New Cogsci preprint, "Introducing the Extinction Gambling Task," with Adam Harris, David Kellen, and.@HenrikSingmann. We introduce a risky choice task in which participants can lose their (entire) bonus pay when choosing the risky option and drawing the extinction event.

Using this design, we again replicated the transfer effects on moral convictions and donation decisions between the two independent studies. For more details see our preprint:

Lastly, to address potential demand characteristics, we recruited participants for a study with the learning task and then recruited the same participants for a second study with the transfer measures. Ps did not know that the two studies were related (more details in Methods).

The learning of those participants that are best captured by metacognitive learning transferred to incentive-compatible donation decisions and measures of moral convictions.

Further, using an ensemble of computational models, we show that many participants learn about decision strategies in general (metacognitive learning) rather than specific behaviors.

Across four experiments, we found that participants adjusted their decision-making strategies (reliance on rules vs. cost-benefit reasoning) based on which produced better consequences.

We outline a theory of how strategy selection learning shapes moral decision-making, implement it using computational models, and test it using a novel paradigm involving realistic trolley-type dilemmas with outcomes.

We updated our preprint on moral learning, now titled "Metacognitive Learning from Consequences of Past Choices Shapes Moral Decision-Making," with three new experiments and computational modeling to capture differences in individual learning styles. @vanessachg_ @FalkLieder
