TL;DR: There is no convincing evidence that moderate MDMA use is associated with structural or functional brain alterations in neuroimaging measures, and the lack of significant results was associated with high methodological heterogeneity in terms of dosages and co-consumption of other drugs, low quality of studies and small sample sizes.

TL;DR: In this paper, the Balloon Analogue Risk Task (BART) was investigated and it was found that the typical implementation of this task violates the principle of representative design, thus conflicting with the expectations people likely form from real balloons, which may explain the previously observed limitations in some of the BART's psychometric properties.

TL;DR: In this paper, the authors investigate the information-integration processes underlying people's self-reports by means of cognitive modeling and examine people's cognitive representations of their risk preferences, finding that interindividual differences in self-reported risk preferences can be modeled well based on the listed aspects' properties of evidence and substantially better than using sociodemographic variables as predictors.

TL;DR: Overall, the results suggest that researchers should move away from CPT, and focus their efforts on alternative models such as DFTe, as it is able to accommodate the choice data at large in a parsimonious fashion.
