Previous assessments of verbal cross-modal priming have typically been conducted with the visual and auditory modalities. Within-modal priming is always found to be substantially larger than cross-modal priming, a finding that could reflect modality modularity, or alternatively, differences between the coding of visual and auditory verbal information (i.e., geometric vs. phonological). The present experiments assessed implicit and explicit memory within and between vision and haptics, where verbal information could be coded in geometric terms. Because haptic perception of words is sequential or letter-by-letter, experiments were also conducted to isolate the effects of simultaneous versus sequential processing from the manipulation of modality. Together, the results reveal no effects of modality change on implicit or explicit tests. The authors discuss representational similarities between vision and haptics as well as image mediation as possible explanations for the results.
以往对言语跨通道启动效应的评估通常是在视觉和听觉通道中进行的。人们总是发现同通道启动效应远大于跨通道启动效应，这一发现可能反映了通道模块性，或者视觉和听觉言语信息编码之间的差异（即几何编码与语音编码）。本实验评估了视觉与触觉通道内及通道间的内隐记忆和外显记忆，其中言语信息可以用几何术语进行编码。由于对单词的触觉感知是按顺序或逐个字母进行的，因此还进行了实验，以从通道操作中分离出同时处理与顺序处理的效果。综合来看，结果显示通道变化对内隐或外显测试均无影响。作者讨论了视觉与触觉之间的表征相似性以及图像中介作用，将其作为对结果的可能解释。
