies examining the neural correlates of risk have mainly relied on paradigms involving exposure to simple chance gambles and an economic definition of risk as variance in the probability distribution over possible outcomes. However, there is little evidence that choices made during gambling tasks predict naturalistic risk-taking behaviors such as drug use, extreme sports, ...

The HIV/AIDS knowledge, attitudes, and sexual risk-taking behaviors of a sample of African-American and Caribbean college were investigated. The study also explored the relationship between the women’s self-esteem, self-efficacy, sexual communication, and religiosity and their HIV knowledge, attitudes, and risk behaviors. Findings revealed that while both groups of women were fairly knowledgeab...

health education in schools is one of the most effective ways of promoting health in a society. studies have shown the effectiveness of health interventions aimed at improving students' knowledge, attitude, and behaviors about health issues. the aim of this study was to evaluate health issues in primary school textbooks in iran.in school year 2010-2011, the contents of all primary school textbo...

As adult humans, we are continuously faced with decisions in which proper weighing of the risk involved is critical. Excessively risky or overly cautious decision making can both have disastrous real-world consequences. Weighing of risks and benefits toward decision making involves a complex neural network that includes the dorsolateral prefrontal cortex (DLPFC), but its role remains unclear. R...

This study implemented a risk-taking task during fMRI to probe the brain circuitry involved in risk-taking decision-making in 12 healthy control subjects. Partially supporting the initial hypotheses, deliberation prior to selection of safe relative to risky responses generated greater activation in the inferior frontal cortex, superior temporal gyrus, and middle temporal gyrus; and deliberation...
