 In a very thorough subsequent study, Bresnan and Ford (2010) show that the results also correlate with native speakers’ metalinguistic judgments of naturalness for sentence structures, and with lexical decision latencies (speed of deciding whether the words in a text were genuine English words or not), and with a sentence completion task (choosing the most natural of a list of possible completions of a partial sentence). The results of these experiments confirmed that their model predicted participants’ performance.
