    Abstract

    Infants learn the meaning of words from accumulated experiences of real-time interactions with their caregivers. To study the effects of visual sensory input on word learning, we recorded infant's view of the world using head-mounted eye trackers during free-flowing play with a caregiver. While playing, infants were exposed to novel label-object mappings and later learning outcomes for these items were tested after the play session. In this study we use a classification based approach to link properties of infants' visual scenes during naturalistic labeling moments to their word learning outcomes. We find that a model which integrates both highly informative and ambiguous sensory evidence is a better fit to infants' individual learning outcomes than models where either type of evidence is taken alone, and that raw labeling frequency is unable to account for the word learning differences we observe. Here we demonstrate how a computational model, using only raw pixels taken from the egocentric scene image, can derive insights on human language learning.

    Abstract

    Studies have shown that cross-linguistically, consonants at the left edge of higher-level prosodic boundaries tend to be more forcefully articulated than those at lower-level boundaries, a phenomenon known as domain-initial strengthening. This study tests whether similar effects occur in Turkish, using the Autosegmental-Metrical model proposed by Ipek & Jun [1, 2] as the basis for assessing boundary strength. Productions of /t/ and /d/ were elicited in four domain-initial prosodic positions corresponding to progressively higher-level boundaries: syllable, word, intermediate phrase, and Intonational Phrase. A fifth position, nuclear word, was included in order to better situate it within the prosodic hierarchy. Acoustic correlates of articulatory strength were measured, including closure duration for /d/ and /t/, as well as voice onset time and burst energy for /t/. Our results show that closure duration increases cumulatively from syllable to intermediate phrase, while voice onset time and burst energy are not influenced by boundary strength. These findings provide corroborating evidence for Ipek & Jun’s model, particularly for the distinction between word and intermediate phrase boundaries. Additionally, articulatory strength at the left edge of the nuclear word patterned closely with word-initial position, supporting the view that the nuclear word is not associated with a distinct phrasing domain

    Abstract

    In this study, we compared the performance of a long short-term memory (LSTM) neural network to the behavior of human participants on a language task that requires hierarchically structured knowledge. We show that humans interpret ambiguous noun phrases, such as second blue ball, in line with their hierarchical constituent structure. LSTMs, instead, only do
    so after unambiguous training, and they do not systematically generalize to novel items. Overall, the results of our simulations indicate that a model can behave hierarchically without relying on hierarchical constituent structure.

    Abstract

    Anaphora, a ubiquitous feature of natural language, poses a particular challenge to young children as they first learn language due to its referential ambiguity. In spite of this, parents and caregivers use anaphora frequently in child-directed speech, potentially presenting a risk to effective communication if children do not yet have the linguistic capabilities of resolving anaphora successfully. Through an eye-tracking study in a naturalistic free-play context, we examine the strategies that parents employ to calibrate their use of anaphora to their child's linguistic development level. We show that, in this way, parents are able to intuitively scaffold the complexity of their speech such that greater referential ambiguity does not hurt overall communication success.

    Abstract

    Graph neural networks (GNNs) have emerged as the standard method for numerous tasks on graph-structured data such as node classification. However, real-world graphs are often evolving over time and even new classes may arise. We model these challenges as an instance of lifelong learning, in which a learner faces a sequence of tasks and may take over knowledge acquired in past tasks. Such knowledge may be stored explicitly as historic data or implicitly within model parameters. In this work, we systematically analyze the influence of implicit and explicit knowledge. Therefore, we present an incremental training method for lifelong learning on graphs and introduce a new measure based on k-neighborhood time differences to address variances in the historic data. We apply our training method to five representative GNN architectures and evaluate them on three new lifelong node classification datasets. Our results show that no more than 50% of the GNN's receptive field is necessary to retain at least 95% accuracy compared to training over the complete history of the graph data. Furthermore, our experiments confirm that implicit knowledge becomes more important when fewer explicit knowledge is available.

    Abstract

    COVID-19 research datasets are crucial for analyzing research dynamics. Most collections of COVID-19 research items do not to include cited works and do not have annotations
    from a controlled vocabulary. Starting with ZB MED KE data on COVID-19, which comprises CORD-19, we assemble a new dataset that includes cited work and MeSH annotations for all records. Furthermore, we conduct experiments on the analysis of research dynamics, in which we investigate predicting links in a co-annotation graph created on the basis of the new dataset. Surprisingly, we find that simple heuristic methods are better at
    predicting future links than more sophisticated approaches such as graph neural networks.

    Abstract

    Using the visual-word paradigm, the present study investigated the effects of word onset and offset masking on the time course of non-native spoken-word recognition in the presence of background noise. In two experiments, Dutch non-native listeners heard English target words, preceded by carrier sentences that were noise-free (Experiment 1) or contained intermittent noise (Experiment 2). Target words were either onset- or offset-masked or not masked at all. Results showed that onset masking delayed target word recognition more than offset masking did, suggesting that – similar to natives – non-native listeners strongly rely on word onset information during word recognition in noise.

    Abstract

    There is a strong relation between children’s exposure to
    spatial terms and their later memory accuracy. In the current
    study, we tested whether the production of spatial terms by
    children themselves predicts memory accuracy and whether
    and how language modality of these encodings modulates
    memory accuracy differently. Hearing child speakers of
    Turkish and deaf child signers of Turkish Sign Language
    described pictures of objects in various spatial relations to each
    other and later tested for their memory accuracy of these
    pictures in a surprise memory task. We found that having
    described the spatial relation between the objects predicted
    better memory accuracy. However, the modality of these
    descriptions in sign, speech, or speech-plus-gesture did not
    reveal differences in memory accuracy. We discuss the
    implications of these findings for the relation between spatial
    language, memory, and the modality of encoding.

    Abstract

    Visual and auditory channels have different affordances and
    this is mirrored in what information is available for linguistic
    encoding. The visual channel has high spatial acuity, whereas
    the auditory channel has better temporal acuity. These
    differences may lead to different conceptualizations of events
    and affect multimodal language production. Previous studies of
    motion events typically present visual input to elicit speech and
    gesture. The present study compared events presented as audio-
    only, visual-only, or multimodal (visual+audio) input and
    assessed speech and co-speech gesture for path and manner of
    motion in Turkish. Speakers with audio-only input mentioned
    path more and manner less in verbal descriptions, compared to
    speakers who had visual input. There was no difference in the
    type or frequency of gestures across conditions, and gestures
    were dominated by path-only gestures. This suggests that input
    modality influences speakers’ encoding of path and manner of
    motion events in speech, but not in co-speech gestures.

    Abstract

    Recurrent neural networks (RNNs) have long been an architecture of interest for computational models of human sentence processing. The recently introduced Transformer architecture outperforms RNNs on many natural language processing tasks but little is known about its ability to model human language processing. We compare Transformer- and RNN-based language models’ ability to account for measures of human reading effort. Our analysis shows Transformers to outperform RNNs in explaining self-paced reading times and neural activity during reading English sentences, challenging the widely held idea that human sentence processing involves recurrent and immediate processing and provides evidence for cue-based retrieval.

    Abstract

    This study addresses the question whether visually grounded speech recognition (VGS) models learn to capture sentence semantics without access to any prior linguistic knowledge. We produce synthetic and natural spoken versions of a well known semantic textual similarity database and show that our VGS model produces embeddings that correlate well with human semantic similarity judgements. Our results show that a model trained on a small image-caption database outperforms two models trained on much larger databases, indicating that database size is not all that matters. We also investigate the importance of having multiple captions per image and find that this is indeed helpful even if the total number of images is lower, suggesting that paraphrasing is a valuable learning signal. While the general trend in the field is to create ever larger datasets to train models on, our findings indicate other characteristics of the database can just as important.

    Abstract

    Language emergence is characterized by a high degree of lex-
    ical variation. It has been suggested that the speed at which
    lexical conventionalization occurs depends partially on social
    structure. In large communities, individuals receive input from
    many sources, creating a pressure for lexical convergence.
    In small, insular communities, individuals can remember id-
    iolects and share common ground with interlocuters, allow-
    ing these communities to retain a high degree of lexical vari-
    ation. We look at lexical variation in Kata Kolok, a sign lan-
    guage which emerged six generations ago in a Balinese vil-
    lage, where women tend to have more tightly-knit social net-
    works than men. We test if there are differing degrees of lexical
    uniformity between women and men by reanalyzing a picture
    description task in Kata Kolok. We find that women’s produc-
    tions exhibit less lexical uniformity than men’s. One possible
    explanation of this finding is that women’s more tightly-knit
    social networks allow for remembering idiolects, alleviating
    the pressure for lexical convergence, but social network data
    from the Kata Kolok community is needed to support this ex-
    planation.

    Abstract

    Language is multimodal: non-linguistic cues, such as prosody,
    gestures and mouth movements, are always present in face-to-
    face communication and interact to support processing. In this
    paper, we ask whether and how multimodal cues affect L2
    processing by recording EEG for highly proficient bilinguals
    when watching naturalistic materials. For each word, we
    quantified surprisal and the informativeness of prosody,
    gestures, and mouth movements. We found that each cue
    modulates the N400: prosodic accentuation, meaningful
    gestures, and informative mouth movements all reduce N400.
    Further, effects of meaningful gestures but not mouth
    informativeness are enhanced by prosodic accentuation,
    whereas effects of mouth are enhanced by meaningful gestures
    but reduced by beat gestures. Compared with L1, L2
    participants benefit less from cues and their interactions, except
    for meaningful gestures and mouth movements. Thus, in real-
    world language comprehension, L2 comprehenders use
    multimodal cues just as L1 speakers albeit to a lesser extent.

    Abstract

    Learning verbs is challenging because it is difficult to infer the precise meaning of a verb when there are a multitude of relations that one can derive from a single event. To study this verb learning challenge, we used children's egocentric view collected from naturalistic toy-play interaction as learning materials and investigated how visual and linguistic information provided in individual naming moments as well as cross-situational information provided from multiple learning moments can help learners resolve this mapping problem using the Human Simulation Paradigm. Our results show that learners benefit from seeing children's egocentric views compared to third-person observations. In addition, linguistic information can help learners identify the correct verb meaning by eliminating possible meanings that do not belong to the linguistic category. Learners are also able to integrate visual and linguistic information both within and across learning situations to reduce the ambiguity in the space of possible verb meanings.
