Morphology
The meaning is directly derivable from the constituents: 'unconditioned' specifies that something is not learned/occurs automatically and 'reflex' is an automatic bodily response, so together they mean an automatic response without prior conditioning. This adjective+noun composition is compositional and cross-linguistically common, so a B1 learner who knows both words will comprehend it.
Etymology
Unconditioned reflex combines unconditioned (meaning 'not trained') and reflex (an 'automatic' action). It names responses like a baby's sucking or the knee-jerk that happen on their own, so it means a reaction that occurs without any prior learning.
