Humans are remarkably limited in: (i) how many control-dependent tasks they can execute simultaneously, and (ii) how intensely they can focus on a single task. These limitations are universal assumptions of most theories of cognition. Yet, a rationale for why humans are subject to these constraints remains elusive. This feature review draws on recent insights from psychology, neuroscience, and machine learning, to suggest that constraints on cognitive control may result from a rational adaptation to fundamental, computational dilemmas in neural architectures. The reviewed literature implies that limitations in multitasking may result from a trade-off between learning efficacy and processing efficiency and that limitations in the intensity of commitment to a single task may reflect a trade-off between cognitive stability and flexibility.

对认知控制能力的限制合理化

人类在以下方面受到显着限制:(i)他们可以同时执行多少依赖控制的任务,以及(ii)他们专注于单个任务的强度。这些限制是大多数认知理论的普遍假设。然而,人类为何受到这些限制的理由仍然难以捉摸。本专题回顾借鉴了心理学、神经科学和机器学习的最新见解,表明对认知控制的限制可能源于对神经架构中基本的计算困境的合理适应。审查的文献表明,多任务处理的限制可能是由于学习效率和处理效率之间的权衡,而对单一任务的承诺强度的限制可能反映了认知稳定性和灵活性之间的权衡。
