The psychology of risk taking: Toward the integration of psychometric and neuropsychological paradigms

The prevention of counterproductive or antisocial risk taking is a research priority. Attempts to understand risk-taking behaviors are dominated by the psychometric and neuropsychological paradigms, which have developed in relative isolation. Previous studies indicate that risk taking is associated with the sensation-seeking personality trait, although the relationship with impulsivity may be complex. Poor risk-related decision making is associated with lesions to the ventromedial prefrontal cortex. Further research is necessary to establish which forms of risk taking are associated with the 5-factor model of personality and may be influenced by ventromedial prefrontal cortex functioning. The relationship between risk-related decision making and personality traits is also discussed in order to provide a basis for future research adopting an integrated model of risk taking behavior.
