The present project investigates the developmental trajectory of perceptual narrowing in speech and faces and its potential modification during infancy and early childhood. The research focuses on the hypothesis that perceptual narrowing is a first step in a process that leads to a stronger separation of information processing in these two domains. This hypothesis is tested by experimental studies targeting the interactions and modifications of speech and face processing, mainly in training experiments that try to reverse effects of perceptual narrowing in toddlers and preschool children. In addition, we will study the neural underpinnings that are associated with the narrowing process during the first year of life but also with the potential reversal of this process after training. The results will provide new insights into the contribution of domain-general or domain-specific mechanisms to early human development.

本研究旨在探讨言语和面孔知觉窄化的发展轨迹及其在婴儿期和幼儿期的潜在变化。该研究的重点是假设知觉收窄是一个过程中的第一步，导致在这两个领域的信息处理更强的分离。这一假设通过针对言语和面部处理的相互作用和修改的实验研究进行了验证，主要是在试图扭转幼儿和学龄前儿童知觉狭窄影响的训练实验中。此外，我们还将研究与生命第一年的缩窄过程相关的神经基础，以及训练后该过程的潜在逆转。这些结果将为领域一般或领域特异性机制对早期人类发展的贡献提供新的见解。
