AIC: Akaike information criterion; BIC: Bayesian information criterion; IOS: inclusion of other in the self.

All models included a random effect for participants. The Akaike information criterion (AIC), Bayesian information criterion (BIC), variance explained by fixed effects (marginal R²), and variance explained by fixed and random effects (conditional R²) are provided. χ² and p values refer to model comparisons against models indicated in parentheses using likelihood ratio tests. For both dependent variables, model M5 describes the data best (marked in bold).
