Early bilingual development: one language or two?

It is commonly thought that children learning two languages simultaneously during infancy go through a stage when they cannot differentiate their two languages. Virtually all studies of infant bilingual development have found that bilingual children mix elements from their two languages. These results have been interpreted as evidence for a unitary, undifferentiated language system (the unitary language system hypothesis). The empirical basis for these claims is re-examined and it is argued that, contrary to most extant interpretations, bilingual children develop differentiated language systems from the beginning and are able to use their developing languages in contextually sensitive ways. A call for more serious attention to the possible role of parental input in the form of mixed utterances is made.

Lateral eye movements during verbal and nonverbal dichotic listening.

A dichotic listening paradigm was used to study the relation of eye movement to cerebral lateralization. The eye movements of right-handed subjects were recorded during verbal and nonverbal dichotic-listening tasks. Subjects given a verbal dichotic-listening task made significantly more rightward than leftward eye movements and showed more accuracy and speed in processing information presented to the right than to the left ear. Subjects given a nonverbal dichotic-listening task made significantly more leftward eye movements and processed better information presented to the left ear. These findings suggest a potentially strong link between the direction of lateral eye movement during dichotic listening tasks and left- and right-ear advantages in performance on such tasks. They also suggest that both eye movement and ear performance may be related to cerebral laterality and when examined in combination both could provide valuable information for the further study of hemispheric specialization.
