a cross-sectional study with children's and parents' self-completed questionnaires was carried out to evaluate parents' ideas on children's risk-takjng behaviours and children's risky activities after school hours by age (7 and 9 years) and sex. nine elementary schools were randomly selected and 476 puphs aged seven and nine years and 471 parents were studied. most pare...

• Risk-taking is a multifactorial construct that can be dissociated into economic risk and ambiguity, each supported by distinct neural mechanisms. How ambiguity aversion develops over adolescence remains largely unknown. Ambiguity relate to everyday risk-taking in different ways. We propose renewed focus on research adolescent risk-taking. Popular culture often portrays as period of peak risk-...

The main idea of this paper is to identify the determinant factors decisions associated with risk Colombian small-scale coffee growers. Through a survey from selected sample growers, classified by region and size,we propensity confidence in management instruments. With data, we build two taxonomies: first one, taxonomy; second instruments taxonomy. these results, six unobservable constructs thr...

In a national youth sample, the propensity to use substances was more strongly related to motor vehicle crashes than use of any specific substance studied (cigarette, alcohol, marijuana). Substance use propensity was associated with sensation seeking, suggesting that increased crash risk for these youth is likely a result of general risk-taking tendencies.

The existence of consistent individual differences in behaviour ('animal personality') has been well documented in recent years. However, how such individual variation in behaviour is maintained over evolutionary time is an ongoing conundrum. A well-studied axis of animal personality is individual variation along a bold-shy continuum, where individuals differ consistently in their propensity to...

Background Studies have described the externalizing (e.g., antisocial propensity) and internalizing (e.g., anxiety, depression) characteristics of driving while impaired (DWI) recidivism. However, the respective contribution of those characteristics to recidivism risk and their underlying mechanisms are still unknown. Cortisol, a stress hormone, is a biomarker underlying various high-risk chara...
