Infant faces elicit caregiving in adults. In previous research on brain responses to images of infant faces, the faces were unknown to participants. This study investigated EEG in primiparous mothers of 3- to 6-month-old infants viewing their own infant's face compared to an unfamiliar but appearance-matched infant's face. Spectral power was calculated and compared, and power at three EEG bands (delta, theta, and gamma) was found to differ between faces. Brain responses among primiparous mothers distinguish images of their own versus unfamiliar infants.
婴儿的面孔会引发成年人的照料行为。在先前关于大脑对婴儿面孔图像反应的研究中,参与者对这些面孔并不熟悉。本研究调查了初产妇母亲在观看自己3至6个月大婴儿的面孔与一个外貌匹配但不熟悉的婴儿面孔时的脑电图。计算并比较了频谱功率,发现三个脑电图频段(δ波、θ波和γ波)的功率在不同面孔之间存在差异。初产妇母亲的大脑反应能够区分自己婴儿与不熟悉婴儿的图像。
