Poverty may trigger earlier puberty in girls, shaping later mental health and academics

A longitudinal study of nearly 10,000 children starting at age 9 found that household and neighborhood disadvantage predicted earlier pubertal onset in both sexes, but in girls this earlier puberty partly explained later anxiety, behavioral issues, and lower grades by age 12; boys showed earlier puberty without the same outcome link, and puberty tempo slowed later, complicating the association. The researchers note small effect sizes but potential population-level impact and call for earlier-starting research.

Trauma reshapes how children's brains read caregiver cues

A study of 148 children aged 4–9 found that exposure to threat (abuse, witnessing domestic violence) is linked to greater insula activation when processing a caregiver’s cue, suggesting trauma makes caregiver signals more salient and engages interoceptive processing. Deprivation showed no similar effect, indicating adversities affect brain circuitry in distinct ways. The study used a multimodal fMRI task comparing caregivers to strangers and highlighted cross-sectional limits and the need to explore attachment and long-term mental health outcomes.

"At What Age Do Babies Develop Consciousness?"

Researchers propose a new method to determine when consciousness emerges in infants by identifying markers of consciousness in adults and tracking their appearance in babies' development. This approach aims to address the challenge of studying consciousness in non-verbal subjects like infants and could provide insights into the complex process of becoming conscious. The study suggests that consciousness may emerge early, from the last prenatal trimester, and recommends considering a broad range of developmental markers to pinpoint the onset of consciousness.
