Which description best defines Single Event Learning?

• A. A stimulus clearly causes a response.
• B. Learning that occurs when something happens that is not related to anything else.
• C. A response is reinforced only on a variable schedule.
• D. Learning that happens through punishment.

Answer: (A)

Single-event learning is about forming an association after one clear exposure, so a cue directly leads to a response. When a stimulus reliably elicits a behavior after a single encounter, that immediate cause-and-effect link reflects this one-shot learning. The description that a stimulus clearly causes a response captures that idea precisely—the connection doesn’t require multiple trials or reinforcement across sessions.

The other ideas describe different processes: learning from an event that isn’t linked to a cue, or learning shaped by reinforcing patterns over time (like variable reinforcement), or learning through punishment. These aren’t about forming a direct, single-trial cue–response link.
