概括

两岁半的婴儿可以敏感地识别其他种族的面孔. 亚洲面部双模分布的训练提高了他们的歧视能力,显示了面部感知可塑性.

科学领域:

发展心理学发展心理学
认知神经科学认知神经科学
感知学习学习是感知学习.

背景情况:

婴儿通常会经历感知狭窄,在第一年后对其他种族面孔的敏感性降低.
然而,婴儿可以通过统计学学习等方法恢复对其他种族的面部敏感性.
这项研究探讨的是,是否也可以使较大的幼儿 (2.5岁) 变得敏感.

研究的目的:

调查对2.5岁的高加索婴儿敏感化歧视其他种族 (亚洲) 面部的潜力.
为了确定暴露于特定的统计分布是否可以增强幼儿的其他种族面部感知.
为了评估幼儿时期面部感知可塑性.

主要方法:

训练2.5岁的婴儿,以亚洲形态化女性面部的双模分布.
在培训期间,更频繁地呈现更接近连续性终点的面孔.
通过测量婴儿观察时间来评估亚洲人面对的歧视.

主要成果:

2.5岁的婴儿在训练阶段后的观察时间有显著差异.
这表明,在接触双模分布后,亚洲人面部受到了成功的歧视.
这些发现表明,在幼儿中可以发生感知学习.

结论:

2.5岁的孩子可以有效地敏感地歧视其他种族的面孔.
接触双模频率分布可以增强幼儿对其他种族人脸的感知.
这突显了儿童发育期间面部感知显著的可塑性.
