Subclaims¶

q2 i? Striatal prediction-error signals track others' actions and outcomes in ultimatum, trust, and reciprocity games, and persist when learning is purely observational with no added payoff for social learning. → Jessica Joiner 2017

q2 · i? · review · r3

Review of human fMRI studies of observational and economic-game learning. The striatum correlates with prediction errors about partner offers in an ultimatum game, trust learning in the caudate nucleus, and interpersonal prediction errors under pure observation.

"if added payoff for social learning is removed, so that only pure observation of others is necessary for the task, an interpersonal prediction error still occurs in the striatum."

Related Claims¶

• Prefrontal cortex separates other-referenced prediction errors by subtype: dlPFC for other's actions, vmPFC for other's outcomes — related
• Observer rats show ventral striatal dopamine release to another's reward, weaker than for own reward — a narrower finding that bears on this claim
• Anterior cingulate gyrus specializes in other-referenced social valuation and prediction errors, dissociable from the sulcus — related
• Mentalizing-network regions (TPJ, STS, dmPFC, MTG) signal social prediction errors beyond ToM tasks — related
• Brain responds similarly to prediction errors for human and slot-machine partners' generosity — a narrower finding that bears on this claim
