Risk Taking Behaviors

The relation between peer influence and risk-taking behaviors has received extensive empirical attention. However, the underlying mechanisms of whether how two-way conflicting context influences risk-taking behaviors still remain unclear. To this end, the current study used event-related potentials (ERPs) to investigate how peer competition affects risk-taking behaviors among adolescents. Twenty-four college students completed a Balloon Analogue Risk Task (BART) under two contexts: single and peer competition condition. Behavioral results showed that participants prefer risk aversion in competitive context. ERPs results showed that participants induce higher N2 under peer competition in the decision-making phase. In the feedback phase, a higher P300 was observed in single condition while a more negative feedback-related negativity (FRN) was showed after loss feedback. Results are in line with social comparison theory and reinforcement learning theory. The specific effect of peer influence on risk-taking behavior has been discussed.

Excessive risk-taking behaviors have been implicated as a potential endophenotype for substance use disorders and psychopathological gambling. However, the genetic and environmental influences on risk taking and the risk-related brain activations remain unclear. This study investigated the heritability of risk taking and the genetic influence on individual variation in risk-related brain activation. The Balloon Analogue Risk Task was used to assess individuals’ risk-taking behavior. In a sample of 244 pairs of young adult twins, we found that there was a moderate heritability (41%) of risk taking. Using voxel-level analysis, we found a moderate genetic influence on risk-related brain activation. We also found a moderate genetic correlation between risk-taking behavior and risk-related brain activation in the left insula, right striatum, and right superior parietal lobule in the active-choice condition. The present study provides important evidence for the genetic correlation between risk-taking behavior and risk-related brain activation.

Underlying Mechanisms

In the present study, we used event-related potentials (ERPs) and behavioral measurements in a peripherally cued line-orientation discrimination task to investigate the underlying mechanisms of orienting and focusing in voluntary and involuntary attention conditions. Informative peripheral cue (75% valid) with long stimulus onset asynchrony (SOA) was used in the voluntary attention condition; uninformative peripheral cue (50% valid) with short SOA was used in the involuntary attention condition. Both orienting and focusing were affected by attention type. Results for attention orienting in the voluntary attention condition confirmed the “sensory gain control theory,” as attention enhanced the amplitude of the early ERP components, P1 and N1, without latency changes. In the involuntary attention condition, compared with invalid trials, targets in the valid trials elicited larger and later contralateral P1 components, and smaller and later contralateral N1 components. Furthermore, but only in the voluntary attention condition, targets in the valid trials elicited larger N2 and P3 components than in the invalid trials. Attention focusing in the involuntary attention condition resulted in larger P1 components elicited by targets in small-cue trials compared to large-cue trials, whereas in the voluntary attention condition, larger P1 components were elicited by targets in large-cue trials than in small-cue trials. There was no interaction between orienting and focusing. These results suggest that orienting and focusing of visual-spatial attention are deployed independently regardless of attention type. In addition, the present results provide evidence of dissociation between voluntary and involuntary attention during the same task.

Core Features

AbstractRisk-taking behavior and impulsivity are core features of bipolar disorder. Whether they are part of the inherited aspect of the illness is not clear. We aimed to evaluate risk-taking behavior as a potential endophenotype for bipolar disorders, and its relationship with impulsivity and illness features. The Balloon Analogue Risk Task (BART) and Barratt Impulsiveness Scale-11 (BIS-11) were used to assess risk-taking behavior and impulsivity respectively in 30 euthymic bipolar I patients (BD), their 25 asymptomatic first-degree relatives (BD-R), and 30 healthy controls (HC). The primary BART outcome measure was the behavioral adjustment score (number of pumps after trials where the balloon did not pop minus the number of pumps after trials where the balloon popped). BD (p< .001) and BD-R (p= .001) had similar and significantly lower adjustment scores than HC. Only BD scored significantly higher on BIS-11 total (p= .01) and motor (p= .04) subscales than HC. Neither the BART, nor impulsivity scores associated with illness features. A limitation of this study is medicated patients and a heterogeneous BD-R were included. Riskiness may be a candidate endophenotype for bipolar disorder as it appears independently from illness features, presents similarly in BD and BD-R groups and differs from impulsivity.

AbstractZolpidem is a GABA (A) agonist, which is indicated for the short-term management of insomnia. Recent research provide evidence suggesting that zolpidem produces spatial working memory (WM) deficits and dependence; however, the underlying mechanisms of these effects are unknown. Since the auditory N400 component of event-related potentials (ERPS) is considered as an index of memory use of context processing, the present study focused on N400 waveform of ERPs elicited during a WM task in a case suffering from zolpidem dependence. The patterns of N400 waveform of this case were compared to the patterns obtained from healthy controls. This comparison revealed that zolpidem dependence is accompanied by reduced amplitudes located at posterior brain areas and diffuse prolongation of N400. These findings may indicate that zolpidem dependence manifests alterations with regard to the memory use of context processing, involving or affecting a wide-ranging network of the brain's structures.

Objective: ADHD in adolescents and low level of parental monitoring have been associated with increased risk-taking behavior. The present study examined whether parental knowledge of the child’s whereabouts mediates the correlations between adolescent ADHD symptoms and risk-taking behavior. Method: Ninety-two adolescents and their parents completed questionnaires assessing perceptions of parents’ monitoring, engagement in risk-taking behaviors, and ADHD symptoms. Results: Greater engagement in risk-taking behavior correlated with higher levels of ADHD symptoms and decreased parental monitoring. Mediation analysis revealed both direct effect of ADHD symptoms on risk-taking behavior and an indirect effect mediated by level of parental knowledge. Conclusion: These findings suggest that parental knowledge is negatively affected by the presence of ADHD symptoms, and may in turn lead to risk-taking behavior. The findings emphasize the need to target parenting and in particular parental knowledge of the child’s whereabouts to reduce risk-taking behaviors among youth with ADHD.
