现实场景典型空间位置关系客体的解码效应

Decoding Effect of Objects of Typical Spatial Position Relations in Real-World Scenes

通过探讨典型空间关系客体对中单个客体的视觉工作记忆,考察空间位置关系的解码特征和主动客体记忆优势。结果发现:(1)当客体以符合空间位置关系方式呈现时,记忆更准确;(2)符合空间位置关系条件下单个客体提取反应时更长,上方客体反应时更短,记忆更准确;(3)兼具空间位置关系与动作关系客体对中的主动客体记忆正确率更高。结果表明,现实场景客体空间分组中单个客体提取时存在解码现象和顺序效应,对现实中的上方与主动客体存在加工偏好。

This study investigated the attributes of group coding and decoding of spatial position relations by testing the VWM(visual working memory) of a single object in a typical spatial relationship object pair in real-world scene. The findings of four experiments were as follows. First, when the object was presented in a way consistent with the spatial position relationship of the real scene, the VWM accuracy of a single object was higher. Second, under the condition of conforming to spatial position relationship, the extraction reaction time of a single object was longer, and the response time of the upper object was shorter. Moreover, the memory accuracy of the upper object was higher. Third, the active objects in the object pairs with both spatial and action relations had higher accuracy. In conclusion, there are decoding phenomena and retrieval order effects when extracting a single object in the object space grouping of real scenes, and the upper object and the active object have advantages on the VWM.
