From an evolutionary perspective, human risk-taking behaviors should be viewed in relation to evolutionarily recurrent survival and reproductive problems. In response to recent calls for domain-specific measures of risk-taking, we emphasize the need of evolutionarily valid domains. We report on two studies designed to validate a scale of risky behaviors in domains selected from research and the...

There are a variety of reasons someone might engage in risky behaviors, such as perceived invulnerability to harm or a belief that negative outcomes are more likely for others than for oneself. However, these risk-taking biases are often measured at a decision-making level or from the developmental perspective. Here we assessed whether or not risk-taking influenced perceptual judgments associat...

The present study (N = 86) sought to evaluate a laboratory-based behavioral measure of risk taking (the Balloon Analogue Risk Task; BART) and to test associations between this measure and self-report measures of risk-related constructs as well as self-reported real-world risk behaviors. The BART evidenced sound experimental properties, and riskiness on the BART was correlated with scores on mea...

Findings from a quantitative review of the empirical research literature on normal personality and sexual risk taking are reported. The review focuses on domains identified in major models of normal personality representing the psychobiological and taxonomic perspectives. Focal sexual risk-taking behaviors were number of partners, unprotected sex, and high-risk sexual encounters (e.g., sex with...

During the adolescent period, they experience rapid physical, emotional, cognitive developments while they establish their lifestyle and habitual routines that strongly influence adult health and life. Recent rapid economic growth in Korea, and the earlier onset of physical, sexual, and psychological maturation of adolescents, has resulted in changes in the health status of adolescents from man...

OBJECTIVE This study compared boys' with girls' hazard-directed behaviors at home when the mother was present and absent from the room. METHODS Videos were coded for how children reacted to a contrived burn hazard ('Gadget'), maternal verbalizations to children about the hazard, and children's compliance with directives to avoid the hazard. Children's behavioral attributes (risk-taking tenden...

BACKGROUND Since 2011, we have witnessed the rise of 'dark net' drug marketplaces known as cryptomarkets. Cryptomarkets operate on the same model as eBay as they provide a platform where authorized vendors can set up a virtual shop and place listings. Building on a growing body of literature that seeks to understand cryptomarket participants, this paper seeks to explain the decision of cryptoma...

BACKGROUND Older adults face important risky decisions about their health, their financial future, and their social environment. We examine age differences in risk-taking behaviors in multiple risk domains across the adult life span. METHODS A cross-sectional study was conducted in which 528 participants from 18 to 93 years of age completed the Domain-Specific Risk-Taking (DOSPERT) scale, a s...

Neurodevelopmental theories of risk behavior hypothesize that low behavioral control in combination with high reward sensitivity explains adolescents' risk behavior. However, empirical studies examining this hypothesis while including actual risk taking behavior in adolescence are lacking. In this study we tested whether the imbalance between behavioral control and reward sensitivity underlies ...

Previous research suggests that social comparisons affect decision making under uncertainty. However, the role of the length of the social interaction for this relationship remains unknown. This experiment tests the effect of social comparisons on financial risk taking and how this effect is modulated by whether social encounters are sporadic or repeated. Participants carried out a computer tas...
