Towards a hybrid criminological and psychological model of risk behavior: The Developmental Neuro-Ecological Risk-taking Model (DNERM)

 

Adolescents have long been characterized as the stereotypical risk-takers, due to their apparent heightened risk behavior (e.g., delinquency, substance use). Hence, the raising of the minimum age for substance use is a common legal action that presumes that limiting the exposure to substances (i.e., “risk exposure” and accordingly “risk opportunity”) will decrease such heightened adolescent risk behavior. This ecological concept of risk exposure is acknowledged in criminological models—to some extent. However, risk exposure is virtually absent from contemporary psychological models, which focus on neurodevelopment, particularly socio-affective and cognitive control development. Moreover, when theories in these disciplines do consider risk exposure, the ubiquitous developmental (i.e., age-dependent) component of this concept is overlooked. For example, in the real-word, adolescents encounter far more risk-conducive situations (i.e., risk exposure) than children, which could at least partially account for heightened adolescent risk behaviors compared to children. A meta-analysis (Defoe et al., 2015) on laboratory studies provided suggestive evidence for this assertion. Namely, this meta-analysis showed that in laboratory settings—where risk exposure is equal for all participants regardless of age—children and adolescents are generally equally susceptible to engage in risks. Hence, in the above-mentioned meta-analysis, a hybrid Developmental Neuro-Ecological Risk-taking Model (DNERM) was put forward. DNERM posits that age and cultural factors at least partially determine physical and social exposure to risk conductive situations (i.e., physical and social risk exposures). Additionally, these risk exposures predict adolescents’ risk behavior, and this association is potentially moderated by adolescents’ cognitive and affective self-control. Hence, DNERM emphasizes adolescents’ neuropsychological development within its physical- and social- ecology, which is further embedded in a cultural context. This presentation will address DNERM’s aims, which include bridging contemporary developmental psychology models with criminology models to describe the development of risk behavior during the youth period.

A taxonomy of data synthesis

As more data is shared and concerns over the replicability, reproducibility, and generalizability of psychological and other social sciences continues, more researchers aim to conduct multi-study or multi-sample research (e.g., using traditional meta-analysis, individual participant data meta-analysis [IPD-MA], or coordinated analysis). However, existing frameworks of data synthesis neither clearly differentiate different approaches or compare their convergence, unique considerations, and more. This talk has three main goals. First, I provide an overview of data synthesis methods and organize these into a taxonomy of methods of data synthesis. Second, using empirical data from 26,205 participants across 10 longitudinal studies, I provide a tutorial for estimating prospective meta-analytic and sample-specific associations between the Big Five personality traits and crystallized abilities along with four moderators of these associations across each method. Finally, I compare convergence and divergence of findings across methods. I conclude by making recommendations and providing a flow chart for choosing the most appropriate method of data synthesis given research goals, questions, and data availability.
