This study extends previous research and examines whether working memory (WM) is associated with multiple measures of concurrent social functioning (peer rejection, overall social competence, relational aggression, physical aggression, and conflict resolutions skills) in typically developing fourth- and fifth-grade children (N=116). Poor central executive WM was associated with both broad social impairments (peer rejection and poor overall social competence) and specific social impairments (physical aggression, relational aggression, and impaired conflict resolution skills); poor verbal storage was associated only with greater peer rejection, and spatial storage was not associated with any measures of social impairment. Analyses also examined whether specific impairments in aggressive behavior and conflict resolution skills mediated the association between central executive and broad measures of social functioning. Greater physical aggression and impaired conflict resolution skills were both significant mediators; relational aggression was not. Implications for theory and future research are discussed.
本研究扩展了先前的研究，考察了工作记忆（WM）是否与多项同时进行的社交功能（同伴拒绝、整体社交能力、关系攻击、身体攻击和冲突解决技能）相关联，对象为典型的四至五年级儿童（N=116）。中央执行 WM 较差与广泛的社交障碍（同伴拒绝和整体社交能力差）和特定的社交障碍（身体攻击、关系攻击和冲突解决技能受损）相关；言语存储较差仅与更多的同伴拒绝相关，而空间存储与任何社交障碍测量都不相关。分析还检验了攻击性和冲突解决技能的特定障碍是否在中央执行与广泛的社交功能测量之间的关联中起中介作用。更大的身体攻击和受损的冲突解决技能都是重要的中介因素；关系攻击则不是。讨论了对理论和未来研究的启示。
