Contamination can have undesirable consequences in real experiments, some of them are related to the feelings that may arise in the research participants, the contamination bias reduces the differences between the research groups, and can cause a comparison between the treatments of each different group, the which can generate conflicts and rivalries on the part of groups that consider themselves to be inferior to others. These contamination-related problems can significantly interfere with the research results.

Explanation:
The autonomic nervous system (ANS) is a control system that is responsible for controlling the body's unconscious functions (e.g., digestion, respiratory rate, heart rate, pupillary response, sexual arousal, etc). The ANS is divided into the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system comprises nerves from the thoracic and lumbar segments of the spinal cord (responsible for fight or flight); whereas the parasympathetic nervous system is composed primarily of the cranial and sacral spinal nerves (responsible for controlling many of the body's functions when it is at rest). Moreover, antagonistic innervation occurs when an organ is controlled by two different types of nerves, i.e., dual innervation of the organ by both divisions of the ANS, where the effects of the sympathetic and parasympathetic divisions are antagonistic (i.e., they oppose each other). On the other hand, there are situations where the dual innervation results in a unilateral cooperative response (for example, the urinary system is innervated by parasympathetic and sympathetic nerve fibers that exhibit cooperative effects).
