Metaphor and metonymy in ASD children: A critical review from a developmental perspective / Sergio MELOGNO in Research in Autism Spectrum Disorders, 6-4 (October-December 2012)
[article]
Titre : Metaphor and metonymy in ASD children: A critical review from a developmental perspective Type de document : Texte imprimé et/ou numérique Auteurs : Sergio MELOGNO, Auteur ; Maria Antonietta PINTO, Auteur ; Gabriel LEVI, Auteur Année de publication : 2012 Article en page(s) : p.1289-1296 Langues : Anglais (eng) Mots-clés : Metaphor Metonymy ASD children Development Review Index. décimale : PER Périodiques Résumé : The aim of the present article is to critically review the experimental research in the domain of metaphor and metonymy competencies in Autism Spectrum Disorders (ASD) children. After providing some basic definitions of metaphor and metonymy, we consider some major points emerging from studies on metaphorical and metonymical competencies in typical child development. Then, we review a number of emblematic studies concerning the relationship between autism and metaphor and metonymy, starting from the pioneering clinical studies by Kanner and Asperger in the 1940s. We also critically analyze experimental research on these same topics starting from the 1990s. The discussion highlights some major points emerging from recent experimental research and outlines possible perspectives for future research.

Titre : Is food refusal in autistic children related to TAS2R38 genotype? Type de document : Texte imprimé et/ou numérique Auteurs : M. P. RICCIO, Auteur ; C. FRANCO, Auteur ; R. NEGRI, Auteur ; R. I. FERRENTINO, Auteur ; R. MARESCA, Auteur ; E. D'ALTERIO, Auteur ; L. GRECO, Auteur ; Carmela BRAVACCIO, Auteur Article en page(s) : p.531-538 Langues : Anglais (eng) Mots-clés : ASD children PROP phenotype TAS2R38 genotype food selectivity Index. décimale : PER Périodiques Résumé : Several studies suggest that atypical eating behaviors, in particular food selectivity, are more frequent in children with autism spectrum disorder (ASD). A link between bitter taste perception, namely PROP/PTC sensitivity and food preferences is known in healthy children. The aim of this study is to investigate whether genetic variants of the TAS2R38 taste receptor responsible for different bitter sensitivity could affect foods preferences and consequently food refusal in ASD children. We recruited 43 children with ASD and 41 with normotypic development (TD) with or without food selectivity, aged between 2 and 11 years. Children were characterized for bitter sensitivity by means of PROP strips and FACS analysis and genotyped for TAS2R38 polymorphisms. Food selectivity was assessed by a validated food preference questionnaire filled by parents. A statistically significant correlation between PROP sensitivity and food refusal was observed. Furthermore, a prevalence of the PAV-sensitive haplotype compared to the AVI-insensitive one was seen in ASD children with food selectivity. In agreement with the initial hypothesis the results show that food refusal in ASD children is mediated by bitter taste sensitivity thus suggesting that the bitter sensitivity test may be used as a device to orientate tailored food proposals for the practical management of food selectivity in ASD. Autism Res 2018, 11: 531-538. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: A variation of the gene TAS2R38, associated with bitter taste sensitivity, can cause a different perception of some foods. In particular, some children are hypersensitive to bitterness and show a more restricted repertoire of accepted foods. We evaluate bitter sensitivity in ASD children with or without food selectivity, through a simple bitter taste test with edible strips. The results show that food refusal in ASD children can be mediated by bitter taste sensitivity thus suggesting that the bitter sensitivity test may be used as a device to orientate tailored food proposals for the practical management of food selectivity in ASD.
