According to the gate-control theory of pain, which of the following would be an effective way to decrease the pain of banging your elbow?
A) jumping up and down
B) rubbing the area around it
C) screaming very loudly
D) thinking happy thoughts
Answer: B
Rationale: A long-held theory of pain perception is called gate-control theory, which explains our experience of pain as an interaction between nerves that transmit pain messages and those that inhibit these messages. Put simply, rubbing, touching, or tickling an area stimulates nerve fibers which "close" the pain gates, inhibiting the pain signal coming from the same area.
