This paper investigates the relationships between the times and the periods of infant word acquisition and word length. We divided an infant's word acquisition process into two subprocesses: comprehension and comprehension to production. Then we calculated the comprehension times and the periods from comprehension to production. For the word lengths, we used the lengths of entry words or utterances. Our experimental results showed weak correlation between the periods from comprehension to production and utterance lengths. In addition, we found a middle correlation of predicates consisting of verbs and adjectives.

Recent advancements in histological, anatomical, and neuroimaging studies of the infant brain in the perinatal and postnatal periods help us tackle the critical question of how infants acquire their native language. In this review, I will focus on the course of brain development and its relation to speech perception during the first year of life. The maturation of the temporal cortex, including the auditory areas as well as long-distance fibers, which connect the fronto-temporal regions, underlie the acquisition of spoken language. Multi-channel near-infrared spectroscopy can shed light on the initial formation of language networks in the developing brain.

Studies on language acquisition in infants have recently used brain imaging methods, such as NIRS (near infrared spectroscopy) and EEG (electroencephalography) measurements, as well as classical behavioral methods. These studies have demonstrated developmental changes in neural and behavioral responses during speech processing. In this article, I review some studies on Japanese infants and address development of behavioral and brain responses to Japanese lexical pitch accent and phonemic vowel length underlying the change in speech perception abilities.

The present study tracked 6-13 month-old Japanese infants' eye gaze when they observed either their mother or a stranger reciting a monologue. The purpose of this study is to examine the impact of age and face type (mother and stranger) on 1) how visual and auditory cues are employed and 2) which face parts (eye, nose and mouth) infants attend to. Our results revealed that infants started to prefer mother's voice regardless of the face type at 12 months-old and at the same time, they shifted their attention from the eyes to the mouth regardless of the face type. This shift appears about 4 months later as compared with that reported for English learning infants, suggesting that the developmental change for use of visual and auditory cues varies according to language/cultural environment.
