Efficient visual exploration in infancy is essential for cognitive and language development. It allows infants to participate in social interactions by attending to faces and learning about objects of interest. Visual scanning of scenes depends on a number of factors, and early differences in efficiency are likely contributing to differences in…

Relations between maternal responses and infants' communication skills at 12 and 24…

As expected, older children had on average larger vocabularies compared to younger children.…

The aim was to identify possible markers of early language delay. The authors monitored vocabulary…
