Explain 'Cross-modal sensory interactions.'

Cross-modal sensory interactions refer to the phenomenon where one sensory modality influences the perception or experience of another modality. This means that our perception is not isolated to one sense; rather, it is a multi-sensory experience where, for example, what we see can affect what we taste, or what we hear can influence what we smell.

In the context of sensory evaluation, understanding these interactions is crucial as they help improve product development and consumer experiences. For instance, the sound of a crunchy food item may enhance the perception of its freshness, while the aroma of a beverage can influence the perceived taste. Recognizing how these modalities interact allows for a deeper comprehension of sensory experiences and can guide improvements in product formulation to create a more appealing overall experience for consumers.
