  1. Alasdair Daniel Francis Clarke, Moreno I. Coco & Frank Keller (2013). The Impact of Attentional, Linguistic and Visual Features During Object Naming. Frontiers in Psychology 4:927.
    Object detection and identification are fundamental visual tasks and recent work suggests that it is primarily objects, rather than low-level salient regions, that attract our attention. This raises the question of which objects are important in the context of a visual scene. The current eye-tracking study investigates how different features (attentional, visual and linguistic) influence the likelihood that a given object in a scene will be named. We carried out an object naming task involving 24 participants and 100 photographic images (...)

    Probabilistic models of sentence comprehension are increasingly relevant to questions concerning human language processing. However, such models are often limited to syntactic factors. This restriction is unrealistic in light of experimental results suggesting interactions between syntax and other forms of linguistic information in human sentence processing. To address this limitation, this article introduces two sentence processing models that augment a syntactic component with information about discourse co-reference. The novel combination of probabilistic syntactic components with co-reference classifiers permits them to more (...)

  3. Stella Frank, Sharon Goldwater & Frank Keller (2013). Adding Sentence Types to a Model of Syntactic Category Acquisition. Topics in Cognitive Science 5 (3):495-521.
    The acquisition of syntactic categories is a crucial step in the process of acquiring syntax. At this stage, before a full grammar is available, only surface cues are available to the learner. Previous computational models have demonstrated that local contexts are informative for syntactic categorization. However, local contexts are affected by sentence-level structure. In this paper, we add sentence type as an observed feature to a model of syntactic category acquisition, based on experimental evidence showing that pre-syntactic children are able (...)

  4. Moreno I. Coco & Frank Keller (2012). Scan Patterns Predict Sentence Production in the Cross-Modal Processing of Visual Scenes. Cognitive Science 36 (7):1204-1223.
    Most everyday tasks involve multiple modalities, which raises the question of how the processing of these modalities is coordinated by the cognitive system. In this paper, we focus on the coordination of visual attention and linguistic processing during speaking. Previous research has shown that objects in a visual scene are fixated before they are mentioned, leading us to hypothesize that the scan pattern of a participant can be used to predict what he or she will say. We test this hypothesis (...)

  5. David Reitter, Frank Keller & Johanna D. Moore (2011). A Computational Cognitive Model of Syntactic Priming. Cognitive Science 35 (4):587-637.
    The psycholinguistic literature has identified two syntactic adaptation effects in language production: rapidly decaying short-term priming and long-lasting adaptation. To explain both effects, we present an ACT-R model of syntactic priming based on a wide-coverage, lexicalized syntactic theory that explains priming as facilitation of lexical access. In this model, two well-established ACT-R mechanisms, base-level learning and spreading activation, account for long-term adaptation and short-term priming, respectively. Our model simulates incremental language production and in a series of modeling studies, we show (...)
