Perceptions of moral character modulate the neural systems of reward during the trust game

Delgado, M R, Frank, R H, Phelps, E A·2005·Nature Neuroscience

Abstract

Studies of reward learning have implicated the striatum as part of a neural circuit that guides and adjusts future behavior on the basis of reward feedback. Here we investigate whether prior social and moral information about potential trading partners affects this neural circuitry. Participants made risky choices about whether to trust hypothetical trading partners after having read vivid descriptions of life events indicating praiseworthy, neutral or suspect moral character. Despite equivalent reinforcement rates for all partners, participants were persistently more likely to make risky choices with the 'good' partner. As expected from previous studies, activation of the caudate nucleus differentiated between positive and negative feedback, but only for the 'neutral' partner. Notably, it did not do so for the 'good' partner and did so only weakly for the 'bad' partner, suggesting that prior social and moral perceptions can diminish reliance on feedback mechanisms in the neural circuitry of trial-and-error reward learning.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Decisions to cooperate with another person are influenced by information learned about the person thus far.

    “Decisions to cooperate with another person are colored by the information we have learnt about the person thus far.”
  • Ventral striatum activity does not distinguish between reciprocated versus non-reciprocated cooperation to the same degree when we have a prior (good or bad) first impression of the partner compared to when we have a neutral first impression of the partner.

    “Furthermore, ventral striatum activity does not distinguish between reciprocated versus non-reciprocated cooperation to the same degree when we have a prior (good or bad) first impression of the partner compared to when we have a neutral first impression of the partner 78.”
  • Prior reputation of a partner alters striatum responses to reciprocated or non-reciprocated cooperation.

    “Further research utilizing cooperative economic games has shown that the prior reputation of a partner alters striatum responses to reciprocated or non-reciprocated cooperation and influences decisions to cooperate or not 75–79.”
  • Prior reputation of a partner influences decisions to cooperate or not.

    “Further research utilizing cooperative economic games has shown that the prior reputation of a partner alters striatum responses to reciprocated or non-reciprocated cooperation and influences decisions to cooperate or not 75–79.”
  • Once we initially make a positive impression of someone, we are more likely to continue cooperating with that person even when they fail to consistently reciprocate our cooperation.

    “Once we initially make a positive impression of someone, we are more likely to continue cooperating with that person even when they fail to consistently reciprocate our cooperation.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
