Explanation:

Taking the example provided above, <em>Troy is mainly using </em><em>the senses of smell and taste </em><em>which commonly work together</em>, e.g. when you smell freshly baked bread or cookies you can almost feel the flavor of it. Not only the senses of smell and taste work together but all the senses also combine each other in many different ways, for example, vision and taste when we see food on TV commercials, or hearing and vision when we watch movies.
That is sensory interaction, the influence/interaction of one sense over others.
