Three-month-old infants of depressed (n=16) and non-depressed mothers (n=16) were habituated to video clips of a female model reciting phrases while posing happy or sad facial/vocal expressions and dishabituated to the alternate expressions. Overall, infants of depressed mothers took longer to habituate the video clips compared to infants of non-depressed mothers, and those assigned to habituate the sad video clips displayed a novelty response or dishabituated to the happy expressions. These findings suggest that 3-month-old infants of depressed mothers discriminate sad from happy expressions, however, they do not appear to perceive sad expressions as novel.
对16名抑郁母亲和16名非抑郁母亲的三个月大婴儿进行实验，让他们观看一名女性模特背诵短语的视频片段，模特同时做出开心或悲伤的面部/声音表情，之后再让他们观看相反表情的视频片段以检验他们是否习惯。总体而言，与非抑郁母亲的婴儿相比，抑郁母亲的婴儿观看视频片段达到习惯化的时间更长，那些被安排观看悲伤视频片段的婴儿对开心表情表现出新奇反应或不再习惯。这些发现表明，抑郁母亲的三个月大婴儿能够区分悲伤和开心表情，然而，他们似乎并不将悲伤表情视为新奇的。
