以往的研究表明，适应性视觉工作记忆（VWM）训练可以提高VWM容量。然而，目前尚不清楚是否观察到的训练效果与积极控制组相比，是否培训将不仅适用于VWM的数量，但也VWM的质量，以及是否培训效果将转移到其他VWM任务。本研究以主动控制组为对照，探讨了VWM-量训练对VWM-质训练和VWM-量训练对VWM-质训练的迁移效应。每个训练组进行一周的VWM数量或质量的变化检测任务，而积极的控制组进行视觉搜索任务。结果表明，VWM量训练提高了VWM质量在后测比前测和积极控制组相比。VWM质量的培训也增加了VWM数量比前测试，虽然增加的VWM数量在后测试并不显着高于积极控制组。尽管VWM质量培训对VWM数量的转移效应较弱，但目前的结果支持VWM培训对VWM数量和质量的转移效应。调整后的适应性训练将提高有限的资源在VWM数量和质量上的配置。
Previous studies have indicated that adaptive visual-working-memory (VWM) training could increase VWM capacity. However, it is still unclear whether a training effect is observed in comparison with an active control group, whether the training would apply not only to VWM quantity but also to VWM quality, and whether the training effects would transfer to other VWM tasks. The present study investigated the transfer effect of VWM-quantity training to VWM quality and that of VWM-quality training to VWM quantity in comparison with an active control group. Each training group performed change detection tasks for either VWM quantity or quality for a week, whereas the active control group performed a visual-search task. The results indicated that VWM-quantity training increased VWM quality at post-test over the pre-test and compared to the active control group. VWM-quality training also increased VWM quantity over the pre-test, although the increased VWM quantity at post-test was not significantly higher than in the active control group. Although the transfer effect of VWM-quality training to VWM quantity was weak, the present results support a transfer effect of VWM training to VWM quantity and quality. Adjusted adaptive training of VWM would enhance the allocation of limited resources for VWM quantity and quality.
