Working Memory

165
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

科学领域:

  • 认知神经科学 认知神经科学
  • 社会心理学 社会心理学
  • 人类行为人类行为.

背景情况:

  • 相信与他人协调行动取决于思想理论 (ToM).
  • 具体的认知过程在协调行动中的因果作用仍然不清楚.
  • 工作内存负载已被证明会在单个任务中损害ToM.

研究的目的:

  • 调查工作记忆负载在两人协调中的因果作用.
  • 检查认知负载对协调任务中的性能和神经测量的影响.

主要方法:

  • 使用脑电图 (EEG) 来测量P3振幅 (工作记忆编码) 和大脑间同步 (IBS).
  • 采用计算机化协调任务,其中二极管选择抽象图像.
  • 使用并发的n-back任务 (高负载与低负载) 操纵工作内存负载.

主要成果:

  • 高工作内存负载显著降低了协调性能和P3振幅.
  • 观察到P3振幅和协调性能之间存在显著的关系.
  • 脑间同步 (IBS) 没有受到负载的影响,也没有与性能相关.

结论:

  • 工作记忆在两个人的协调中起着因果作用.
  • 这些发现挑战了社会调整是特定于领域的,独立于成年人执行控制的观念.
