Abstract:The processing difficulty of each word we encounter in a sentence is affected by both our prior linguistic experience and our general knowledge about the world. Computational models of incremental language processing have, however, been limited in accounting for the influence of world knowledge. We develop an incremental model of language comprehension that constructs-on a word-by-word basis-rich, probabilistic situation model representations. To quantify linguistic processing effort, we adopt Surprisal Theory… Show more
“…Alignment is postulated to occur at all linguistic levels, up to situation models. The construction of mental models has further influenced the 'immersed experiencer model' (Zwaan and Ross 2004) (see Barsalou 1999, for a comprehensive overview of perceptual theories of cognition) and probabilistic neurocomputational models of expectation-based comprehension (Venhuizen et al 2018). Research on the interaction of language comprehension with visual attention has been continued in speech perception models (Allopenna et al 1998;Smith et al 2017), in processing accounts of situated sentence comprehension (Altmann and Kamide 2007;Huettig et al 2018;Crocker 2006, 2007), and in computational models of visual attention and situated language comprehension (Crocker et al 2010;Kukona and Tabor 2011;Mayberry et al 2009;Roy and Mukherjee 2005).…”

Predicting variability in context effects is a timely enterprise considering that psycho-and neurolinguistic research has assessed how language processing depends on the perceived context, the body, and long-term linguistic knowledge of the language user. The current evidence suggests that some context effects may be systematically more robust than others and that language user characteristics are an influential modulator of context-sensitive comprehension. Reviewing psycholinguistic evidence, I argue for constrained contextual variability. Variability in context effects is predicted by characteristics of the language user and world-language relations. But extant findings also suggest generalizability beyond such variation, thus imposing constraint on theoretical prediction of context effects via relative (not absolute) processing preferences.

“…Where they differ is in how they represent meaning: Propositional structures (Brouwer, Crocker, Venhuizen, & Hoeks, 2017;Hinaut & Dominey, 2013) identify the agent, patient, and action of a given sentence, that is, they represent the semantic roles and concepts that fill those roles. Situation vectors (Frank & Vigliocco, 2011;Venhuizen, Crocker, & Brouwer, 2019) represent the state-of-affairs in the world as described by the sentence, without any internal role-concept structure. Sentence gestalts (Rabovsky, Hansen, & McClelland, 2018; based on a classical model by McClelland, St.John, & Taraban, 1989) are developed by the neural network itself during training.…”

“…The propositional structure models by Brouwer et al (2017) and Hinaut and Dominey (2013) take this measure to correspond to the well-known P600 EEG component, 4 which is often viewed as indicative of a sentence reinterpretation process. 5 The situation vectors models by Frank and Vigliocco (2011) and Venhuizen et al (2019) show that the amount of change in the network's output can be expressed in terms of word surprisal. Frank and Vigliocco further demonstrate that this predicts simulated wordprocessing time, that is, their model provides a mechanistic account of why higher surprisal leads to longer reading time.…”

Although computational models can simulate aspects of human sentence processing, research on this topic has remained almost exclusively limited to the single language case. The current review presents an overview of the state of the art in computational cognitive models of sentence processing, and discusses how recent sentence-processing models can be used to study bi- and multilingualism. Recent results from cognitive modelling and computational linguistics suggest that phenomena specific to bilingualism can emerge from systems that have no dedicated components for handling multiple languages. Hence, accounting for human bi-/multilingualism may not require models that are much more sophisticated than those for the monolingual case.
“…In this paper, we take the latter approach by building upon previous work by Venhuizen et al [ 33 ] (henceforth, VCB), who put forward a model of language comprehension in which surprisal estimates are derived from the probabilistic, distributed meaning representations that the model constructs on a word-by-word basis. By systematically manipulating the model’s linguistic experience (the linguistic input history of the model) and world knowledge (the probabilistic knowledge captured within the representations), VCB show that, like human comprehenders, the model’s comprehension-centric surprisal estimates are sensitive to both of these information sources.…”

Language is processed on a more or less word-by-word basis, and the processing difficulty induced by each word is affected by our prior linguistic experience as well as our general knowledge about the world. Surprisal and entropy reduction have been independently proposed as linking theories between word processing difficulty and probabilistic language models. Extant models, however, are typically limited to capturing linguistic experience and hence cannot account for the influence of world knowledge. A recent comprehension model by Venhuizen, Crocker, and Brouwer (2019, Discourse Processes) improves upon this situation by instantiating a comprehension-centric metric of surprisal that integrates linguistic experience and world knowledge at the level of interpretation and combines them in determining online expectations. Here, we extend this work by deriving a comprehension-centric metric of entropy reduction from this model. In contrast to previous work, which has found that surprisal and entropy reduction are not easily dissociated, we do find a clear dissociation in our model. While both surprisal and entropy reduction derive from the same cognitive process—the word-by-word updating of the unfolding interpretation—they reflect different aspects of this process: state-by-state expectation (surprisal) versus end-state confirmation (entropy reduction).
