“…In addition, 6-year-old children also shared more with an anonymous other than with a disliked peer (Moore, 2009;Paulus & Moore, 2014). Other cross-sectional studies do not support this differentiation during elementary school as they found that children aged 9-12 did not differentiate in the amount of resources shared with a friend, disliked, and anonymous recipient (Gü rog lu et al, 2014), but adolescents from 12 years and older did (Güroglu et al, 2014;van de Groep et al, 2019). Thus, results from previous cross-sectional studies were quite mixed on whether elementary school children share more with friends, compared to anonymous and disliked recipients, and how sharing behavior with friends, anonymous, and disliked peers develops during elementary school.…”
