Research has shown that information accessed from one sensory modality can influence perceptual and attentional processes in another modality. Here, we demonstrated a novel crossmodal influence of haptic-shape information on visual attention. Participants visually searched for a target object (e.g., an orange) presented among distractor objects, fixating the target as quickly as possible. While searching for the target, participants held (never viewed and out of sight) an item of a specific shape in their hands. In two experiments, we demonstrated that the time for the eyes to reach a target-a measure of overt visual attention-was reduced when the shape of the held item (e.g., a sphere) was consistent with the shape of the visual target (e.g., an orange), relative to when the held shape was unrelated to the target (e.g., a hockey puck) or when no shape was held. This haptic-to-visual facilitation occurred despite the fact that the held shapes were not predictive of the visual targets' shapes, suggesting that the crossmodal influence occurred automatically, reflecting shape-specific haptic guidance of overt visual attention.
研究表明，从一种感官模态获取的信息可以影响另一种模态中的感知和注意过程。在此，我们展示了触觉形状信息对视觉注意力的一种新型跨模态影响。参与者在分心物体中视觉搜索呈现的目标物体（例如一个橙子），并尽快注视目标。在搜索目标时，参与者手中拿着（从未看过且看不见）一个特定形状的物品。在两项实验中，我们证明，相对于手中拿着的形状与目标无关（例如一个曲棍球）或未拿任何形状物品时，当手中拿着的物品形状（例如一个球体）与视觉目标（例如一个橙子）的形状一致时，眼睛看向目标的时间（一种显性视觉注意力的测量指标）会缩短。尽管手中拿着的形状并不能预测视觉目标的形状，但这种触觉到视觉的促进作用依然出现了，这表明跨模态影响是自动发生的，反映了显性视觉注意力的形状特异性触觉引导。
