摘要
实验采用n-back范式,考察了视觉工作记忆负荷与反应时、辨别力和主观评价的关系,以及空间位置记忆负荷与图形记忆负荷的差异。结果发现,随着记忆负荷的增大,反应时延长,辨别力降低,主观负荷提高。视觉图形记忆任务的负荷水平高于视觉空间位置记忆任务的负荷水平;同时也为视觉图形记忆和视觉空间记忆具有不同的加工过程提供了证据。
Focus on the effects of visual working memory load on response time, discriminability and subjective evaluation, the visual spatial working memory and the visual object memory were compared in the n-back paradigm in which the memory load varied from 1 to 3. As the memory load increased, the response time and the subjective mental workload increased as well, and the discriminability decreased. The load was higher in the abstract geometrical figure matching task than in the visual spatial matching task. This experiment evidenced that these two tasks had different processes.
