The aim of this study was to demonstrate that the cross-modal priming effect is perceptual and therefore consistent with the idea that knowledge is modality dependent. We used a two-way cross-modal priming paradigm in two experiments. These experiments were constructed on the basis of a two-phase priming paradigm. In the study phase of Experiment 1, participants had to categorize auditory primes as "animal" or "artifact". In the test phase, they had to perform the same categorization task with visual targets which corresponded either to the auditory primes presented in the study phase (old items) or to new stimuli (new items). To demonstrate the perceptual nature of the cross-modal priming effect, half of the auditory primes were presented with a visual mask (old-masked items). In the second experiment, the visual stimuli were used as primes and the auditory stimuli as targets, and half of the visual primes were presented with an auditory mask (a white noise). We hypothesized that if the cross-modal priming effect results from an activation of modality-specific representations, then the mask should interfere with the priming effect. In both experiments, the results corroborated our predictions. In addition, we observed a cross-modal priming effect from pictures to sounds in a long-term paradigm for the first time.
本研究的目的是证明跨模态启动效应是感知性的，因此与知识依赖于模态的观点一致。我们在两个实验中使用了双向跨模态启动范式。这些实验是在两阶段启动范式的基础上构建的。在实验1的研究阶段，参与者必须将听觉启动刺激归类为“动物”或“人工制品”。在测试阶段，他们必须对视觉目标执行相同的分类任务，这些视觉目标要么与研究阶段呈现的听觉启动刺激（旧项目）相对应，要么与新刺激（新项目）相对应。为了证明跨模态启动效应的感知性质，一半的听觉启动刺激与视觉掩蔽一起呈现（旧掩蔽项目）。在第二个实验中，视觉刺激用作启动刺激，听觉刺激用作目标，并且一半的视觉启动刺激与听觉掩蔽（白噪声）一起呈现。我们假设，如果跨模态启动效应是由特定模态表征的激活引起的，那么掩蔽应该会干扰启动效应。在两个实验中，结果都证实了我们的预测。此外，我们首次在长期范式中观察到了从图片到声音的跨模态启动效应。
