Behavioural information (stopping position, outcomes, and agency ratings) and mean FRN amplitude had been analysed employing hierarchical linear regression models (i.e. linear mixedeffects models). This method is advisable with unbalanced information, and allowed us to model single trial data (Bagiella et al 2000; Baayen et al 2008; Tibon and Levy, 205). Models integrated the situation as a predictor, coded as Alone 0, Together . Where relevant, Stopping Position and Outcome have been also incorporated as covariates, immediately after standardising the values within participants. All fixed effects were also modelled as participant random effects (random intercepts and slopes). Analyses were conducted making use of the lme4 package (Bates et al 204) in R Core Team (205). Parameter estimates (b) and their associated ttests (t, p), Oxytocin receptor antagonist 1 chemical information calculated utilizing the Satterthwaite approximation for degrees of freedom (Kuznetsova et al 205), are presented to show the magnitude on the effects, with bootstrapped 95 CIs (Efron and Tibshirani, 994). Moreover, we analysed behavioural data (proportion of trials, agency ratings, and mean outcomes) from trials in which the marble crashed. ERP data for these trials were not analysed, however, on account of low trial numbers. Finally, for collectively trials only, we compared the proportion of trials in which the coplayer acted, relative for the marble crashing.Social Cognitive and Affective Neuroscience, 207, Vol. 2, No.Fig. 2. Behavioural final results. (a) Parameter estimates for the model predicting agency ratings, with 95 bootstrapped self-confidence intervals. Condition refers towards the impact of social context (Alone 0 vs With each other ), such that a unfavorable parameter estimate denotes a loss of agency in the Together situation. (b) Imply agency ratings for the two experimental conditions, displaying a important reduction in agency ratings in With each other trials. (c) Mean position at which participants stopped the marble for the two experimental circumstances, displaying a substantial delay of actions in Together trials. Error bars show standard error on the mean.To verify no matter whether participants could have normally reported significantly less control within the with each other situation, agency ratings have been analysed specifically in trials in which the marble crashed. Agency ratings had been modelled by the social context, the outcome, and their interaction. When the marble crashed, results showed that only the outcomehow quite a few points have been lostinfluenced agency ratings [b two.28, t(25.07) two.25, P 0.034, 95 CI (0.39, 4.37)], with higher ratings associated with smaller sized losses. Social context no longer predicted agency ratings [b 0.36, t(25.57) 0.23, P 0.82, 95 CI (.52, three.55)], and there was no considerable social context by outcome interaction [b 0.47, t(26.72) 0.30, P 0.77, 95 CI (.66, three.70)]. We additional checked that based on the task style, outcomes didn’t differ, on average, across social contexts [Alone: mean five.06, SD two.92; With each other: mean five.four, SD 3.29; paired samples ttest: t(26) 0.38, P 0.7]. Thus, the relation amongst agency ratings and social context described earlier was particularly connected to these trials in which the participant effectively acted. To completely characterise participants’ behaviour inside the activity, we also analysed quantity of trials in which the marble crashed, and in which the `Other’ agent acted rather (in the with each other condition). The marble crashed considerably far more frequently within the alone condition (mean 20.47 ,.
