ABSTRACT Data from 492 Italian infants (8-18 months) were collected with the parental questionnaire MacArthur Bates Communicative Development Inventories to describe early actions and gestures (A-G) "vocabulary" and its relation with spoken vocabulary in both comprehension and production. A-G were more strongly correlated with word comprehension than word production. A clear developmental pattern for the different types of A-G was found. These findings are similar to those of different Western languages, indicating a common biological and cultural basis. The analysis of individual A-G and their relations with early words with a related meaning showed interesting similarities between the production of A-G with and without object manipulation and the comprehension and production of corresponding words. Results indicate that the transition from A-G to spoken language is mediated by word comprehension.

    • "Observational studies of typically developing (TD) children between 1;0 and 1;4 indicate that they primarily convey meanings by deictic (e.g., pointing) and representational gestures (e.g., gestures that replicate action schemes that are usually observed or performed by children with objects, such as bringing a fist to the ear to communicate the word TELEPHONE or the phrase TO PHONE) and by combining gestures and spoken production. As the age gradually increases to 1;8, the spoken modality increases in terms of types and tokens and becomes dominant with respect to the gestural modality (Capirci & Volterra, 2008; Caselli et al., 2012; Sansavini, Bello, et al., 2010). Bimodal spoken-gesture combinations continue to be employed to convey information, as indicated by observational and experimental studies (Capirci, Iverson, Pizzuto, & Volterra, 1996; Longobardi, Rossi-Arnaud, & Spataro, 2012; Stefanini, Bello, Iverson, Caselli & Volterra, 2009).

    ABSTRACT: Learning outcomes: After reading this manuscript, the reader will understand (a) the differences in noun and predicate comprehension and production between ELGA and FT children and the indexes of lexical delays exhibited by ELGA children at 2;0 (CCA); (b) the relevance of evaluating errors (incorrect response and no response), the types of incorrect responses (semantically related and unrelated) and the modality of the responses (unimodal spoken and bimodal spoken-gestural) in noun and predicate production to understand the difficulties experienced by ELGA children in representing and expressing meanings; and (c) the need to plan specific interventions to support spoken and gestural modalities in lexical comprehension and production in ELGA children by focusing on noun and predicate acquisition.

    ABSTRACT: Is displacement possible without language? This question was addressed in a recent work by Liszkowski and colleagues (Liszkowski, Schafer, Carpenter, & Tomasello, 2009). The authors carried out an experiment to demonstrate that 12-month-old prelinguistic infants can communicate about absent entities by using pointing gestures, while chimpanzees cannot. The main hypothesis of their study is that displacement does not depend on language but is, however, exclusively human and instead depends on species-specific social-cognitive human skills. Against this hypothesis, we will argue that a symbolic representation is needed to intentionally communicate absence and that this symbolic representation is tied to language. Moreover, data on the expression of displacement in home-sign systems will be taken into consideration. In light of this data, and in opposition to Liszkowski et al.'s (2009) claim, this paper will argue that displacement gestures are not foundational to language. Instead, they predate and predict the expression of complex forms of negation because they are specifically foundational to them.

    • "The Picture Naming Game (PiNG) (Bello, Giannantoni, Pettenati, Stefanini & Caselli, 2012) is a test for the assessment of lexical comprehension and production in preschool children. PiNG consists of four subtests: Noun Comprehension (NC), Noun Production (NP), Predicate Comprehension (PC) and Predicate Production (PP), each of which consists of 20 lexical targets and two training items.

    ABSTRACT: To address the negative effects of deafness on spoken language acquisition, many clinicians suggest using cochlear implant (CI) and oral education and advise against sign language, even when combined with spoken language (i.e., bilingualism), believing that it may slow down spoken language development. In a deaf child with CI who was exposed at an early age to Italian Sign Language and spoken Italian, we evaluated language development and the relationship between the two languages. The number of words/signs produced by the child consistently increased with age, and the vocabulary growth rate in spoken Italian was equivalent to that of hearing peers. Before CI, the child relied almost exclusively on sign language; after CI, he gradually shifted to spoken Italian yet still used sign language when unable to retrieve words in spoken Italian. We conclude that bimodal bilingualism may scaffold the development of spoken language also in deaf children with CI.
