What is 'cross-sensory bias' in sensory evaluation?

Cross-sensory bias refers to the phenomenon where the perception of one sensory modality, like taste or smell, is influenced by another modality. This interaction can significantly shape our overall sensory experience. For instance, the way we perceive flavor can be altered by the aromas we detect; a pleasant smell can enhance our taste experience, while an unpleasant smell can detract from it. This concept is crucial in sensory evaluation as it underscores the complexity of how our senses work together to create our perception of food and beverages. Recognizing cross-sensory bias is essential for sensory professionals in developing products and understanding consumer preferences, as it highlights that sensory evaluation cannot be isolated to individual sensory modalities but must consider their interconnectivity.
