To investigate whether socially shared retrieval-induced forgetting effect existed in children,the study examined the developmental characteristics of children's socially shared retrieval-induced forgetting by selecting five age groups.Specifically,each group had 30 children(9,10,11,and 12 years old),along with 30 college students(21 years old)as the adult group.A 5(age:9,10,11,12,21)×3(item type:Rp+,Rp-,Nrp)mixed design was adopted in the experiment.The results revealed that socially shared retrieval-induced forgetting occurred in all five age groups,and children in each group performed the same as the adult group for the magnitude of the SS-RIF effect.The socially shared retrieval-induced forgetting is stable in children aged 9 to 12 years.
