10个月大的婴儿观看了一位女演员自发做出快乐或悲伤面部表情的录像带片段。记录左侧和右侧额叶和顶叶头皮区域的脑活动。在两项研究中，婴儿对快乐部分的反应表现出左侧额叶比右侧额叶区域更大的激活。顶骨不对称未能区分这两种情况。情感过程大脑半球的不同偏侧化似乎在10个月龄时就已确立。
Ten-month-old infants viewed videotape segments of an actress spontaneously generating a happy or sad facial expression. Brain activity was recorded from the left and right frontal and parietal scalp regions. In two studies, infants showed greater activation of the left frontal than of the right frontal area in response to the happy segments. Parietal asymmetry failed to discriminate between the conditions. Differential lateralization of the hemispheres for affective processes seems to be established by 10 months of age.
