Whether multiple representations in visual working memory (VWM) can simultaneously guide attention is controversial. The multiple-item-template (MIT) hypothesis holds that multiple VWM representations can be active to guide visual attention simultaneously, whereas the single-item-template (SIT) hypothesis argues that only one VWM representation can interact with attention at a time. Recent study form (Fan et al., Acta Psychologica 192:126–137, 2019) provided strong evidence on MIT through the method of comparing the patterns of guidance effects in different experimental conditions. In the present study, we aimed to reexamine SIT and MIT by sharing a new condition wherein two search distractors match the single memory representation, using the original Fan et al. tilted-line search task. The guidance effect when two colored-shapes were held in VWM and both were present as distractors in the search array were observed and equal to that when the single colored-shape in VWM matched two of the distractors, which is consistent with the hypothesis of MIT. Moreover, the comparison on the degree of linear fitting between the actual data and two hypothesized models according to SIT and MIT showed that the Model of MIT fits the data best with a higher R² of 0.125.

视觉工作记忆（VWM）中的多种表征是否可以同时引导注意力是有争议的。多项目模板 (MIT) 假设认为多个 VWM 表示可以同时激活以引导视觉注意力，而单项目模板 (SIT) 假设认为一次只有一个 VWM 表示可以与注意力交互。最近的研究表格（Fan et al., Acta Psychologica 192:126–137, 2019）通过比较不同实验条件下的引导效果模式的方法，为 MIT 提供了强有力的证据。在本研究中，我们旨在通过共享一个新条件来重新检查 SIT 和 MIT，其中两个搜索干扰项匹配单个记忆表示，使用原始 Fan 等人。斜线搜索任务。观察到两个彩色图形在 VWM 中同时作为干扰物出现在搜索阵列中时的引导效果，与 VWM 中的单个彩色图形匹配两个干扰物时的引导效果相同，这与麻省理工学院的假设一致. 此外，根据 SIT 和 MIT 对实际数据与两个假设模型的线性拟合程度的比较表明，MIT 模型与数据的拟合最佳，具有较高的 R0.125 中的^2个。
