The unconditioned reflex are the reflexes that are part of the basic bodily functions which are not dependent on individuals past experiences with a particular type of stimulus.

These reflexes work by individuals learning to associated the stimulus with something else. For example, a dog may begin to salivate with smell of food because the dog has learnt to associate the smell with the food.
