The answer is yes! But the effect sizes were not huge. We argued that the utility of online RL tasks was not to replace EMA or clinical surveys, but to probe the mechanisms of affective variability.

We used a Bayesian model to parse affective variability into:
⚡ noise (reactivity to recent rewards)
🌊 volatility (sustained responses to past rewards)
We asked whether affective noise and volatility in the RL task distinctly map onto their counterparts in EMA.
