This study examined age differences in collaborative inhibition and the role of inter-subjectivity, collective information sampling (CIS) and collaborative inhibition for the collaborative recall of shared and unshared information in groups of 7- and 9-year-old children. Three-hundred and thirteen 7- and 9-year-old children recalled memorized wordlists either in real or nominal groups of three. All group members either recalled the same items, or each group member was given some unique items. Nine-year-olds, but not 7-year-olds, recalled significantly more items in nominal than real groups, a phenomenon called collaborative inhibition. Groups whose interactions were characterized by higher numbers of inter-subjective exchanges recalled fewer words than groups low in inter-subjectivity. In both age groups, a higher proportion of shared compared with unshared information was recalled consistent with processes of CIS. However, 7-year-olds recalled more unshared items than predicted, suggesting that collaborative inhibition additionally contributes to the recall of shared and unshared items.
本研究考察了合作抑制的年龄差异，以及主体间性、集体信息取样 (CIS) 和合作抑制在 7 岁和 9 岁儿童小组合作回忆共享和非共享信息中的作用。313 名 7 岁和 9 岁的儿童在真实或名义的三人小组中回忆记忆中的单词列表。所有小组成员要么回忆相同的项目，要么每个小组成员都有一些独特的项目。9 岁的儿童，而不是 7 岁的儿童，在名义小组中比在真实小组中回忆出的项目明显更多，这一现象被称为合作抑制。互动中具有较高主体间交流次数的小组比主体间性较低的小组回忆的单词更少。在两个年龄组中，与非共享信息相比，共享信息的比例更高，这与 CIS 过程一致。然而，7 岁的儿童回忆的非共享项目比预测的要多，这表明合作抑制还会影响共享和非共享项目的回忆。
