Unconditioned

In the context of learning or behavior, 'unconditioned' describes a response, stimulus, or reflex that occurs naturally and without prior learning or training. It's an inherent or innate reaction, not reliant on past experiences or associations. The term highlights an action that's triggered by a specific stimulus due to biological wiring, as opposed to something that's learned or acquired over time. It's a foundational element in understanding how both humans and animals respond to their environments. Think of it as a raw, unfiltered reaction.
