此摘要是机器生成的。

自我消耗,或在苛刻的任务后自我控制能力降低,可能源于注意力增加的努力. 在初始任务中瞳孔直径升高 (PD) 预测了随后的自我控制任务的表现较差,揭示了生理机制.

关键词:
自我消耗 - 消耗的自我.眼球追踪器 眼球追踪器这里是Locus coeruleus的地方.上腺素 (Norepinephrine) 是一种可以瞳孔测量术 (pupillometry) 是指用眼睛测量一个孩子的眼睛.自制是一种自我控制.

科学领域:

  • 认知心理学 认知心理学
  • 神经科学是一个神经科学.

背景情况:

  • 自制任务可能会损害后续任务的表现,这种现象被称为自我消耗.
  • 驱动自我消耗的潜在机制,特别是注意力努力的作用,仍然不完全理解.

研究的目的:

  • 调查通过瞳孔测量测量的注意力努力在自我消耗效应中的作用.
  • 检查初始自我控制任务中的瞳孔直径 (PD) 与随后的认知控制任务中的表现之间的关联.

主要方法:

  • 参与者接受了高或低需求的注意力任务 (自我消耗操纵).
  • 瞳孔测量用于测量两个任务期间瞳孔直径 (PD) 的持续和相位变化.
  • 对随后的Stroop任务的表现进行了评估,以测量认知控制缺陷.

主要成果:

  • 在高需求条件下的参与者在初始任务期间显示出更大的持续PD.
  • 在操纵阶段持续增加的PD预测Stroop任务的准确性更差,这表明通过持续关注的间接途径.
  • 在操纵过程中,较大的阶段性PD反应独立预测Stroop性能较差,表明通过暂时的注意力控制直接途径.

结论:

  • 注意力努力,反映在瞳孔直径的变化,在自我消耗中发挥着重要作用.
  • 持续的和短暂的注意力增加都可能导致认知控制障碍在苛刻的任务后.
  • 这些发现为自我控制和自我消耗的生理基础提供了神经科学的见解.
