摘要/Abstract


摘要: 信息超载是指需要处理的信息量大于信息加工的能力。信息超载会降低决策质量, 延长决策时间, 降低决策满意度, 引起慢性压力。信息超载损害决策的机制可以从有限的注意力资源和工作记忆资源来解释。在信息超载条件下, 一方面用于过滤和控制信息的注意力资源总量被快速消耗, 注意力资源的分配和利用受到无关信息的干扰, 信息得不到高效加工; 另一方面负责保持和加工信息的工作记忆在限定时间内不能充分加工海量信息, 进而损害决策绩效。未来可以运用眼动赋权法探索信息超载下的信息加工模式; 发展意识思维和无意识思维的动态耦合模型指导个体减轻信息超载; 探索运用智能代理和交互记忆系统缓解组织中的信息超载。
