Bipolar disorder (BD) is a mental health condition
characterized by large fluctuations in goal-directed energy and
mood. BD is defined by the presence of at least one lifetime
episode of mania, a prolonged period of excessive goaldirected
behavior, hyperactivity and elevated mood. In this
work, we use reinforcement learning (RL), a principled model
of goal-directed behavior and learning, to show how augmenting
RL agents with dynamic self-efficacy beliefs can give rise to
a range of symptoms characteristic of the mania phase of BD.
Our simulations demonstrate that a model-free RL agent that
dynamically updates its self-efficacy beliefs learns optimistic
overgeneralized value representations. We suggest that these
representations may underlie several behaviors associated with
mania, such as increased motivational drive and faster initiation
of approach behavior (i.e. impatience). We further show
that agents with more sensitive self-efficacy beliefs display increased
willingness to exert effort in order to achieve higher
goals even in the face of costs, a characteristic that is observed
in individuals at risk for BD. Finally, unrealistically high selfefficacy
beliefs that emerged with learning were accompanied
by behaviors such as distractibility and compulsive action selection
that have clinical parallels to symptoms of mania.

Dynamic self-efficacy updating as a computational mechanism of mania emergence

## Welcome to 2024 Annual Conference of the North American Chapter of the Association for Computational Linguistics!
This year, the conference is in Mexico City. NAACL was actually already planned for Mexico City in 2021, but due to the pandemic the entire conference was moved online. This year, finally, we get to go! So it is my sincere pleasure to welcome you to Mexico City, whether in person or virtually. Having the conference in Mexico City is a good opportunity to emphasize that NAACL is our flagship conference for ACL members not only in North America but also in Central and South America, even though NAACL has been bearing “North” in its name. At this year’s conference, we have a theme to match, with a theme track on the Languages of Latin America to showcase the linguistic diversity of the region.
 
The opportunity to present at NAACL should not depend on a researcher’s travel budget, or their family status. This is why it is so important to make virtual participation at NAACL as good an experience as possible – but we want to also provide a good experience for in-person participants. As a community, we are still working out the best way to do that. This year at NAACL, we are trying out a big virtual poster session ahead of the conference, with the hope that this will make make for a lively and interactive experience. At the same time, we are reducing virtual oral presentations, which seem to be particularly tricky to make to work well. A big thanks to the NAACL program chairs and to Luciana Benotti for all their ideas and work to improve the virtual experience. And participants, virtual as well as in-person: Please let us know what worked for you and what didn’t, so we can continue to improve hybrid conferences. 
 
I have been lucky to work with many amazing people. Without their insight, dedication and patience, and without the many hours of work they put in, NAACL would not have been possible. A huge thank you to the program chairs Helena Gomez, Kevin Duh, and Steve Bethard – you are the best! 
 
Finally, I would like to thank all authors, invited speakers and panelists, area chairs and reviewers, the volunteers organizing and chairing sessions, and all attendees, in-person and virtual. Thank you for helping us make NAACL 2024 come to life. 
 
Welcome and hope you all enjoy the conference!

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

To fully grasp the underlying behavioral and neural processes of social cognition, it has been argued that interactive experimental paradigms and multi-person neuroimaging are needed. However, few studies have examined group interactions, beyond the dyad, as well as how higher-level social properties map onto coordination dynamics. Here, we investigated the role of friendship in group social coordination, by mapping student social networks, and recruiting groups of participants by manipulating their friendship strength. Participants were tasked with pressing their own individual pressure measuring (force) device to reach a designated target force together in groups of three (two friends, one non-friend), with or without live visual feedback, whilst three-person EEG hyperscanning was employed. Preliminary behavioral results indicate that lack of friendship with the other two participants results in greater force production relative to the other participants. We plan to explore the relationship between the social, behavioral, and neural dynamics.

The role of friendship in dynamic group coordination

The neural entrainment paradigm (Batterink & Paller, 2017) extended to infant statistical learning (SL; Choi, Batterink, Black, Paller, &Werker, 2020) provides a continuous, implicit measure of learning as infants are exposed to a syllable sequence in a classic word embedding paradigm (cf. Saffran, Aslin, & Newport, 1996). We investigated the potential for feedforward multi-layer perceptrons (MLPs) and Simple Recurrent Networks (SRNs; e.g., Elman, 1990, 1991) to simulate neural entrainment in statistical learning (SL). Similar to human SL, these artificial neural networks are capable of attuning to sequential regularities. We trained MLPs and SRNs on items based on those from Choi et al. (2020), with four 3-syllable word-like patterns in random order. The models’ task was to predict the next syllable given the current syllable. We transformed the model’s initial discrete activation per second into a continuous time-domain signal, expanding them into 1000 samples. Syllable rate was 3Hz, so word rate was 1Hz. Treating nodes like EEG channels, we applied standard neural entrainment analyses that assess phase-locked responses to stimulus characteristics (using Inter-Trial Coherence, or ITC). Both MLPs and SRNs exhibited human-like entrainment, with early entrainment to syllable frequency and later entrainment to word frequency, although only SRNs exhibited a human-like significant correlation between the relative strength of word vs. syllable ITC and preferences for word-like patterns after training. Later entrainment to word-rate is typically interpreted as an index of SL, on the logic that such entrainment emerges as the learner develops representations of word-like patterns. However, we also found ITC at syllable and word rate when we pushed the raw input sequence through our pipeline (with no learning, just a pattern of activations over localist input nodes). We discuss implications for theories of SL as well as interpreting neural entrainment.

Modeling infant cortical tracking of statistical learning in simple recurrent networks

Accumulating behavioral and electrophysiological evidence demonstrates the effects of sentence context on word processing. However, there is a relative scarcity of research investigating both global and local effects during processing, particularly in terms of the influence of grammatically constraining and semantically selectional components, such as Chinese classifiers, as local (in)congruency. In this study, we manipulated congruency between global sentence context and head nouns, as well as congruency between classifiers and head nouns in highly constraining Chinese sentences using a two-by-two factorial design. The results revealed that the semantic and grammatical feature of highly predicted nouns can be pre-activated in advance of the bottom-up input. In addition, both global sentence context and local classifier-noun congruency significantly influenced head noun processing, with neither factor exhibiting overwhelming strength over the other. Both global and local information can be integrated during lexical processing.

The influence of global context and classifier-noun congruency on Chinese predictive sentence processing

The experiment reported here investigated the neural correlates of predictive processing of angry and neutral speech. Twenty-six participants listened to recordings of angry and neutral conversation segments, as well as to speech-shaped noise, while their EEG was recorded. Oscillatory power in the gamma band (30–80 Hz) and the N400 component of event-related potentials (ERP) to sentence-final words were analyzed. In comparison to neutral words, negative emotional valence significantly reduced the amplitude of the N400 elicited by sentence-final words. Furthermore, there was larger gamma power during exposure to angry speech in comparison to neutral speech. The results generally suggest increased prediction and facilitated semantic integration in negative as compared to neutral speech. To date, the predictability effects on gamma power have been reported with relation to the semantic-lexical content of words. The present findings demonstrate that gamma power is also modulated by the emotional content of speech.

Neural oscillatory and ERP indices of prediction in emotional speech

This paper presents a case study of a 10-year-old Chinese-English bilingual boy, who has developmental dyslexia and exhibits a discrepancy in reading and writing skills between the two languages. This discrepancy is believed to be influenced by the different orthographic characteristics and cognitive demands of the two languages. The study investigated the reasons behind his literacy skills profile from both orthographic and cognitive perspectives. To achieve this, the researchers assessed the boy’s literacy skills, receptive vocabulary, and cognitive abilities (including phonological skills, naming speed, and visual skills) in both Chinese and English. The preliminary results showed that the bilingual child’s reading skills in English were on par with bilingual children, although lower than English monolingual children. This case study supports the cognitive account theory, suggesting that the different cognitive demands required for literacy skill development can lead to discrepancies in these skills, particularly in terms of accuracy, in bilingual children.

Influence of cognitive abilities on literacy skills in a Chinese-English bilingual child with developmental dyslexia

Human communication, known to occur between two individuals using various modalities, has attracted significant interest, particularly in the context of neural dynamics’ studies. Embodied communication, especially in cooperative or competitive scenarios, has been a focal point of these studies. However, the neural activity during this process is not well understood from the viewpoint of motor intention in communication. It is crucial to note that intentional motor switching occurs following motor coordination within a pair. In this study, we conducted a simultaneous recording of EEG, motion, and gaze of two players engaged in our newly devised coordination game involving bodily motions. We observed significant differences in time-frequency power during cooperative and competitive situations in intentional motor switching. This finding suggests that the EEG power differences in local brain regions and in the alpha and high frequency bands are effectively related to the process of intentional motor switching.

Neural Activities in Intentional Motor Switching after Coordinating Bodily Motions in Pairs

The seminal dual coding theory by Paivio (1971) posited that non-verbal and verbal stimuli differ in their representational format, whereby the former activates a dual code while the latter only a single one. These differences in code have implications for tasks such as visual search. The current eye-tracking visual search study aims to re-evaluate this theoretical framework while examining the role played by semantic processing, that has never been looked at before. We followed the original design by Paivio and Begg (1974), with participants searching for a target, cued either as a word or as a picture, in an array of either words or pictures. The target could be either semantically related or unrelated to the other distractors. Corroborating original results, response times for correct trials were faster in pictorial arrays and substantially slower when a cued picture had to be found in a word array. Semantically unrelated targets were looked at faster, for longer, and leading to overall shorter search responses than semantically related targets. Critically, these effects driven by semantic relatedness were amplified when codes had to be converted (e.g., picture-to-word). Our findings refine our understanding of the role semantic processing plays in the representational format of words and pictures and the implications it carries for visual search.

Semantic Processing Modulates the Attentional Accessibility of Verbal and Nonverbal Search Targets

Studies examining the impact of Focussed attention meditation on mismatch negativity (MMN) have yielded inconsistent and conflicting results, emphasizing the necessity for well-powered studies examining different meditation styles to comprehend MMN modulation. Addressing methodological issues from previous research, the present study focuses on expertise in mantra meditation, akin to focused attention meditation, employing a sufficiently powered investigation with a novel intensity MMN paradigm. This paradigm introduces both louder and quieter deviants to discern whether Meditation-induced MMN effects signify higher-order cognitive processes or result from sensory adaptation. While the findings indicate a tendency of higher MMN in novices compared to experts, statistical significance was not achieved. The modest effect is attributed to enhanced attention skills in novices through consistent practice. The consistent unidirectional polarity shift in event-related potential (ERP) to both deviant stimuli types suggests that intensity-related MMN effects may not solely rely on loudness-dependent modulation of sensory components but could signify higher-order deviance detection. Results from eLORETA source localization are consistent with bilateral temporal and frontal cortex activity, which had lower amplitudes for the expert mantra meditator group compared with novices.

Influence of mantra meditation on intensity mismatch negativity

Our senses receive a continuous stream of complex information. According to Event Segmentation Theory (EST), we parse this information into meaningful events, allowing us to extract relevant information, remember it, and act upon it. Previous research has related these events to so-called ‘neural states’: temporally and regionally specific stable patterns of brain activity, which tend to coincide with events in the stimulus. Here we show that these neural states additionally align with stable features in a movie stimulus that are relevant to a specific brain region. This supports the idea that many brain areas across the cortex apply event segmentation in a hierarchical manner. Using intracranial measurements, we further investigate whether neural states are present at a much smaller timescale and how their characteristics correspond to EST. Our initial findings provide support for the idea that neural states could underlie the cognitive skill of event segmentation.

The neural basis of Event Segmentation Theory during naturalistic perception: stable neural activity patterns throughout the cortex

Speech production in aphasia is often described as “effortful”, though the consequences of consistent, high degrees of cognitive effort have not been explored. Using recent work on mental effort as a theoretical framework, the present study examined how effort-related fatigue produces decrements in performance in picture naming among participants with post-stroke aphasia. We analyzed three data sets from prior studies where participants completed a large picture naming test. Decreasing naming accuracy across trials was statistically significant in two of the three samples. There were also significant effects of practice (better performance on a second test administration), word frequency (better performance for more frequent words), and word length (better performance for shorter words). These results are the first concrete demonstration of fatigue affecting performance on a language task in post-stroke aphasia. They open a new avenue for research on mental effort/fatigue with potential implications for aphasia assessment, treatment, and management.
