Abstract

Habituation and dishabituation are the most prevalent measures of infant cognitive functioning, and they have reliably been shown to predict later cognitive outcomes. Yet, the exact mechanisms underlying infant habituation and dishabituation are still unclear. To investigate them, we tested 106 8-month-old infants on a classic habituation task and a novel visual learning task. We used a hierarchical Bayesian model to identify individual differences in sustained attention, learning performance, processing speed and curiosity from the visual learning task. These factors were then related to habituation and dishabituation. We found that habituation time was related to individual differences in processing speed, while dishabituation was related to curiosity, but only for infants who did not habituate. These results offer novel insights in the mechanisms underlying habituation and serve as proof of concept for hierarchical models as an effective tool to measure individual differences in infant cognitive functioning.

Research Highlights

We used a hierarchical Bayesian model to measure individual differences in infants’ processing speed, learning performance, sustained attention, and curiosity.
Faster processing speed was related to shorter habituation time.
High curiosity was related to stronger dishabituation responses, but only for infants who did not habituate.

处理速度和好奇心的个体差异解释了婴儿的习惯化和非习惯化表现。

习惯化和非习惯化是婴儿认知功能最普遍的测量方法，它们已被可靠地证明可预测日后的认知结果。然而，婴儿习惯化和非习惯化的确切机制仍不清楚。为了研究这些机制，我们对 106 名 8 个月大的婴儿进行了经典的习惯化任务和新颖的视觉学习任务测试。我们使用分层贝叶斯模型从视觉学习任务中找出了持续注意力、学习成绩、处理速度和好奇心的个体差异。然后将这些因素与习惯化和非习惯化联系起来。我们发现，习惯化时间与处理速度的个体差异有关，而非习惯化与好奇心有关，但只针对没有习惯化的婴儿。这些结果为研究习惯化的内在机制提供了新的视角，并证明了分层模型是测量婴儿认知功能个体差异的有效工具。研究亮点：我们使用分层贝叶斯模型来测量婴儿处理速度、学习成绩、持续注意力和好奇心的个体差异。处理速度快与习惯化时间短有关。高好奇心与较强的去习惯化反应有关，但只针对没有习惯化的婴儿。
