This study investigates the role of perception and sensory motor learning on speech production in L2. Compared to natural language learning, acoustic input in formal adult instruction is deprived of multiple sensory motor cues and lacks the imitation component. Consequently, it is possible that inaccurate pronunciation results from training.…

Over half the world's population speaks a tone language, yet infant speech perception research has typically focused on consonants and vowels. Very young infants can discriminate a wide range of native and nonnative consonants and vowels, and then in a process of "perceptual reorganization" over the 1st year, discrimination of most…

The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…
