Studies of implicit memory for novel associations have focused primarily on verbal materials and have highlighted the contribution of conceptually unitized representations to such priming. Using pictorial stimuli in a perceptual identification task, we examined whether new association priming can occur at a purely perceptual level. By manipulating the spatial contiguity of stimuli, we also evaluated whether such priming requires the creation of perceptually unitized representations. Finally, we examined the status of such priming in aging. In Experiment 1, we found that spatial contiguity of stimuli is not necessary for novel pictorial association priming to emerge, although such contiguity does enhance the magnitude of associative priming. In Experiment 2, we found that new association priming is age invariant, regardless of spatial contiguity. In Experiment 3, we provide additional evidence that pictorial association priming is perceptually based. These findings expand the scope and delineate the conditions of novel association priming and inform theories about the nature of implicit memory for new associations.
对新颖联想的内隐记忆的研究主要集中在言语材料上，并强调了概念上统一的表示对这种启动的贡献。我们在知觉识别任务中使用图像刺激，以检验新的联想启动是否可以在纯粹的知觉水平上发生。通过操纵刺激的空间连续性，我们还评估了这种启动是否需要创建知觉上统一的表示。最后，我们研究了这种启动在衰老中的状态。在实验 1 中，我们发现，尽管空间连续性确实增强了联想启动的程度，但刺激的空间连续性对于新颖的图像联想启动的出现并不是必需的。在实验 2 中，我们发现，无论空间连续性如何，新的联想启动都是与年龄无关的。在实验 3 中，我们提供了额外的证据表明，图像联想启动是基于知觉的。这些发现扩展了新颖联想启动的范围和条件，并为关于新联想的内隐记忆本质的理论提供了信息。
