Recursion is a cognitive capacity, potentially unique to humans, which allows the generation of hierarchies with multiple levels of embedding. This capacity is thought to primarily underlie syntactic structures in language (Berwick & Chomsky, 2016), but is also available in other domains such as vision (Martins, 2012). An open question is whether a purportedly primary linguistic capacity is used in other domains, or whether visual recursion can develop in the absence of language. If the latter, is recursion a domain-general or multi-domain-specific? Here we further test the hypothesis that linguistic and visual recursion are independent, in the framework of a case study. Its subject is Álex (AX), a 12-yearold autistic child (ADI-r and ADOS assessed) with an oral open-ended but almost exclusively nominal lexicon in three languages, which he has learned mainly by reading, with nouns as captions of bi-dimensional images.
