Troy and allan are in the mood to have a hamburger for lunch. troy wants to grill the hamburger outside instead of cooking it on top of the stove because he says he likes the taste of a grilled hamburger more than one cooked on top of the stove. the difference in taste troy prefers is actually caused by the smell of the charcoal embedded into the hamburger. this is an example of:

It is an example of sensory interaction.

Explanation:

The human body has 5 different senses, vision, hearing, smell, taste and touch. They often work altogether to give us a wide variety of sensations, even memories.

Taking the example provided above, Troy is mainly using the senses of smell and taste which commonly work together, 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.
