- •
We recorded electrical brain and behavioral responses in adult humans.
- •
We induced small or large changes in small repetitive numerosities of tones.
- •
Only the large changes altered brain responses in inattentive subjects.
- •
Only 10.8% of the large changes were attentively detectable.
- •
Small numerosities were represented preattentively.
