Temporal construal in sentence comprehension depends on linguistically encoded event structure.

How events are ordered in time is one of the most fundamental pieces of information guiding our understanding of the world. Linguistically, this order is often not mentioned explicitly. Here, we propose that the mental construal of temporal order in language comprehension is based on event-structural properties. This prediction is based on a central distinction between states and events both in event perception and language: In perception, dynamic events are more salient than static states. In language, stative and eventive predicates also differ, both in their grammatical behavior and how they are processed. Consistent with our predictions, data from seven pre-registered video-sentence matching experiments, each conducted in English and German (total N = 674), show that people draw temporal inferences based on this difference: States precede events. Our findings not only arbitrate between different theories of temporal language comprehension; they also advance theoretical models of how two different cognitive capacities - event cognition and language - integrate to form a mental representation of time.

Delayed onset facilitates subsequent retrieval of words during language comprehension.

Prior research has shown that during language comprehension, memory representations associated with premodified words (e.g., the injured and dangerous bear) are retrieved faster from memory than those associated with unmodified words (e.g., the bear). Current explanations attribute this effect to the semantic richness of modified words. However, it is not clear whether the presence of modifying words are in fact necessary for a retrieval benefit. Premodifiers necessarily delay the onset of the target word (i.e., bear), and temporal delays may heighten attention to upcoming stimuli, and/or strengthen encoding by producing free time during encoding, facilitating subsequent retrieval. We therefore examined whether a simple delay in the onset of the target can produce a retrieval benefit. Our results show that delayed onset facilitates the subsequent retrieval of target words in the absence of any modifying information. These results lend support to models of language comprehension according to which delays may enhance attention to upcoming words, and also to models of working memory based on which free time replenishes encoding resources, strengthening the memory trace of encoded information and facilitating its retrieval at a subsequent point. Our results also contribute to current memory-based theories of sentence comprehension by showing that retrieval from memory may be affected by nonlinguistic factors such as delay-induced attention enhancement, or free time during encoding.

Effectiveness of a return to work intervention after occupational disability retirement due to depression and anxiety.

Depression and anxiety disorders are the most common cause for disability retirement among people of middle age. The following social disintegration can have an additional detrimental effect on subjects' psychological well-being, which further reduces their chances for recovery. Long-term disability could be avoidable in many cases as depression and anxiety disorders don't have an etiology that makes permanent loss of function inevitable. This prospective cohort study tests the long-term effects of an intervention addressed at these young disablement retirees. Forty-one subjects each in the experimental and control group were followed-up on over a period of 24 months. The intervention had positive effects on psychological well-being. More subjects returned to work than controls. The effects were still present at one year follow-up. These findings show that an individually tailored return-to-work intervention is a useful, sustainable and economically advantageous therapeutic tool to get out of disability retirement due to mental illness even after all other therapeutic tools have failed.

Spontaneous, controlled acts of reference between friends and strangers.

Speakers enjoy considerable flexibility in how they refer to a given referent--referring expressions can vary in their form (e.g., "she" vs. "the cat"), their length (e.g., "the (big) (orange) cat"), and more. What factors drive a speaker's decisions about how to refer, and how do these decisions shape a comprehender's ability to resolve the intended referent? Answering either question presents a methodological challenge; researchers must strike a balance between experimental control and ecological validity. In this paper, we introduce the SCARFS (Spontaneous, Controlled Acts of Reference between Friends and Strangers) Database: a corpus of approximately 20,000 English nominal referring expressions (NREs), produced in the context of a communication game. For each NRE, the corpus lists the concept the speaker was trying to convey (from a set of 471 possible target concepts), formal properties of the NRE (e.g., its length), the relationship between the interlocutors (i.e., friend vs. stranger), and the communicative outcome (i.e., whether the expression was successfully resolved). Researchers from diverse disciplines may use this resource to answer questions about how speakers refer and how comprehenders resolve their intended referent--as well as other fundamental questions about dialogic speech, such as whether and how speakers tailor their utterances to the identity of their interlocutor, how second-degree associations are generated, and the predictors of communicative success.

Lasting effects of the COVID-19 pandemic on language processing.

A central question in understanding human language is how people store, access, and comprehend words. The ongoing COVID-19 pandemic presented a natural experiment to investigate whether language comprehension can be changed in a lasting way by external experiences. We leveraged the sudden increase in the frequency of certain words (mask, isolation, lockdown) to investigate the effects of rapid contextual changes on word comprehension, measured over 10 months within the first year of the pandemic. Using the phonemic restoration paradigm, in which listeners are presented with ambiguous auditory input and report which word they hear, we conducted four online experiments with adult participants across the United States (combined N = 899). We find that the pandemic has reshaped language processing for the long term, changing how listeners process speech and what they expect from ambiguous input. These results show that abrupt changes in linguistic exposure can cause enduring changes to the language system.

A Return-to-Work Intervention for Prematurely Retired Depression or Anxiety Disorder Patients.

Background: Depression and anxiety disorders are the most common cause for premature retirement of people of middle age. These people are expelled from the workforce. The following social disintegration can have an additional detrimental effect on subjects' psychological well-being which further reduces the chance to re-enter the workforce. Depression and anxiety in general need not be regarded as irreversible causes of disability. Therefore, long-term disability should be avoidable in many cases. This two-arm prospective controlled study tests a novel approach for those who have become economically inactive due to their illness with the goal to improve psychological well-being and return to work. Forty-one subjects were followed-up on over a period of 12 months and compared to 41 control cases. ANOVA for repeated measures showed that experimental subjects' psychological well-being and work ability was much better after the intervention than in the control group. These findings show that an individually tailored return-to-work intervention can be a useful therapeutic tool even after retirement.

Shared syntax between comprehension and production: Multi-paradigm evidence that resumptive pronouns hinder comprehension.

Language comprehension and production are generally assumed to use the same representations, but resumption poses a problem for this view: This structure is regularly produced, but judged highly unacceptable. Production-based solutions to this paradox explain resumption in terms of processing pressures, whereas the Facilitation Hypothesis suggests resumption is produced to help listeners comprehend. Previous research purported to support the Facilitation Hypothesis did not test its keystone prediction: that resumption improves accuracy of interpretation. Here, we test this prediction directly, controlling for factors that previous work did not. Results show that resumption in fact hinders comprehension in the same sentences that native speakers produced, a finding which replicated across four high-powered experiments with varying paradigms: sentence-picture matching (N=300), self-paced reading (N=96), visual world eye-tracking (N=96), and multiple-choice comprehension question (N=150). These findings are consistent with production-based accounts, indicating that comprehension and production may indeed share representations, although our findings point toward a limit on the degree of overlap. Methodologically speaking, the findings highlight the importance of measuring interpretation when studying comprehension.

Identifying Individuals at High Risk for Permanent Disability From Depression and Anxiety.

Mental illnesses, among which depression and anxiety are most common, are the leading cause for permanent disability. It is of interest to know what case characteristics determine if a person returns to the work force in spite of mental illness to tailor specific interventions. So far, there has been little research into this field. In the present study a sample of 202 workers who had permanent disability due to depression/anxiety were followed-up on. 22% started some kind of work during follow-up in a period of 30 to 75 months. Logistic regression analyses showed that quick progression into disability, short period of disability, younger age, adequacy of income replacement through insurance benefits and no previous disability predicted return to work. These findings also allow to identify individuals at high risk for progression into permanent disability that can benefit from supporting interventions.

Sheer Time Spent Expecting or Maintaining a Representation Facilitates Subsequent Retrieval during Sentence Processing.

Previous research has shown that modified noun phrases (henceforth NPs) are subsequently retrieved faster than unmodified NPs. This effect is often called the "semantic complexity effect". However, little is known about its mechanisms and underlying factors. In this study, we tested whether this effect is truly caused by the semantic information added by the modification, or whether it can be explained by the sheer amount of time that the processor spends expecting or maintaining an NP in the encoding phase. The results showed that time spent expecting or maintaining an NP can explain the effect over and above semantic and/or syntactic complexity. Our results challenge the current memory-based mechanisms for the modification effect such as the "distinctiveness" and "head-reactivation" accounts, and offer new and valuable insight into the memory processes during sentence comprehension.

Event Structures Drive Semantic Structural Priming, Not Thematic Roles: Evidence From Idioms and Light Verbs.

What are the semantic representations that underlie language production? We use structural priming to distinguish between two competing theories. Thematic roles define semantic structure in terms of atomic units that specify event participants and are ordered with respect to each other through a hierarchy of roles. Event structures instead instantiate semantic structure as embedded sub-predicates that impose an order on verbal arguments based on their relative positioning in these embeddings. Across two experiments, we found that priming for datives depended on the degree of overlap in event structures. Specifically, while all dative structures showed priming, due to common syntax, there was a boost for compositional datives priming other compositional datives. Here, the two syntactic forms have distinct event structures. In contrast, there was no boost in priming for dative light verbs, where the two forms map onto a single event representation. On the thematic roles hypothesis, we would have expected a similar degree of priming for the two cases. Thus, our results support event structural approaches to semantic representation and not thematic roles.

Investigating Thematic Roles through Implicit Learning: Evidence from Light Verb Constructions.

The syntactic structure of a sentence is usually a strong predictor of its meaning: Each argument noun phrase (i.e., Subject and Object) should map onto exactly one thematic role (i.e., Agent and Patient, respectively). Some constructions, however, are exceptions to this pattern. This paper investigates how the syntactic structure of an utterance contributes to its construal, using ditransitive English light verb constructions, such as "Nils gave a hug to his brother," as an example of such mismatches: Hugging is a two-role event, but the ditransitive syntactic structure suggests a three-role event. Data from an eye-tracking experiment and behavioral categorization data reveal that listeners learn to categorize sentences according to the number of thematic roles they convey, independent of their syntax. Light verb constructions, however, seem to form a category of their own, in which the syntactic structure leads listeners down an initial incorrect assignment of thematic roles, from which they only partly recover. These results suggest an automatic influence of syntactic argument structure on semantic interpretation and event construal, even in highly frequent constructions.

If you want a quick kiss, make it count: How choice of syntactic construction affects event construal.

When we hear an event description, our mental construal is not only based on lexical items, but also on the message's syntactic structure. This has been well-studied in the domains of causation, event participants, and object conceptualization. Less studied are the construals of temporality and numerosity as a function of syntax. We present a theory of how syntax affects the construal of event similarity and duration in a way that is systematically predictable from the interaction of mass/count syntax and verb semantics, and test these predictions in six studies. Punctive events in count syntax (give a kiss) and durative events in mass syntax (give advice) are construed as taking less time than in transitive frame (kiss and advise). Durative verbs in count syntax (give a talk), however, result in a semantic shift, orthogonal to duration estimates. These results demonstrate how syntactic and semantic structure together systematically affect event construal.

Priming is swell, but it's far from simple.

Clearly, structural priming is a valuable tool for probing linguistic representation. But we don't think that the existing results provide strong support for Branigan & Pickering's (B&P's) model, largely because the priming effects are more confusing and diverse than their theory would suggest. Fortunately, there are a number of other experimental tools available, and linguists are increasingly making use of them.

Linear grammar as a possible stepping-stone in the evolution of language.

We suggest that one way to approach the evolution of language is through reverse engineering: asking what components of the language faculty could have been useful in the absence of the full complement of components. We explore the possibilities offered by linear grammar, a form of language that lacks syntax and morphology altogether, and that structures its utterances through a direct mapping between semantics and phonology. A language with a linear grammar would have no syntactic categories or syntactic phrases, and therefore no syntactic recursion. It would also have no functional categories such as tense, agreement, and case inflection, and no derivational morphology. Such a language would still be capable of conveying certain semantic relations through word order-for instance by stipulating that agents should precede patients. However, many other semantic relations would have to be based on pragmatics and discourse context. We find evidence of linear grammar in a wide range of linguistic phenomena: pidgins, stages of late second language acquisition, home signs, village sign languages, language comprehension (even in fully syntactic languages), aphasia, and specific language impairment. We also find a full-blown language, Riau Indonesian, whose grammar is arguably close to a pure linear grammar. In addition, when subjects are asked to convey information through nonlinguistic gesture, their gestures make use of semantically based principles of linear ordering. Finally, some pockets of English grammar, notably compounds, can be characterized in terms of linear grammar. We conclude that linear grammar is a plausible evolutionary precursor of modern fully syntactic grammar, one that is still active in the human mind.

Action starring narratives and events: Structure and inference in visual narrative comprehension.

Studies of discourse have long placed focus on the inference generated by information that is not overtly expressed, and theories of visual narrative comprehension similarly focused on the inference generated between juxtaposed panels. Within the visual language of comics, star-shaped "flashes" commonly signify impacts, but can be enlarged to the size of a whole panel that can omit all other representational information. These "action star" panels depict a narrative culmination (a "Peak"), but have content which readers must infer, thereby posing a challenge to theories of inference generation in visual narratives that focus only on the semantic changes between juxtaposed images. This paper shows that action stars demand more inference than depicted events, and that they are more coherent in narrative sequences than scrambled sequences (Experiment 1). In addition, action stars play a felicitous narrative role in the sequence (Experiment 2). Together, these results suggest that visual narratives use conventionalized depictions that demand the generation of inferences while retaining narrative coherence of a visual sequence.

The difference between "giving a rose" and "giving a kiss": Sustained neural activity to the light verb construction.

We used event-related potentials (ERPs) to investigate the neurocognitive mechanisms associated with processing light verb constructions such as "give a kiss". These constructions consist of a semantically underspecified light verb ("give") and an event nominal that contributes most of the meaning and also activates an argument structure of its own ("kiss"). This creates a mismatch between the syntactic constituents and the semantic roles of a sentence. Native speakers read German verb-final sentences that contained light verb constructions (e.g., "Julius gave Anne a kiss"), non-light constructions (e.g., "Julius gave Anne a rose"), and semantically anomalous constructions (e.g., *"Julius gave Anne a conversation"). ERPs were measured at the critical verb, which appeared after all its arguments. Compared to non-light constructions, the light verb constructions evoked a widely distributed, frontally focused, sustained negative-going effect between 500 and 900 ms after verb onset. We interpret this effect as reflecting working memory costs associated with complex semantic processes that establish a shared argument structure in the light verb constructions.
