Misinterpretations in agreement and agreement attraction

It has been well established that subject–verb number agreement can be disrupted by local noun phrases that differ in number from the subject head noun phrase. In sentence production, mismatches in the grammatical number of the head and local noun phrases lead to agreement errors on the verb as in: the key to the cabinets are. Similarly, although ungrammaticality typically causes disruption in measures of sentence comprehension, the disruption is reduced when the local noun phrase has a plural feature. Using a forced-choice comprehension question method, we report two experiments that provide evidence that comprehenders were likely to misinterpret the number information on the head noun phrase when morphosyntactic number markings on the local noun phrase and verb did not match the head. These results are consistent with a growing body of research that suggests that comprehenders often arrive at a final interpretation of a sentence that is not faithful to the linguistic input.

The role of selection in the comprehension of focus alternatives

ABSTRACT Successful language comprehension often requires comprehenders to infer contrastive focus alternatives, but the mechanisms used to establish contrastive alternatives are still poorly understood. We propose that comprehenders establish contrastive alternatives by using selection mechanisms that distinguish contrastive from non-contrastive candidates. To examine this proposal, we investigated the time course of contrastive alternatives in two cross-modal priming experiments, manipulating contrastive focus on prime words and the contrastiveness of visual targets. Experiment 1 examined early processing where comprehenders are entertaining candidates for contrastive alternatives. Experiment 2 examined later processing where comprehenders have selected contrastive alternatives from the candidate set. Results demonstrated that when primes were contrastively focused, initially both contrastive and non-contrastive associates were facilitated, but, in subsequent processing, non-contrastive associates became deactivated while contrastive associates maintained facilitation. We argue that selection mechanisms distinguish contrastive from non-contrastive candidates by deactivating non-contrastive candidates, enabling comprehenders to draw proper inferences about speakers’ implicit meanings.

Limits on prediction in language comprehension: A multi-lab failure to replicate evidence for probabilistic pre-activation of phonology

In current theories of language comprehension, people routinely and implicitly predict upcoming words by pre-activating their meaning, morpho-syntactic features and even their specific phonological form. To date the strongest evidence for this latter form of linguistic prediction comes from a 2005 Nature Neuroscience landmark publication by DeLong, Urbach and Kutas, who observed a graded modulation of article- and noun-elicited electrical brain potentials (N400) by the pre-determined probability that people continue a sentence fragment with that word (‘cloze’). In a direct replication study spanning 9 laboratories (N=334), we failed to replicate the crucial article-elicited N400 modulation by cloze, while we successfully replicated the commonly-reported noun-elicited N400 modulation. This pattern of failure and success was observed in a pre-registered replication analysis, a pre-registered single-trial analysis, and in exploratory Bayesian analyses. Our findings do not support a strong prediction view in which people routinely pre-activate the phonological form of upcoming words, and suggest a more limited role for prediction during language comprehension.

Large-scale replication study reveals a limit on probabilistic prediction in language comprehension

Do people routinely pre-activate the meaning and even the phonological form of upcoming words? The most acclaimed evidence for phonological prediction comes from a 2005 Nature Neuroscience publication by DeLong, Urbach and Kutas, who observed a graded modulation of electrical brain potentials (N400) to nouns and preceding articles by the probability that people use a word to continue the sentence fragment (‘cloze’). In our direct replication study spanning 9 laboratories (N=334), pre-registered replication-analyses and exploratory Bayes factor analyses successfully replicated the noun-results but, crucially, not the article-results. Pre-registered single-trial analyses also yielded a statistically significant effect for the nouns but not the articles. Exploratory Bayesian single-trial analyses showed that the article-effect may be non-zero but is likely far smaller than originally reported and too small to observe without very large sample sizes. Our results do not support the view that readers routinely pre-activate the phonological form of predictable words.

Building Aspectual Interpretations Online

Linguistic events have long been known to systematically differ with respect to whether they proceed to a natural and necessary end point, or not. Semantic and syntactic accounts of these systematic differences disagree as to which kind of event is more complex, and thus more computationally costly, but both approaches identify the VP (not the verb alone) as the domain for aspectual interpretation. We review the existing processing literature, which is broadly consistent with VP-domain hypotheses but does not address the issue of representational complexity. We present a series of experiments that provide a more detailed look at the time course of aspectual interpretation, providing clear support for the VP hypothesis. We also argue that syntactic and semantic complexity effects can be seen in aspectual processing. Terminative syntactic structure and durative semantic interpretation are both costly.

Dissociable effects of prediction and integration during language comprehension: Evidence from a large-scale study using brain potentials

Composing sentence meaning is easier for predictable words than for unpredictable words. Are predictable words genuinely predicted, or simply more plausible and therefore easier to integrate with sentence context? We addressed this persistent and fundamental question using data from a recent, large-scale (N = 334) replication study, by investigating the effects of word predictability and sentence plausibility on the N400, the brain’s electrophysiological index of semantic processing. A spatiotemporally fine-grained mixed-effects multiple regression analysis revealed overlapping effects of predictability and plausibility on the N400, albeit with distinct spatiotemporal profiles. Our results challenge the view that semantic facilitation of predictable words reflects the effects of either prediction or integration, and suggest that facilitation arises from a cascade of processes that activate and integrate word meaning with context into a sentence-level meaning.

Speaking of death

As a human-specific trait, language offers a unique window on human cognition. Grammatical constraints on the ways we speak about events, for instance, have long been thought to reveal the representational formats that our minds impose on the ways that we think about events. In recent research, verbs that name events of death have stood out as key counterexamples to standard theories of the grammatical constraints on possible verbs. The special status of these thanatological verbs raises two important questions: why, given the vast number of verbs in any language, is it that verbs of death hold this special status, and what do they tell us about the restrictions on the representational format for possible verbs? This paper reexamines the evidence coming from verbs of death, confirming that they are counterexamples to standard theories, but that their behaviour suggests a more revealing constraint on our mental representations—that our minds impose strict restrictions on the format of asserted meaning. Thus, the constraints on linguistic representation and the human mind offer a unique perspective on the mental representations of thanatological phenomena.
