A neutral cue can acquire emotional meaning
A sound that once meant little can gain significance after being paired with a meaningful event. A particular notification tone may begin to create anticipation if it repeatedly precedes welcome messages. Classical conditioning describes learning a relationship between stimuli, rather than learning through a reward for an action.

Experience changes what a cue predicts
A notification tone starts as an ordinary sound. After repeatedly accompanying messages someone enjoys, the tone itself may begin to produce anticipation before the message is read.
In classical conditioning, a cue acquires the ability to evoke a response through its relationship with another stimulus. The learned response is not necessarily identical to the response to the original event.
The relationship matters more than mere repetition. A tone that predicts many unrelated outcomes may develop a different meaning from one that reliably signals a particular event.
This learning process helps explain why places, sounds or smells can acquire emotional significance. The cue is linked to experience, rather than carrying the same meaning for everyone who encounters it.
