Researchers scrutinize the long-held perception that new mothers are more forgetful and less attentive. Mothers, they found, have similar alerting and orienting attention, and better executive control attention compared to women without children.
Children who experience early life adversity experience faster biological aging than children with no history of exposure to abuse. Trauma was associated with biological aging in early puberty, cellular aging, and alterations in brain structure. The findings may explain why children who experienced adversity early in life often suffer poor health as they age.
Children who experienced higher levels of distress and less physical contact had a lower epigenetic age than those who were picked up and held more frequently, researchers report. Lower epigenetic age, researchers note, may impede a child's ability to thrive.
Those on the autism spectrum had atypically smaller pupil dilation compared to the control group during distracting conditions while taking a push-button test. The findings suggest those with ASD may have dysregulation in locus coeruleus activity. The dysregulation of the LC may explain the exaggerated responses to environmental stimuli and fixated behaviors many with ASD experience.
