本研究探讨了言语标记和暴露时间在新视觉模式内隐记忆中的作用。实验一采用不同的编码条件，其中两种编码条件不鼓励词语标注，第三种编码条件要求词语标注。在实验2中，通过操纵暴露时间来确定在一次1-S暴露后是否可以形成新的记忆表征。结果表明，言语标记并不是支持启动的必要条件。编码类型对内隐记忆没有影响，但对外显记忆有显著影响。此外，单次1-S暴露就足以支持启动，而较长时间的刺激暴露不会进一步增强启动。相比之下，较长的刺激持续时间可以提高再认性能。因此，这些新奇图形的启动效应可能由新获得的表征支持，而不是由先前存在的记忆表征支持。
The present study investigated the role of verbal labeling and exposure duration in implicit memory for novel visual patterns. Encoding condition was varied in Experiment 1. Two encoding conditions discouraged verbal labeling and a third required it. In Experiment 2, exposure duration was manipulated to determine whether a new memory representation could be formed after a single 1-s exposure. The results suggest that verbal labeling is not necessary to support priming. Type of encoding did not affect implicit memory, but had a pronounced effect on explicit memory. Furthermore, a single 1-s exposure was sufficient to support priming, and priming was not further enhanced by longer stimulus exposures. In contrast, recognition performance was enhanced by a longer stimulus duration. Thus, priming effects with these novel figures are likely to be supported by newly acquired representations rather than by preexisting memory representations.
