Negative Pragmatic Transfer in Bilinguals: Cross-Linguistic Influence in the Acquisition of Quantifiers.

Building on the cross-linguistic variability in the meaning of vague quantifiers, this study explores the potential for negative transfer in Italian-Slovenian bilinguals concerning the use of quantificational determiners, specifically the translational equivalents of the English "many", that is the Slovenian "precej" and "veliko". The aim is to identify relevant aspects of pragmatic knowledge for cross-linguistic influence. The study presents the results of a sentence-picture verification task in which Slovenian native speakers and Italian-Slovenian bilinguals evaluated sentences of the form "Quantifier X are Y" in relation to visual contexts. The results suggest that Italian learners of Slovenian, unlike Slovenian native speakers, fail to distinguish between "precej" and "veliko". This finding aligns with the negative transfer hypothesis. The study highlights the potential role of pragmatic knowledge in cross-linguistic transfer, particularly in the context of vague quantifiers.

Understanding indirect requests for information in high-functioning autism.

Few works have addressed the processing of indirect requests in High-Functioning Autism (HFA), and results are conflicting. Some studies report HFA individuals' difficulties in indirect requests comprehension; others suggest that it might be preserved in HFA. Furthermore, the role of Theory of Mind in understanding indirect requests is an open issue. The goal of this work is twofold: first, assessing whether comprehension of indirect requests for information is preserved in HFA; second, exploring whether mind-reading skills predict this ability. We tested a group of (n = 14; 9-12 years) HFA children and two groups of younger (n = 19; 5-6 years) and older (n = 28; 9-12 years) typically developing (TD) children in a semi-structured task involving direct, indirect and highly indirect requests for information. Results suggested that HFA can understand indirect and highly indirect requests, as well as TD children. Yet, while Theory of Mind skills seem to enhance older TD children understanding, this is not the case for HFA children. Therefore, interestingly, they could rely on different interpretative strategies.

Scalar and ad-hoc pragmatic inferences in children: guess which one is easier.

Several studies investigated preschoolers' ability to compute scalar and ad-hoc implicatures, but only one compared children's performance with both kinds of implicature with the same task, a picture selection task. In Experiment 1 (N = 58, age: 4;2-6;0), we first show that the truth value judgment task, traditionally employed to investigate children's pragmatic ability, prompts a rate of pragmatic responses comparable to the picture selection task. In Experiment 2 (N = 141, age: 3;8-9;2) we used the picture selection task to compare scalar and ad-hoc implicatures and linked the ability to derive these implicatures to some cognitive and linguistic measures. We found that four- and five-year-olds children performed better on ad-hoc than on scalar implicatures. Furthermore, we found that morphosyntactic competence was associated with success in both kinds of implicatures, while performance on mental state reasoning was positively associated with success on scalar but not ad-hoc implicatures.

Ad-hoc and scalar implicatures in children with autism spectrum disorder.

BACKGROUND: Previous studies found that people with Autism Spectrum Disorder (ASD) perform well on pragmatic inference tests that require the use of the linguistic scale . The present study extends previous research by testing two types of implicature: scalar implicatures, based on lexical scales, and ad-hoc implicatures, based on contextual scales. METHODS: We tested 26 children with ASD aged 4-10 years (mean age 7.1) and 26 typically developing (TD) children - matched on chronological age and with a similar performance in non-verbal IQ and vocabulary - by means of a picture selection task for scalar and ad-hoc implicatures. We also investigated the effect of children's scores in standardized tests measuring non-verbal intelligence, lexical, and morphosyntactic abilities and Theory-of-Mind skills on their performance in the implicature tasks. RESULTS: Although more than half of the children with ASD performed above chance on both kinds of implicatures, their performance as a group was significantly lower than the performance of their TD peers. General cognitive abilities were found to affect the performance of children with ASD on both kinds of implicatures, and Theory-of-Mind reasoning skills were found to be linked to their performance on scalar, but not ad-hoc implicatures. CONCLUSIONS: We show that children with ASD have difficulty with both kinds of implicatures. These findings may have implications for explanatory theories of pragmatics as well as for clinical work with children with ASD.

The Production of Pronouns and Verb Inflections by Italian Children with ASD: A New Dataset in a Null Subject Language.

The language of children with autism spectrum disorder (ASD) is often characterized by difficulties with pronouns. The underlying reasons for such difficulties are still unclear. This study is the first to test the abilities of children with ASD who speak Italian, a language in which overt subject pronouns are optional but verbs obligatorily feature person-referencing morphology. We found that Italian children with ASD were less accurate than typically-developing (TD) Italian children in the production of first-, second-, and third-person singular pronouns, avoiding pronouns in favor of nouns or names more often than controls. Moreover, children with ASD produced more overt pronouns than null pronouns in marked contexts, compared to TD children. These phenomena can be accounted for by difficulties with pragmatics.
