Individual differences in the nature and frequency of conflict behaviour between 18-24 month old children and their older siblings were investigated in a sample of 43 sibling pairs observed at home with their mothers. By 24 months, relatively mature behaviour such as conciliation, teasing, reference to social rules and justification for prohibition were observed. These behaviours were correlated with maternal and sibling reference to social rules and feelings 6 months earlier; physical aggression was correlated with earlier sibling physical aggression and maternal involvement. Sibling status and type of maternal intervention were not related to frequency and duration of sibling conflict.
在一项对43对兄弟姐妹及其母亲在家中进行观察的样本研究中，调查了18至24个月大的儿童与其年长兄弟姐妹之间冲突行为的性质和频率的个体差异。到24个月时，观察到了相对成熟的行为，如和解、逗弄、提及社会规则和对禁令的辩解。这些行为与6个月前母亲和兄弟姐妹对社会规则及情感的提及相关；身体攻击行为与早期兄弟姐妹的身体攻击行为以及母亲的参与度相关。兄弟姐妹的地位和母亲干预的类型与兄弟姐妹冲突的频率和持续时间无关。
