Setting Event

A setting event doesn't directly trigger a behaviour - it changes the context so that a behaviour becomes much more or less likely than usual. Poor sleep the night before is a classic setting event. It doesn't cause a tantrum during math class, but it means the mild frustration of a difficult worksheet is now enough to tip the learner over.

Setting events matter because they explain the days when your usually-effective strategies fail. If a learner who normally tolerates transitions starts melting down despite your consistent approach, something in the background has shifted. Hunger, illness, a conflict at home, a disrupted routine - these are all setting events worth tracking.

Including setting events in your data collection (even as a simple notes column) helps you distinguish between intervention failure and contextual interference. The two require very different responses.
