Our approach is to understand this process of learning moral values by drawing on formal computational models. We use the two distinct systems known to guide choice behavior: the habitual internalized “model-free” system, and the goal-directed planning “model-based” system.
We modeled our empathic learning experiment on a previous two-step reinforcement learning task that identifies which of the two decision-making systems has greater control in making non-social choices. This task can dissociate model-based and model-free strategies based on different predictions these strategies make on how second-stage rewards affect subsequent first-stage choices. We investigate the computational architecture for moral decision-making by introducing empathy-inducing stimuli— morphed images of faces expressing varying degrees of pain. …show more content…
Does empathy have a greater impact on decision-making by using agoal-directed planning system or by triggering an automatic and internalized dislike for actions that cause
