The study adopts a multimodal perspective, looking at adults' use of gestures in variation sets (VS; i.e. sequences of partial self-repetitions occurring in successive utterances of varying form) addressed to Spanish-learning toddlers in adult-child interactions. We seek to address the following question: Do adults make simultaneous use of VS and…

Auditory brainstem implantation (ABI) is a recent innovation in pediatric hearing restoration in children with a sensorineural hearing impairment. Only limited information is available on the spontaneous speech development of severe-to-profound congenitally hearing-impaired children who received an ABI. The purpose of this study was to investigate…

The present study aimed to investigate the communicative characteristics of children with cochlear implants (CIs) and their mothers in interaction, whether and how they differ from those of mother-child dyads with normal hearing, and whether mother and child influence each other over the first year after implantation. Eighteen Italian-speaking…

This work presents an analysis of the intonation competence in a group of Italian children with cochlear implant (CI). Early cochlear implantation plays a crucial role in language development for children who were born deaf in that it favours the acquisition of complex aspects of language, such as the intonation structure. A story-generation task,…

This study deals with speech acts addressed to Hadza infants in Tanzania, a group that has traditionally lived off hunting and gathering. Three research questions are addressed: How do Hadza speech acts compare with those found in previous studies in other cultures? Are there differences between child and adult speakers? And do speech acts differ…

Children are known to use different types of referential gestures (e.g., deictic, iconic) from a very young age. In contrast, their use of non-referential gestures is not well established. This study investigated the use of "stroke-defined non-referential" 'beat' gestures in a story-retelling and an exposition task by twelve 6-year-olds,…

This study investigates prosodic modulation in the spontaneous canonical babble of congenitally deaf infants with cochlear implants (CI) and normally hearing (NH) infants. Research has shown that the acoustic cues to prominence are less modulated in CI babble. However acoustic measurements of individual cues to prominence give incomplete…

Recent research suggests that caregiver-child extratextual talk during shared book reading facilitates the development of preschool children's oral language skills. This study investigated the effects of the amount of picturebook text on mother-child extratextual talk during shared book reading. Twenty-four mother-child dyads (children aged…

Verbal working memory resources may impact syntax comprehension. Thirteen Italian children with cochlear implants (CIs) were assessed in relative clause (RC) comprehension, digit span and nonword repetition and compared to 13 chronological age peers (CA) and 13 younger controls (LA) with normal hearing (NH). The RC comprehension task tested…

This study explores the use of F0, intensity and duration in the production of two types of prominences in French: primary accent with duration as the main acoustic cue, and secondary accent with F0 and intensity as acoustic cues. These parameters were studied in 13 children using a cochlear implant (CI) and 17 children with a normal hearing (NH),…

This article investigates the amount of input and the quality of mother-child interactions in mothers who differ in socio-economic status (SES): mid-to-high SES (mhSES) and low SES. The amount of input was measured as the number of utterances per hour, the total duration of speech per hour and the number of turns per hour. The quality of the…

In early word productions, the same types of errors are manifest in children with cochlear implants (CI) as in their normally hearing (NH) peers with respect to consonant clusters. However, the incidence of those types and their longitudinal development have not been examined or quantified in the literature thus far. Furthermore, studies on the…

Weak performance in short-term memory (STM) in children with cochlear implants (CI) may have an impact on vocabulary development. Vocabulary, phonological STM (non-word repetition), phonological/verbal STM (digit span) and rapid naming measures were administered to 15 Greek-speaking children with CI (ages 4;6-8;6) and to chronological age (CA) and…

Many ancestral languages (AL) are at imminent risk of extinction due to societal changes that pressure minority communities to assimilate with dominant cultures and forego usage of their AL. This study aimed to encourage caregiver-child dyads to converse in Lazuri, an endangered AL in Rize, Turkey. Dyads (N = 59; child age M = 30.7 months, range…

This study examined lexical-phonological interactions in the first 50 words of a group of monolingual German- and Spanish-speaking children and bilingual German--Spanish children. The phonological characteristics of the earliest target word forms and output patterns of these children were analyzed to determine whether bilingual children select…
