What is it about?
This study is about the relationship between prenatal substance exposure and infant visual recognition memory to later cognitive abilities. We assessed children, both of high and low biomedical risk, with an infant recognition test at 27 and 39 weeks, and again with the McCarthy Scales in middle childhood.

Why is it important?
Regression analyses showed that prenatal substance exposure and early recognition memory each independently predicted later cognitive performance.
Perspectives
Findings show that prenatal adversity notably impacts perceptual recognition abilities and suggest that infant recognition memory reliably reflects brain function. The study also underscores the need to consider the reliability of infancy measures when assessing their effects on later cognition.
