Language comprehension represents a relative strength for individuals with Down syndrome (DS), particularly in vocabulary as opposed to syntax, yet difficulties have been highlighted in areas of pragmatics. Despite issues with recall, studies investigating storytelling report sensitivity to the causal structures of narratives, while poor inferencing skills may be associated with cognitive and expressive deficits. This study investigated inferential abilities in 26 English-speaking adolescents and adults with DS and 24 vocabulary-matched typical controls. Inferencing abilities were assessed through the LITMUS MAIN comprehension task, which targeted understanding of characters’ goals and internal states. Poorer general comprehension scores we observed in DS. This suggests that individuals with DS show deficits in understanding, and potentially expressing inferential information relating to characters mental states. Age, executive functioning and grammar comprehension did not show a significant contribution to comprehension. We consider the role of matching and discuss potential implications for future research

The 46th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Languages differ in what meanings their lexical items encode: The meaning covered by English 'blue' is famously split into 'sinij' (darkblue) and 'goluboj' (lightblue) in Russian. Recent years have seen novel interest in functional explanations of such variation, pointing to a correlation between greater communicative need of a lexical field and a finer-grained lexical inventory. Here, I develop the position that rather than the mere difference in “need” to mention lexical field, it is the field’s discourse-pragmatic diversity that predicts whether languages “lump” or “split” more. I will demonstrate this with computational techniques and a typologically diverse corpus of spontaneous spoken data from 51 languages (DoReCo), first for the field of verbs of visual perception ('see'-'look'), then on a lexicon-wide level. There are implications: our notions of what a comparable concept is in lexical semantics, what lexical knowledge entails, and the dimensions along which languages differ require re-examining.

Lexicons encode differently what people do differently. Computational studies of the pragmatic motivations of lexical typology.

Languages vary in the ways they package the conceptual components of motion events into verbs. In a series of experiments, we examined the use of event-general conceptual categories of MANNER and RESULT during verb learning. We tested the accessibility of these concepts within and across domains of spontaneous motion and caused motion events, in speakers of typologically different languages (English and Spanish). Our results indicate that learners can adapt new lexicalization biases that may differ from those present in their own native language, and generalize them to novel instances of the same class of verbs. Furthermore, our data also indicate that under certain contexts, learners can transfer these newly learned biases to a different event domain, suggesting that event-general conceptual categories are psychologically available to learners.

Event-General Conceptual Categories Organize Verb Semantics and Acquisition Cross-linguistically

Conversation requires a substantial amount of coordination between dialogue participants, from managing turn taking to negotiating mutual understanding. Part of this coordination effort surfaces as the reuse of linguistic behaviour across speakers, a process often referred to as alignment. While the presence of linguistic alignment is well documented in the literature, several questions remain open, including the extent to which patterns of reuse across speakers have an impact on the emergence of labelling conventions for novel referents. In this study, we put forward a methodology for automatically detecting shared lemmatised constructions---expressions with a common lexical core used by both speakers within a dialogue---and apply it to a referential communication corpus where participants aim to identify novel objects for which no established labels exist. Our analyses uncover the usage patterns of shared constructions in interaction and reveal that features such as their frequency and the amount of different constructions used for a referent are associated with the degree of object labelling convergence the participants exhibit after social interaction. More generally, the present study shows that automatically detected shared constructions offer a useful level of analysis to investigate the dynamics of reference negotiation in dialogue.

Analysing Cross-Speaker Convergence through the Lens of Automatically Detected Shared Linguistic Constructions

When we communicate with others, we often repeat aspects of each other’s communicative behavior such as sentence structures and words. Such behavioral alignment has been mostly studied for speech or text. Yet, language use is mostly multimodal, flexibly using speech and gestures to convey messages. Here, we explore the use of alignment in speech (words) and co-speech gestures (iconic gestures) in a referential communication task aimed at finding labels for novel objects in interaction. In particular, we investigate how people flexibly use lexical and gestural alignment to create shared labels for novel objects and whether alignment in speech and gesture are related over time. The present study shows that interlocutors not only establish shared labels multimodally but also keep aligning in words and iconic gestures over the interaction. We also show that the amount of lexical alignment positively correlates with the amount of gestural alignment over time, suggesting a close relationship between alignment in the vocal and manual modalities.

Speakers align both their gestures and words not only to establish but also to maintain reference to create shared labels for novel objects in interaction

Sentences that consist of multiple clauses generally contain one clause that carries the main (at-issue) point, and other clauses whose content is more peripheral (not-at-issue). Which clause carries the at-issue point is expected to be influenced by whether a clause is at the Right Frontier: Last-uttered clauses or clauses that subordinates the last-uttered clause are expected to be a possible host for at-issue content. We report the results of a Dutch forced-choice experiment in which we measured the rate at which comprehenders interpreted an ambiguous pronoun to refer to one of two possible antecedents. We manipulated the type of clause in which each antecedent appeared (matrix vs.~subordinate) and the position of the clauses (sentence-early vs.~sentence-final). We find that independent of position, matrix clauses were more often interpreted as at-issue than ARCs, but that clauses in sentence-final position were more often interpreted as at-issue than clauses in sentence-early position.

At-issueness and the Right Frontier: An Investigation of Dutch

Gricean maxims prescribe cooperative speakers to make their utterances maximally informative so that listeners have the highest chance of understanding the utterances as intended. At the same time, speakers are expected to save articulatory effort and not produce descriptions that are more explicit than necessary. In this work, we first ask how predictability of the described events affects the choice of anaphoric references. We show that speakers prefer phonologically overt descriptions, such as definite NPs, when they refer to agents that behave in an unexpected way. We further test how the interpretation of references changes depending on the listening conditions (low vs.~high noise) and prior expectations about the plausibility of an event. Our work shows that the speaker's extra effort in choosing a more phonologically overt reference is justified by listeners' behavior: they report having heard an utterance which is more plausible than the originally spoken utterance and which contains additional phonological material.

Interpreting implausible event descriptions under noise

The default null hypothesis in typical statistical modelling software is that a parameter's value is equal to zero. However, this may not always correspond to the actual conditions that would hold if the effect of interest did not exist. In two case studies based on recent research in cognitive science and linguistics, we illustrate how data simulation can shed light on unspoken, sometimes even incorrect, assumptions about what the null hypothesis is. In particular, we consider two experiment-specific measures of changes in probability distributions where the null condition is not always equal to zero change; and an investigation of a cognitive bias for skewed distributions based on the assumption that, without such a bias, distributions would always remain uniform. All in all, simulating null conditions not only improves each researcher's understanding of their own analysis and results, but also contributes to the practice of "open theory". Formalising one's assumptions is, in itself, an important contribution to the scientific community.

Simulation as a tool for formalising null hypotheses in cognitive science research

Natural languages show a tendency to minimize the linear distance between heads and their dependents in a sentence, known as dependency length minimization (DLM). Such a preference, however, has not been consistently replicated with neural agent simulations. Comparing the behavior of models with that of human learners can reveal which aspects affect the emergence of this phenomenon. In this work, we investigate the minimal conditions that may lead neural learners to develop a DLM preference. We add three factors to the standard neural-agent language learning and communication framework to make the simulation more realistic, namely: (i) the presence of noise during listening, (ii) context-sensitivity of word use through non-uniform conditional word distributions, and (iii) incremental sentence processing. While no preference appears in production, we show that the proposed factors contribute to a small but consistent learning advantage of DLM for listeners of verb-initial languages.

Neural-agent Language Learning and Communication: Emergence of Dependency Length Minimization

How children acquire the rules governing past tense production has been for many years a test bed case for nativist-constructivist debates about the nature of innate knowledge and its role in language acquisition. However, previous studies have tested the acquisition of past tense via corpus analysis, in which errors are rare, or elicitation tasks, in which tested items are few, resulting in limited between-item variability. To address these weaknesses, we analysed data from a uniquely large and longitudinal dataset containing 694 verbs, collected via an educational online platform. We examined whether form-frequency, phonological neighbourhood density (PND), and telicity predict the verb-level difficulty of past tense forms in Dutch. Our sample consists of Dutch-speaking children aged 8-12 years old, the age at which children are still making past tense over-regularisation errors. Analyses are ongoing but preliminary results suggest a role for all three factors and an interaction between frequency and PND.

Item-level Difficulty Predictors in the Acquisition of Past Tense in Dutch

We study repair in child-directed speech (CDS) and child speech (CS) in longitudinal corpora of 4 languages: English, Russian, Chintang and Indonesian (age range 2;01-3;04). We distinguish: open requests (whole utterance unclear, 'huh?'), restricted requests (utterance partly unclear, 'you saw what yesterday?'), and restricted offers (confirmation requested, 'you saw a film?') (Dingemanse et al., 2015). 
Our results indicate that only restricted offers in CDS are significant for predicting the respective types in CS. We therefore suggest that open and restricted requests are more dependent on children's socio-cognitive development, whereas restricted offers rely more on input distributions. Restricted offers are also used by caregivers to correct or provide feedback, and this investment in language teaching differs greatly across cultures (e.g., 72.4% in Russian CDS but only 22% in Chintang). We propose that acquisition of repairs in children relies both on socio-cognitive abilities and input distributions.
