The article reports that among twins, a higher relative birthweight is linked to slightly higher cognitive performance in childhood and adolescence, with the association strongest for birthweight differences rather than head circumference. The effect appears within twin pairs, suggesting womb-based conditions influence long-term cognition independent of shared genetics and environment.

This topic is of interest to psychology because it illuminates how early physiological development relates to later cognitive outcomes, highlighting the enduring impact of prenatal factors on brain development and the interplay between biology and environment.

Neuroscience Says People Who Fall Asleep Mid-Problem Are Actually Running a Memory Consolidation Process That Most People Interrupt

The article describes a study linking high consumption of ultra-processed foods in early childhood to lower IQ scores at ages six to seven. The negative association was stronger among children who showed growth delays in infancy, and persisted after accounting for socioeconomic status and home stimulation. Possible mechanisms include gut-brain interactions and oxidative stress, though the study is observational.

This topic is of interest to psychology because it highlights how early nutrition can shape cognitive development and later school performance, illustrating the interaction between biological vulnerability and environmental exposure. It also raises considerations about confounding and cumulative disadvantage in developmental research.
