“…Transcranial direct current stimulation is the application of a weak electrical current across a target brain region to modulate activity and establish a causal relationship between a behavior and a target brain region. tDCS modulates brain functions promoting or inhibiting neural activity in the target areas, and its molecular action has been hypothesized to involve both dopaminergic circuitries and neuroplasticity processes (Pettorruso et al, 2021 ). Compared with other brain stimulation techniques, tDCS is relatively cheaper, easy to use (Martinotti et al, 2019 ), with even fewer adverse effects (Brunoni et al, 2011 ; Aparício et al, 2016 ), painless, and noninvasive (Maréchal et al, 2017 ; Martin et al, 2017 , 2019 ; Meyer et al, 2019 ; Wang and Zhang, 2021 ; Xiong et al, 2021 ; Zhang et al, 2022b ).…”

Fairness is a hallmark of humans' ability to maintain cooperative relationships with large numbers of unrelated others. It influences many aspects of daily life, from how people share their resources with partners to how policymakers shape income distribution policy. The right temporoparietal junction (rTPJ) is a hub of the mentalizing network and it has been proposed to play a key role in guiding human reciprocal behavior; however, its precise functional contribution to fair behavior in situations of advantageous and disadvantageous inequity remains unclear. The purpose of this study was to clarify the role of the rTPJ in relation to fair behavior in situations of advantageous and disadvantageous inequity by modulating the activation of the rTPJ through transcranial direct current stimulation (tDCS). Anodal tDCS at 1.5 mA over the primary visual cortex (VC) or rTPJ was performed and participants subsequently played a binary-choice version of the Dictator Game. We found that anodal tDCS over the rTPJ increased the participants' equity choices in the disadvantageous inequity situation but not in the advantageous inequity situation. The tDCS effect is moderated by sex and, in particular, the tDCS effect increases female equity choices. The results suggest that the rTPJ plays a distinct role in inequity aversion in these two types of inequity situations.

“…By limiting stochasticity unrelated with subject-specific information, our findings are particularly meaningful for the implementation of the BART in neuroimaging studies and for the investigation of clinical and subclinical phenotypes. Future clinical research will benefit from the improvement of this psychometric instrument for detecting aberrant decision-making processes, thus allowing to accurately monitor the efficacy of treatment targeting the pathophysiology of risky behaviors ( Pettorruso et al, 2021 ). The accurate extraction of neurocognitive profiles will hopefully help guide clinicians in the selection of more personalized interventions.…”

Appropriately Tuning Stochastic-Psychometric Properties of the Balloon Analog Risk Task

The Balloon Analog Risk Task (BART) allows to experimentally assess individuals’ risk-taking profiles in an ecologically sound setting. Many psychological and neuroscientific studies implemented the BART for its simplicity and intuitive nature. However, some issues in the design of the BART are systematically unconsidered in experimental paradigms, which may bias the estimation of individual risk-taking profiles. Since there are no methodological guidelines for implementing the BART, many variables (e.g., the maximum explosion probabilities, the rationale underlying stochastic events) vary inconstantly across experiments, possibly producing contrasting results. Moreover, the standard version of the BART is affected by the interaction of an individual-dependent, unavoidable source of stochasticity with a trial-dependent, more ambiguous source of stochasticity (i.e., the probability of the balloon to explode). This paper shows the most appropriate experimental choices for having the lowest error in the approximation of risk-taking profiles. Performance tests of a series of simulated data suggest that a more controlled, eventually non-stochastic version of the BART, better approximates original risk-taking profiles. Selecting optimal BART parameters is particularly important in neuroscience experiments to optimize the number of trials in a time window appropriate for acquiring neuroimaging data. We also provide helpful suggestions to researchers in many fields to allow the implementation of optimized risk-taking experiments using the BART.
