Preterm birth (<37 gestational weeks) is associated with long-term risks for health and neurodevelopment, but recently, studies have also started exploring how preterm birth affects early language development in the 1st year of life. Because the timing and quality of auditory and visual input is very different for preterm versus full-term…

Audiovisual speech consists of overlapping and invariant patterns of dynamic acoustic and optic articulatory information. Research has shown that infants can perceive a variety of basic auditory-visual (A-V) relations but no studies have investigated whether and when infants begin to perceive higher order A-V relations inherent in speech. Here, we…

Infant phonetic perception reorganizes in accordance with the native language by 10 months of age. One mechanism that may underlie this perceptual change is distributional learning, a statistical analysis of the distributional frequency of speech sounds. Previous distributional learning studies have tested infants of 6-8 months, an age at which…

Reviews pertinent developmental and neuropsychological literature and arrives at a hypothesis relating the left brain lateralization of speech to the origin of early naming as part of selective (right-biased) orienting to perceived salience or change. (Author/SS)
