Here, in a pre-registered study (Stage 1 Registered Report: ), we investigate the opposite link: How outcome ownership influences responsibility attributions in a social context. Previous research focused on how someone's responsibility determines the outcome they deserve, for example, whether they are rewarded or punished. ** p<0.01īackground: Responsibility judgements have important consequences in human society. Bottom panel: motor preparation signal at the peak of the effect at 516ms for the private vs the social context. The blue patch indicates the time where the button was pressed based on reaction times and their standard errors. The black line indicates timepoints where the parameter estimate is significant against zero (cluster one-tailed pcorr<0.05). Negative parameter estimates indicate lower motor preparation in the Social vs Private context, which is significant around 500 ms after gambles onset. b) Stimulus-locked motor lateralization: Top panel: Parameter estimate of the regression of motor preparation signal against the Social vs Private regressor. Bottom panel: Response-locked motor lateralization: motor preparation from 0.8 second before until response measured with the power of 8-32Hz Frequencies in ipsilateral minus contralateral electrodes relative to the hand pressed locked to the motor response in all four different contexts. a) Topography showing the mean power of 8-32Hz frequencies at 100ms before the motor response for conditions where participants answered with the Left Hand minus the Right Hand and the associated estimated sources. Motor preparation signals are modulated by responsibility context. Together, these results show that sharing responsibility with others reduces agency through an influence on pre-outcome motor preparation and post-outcome processing, affording an opportunity for flexibility in credit for positive outcomes. A boost in responsibility for positive outcomes in social contexts was associated with increased activity in regions related to social and reward processing. During social decisions, prior to outcome revelation, a motor preparation signature at 500ms after stimulus onset was attenuated. An MEG outcome processing effect was reduced as a function of decreasing responsibility at 200ms post outcome onset and centred over parietal and precentral brain regions. Participants performed a reward-based learning decision-making task in contexts where their sense of responsibility over outcomes decreased with group size. Here we investigated the neural expression of this effect using magnetoencephalography (MEG). Distributing responsibility across several individuals in social decisions helps minimize a burden of responsibility for consequences of decisions.
