While research acknowledges that the speech perception abilities of aging adults can be diminished in lower-level speech identification or discrimination, there is less concern about how aging affects higher-level speech understanding, particularly in tonal languages.

This study extends the previous investigation by testing the derivation of scalar (including both number and quantifier) and ad-hoc implicatures of a younger group of Mandarin-speaking autistic 4–8-year-olds; moreover, we assess the biological, linguistic, and cognitive factors affecting children's implicature acquisition.</p></div><div><h3>Methods</h3><p>The participants included 22 4–8-year-old autistic verbal children (mean age = 67.64 months) and 19 typically developing (TD) children who did not significantly differ in age, receptive vocabulary, and non-verbal IQ. Both groups completed a computer-based Truth Value Judgment task, assessing their knowledge of scalar (involving the number ‘three’ and the quantifier ‘some’) and ad-hoc implicatures.
