Figure 1. Item scores of “offering to share” at t₀ (4-to-5-years old; in grey) and t₁ (current period; mean age: 129.9±55.8 months old; in black) for G_0A (group with no pet in the family), G_pet (group with a pet arriving after the child’s 5^th birthday), G_0B (group with no pet in the family) and G_alw (group always with at least one pet at home since birth).

Higher the score, more significant was the “offering to share” (e.g. sharing food or toys with parents or other children).
