视觉搜索中风味引发对关联颜色的注意偏向

人们常将特定的颜色与风味联系起来形成色味联结, 而且颜色线索会影响风味感知, 这体现了视觉信息对味觉信息加工的跨通道影响。本研究通过两个行为实验, 考察了味觉信息是否也会影响视觉搜索。实验任务要求被试品尝饮品后对形状靶子进行视觉搜索, 并且操纵了味觉刺激的提示性以及靶子颜色与风味之间的关联性。实验1的结果表明, 当风味线索提示的靶子颜色是与风味关联的颜色时可以加快视觉搜索。但如果与该风味关联的颜色出现在干扰项上, 风味线索则无法促进视觉搜索。其后, 我们在实验2中排除了语义启动的混淆, 也发现了与实验1一致的结果。本研究的结果表明, 风味线索会引发对关联颜色的注意偏向, 证实了味觉刺激对视觉注意的跨通道影响, 为色味交互提供了新的实验证据, 揭示了跨通道影响可能的发生机制。

Flavors bias attention toward associated colors in visual search

People tend to associate colors with specific flavors, establishing color-flavor associations, and people can generate flavor expectations about foods and beverages based on color. Recent research has shown that participants can generate color expectations about packaged food based on a flavor label to guide the visual search for this flavor. However, it remains unclear how flavors modulate color processing. Here, we conducted two visual search experiments to address this issue.
