Connecting brain responsivity and real-world risk taking: Strengths and limitations of current methodological approaches
نویسندگان
چکیده
In line with the goal of limiting health risk behaviors in adolescence, a growing literature investigates whether individual differences in functional brain responses can be related to vulnerability to engage in risky decision-making. We review this body of work, investigate when and in what way findings converge, and provide best practice recommendations. We identified 23 studies that examined individual differences in brain responsivity and adolescent risk taking. Findings varied widely in terms of the neural regions identified as relating to risky behavior. This heterogeneity is likely due to the abundance of approaches used to assess risk taking, and to the disparity of fMRI tasks. Indeed, brain-behavior correlations were typically found in regions showing a main effect of task. However, results from a test of publication bias suggested that region of interest approaches lacked evidential value. The findings suggest that neural factors differentiating riskier teens are not localized to a single region. Therefore, approaches that utilize data from the entire brain, particularly in predictive analyses, may yield more reliable and applicable results. We discuss several decision points that researchers should consider when designing a study, and emphasize the importance of precise research questions that move beyond a general desire to address adolescent risk taking.

متن کاملMethodological Dimensions of Transcranial Brain Stimulation with the Electrical Current in Human
Transcranial current stimulation (TCS) is a neuromodulation method in which the patient is exposed to a mild electric current (direct or alternating) at 1-2 mA, resulting in an increase or a decrease in the brain excitability. This modi.cation in neural activities can be used as a method for functional human brain mapping with causal inferences. This method might also facilitate the treatments ...

متن کاملPrediction of Risk-Taking Behaviors Based on the Role of Perceived Social Support Components, Emotional Expression and Brain- Behavioral Systems in Addications
Introduction: The prevalence of risk-taking behaviors in communities is one of the serious health threats and has been considered in recent years due to rapid social change by health organizations, law enforcement and social policymakers. The purpose of this study was to predict risk-taking behaviors based on the role of perceived social support components, emotional expression and brain- behav...
متن کاملReconstructing the Risk–Need–Responsivity model: A theoretical elaboration and evaluation
In this paper, we examine the theoretical strengths and weaknesses of the Risk–Need–Responsivity (RNR) model of offender rehabilitation. We briefly discuss the nature of rehabilitation theories and their core components and then review the three source theories associated with the RNR Model. Following this we set out to reconstruct the RNR model in light of this analysis, essentially arguing th...
