Which term refers to the natural eliciting event that produces a reflex without learning?

• A. Unconditioned Stimulus
• B. Unconditioned Response
• C. Functional Analysis
• D. Extinction

Answer: (A)

The natural eliciting event that produces a reflex without learning is the unconditioned stimulus. The unconditioned stimulus is anything that naturally triggers an automatic response without any prior training or conditioning. For example, food presented to a hungry animal reliably causes salivation—the salivation is the unconditioned response. If a neutral signal is paired with that stimulus over time, the signal can come to elicit a response on its own (a conditioned response), but the original reflex itself is driven by the unconditioned stimulus. The other terms refer to different concepts: the unconditioned response is the reflex itself, extinction is the decrease of a learned response when reinforcement stops, and functional analysis is a method for understanding the purpose a behavior serves, not the reflex trigger.
