Mounting evidence suggests that maternal stress is associated with infants' brain activity, but the role of maternal stress during pregnancy is not yet understood. The present preregistered investigation examines associations between prenatal maternal stress (physiological and perceived) and infant brain activity at 1 month of age. A sample of diverse mother-infant dyads (N = 160) participated (55% female; 39% White). Maternal physiological stress was not associated with infant EEG power. In contrast, higher maternal perceived stress was associated with decreased absolute theta power (β = -0.035, p = 0.042). Higher maternal perceived stress was also associated with decreased absolute (β = -0.016, p = 0.038) and relative (β = -0.047, p = 0.039) alpha power. These findings suggest that maternal perceived stress during pregnancy is associated with infant brain activity shortly after birth.
越来越多的证据表明，母亲的压力与婴儿的大脑活动有关，但孕期母亲压力的作用尚不清楚。本项预先注册的调查研究了产前母亲压力（生理压力和感知压力）与1个月大婴儿大脑活动之间的关联。一个多样化的母婴二元组样本（N = 160）参与了研究（55%为女性；39%为白人）。母亲的生理压力与婴儿脑电图功率无关。相比之下，母亲感知到的压力越大，绝对θ波功率越低（β = -0.035，p = 0.042）。母亲感知到的压力越大，绝对α波功率（β = -0.016，p = 0.038）和相对α波功率（β = -0.047，p = 0.039）也越低。这些发现表明，孕期母亲感知到的压力与婴儿出生后不久的大脑活动有关。
