In A. Howes, D. Peebles, and R. Cooper, editors, Proceedings of 9th International Conference on Cognitive Modeling, Manchester, UK, 2009. [ bib | .pdf ]
Previous work has shown that in English ungrammatical center embeddings are more acceptable and easier to process than their grammatical counterparts (Frazier, 1985; Gibson & Thomas, 1999). A well-known explanation for this preference for ungrammatical structures is based on working-memory overload: the claim is that the prediction for an upcoming verb phrase is forgotten due to memory overload, leading to an illusion of grammaticality (Gibson & Thomas, 1999). However, this memory-overload account cannot explain the recent finding by Vasishth, Suckow, Lewis, and Kern (2008) that in German no illusion of ungrammaticality occurs. We present a simple recurrent network model that can explain both the presence of the grammaticality illusion in English and its absence in German. We argue that the grammaticality illusion emerges as a function of experience with language-specific structures, not working memory constraints as argued for in Gibson and Thomas (1999).

In A. Howes, D. Peebles, and R. Cooper, editors, Proceedings of 9th International Conference on Cognitive Modeling, Manchester, UK, 2009. [ bib | .pdf ]
We evaluate the predictions of surprisal and cue-based theory of sentence processing using an eye-tracking corpus, the Potsdam Sentence Corpus. Surprisal is a measure of processing complexity based on a probabilistic grammar and is computed in terms of the total probability of structural options that have been disconfirmed at each input word. The cue-based theory characterizes processing difficulty in terms of working memory costs that derive from decay and interference arising during content-based retrieval requests of previously processed material (e.g., to incrementally build the sentence structure). We show that both surprisal and cue-based parsing independently explain difficulty in sentences processing and interestingly, they have an over-additive effect on processing when combined together.
