Lucarini, G., Colavolpe, B., Burgato, L., Gervain, J. (under review). The Development of Italian Vocabulary, Morphology and Syntax: an Observational Study.
In accordance with TalkBank rules, any use of data from this corpus must be accompanied by at least one of the above references.
The corpus was collected to investigate how combinatoriality emerges in early Italian language acquisition, both in morphology and syntax, and its link to vocabulary growth.
The corpus is composed by 30 transcriptions and audio-recordings of 7 children collected between 2021 and 2022. Children (6 males; 1 female) were recruited from a family daycare service in the North-East of Italy and their spontaneous productions were collected to evaluate the complexity and productivity of children’s early speech.
The children, according to parental reports, had no known neurological, auditory, or language-related pathologies, they were all Italian monolingual speakers with both parents being native Italian speakers. Data were collected in two phases: Phase 1 (01/06/2021 - 20/08/2021) and Phase 2 (03/01/2022 - 05/04/2022). At the beginning of data collection, the children were between 1;6-2;5 years of age (m=1;11.2, SD=0;3.7) and at the end of the study, the age range was 2;4-3;1 year (m=2;9, SD=0;3). One infant (CHI1) dropped out, while another one (CHI7) entered the study after Phase 1. To assess children's vocabulary, the Italian version of the MacArthur-Bates CDI (Caselli et al., 2015) was administered. The questionnaires were administered twice, once in Phase 1 and once in Phase 2. All children were within the normal range (>5th percentile) on the MacArthur-Bates CDI in both Phases 1 & 2.
