[PDF][PDF] Decisions to intervene on causal systems are adaptively selected
Proceedings of the Annual Meeting of the Cognitive Science Society, 2014•escholarship.org
How do people choose interventions to learn about a causal system? Here, we tested two
possibilities: an optimal information sampling strategy which aims to discriminate between
multiple hypotheses, and a second strategy that aims to confirm individual hypotheses. We
show in Experiment 1 that individual behavior is best fit using a mixture of these two options.
In a second experiment, we find that people are able to adaptively alter the strategies they
use in response to their expected payoff in a particular task environment.

Abstract
How do people choose interventions to learn about a causal system? Here, we tested two possibilities: an optimal information sampling strategy which aims to discriminate between multiple hypotheses, and a second strategy that aims to confirm individual hypotheses. We show in Experiment 1 that individual behavior is best fit using a mixture of these two options. In a second experiment, we find that people are able to adaptively alter the strategies they use in response to their expected payoff in a particular task environment.
