Research in first language development draws disproportionately from nontone languages. Such research is often presumed to reveal developmental universals in spite of the fact that most languages are tone languages. Recent research in the acquisition of tone languages points to a distinct course of development as compared to nontone languages. Our purpose is to provide an integrated review of research on lexical tone acquisition. First, the linguistic properties and origins of tone languages are described. Following this, research on the acquisition of tones in perception and production is reviewed and integrated. Possible reasons for the uniqueness of tone in language acquisition are discussed. Finally, theoretical advances promised by further research on tone acquisition and specific research directions are proposed.

Purpose: Children develop social-pragmatic understanding with the help of sensory, cognitive, and linguistic functions by interacting with other people. This study aimed to explore (a) associations between auditory, demographic, cognitive, and linguistic factors and social-pragmatic understanding in children who use bilateral hearing aids (BiHAs) or bilateral cochlear implants (BiCIs) and in typically hearing (TH) children and (b) the effect of the group (BiHA, BiCI, TH) on social-pragmatic understanding when the effects of demographic, cognitive, and linguistic factors are controlled for.
Method: The Pragma test was used to assess social-pragmatic understanding in 119 six-year-old children: 25 children who use BiHAs, 29 who use BiCIs, and 65 TH children.

Background/objectives: In a tonal language like Chinese, phonologically contrasting tones signify word meanings at the syllable level. Although the development of lexical tone perception ability has been examined in many behavioral studies, its developmental trajectory from childhood to adulthood at the neural level remains unclear. This cross-sectional study aimed to examine the issue by measuring the mismatch negativity (MMN) response to a Chinese lexical tonal contrast in three groups.

Speech is a highly skilled motor activity that shares a core problem with other motor skills: how to reduce the massive degrees of freedom (DOF) to the extent that the central nervous control and learning of complex motor movements become possible. It is hypothesized in this paper that a key solution to the DOF problem is to eliminate most of the temporal degrees of freedom by synchronizing concurrent movements, and that this is performed in speech through the syllable-a mechanism that synchronizes consonantal, vocalic, and laryngeal gestures. Under this hypothesis, syllable articulation is enabled by three basic mechanisms: target approximation, edge-synchronization, and tactile anchoring.

Tonal short-term memory has been positively associated with both incidentally acquired absolute pitch memory (e.g., for popular songs) and explicitly learned absolute pitch (AP) categories; however, the relationship between these constructs has not been directly tested within the same individuals.

Background And Objective: One of the functions attributed to the auditory efferent system is related to the processing of acoustic stimuli in noise backgrounds. However, clinical implications and the neurophysiological mechanisms of this system are not yet understood, especially on higher regions of the central nervous system. Only a few researchers studied the effects of noise on cortical auditory evoked potentials (CAEP), but the lack of studies in this area and the contradictory results, especially in children, point to the need to investigate different protocols and parameters that could allow the study of top-down activity in humans.
