A relação entre o biológico e o cultural na aquisição da linguagem e a instauração da criança na interdependência entre forma-sentido na língua materna

Construct validation of enunciative signs of language acquisition for the first year of life

“…The variables identified as relevant in the factor analysis of the Phase 1 instrument for the infant element, i.e., the infants' reactions to motherese and the non-verbal expression of their demands, whether sound or silent, attuned to the enunciative context (items 1, 3, 4), were those showing that the infants have an appetite for protoconversation and, combined with the adults' investment (item 7), suggest absence of risk of language acquisition. This result reinforces the importance of initial protoconversation, supporting previous studies on at-risk populations (6,7,8) as well as on typical acquisition (9) .…”

“…This explains the relevance of the enunciative perspective for the study of language acquisition. Silva (9) proposes that the I-you relationship is essential for the analysis of language acquisition, which was clearly reflected in the results reported here due to the fact that factor analysis identified one factor describing the I-infant factor (Factor 1) and one factor describing the you-adult factor (Factor 2). This indicates that not only the infants' conditions but also the investment that adults make in the interlocution with them is essential in the language acquisition process, which confirms the initial hypothesis suggested by Crestani (10) : dialogue is an important unit of analysis in language acquisition because it enables observation of the enunciative scaffolding provided by adults to assist infants with building grammar knowledge and a place in speech.…”

“…This scenario, in addition to the emergence of enunciative studies on language acquisition (9) , led to the development of enunciative signs of language acquisition (ESLA), whose content and construct validity were reported by Crestani et al (10) , who presented the results of the judgment of six language acquisition experts on the pertinence of the proposed signs for two age groups (phase 1: 3-6 months; phase 2: 7-12 months) (Chart 1). The enunciative view of language acquisition assumes that adults engage infants in dialogue until the latter can take on their position as speakers (9) .…”

These signs aim to promote the early detection of any impairment in language acquisition based on an evidence-based paradigm (11) , which means that the absence of ESLA is indicative of the onset of a language symptom, whereas the presence of these signs is a positive finding, showing that language acquisition is occurring appropriately.…”

“…These signs aim to promote the early detection of any impairment in language acquisition based on an evidence-based paradigm (11) , which means that the absence of ESLA is indicative of the onset of a language symptom, whereas the presence of these signs is a positive finding, showing that language acquisition is occurring appropriately. The ESLA are based on the enunciative proposal (9) that attests that infants are supported in the functioning of language by adults until they can acquire knowledge of the language through initial protoconversations and interlocution. Infants will move from adult discursive dependency to independence from the moment they can establish a co-reference and settle in the discourse through double enunciation.…”
