Visual Working Memory Impairs Visual Detection: A Function of Working Memory Load or Sensory Load?

We performed four experiments to examine how different types of Load influence visual detection. Experiment 1 manipulated the retention time of the memory array while keeping the VWM load constant, revealing reduced visual detection along with retention time. Experiments 2 and 3 manipulated the VWM load while maintaining a constant sensory load, and visual detection was not affected. Experiment 4 affirmed that the findings in Experiments 1–3 were reliable.

本研究共进行四次实验，旨在探究不同类型的负荷如何影响视觉检测。实验一通过操控记忆阵列的保持时间，同时保持工作记忆负荷恒定，揭示了随着保持时间的增加，视觉检测能力呈现下降趋势。实验二和三在保持感官负荷恒定的条件下，操控工作记忆负荷，结果显示视觉检测能力未受到影响。实验四证实了实验一至三的发现具有可靠性。
