Sleep staging serves as the foundation for sleep assessment and disease diagnosis, constituting a crucial aspect of sleep research. The related work on automatic sleep staging has achieved numerous satisfactory outcomes. However, current research predominantly focuses on using sleep information as classification features, employing time-domain or frequency-domain measures as local features, using comprehensive brain network information across channels as global features, while overlooking the spontaneous regularities in brain activity. Simultaneously, brain microstates are considered closely linked to brain activity and can be used to investigate the regular variations in the overall brain potential. To explore the regular changes in the microstates of brain function during sleep stages based on electroencephalogram (EEG), especially the regular changes in sleep structure, we initially conduct microstate clustering on the EEG data during sleep, followed by characterizing the sleep structure of the participants based on these microstates. Subsequently, we integrate the sleep structure with traditional sleep information features and perform automatic sleep staging.Our experiments make the following contributions: (1) Being the first to introduce the use of sleep structure for automatic sleep staging. (2) When there are 7 or more than 7 microstate classes, the model performs well. (3) Proposing a sleep automatic staging model that integrates sleep structure and sleep information.

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

Theory of mind is an essential ability for complex social interaction and collaboration. Researchers in cognitive science and psychology have previously sought to integrate theory of mind capabilities into artificial intelligence (AI) agents to improve collaborative abilities (Cuzzolin, Morelli, Cirstea, & Sahakian, 2020). These approaches, however, are hampered by the need for labor-intensive hand-labeling of datasets, which prevents them from scaling up to large, real-world datasets. To address this challenge, we introduce the Recurrent Conditional Variational Autoencoder (RCVAE), a novel model designed to predict intent from human behavioral trajectories without the prerequisite of hand-labeled data. We show that in the Overcooked-AI environment, the RCVAE outperforms baseline Long Short-Term Memory (LSTM) models in predicting intent, achieving higher prediction accuracy and greater predictive stability. The implications of these results are significant; the RCVAE's proficiency in learning the relationship between basic actions and resulting contextual behaviors, without needing hand-labeled data, will be crucial for scaling from simple to complex, real-world environments.

Generative Artificial Intelligence for Behavioral Intent Prediction

Causal reasoning is a critical aspect of both human cognition and artificial intelligence (AI), playing a prominent role in understanding the relationships between events. Causal Bayesian Networks (CBNs) have been instrumental in modeling such relationships, using directed, acyclic links between nodes in a network to depict probabilistic associations between variables. Deviations from these graphical models’ edicts would result in biased judgments. This study explores one such bias in the causal judgments of humans and Large Language Models (LLMs) by examining two structures in CBNs: Canonical Chain (A→B→C) and Common Cause (A←B→C) networks. In these structures, once the intermediate variable (B) is known, the probability of the outcome (C) is normatively independent of the initial cause (A). However, studies have shown that humans often ignore this independence. We tested the mutually exclusive predictions of three theories that could account for this bias (N=300). Using hierarchical mixed-effect models, we found that humans tend to perceive causes in Chain structures as significantly stronger, providing support for only one of the hypotheses. This increase in perceived causal power might reflect a view of intermediate causes as more reflective of reliable mechanisms, which could in turn stem from our interactions with the world or the way we communicate causality to others. LLMs are primarily trained on language data. Therefore, examining whether they exhibit similar biases in causal reasoning can help us understand the origins of canonical Chain structures’ perceived causal power, while also shedding light on whether LLMs can abstract causal principles. To investigate this, we subjected three LLMs, GPT3.5-Turbo, GPT4, and Luminous Supreme Control to the same queries as our human subjects, adjusting a key ‘temperature’ hyperparameter. Our findings show that, particularly with higher temperatures (i.e., greater randomness), LLMs exhibit a similar boost in the perceived causal power of Chains, suggesting the bias is at least partly reflected in language use. Similar results across items suggest a degree of causal principle abstraction in the studied models. Implications for causal representation in humans and LLMs are discussed.

Chain Versus Common Cause: Biased Causal Strength Judgments in Humans and Large Language Models

Although predicting others' behavior is a fundamental capacity of the human mind, building this intuitive psychology into machines has remained a challenge. To advance this aim, we introduce the Animate Agent World Modeling Benchmark - featuring agents engaged in a diverse repertoire of behaviors, such as goal-directed interactions with objects and multi-agent interactions, all governed by realistic physics. Humans tend to predict the future based on expected events rather than simulating step-by-step. Thus, our benchmark includes a cognitively-inspired evaluation pipeline designed to assess whether the simulated trajectories of world models capture the correct sequences of events. To perform well, models need to leverage predictive cues from the observations in order to accurately simulate the goals of animate agents over long horizons. Although recent developments have incorporated world models into state of the art model-based reinforcement learning (RL) agents, we demonstrate that these models perform poorly in our evaluations. A hierarchical oracle model sets an upper bound for performance, suggesting that in order to excel, a model should scaffold their predictions with abstractions like goals that guide the simulation process towards relevant future events.

Animate Agent World Modeling Benchmark

Despite computational algorithms outperforming humans in certain tasks, algorithmic advice is less used than human advice (algorithm aversion). Thus, algorithmic advice should be designed to avoid algorithm aversion. However, few studies have discussed the use of advice with an interval (e.g., 60.0 ± 2.0 %), a common format in algorithmic advice. This study confirmed in two behavioral experiments (N = 200) that advice use differed across advisors and that different advisors have a mainly influence on the process by which judges decide whether to ignore advice. Therefore, this study proposed to individualize the advice presentation so that the advice would be such that decreases the rate of judges ignoring the advice. For individualization, we focused on the distance between the advice and the initial judgment, a significant factor in advice utilization. Another behavioral experiment (N = 100) confirmed that our proposed advice design overcomes differences among advisors.

Advice Design to Increase the Use of Advice with an Interval to Overcome Algorithm Aversion

The multimodal deep neural networks, represented by CLIP, have generated rich downstream applications owing to their excellent performance, thus making understanding the decision-making process of CLIP an essential research topic. Due to the complex structure and the massive pre-training data, it is often regarded as a black-box model that is too difficult to understand and interpret. Concept-based models map the black-box visual representations extracted by deep neural networks onto a set of human-understandable concepts and use the concepts to make predictions, enhancing the transparency of the decision-making process. However, these methods involve the datasets labeled with fine-grained attributes by expert knowledge, which incur high costs and introduce excessive human prior knowledge and bias. In this paper, we observe the long-tail distribution of concepts, based on which we propose a two-stage Concept Selection Model (CSM) to mine core concepts without introducing any human priors. The concept greedy rough selection algorithm is applied to extract head concepts, and then the concept mask fine selection method performs the extraction of core concepts. Experiments show that our approach achieves comparable performance to end-to-end black-box models, and human evaluation demonstrates that the concepts discovered by our method are interpretable and comprehensible for humans.

Understanding Multimodal Deep Neural Networks: A Concept Selection View

The advancement of intelligent systems requires the exploration of efficient computational architectures based on emerging electronic computing devices and the effective simulation of biomimetic functions to enhance overall intelligence. Here we design a memristor-based circuit inspired by self-awareness, which can realize bionic adaptive decision-making effectively and more intelligently through mimicking habituation learning mechanisms. Memristors serve as underlying units in the circuit supporting the simulation of functions akin to biological neurons and synapses. These contribute to the implementation of functionalities such as information filtering, integration, and synaptic plasticity with concise circuit structures and efficient computing way. Experimental results indicate that our circuit is capable of supporting rapid and efficient information processing through in-memory analog computing and making more reasonable and intelligent adaptive decisions by integrating biomimetic mechanisms. Extending this work to further research on large-scale decision-making systems holds promise for application in intelligent platforms, aiming to achieve advanced cognitive capabilities.

Memristor-based Bionic Decision-making Circuit Inspired by Self-awareness

The UN Security Council (UNSC) is entrusted with the responsibility of safeguarding global security. Analyzing the cognitive patterns from UNSC debates helps scholars gain insights into the intricacies of international relations and diplomatic discourse. In this study, our focus lies in the cognitive analysis of debates held within the UNSC. We employ metaphors and their associated concept mappings as a methodological tool to dissect the cognitive nuances present in the debates, spanning from January 1995 to December 2020. To undertake this extensive analysis from a large volume of documents, we leverage MetaPro, a state-of-the-art computational metaphor processing system to obtain the concept mappings of metaphors. We analyze cognitive variations by temporal and geographical variables. We also demonstrate the correlation between metaphor-reflected cognition and diplomatic behavior, and their recursive influence, based on large sample research. Our finding highlights the mutual impacts of metaphorical cognition and voting behavior at the UN.

Unveiling Diplomatic Narratives: Analyzing United Nations Security Council Debates Through Metaphorical Cognition

Perception Verbs (PVs) can have, besides their literal interpretation that 'X perceives Y', other interpretations depending on context. For example, in narratives we often find contexts where seeing something introduces a new referent, heralds a pivotal event, or compresses redundant information about characters' inner states. We computationally model the emergence of such pragmatic use in children (4-12y) with recent Language Models (LMs). Since LMs are partly trained on narrative corpora and can model coherence in narratives, we assume that a LM can infer whether using a PV is apt in contexts that humans can recognise as having a pragmatic function. We sample PV contexts from ChiSCor, a corpus of Dutch children's freely-told narratives, and use the confidence of LM predictions to identify developmental patterns in pragmatic use of PVs for children of different ages. Simultaneously, our setup allows us to identify types of pragmatic meaning that LMs still struggle with.

Modelling Pragmatic Inference in Children's Use of Perception Verbs with Language Models

Language models (LMs) have demonstrated remarkable proficiency in generating linguistically coherent text, sparking discussions about their relevance to understanding human language learnability. However, a significant gap exists between the training data for these models and the linguistic input a child receives. LMs are typically trained on data that is orders of magnitude larger and fundamentally different from child-directed speech (Warstadt & Bowman, 2022; Warstadt et al.,2023; Frank, 2023a). Addressing this discrepancy, our research focuses on training LMs on subsets of a single child’s linguistic input. Previously, Wang, Vong, Kim, and Lake (2023) found that LMs trained in this setting can form syntactic and semantic word clusters and develop sensitivity to certain linguistic phenomena, but they only considered LSTMs and simpler neural networks trained from just one single-child-directed dataset. We build upon previous research by conducting systematic tests on 5 datasets, comprising single and aggregated child data and a web corpus, using six different model architectures, including Transformers, to investigate whether the results of what is learnable from single-child input observed in previous studies are consistent across different model architectures and datasets. We find that models trained on three single-child datasets demonstrate consistent results, underscoring the robustness of forming meaningful syntactic and semantic representations from a subset of linguistic input specific to an individual child.

A systematic investigation of learnability from single child linguistic input

Humans tend to privilege an intermediate level of categorization, known as the basic level, when categorizing objects that exist in a conceptual hierarchy. Domain experts demonstrate a downward shift in their object categorization behaviour, recruiting subordinate levels in a conceptual hierarchy as readily as conventionally basic categories (Tanaka & Philibert, 2022; Tanaka & Taylor, 1991). Do large language models show similar behavioural changes when prompted to behave in an expert-like way? We test whether GPT-4 with Vision (GPT-4V, OpenAI, 2023a) demonstrates downward shifts using an object naming task and eliciting expert personas using the model’s system prompt. We find evidence of downward shifts when expert system prompts are used, suggesting that expert-like behaviour can be elicited from GPT-4V using prompting. We also find that there is an unpredicted upward shift in areas of non-expertise in some cases. These findings suggest that in the default case, GPT-4V is not a novice: instead, it behaves at default with a median level of expertise, while further expertise can be primed or forgotten through textual prompts. These results open the door for GPT-4V and similar models to be used as tools for studying differences in the behaviour of experts and novices even within the same large language model.
