Five-month-old infants characterized as low or high on temperamental negativity participated with their mothers in the still-face paradigm. Compared to low negative infants, high negative infants displayed greater negative engagement during reunion suggesting that infant temperament significantly contributes to individual differences in the still-face effect.
五个月大的婴儿被分为情绪消极程度低或高的两组,他们与母亲一起参与了面无表情范式实验。与情绪消极程度低的婴儿相比,情绪消极程度高的婴儿在重聚时表现出更大的消极反应,这表明婴儿的气质显著影响了面无表情效应的个体差异。
