Abstract

In this response to commentators on our target article ‘Child language acquisition: Why universal grammar doesn't help’, we argue that the fatal flaw in most UG-based approaches to acquisition is their focus on describing the adult end-state in terms of a particular linguistic formalism. As a consequence, such accounts typically neglect to link acquisition to the language that the learner actually hears, instead assuming that she is able, by means usually unspecified, to perceive her input in terms of high-level theoretical abstractions.
