视觉工作记忆通过与言语相关的过程得到增强。然而，这种增强的机制尚不清楚。实验 1 通过评估发音抑制对两种版本的视觉模式 Testone 低语言编码可用性和一种高语言编码可用性的影响，研究了工作记忆语音循环的潜在贡献。缺乏互动表明语音循环不负有责任。然而，积极使用言语和视觉相结合的策略以及激活的语义知识似乎都与能力的提高有关。实验 2 评估了中央执行资源的作用。由于中枢执行抑制消除了高语言编码任务版本的好处，因此假定与情景缓冲区中多模式代码的临时维护相关的中枢执行资源似乎是与语言化相关的好处的基础。
Visual working memory is enhanced by processes related to verbalisation. However, the mechanism underlying this enhancement is unclear. Experiment 1 investigated the potential contribution of the phonological loop of working memory, by assessing the effects of articulatory suppression on two versions of the Visual Patterns Testone low and one high in availability of verbal coding. The lack of interaction suggested that the phonological loop is not responsible; however, active use of combined verbal and visual strategies, as well as activated semantic knowledge, both appear to be related to increased capacity. Experiment 2 assessed the role of central executive resources. Because central executive suppression removed the benefit of the high verbal coding task version, central executive resources, assumed to relate to the temporary maintenance of multimodal codes in the episodic buffer, appear to underlie the benefit associated with verbalisation.
