  1. Self-bias (self-related trials against neutral-stranger trials) were obtained in experiments 1–3, and a similar advantage toward the best friend was obtained in experiment 4 and 5. Partner-advantage refers to partner-related trials against neutral-stranger trials. Significant results are shown in bold font
