How the opinion of others affects our valuation of objects.

Campbell-Meiklejohn DK, Bach DR, Roepstorff A, Dolan RJ, Frith CD - Curr. Biol. (2010)

Bottom Line: It is known that the magnitude of activity in the ventral striatum reflects the value of reward-predicting stimuli.We show that social influence on the value of an object is associated with the magnitude of the ventral striatum response to receiving it.Influence at such a low level could contribute to rapid learning and the swift spread of values throughout a population.

Main Effects(A) Object outcome [RSS + RAS] – [RSA + RAA]. Highlighted anatomy was more active when the participant received a token for his or her originally preferred song relative to receiving one for the alternative.(B) Review outcome [RSS + RSA] – [RAS + RAA]. Highlighted anatomy was more active when both reviewers agreed with the subject's preference compared to when they both preferred the alternative. Green maps show activation of the same contrast at a slightly reduced cluster definition threshold (Z > 2.0, p < 0.05). See also Figure S2 and Table S2.(C) Unanimous reviewer agreement [RSA + RSA] – [RSPLIT]. Highlighted anatomy is more active when both reviewers agree with the subject than when one chooses the subject's song and the other chooses the alternative.(D) Unanimous reviewer disagreement [RAA + RAS] – [RSPLIT]. Highlighted anatomy is more active when both reviewers disagree with the subject compared to when one chooses the subject's song and the other chooses the alternative. Unless otherwise specified, all activations are whole-brain cluster-corrected Z statistic maps (Z > 2.3, p < 0.05), which were overlaid onto the standard MNI brain. Coordinates of brain sections are indicated in MNI space (mm).

Mentions: Subjects randomly received a token for one song on each trial (subject's preference or an alternative). Receiving a token for the preferred song compared to receiving one for the alternative elicited more blood oxygenation level-dependent (BOLD) activity in the ventral striatum (peak MNI coordinates [mm]: 14, 10, −8; −16 16, −2) (Figure 2A), left lateral prefrontal cortex (peak −46, 40, 4), and posterior cingulate cortex (peak −2, −36, 34).
