Stimulus
Trigger
A stimulus is any input — external or internal — that prompts a human response. It is the starting point of experience: the raw event before it has been given any meaning.
Something happens. That's the stimulus. It hasn't meant anything yet — it's just the thing that occurred.
Duration
Instantaneous — a single moment or event
Origin
The world around you, your body, or your own thoughts
Purpose
To provide the raw material of experience. Without a stimulus there is nothing to interpret, and therefore nothing to feel.

A late reply
Your message is left on read for six hours. That is the stimulus. Whether it means rejection or a busy day is not part of the stimulus itself.
A raised voice
Someone speaks to you loudly. The raised voice is the stimulus — the interpretation of anger, urgency, or excitement comes next.
Common confusion
Everyday language
“That made me angry.”
More precisely
“That was the stimulus; my interpretation produced the anger.”
A stimulus cannot directly create an emotion. It must first pass through interpretation. The same stimulus can produce very different emotions in different people.
