We investigated the impact of linguistic cues and autistic traits on lie detection. Adult participants (N = 125) judged suspects’ statements in a detective game. Untruthful statements were marked by semantic leakage. Literature indicates that liars use fewer first-person pronouns and mental state terms. We manipulated the untruthful statements for the presence/absence of these cues to test their effect on lie detection. The adults were 89% accurate in detecting lies. Mental state terms did not affect accuracy, while presence of first-person pronouns hindered it. Having autistic traits did not influence lie detection. However, adults with higher autistic traits struggled to detect lies when these contained both a first-person pronoun and a mental state term. Post-hoc analysis showed that lie detection accuracy was lower for longer sentences. Our findings underscore semantic leakage&#39;s significance in lie detection, with nuanced effects of linguistic cues on accuracy, particularly for adults with higher autistic traits.

Semantic Leakage Enables Lie Detection, but First-Person Pronouns and Verbosity Can Get in the Way of Detection

EMNLP 2021 is planned to be a hybrid event in Punta Cana, Dominican Republic, with both on-site and fully virtual participation possible. The experience for on-site participants would closely approximate a normal pre-COVID *ACL conference, with 5-6 thematically organized parallel sessions and live Q/A and interactive discussion immediately after the talks. Presentations by virtual participants will be equitably interleaved with those of on-site participants, projected on the auditorium screens as if on-site, and also followed immediately by live Q/A and interactive discussion at a time during reasonable waking hours for the virtual presenter. For all participants, on-site and virtual, who are unable to attend a session due to either time-zone issues or because they are participating in another session live, talk recordings and slides will be available online at a minimum after the live presentation (and in many cases before as well), and questions may be submitted in advance on session-specific discussion boards and answered live in session with the usual visual aids if desired.

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

From daily newsfeeds to scientific papers, we often read the same text more than once. How do our eye movements in repeated reading differ from first reading? In this work we examine this question at scale with L1 readers of English via standard eye movement measures and their sensitivity to linguistic word properties. We analyze consecutive and non-consecutive repeated reading, and further compare ordinary and information-seeking reading. We find sharp and robust facilitation effects that can be modulated by the reading regime, the presence of intervening textual material, and the relevance of the information to the task across the two readings. Finally, we examine individual differences in repeated reading effects and find that their magnitude interacts with reading speed, but not with reading proficiency. Our work extends prior findings on multiple axes, providing a detailed empirical picture of repeated reading which could inform future models of eye movements in reading.

Déjà Vu: Eye Movements in Repeated Reading

Working Memory (WM) is a necessary component for models of human cognition and human-inspired robot cognitive architectures. Different theories explain how the limited capacity of WM should be maintained, including theories of forgetting through decay and interference. Yet, it is unclear how WM models informed by these theories might be used to inform robot cognition, and how they might shape robots' ability to engage in natural, situated, language-based interactions. To resolve this tension, we implemented an entity-level, feature-based WM system integrated into a robot cognitive architecture, which can be configured to reflect both decay- and interference-based dynamics. We demonstrate with a set of case studies how different parameterizations of these WM strategies have fundamentally different error modes in different interaction contexts. We formulate rules that inform the selection of decay and interference parameters to be used in contexts with different factors that are important for language-based interaction.

Uncovering the Rules of Entity-Level Robotic Working Memory

The CONTROL IS UP metaphor is an embodied cognitive mechanism that helps western speakers reason about power relations in terms of vertical spatial organization, This paper explores its multimodal elaboration in visual manifestations of pyramidal structured arrangements and kinetic practices such as genuflexion in medieval miniatures in order to (i) demonstrate the role of multimodal representations of metaphors in reasoning, (ii) unveil power relationships between different societal strata.
34 miniatures (12th ct. Liber feudorum maior) were analised with the “multimodal genuflexion test” to describe and measure (CAD-software) distances between kinetic elements (facial/manual gestures, postures).
Results indicate that (i) power relations are not just vertically represented (kneeling & bowing), physical distance between characters and position of hands are crucial, (ii) there is a significant positive correlation [U = 61,119; p = 0.003] between the power figure and the degree of “body bending” (bowing, kneeling) and hand distance.

Kinetic elements in genuflexion correlate with the degree of power relations in societal strata: The CONTROL IS UP metaphor in medieval miniatures

Humans have an intuitive understanding of music. We can predict the ensuing notes of a melody given the first few notes, but what exactly drives these predictions? Previous research on musical cognition explores probabilistic models of melody perception where a melody’s structure can be inferred given its surface. Other research theorizes about “musical forces”, forces that are analogous to how we represent the physical world, and which inform the way we form expectations about music. We propose a single model of melodic expectation that combines both ideas using a structured generative model and sequential Monte Carlo inference. The generative model formalizes these musical forces, and combined with inference, enables predicting the last note of a melody given the beginning notes. This model explains human performance in an existing dataset of melodic predictions. The model explains more variance than its ablations, and suggests an “intuitive physics” basis for melodic expectation.

An Intuitive Physics Approach to Modeling Melodic Expectation

How do humans infer the structural interpretations of a piece of music from its basic elements? Since recursive elaboration is an important structural principle in several musical traditions, generative probabilistic models are a useful tool for characterizing musical interpretation as a probabilistic inference problem. However, due to the high degree of ambiguity and combinatorial complexity of even short excerpts of music, exact inference (e.g. finding the "best" structural interpretation of a piece) is usually not feasible. The present work proposes a hybrid approach to this problem. An explicit and interpretable probabilistic top-down model is complemented with a heuristic parser that reverses the generative process in a greedy fashion and adapts to feedback from the top-down model via deep reinforcement learning. The combination of these two models bridges the gap between explicit but slow top-down knowledge and immediate musical intuitions on various levels of musicianship.

Inferring Musical Structure - A Hybrid Approach Combining Probabilistic Models and Reinforcement Learning

When completing a task for a prolonged period, our ability to sustain attention fluctuates over time. Accordingly, in mice, disengaged behaviour has temporal autocorrelation (i.e., ‘disengagement states’), with lapses clustering in time, rather than occurring randomly. In this disengaged state, mice make more errors and provide responses biased towards one side. What neural and physiological processes trigger the transition into, and out of, disengagement states? Here, we investigated the role of pupil-linked arousal. We used a public dataset of 140 mice performing a perceptual decision-making task, including extracellular recordings alongside behavioural and pupil responses. We applied hidden Markov models to identify engagement states based on response times. Preliminary results show that disengaged trials are associated with larger and more variable baseline pupil, and suggest that pupil size changes precede state transitions. These findings will provide a starting point for exploring the cortical, subcortical and neuromodulatory processes preceding task (dis)engagement.

Pupil dynamics preceding switches in task engagement

Pupil dilation has been associated with increased mental effort, which can be modulated by external sensory stimulation as well as internal cognition. Underlying a cognitive task are multiple cognitive processes which can be stimulus-driven, goal-driven or spontaneous. However, what remains unknown is how these processes correlate with pupil size modulations and whether it is possible to dissociate their individual effects. To answer this, we employed behavioral and pupil data from two cognitive tasks performed in internal and external attention conditions, where stimulus-driven attention demands were manipulated for the same set of tasks. Using model-based analysis, we were able to dissociate within conditions, how individual processes affect pupil and also compare their effects between conditions. We made two important and novel findings – first, for each condition we were able to dissociate stimulus-driven and goal-driven effects. Second, when compared between conditions, we found distinct stimulus-driven attention-based effects but similar goal-directed task-based effects.

How pupil tracks cognitive processes underlying internally- and externally-directed attention tasks

A behavioural and two EEG hyper-scanning experiments are presented which investigate how predictive processing modulates the way interlocutors align behaviourally and at the level of the brain (Hasson, 2012; Pickering & Garrod, 2007). In the experiments interlocutors engaged in dyadic interactions performing a semi-controlled semantic association game and where the p predictability of the semantic associations was manipulated. The behavioural results showed that both interlocutors were around 400 ms faster in the predictable versus non-predictable conditions The results of the two EEG studies aim at demonstrating (1) whether we observe brain-to-brain synchronisation between the interlocutors at the level of word semantics, and (2) whether prediction enhances this synchronisation. To our knowledge, this is the first study to directly demonstrate prediction effects in an interaction.

Does prediction drive neural alignment in conversation?

The brain uses contextual information and prior knowledge to predict future content during
language comprehension. Previously, it has been demonstrated that contextual word
embeddings, derived from Large Language Models, can be linearly mapped onto brain data. Recently, Goldstein et al. (2022) have used this method to study neural signatures of
predictive processing. They found that predictive signatures of an upcoming word can be
observed in its pre-onset signal, measured with ECoG during listening to naturalistic
narratives . In the fMRI domain, Caucheteux et al. (2023) have shown that including
embeddings of multiple upcoming words improves the model’s fit to brain data. This has
been interpreted as an indica4on that the brain encodes long-range predictions. In this study we examine whether the same predictive information can be found in MEG data, a signal with lower signal-to-noise ratio than EcOG and higher temporal resolution than fMRI. We show that: 1) The signatures of pre-onset predictions about the upcoming word are also detectable in MEG data similarly to ECoG and 2) Contrary to what has been observed in the fMRI data, including future embeddings does not improve brain encoding in MEG signals. These findings provide a novel avenue for studying predictive processing during language comprehension with naturalistic stimuli using MEG signals.

What MEG can tell us about predictive processing during language comprehension

Studies have reported that prestimulus brain oscillations guide perceptual experiences during AV speech perception. However, 'what' features in such oscillations drive perception remains unknown. In this EEG study (n=18), we investigated how prestimulus periodic oscillations and aperiodic components influence the perception of the McGurk illusion on a trial-by-trial basis. Using logistic mixed-effect models, we determined the topology of spectral markers that predict the brain response to illusory perception. We found lower levels of alpha (8-12 Hz) and beta (15-30 Hz) band oscillations over parieto-occipital sensors, lower aperiodic offset values over parietal-temporal sensors, and a lower global effect of exponent over the scalp that predicted the response to McGurk illusion. We conclude that the predominant source of variations in the prestimulus oscillatory state is manifested by aperiodic background activity and that variations in these oscillations and aperiodic activity, account for inter-trial and inter-individual variability in perception of the McGurk illusion.
