Cognitive modeling of individual variation in reference production and comprehension
A challenge for most theoretical and computational accounts of linguistic reference is the observation that language users vary considerably in their referential choices. Part of the variation observed among and within language users and across tasks may be explained from variation in the cognitive resources available to speakers and listeners. This paper presents a computational model of reference production and comprehension developed within the cognitive architecture ACT-R. Through simulations with this ACT-R model, it is investigated how cognitive constraints interact with linguistic constraints and features of the linguistic discourse in speakers’ production and listeners’ comprehension of referring expressions in specific tasks, and how this interaction may give rise to variation in referential choice. The ACT-R model of reference explains and predicts variation among language users in their referential choices as a result of individual and task-related differences in processing speed and working memory capacity. Because of limitations in their cognitive capacities, speakers sometimes underspecify or overspecify their referring expressions, and listeners sometimes choose incorrect referents or are overly liberal in their interpretation of referring expressions

The role of discourse in Italian pronoun interpretation: Investigating variations in experimental results with cognitive modeling
This paper investigates to what extent the variations in experimental results on the interpretation of Italian subject pronouns can be explained by the different discourses used in the experimental studies. A cognitive model implemented in ACT-R was used to simulate pronoun processing and interpretation in discourse, which is influenced by the various contexts used in empirical experiments. Our simulations show that the discourse contexts used in the experiments strongly influence the interpretation of Italian subject pronouns, but not to the extent that all data in different experiments can be explained by it. We therefore conclude with suggestions for further research both on the influence of discourse context and the influence of task on the interpretation of Italian pronouns and (linguistic) experiments in general
The Spray/Load and Dative Alternations: Aligning VP Structure and Contextual Effects.
The theoretical and experimental work presented in this thesis investigates the spray/load and dative alternations. The purpose is to provide a comprehensive analysis of the alternations in terms of their syntactic structures and to account for how contextual information drives differences in the linear order of their VP arguments. This analysis shows that the syntactic structures of the spray/load and dative alternations are identical; each variant in an alternation is characterised by one of two available structures proposed in Janke and Neeleman (2012). Each structure is shown to respect a novel thematic hierarchy that is based on the value of binary feature clusters (Reinhart, 2000) rather than by direct reference to semantic labels. The choice of a particular structure is demonstrated to be affected by the non-semantic context in which the spray/load or dative sentence is generated. This is a consequence of the limited processing capacity of Working Memory and the allocation of attentional resources to a stimulus. Experimental data from an as yet untested variable of the visual context – the egocentric perception of distance – is found to interact with word order preferences of the alternations. I conclude that non-semantic contextual information interacts with the encoding of an event which ultimately has consequences for syntactic choices
