“…This follows from an Optimality Theory account, where production proceeds partly independently from comprehension (Smolensky, 1996;Hendriks, 2014Hendriks, , 2016. In this account, the pairing of form with meaning that characterizes linguistic constructions (e.g., Goldberg, 2006) gradually emerges as the by-product of acquiring the constraint ranking of the language. Only when the mapping from an input meaning to the optimal form in production and the mapping from an input form to the optimal meaning in comprehension result in the same form-meaning pairing, as happens under the adult ranking of the constraint but not yet young children's (e.g., Hendriks, 2016), is the result a consistent form-meaning mapping and hence a construction.…”
