Bridging the environment and neurodevelopment for children's health: Associations between real-time air pollutant exposures and cognitive outcomes.

The tests revealed a near-significant difference in three-day average PM 2.5 readings between Round 1 and Round 2 ( Z = −1.96; p = 0.05), and no differences in three cognitive measures: working memory ( Z = −1.13; p = 0.26), inhibitory control ( Z = −1.52; p = 0.10), and arithmetic ( Z = −0.87; p = 0.39).

However, there was a nearly statistically significant decrease in exposure (and a significant improvement in non-symbolic comparison ability) between the first and second round of data collection.
