“Deconstructing neural predictors of risky choice”!
Take-home point :
At least two systems (not one) predict risky choice — but both are affective! ( #neuroscience )
https://academic.oup.com/pnasnexus/advance-article/doi/10.1093/pnasnexus/pgaf204/8168828
Other key points :
• Neural predictors of risky choice can be triply dissociated from neural correlates of sensory input and motor output.
• Predictors generalize across samples, tasks, and analyses (a priori and post-hoc)
• Predictors also account for individual differences in risky choice within the lab, as well as debt beyond the lab.
• Findings robustly support a #BrainAsPredictor account of risky choice of gambles (if you don't blow out your signal in the middle of the brain with #multiband#FMRI acquisition, see Study 4)
Spearheaded by the unstoppable Leili Mortazavi with Elnaz Ghasemi and Charlene C. Wu , this culminates > 15 years of work!
The findings imply that some #FMRI findings are more robust than commonly thought (with respect to reliability, validity, and generalizability).
