This research explores the potential of machine learning (ML) in identifying vocal markers for schizophrenia. While previous research showed that voice-based ML models can accurately predict schizophrenia diagnosis and symptoms, it is unclear to what extent such ML markers generalize to different clinical subpopulations and languages: the assessment of generalization performance is however crucial for testing their clinical applicability.
We systematically examined voice-based ML model performance on a large cross-linguistic dataset (3 languages: Danish, German, Chinese). Employing a rigorous pipeline to minimize overfitting, including cross-validated training sets and multilingual models, we assessed generalization on participants with schizophrenia and controls speaking the same or different languages. Model performance was comparable to state-of-the art findings (F1-score ~ 0.75) within the same language; however, models did not generalize well - showing a substantial decrease - when tested on new languages, and the performance of multilingual models was also generally low (F1-score ~ 0.50).

Most Chinese words are compounds formed through the combination of meaningful characters. Yet, due to compositional complexity, it is poorly understood how this compositional process would affect the access to the whole-word meaning. In the present study, we turned to the recent development in compositional distributional semantics (Marelli et al., 2017), and employed a deep neural network to learn the less-than-systematic relationship between the constituent characters and the compound words. Based on the composed representations as derived from the computational model, we quantified the extent to which the compound meaning can be predicted by nonlinearly combining the constituent meanings, i.e., the degree to which the characters could provide reliable information to access the compound meaning. We observed the effect of compositionality, as operationalized by the computed metrics, on compound recognition, over and above the effects of constituent character properties and compound properties. More importantly, we found that this effect was increasingly stronger when holistic access to the compound meaning became more challenging. These findings therefore, from a computational perspective, provided new evidence for the compositional process involved in Chinese word recognition, which also shed light on the universal process of compound comprehension.

Composition as nonlinear combination in semantic space: Exploring the effect of compositionality on Chinese compound recognition

People sometimes explicitly announce that they are being sarcastic. The announcement appears to be particularly common in text-based conversations where prosodic cues are more difficult to identify. In certain cases, the tone of a comment is sufficient to determine non-literal meaning. But what happens in the absence of these features, or when context forces us to explicitly caveat our sarcasm? In this study, we examine Reddit comments from \texttt{r/AskReddit} to see the features that are present in comments tagged with \say{/s}, a convention on the platform for users to denote sarcasm. We found that a host of cues which mimic prosody, and other aspects of figures of speech, were inconsistent predictors of announced sarcasm. In contrast, when talking about sociomoral topics such as politics or race, users were more likely to tag their comments with \say{/s}. This suggests that we are more likely to announce sarcasm in text-based conversations where misinterpretation would be detrimental.

Examining structural and semantic predictors of announced sarcasm on r/AskReddit

Extensive evidence from diverse areas of the cognitive sciences suggests that iconicity—the resemblance between form and its meaning—is pervasive and plays a pivotal role in the processing, memory, and evolution of human language. However, despite its acknowledged importance, iconicity in language models remains notably underexplored. This paper examines whether language models learn iconic associations between shape and sound, known as the bouba/kiki (or maluma/takete) effect, which has been widely observed in human language as well as English and multilingual vision-and-language models, including Finnish, Indonesian, Hungarian, and Lithuanian models in previous studies, using Japanese models. A comparison between the current results and the previous studies revealed that Japanese models learn language-specific aspects of iconicity, such as the associations between /p/ and roundness, and /ɡ/ and hardness, reflecting sound symbolic system in Japanese.

Spatial cognition and spatial language are a core site for diversity, both within and across language communities. For instance, when describing motion events, speakers through speech and gesture may anchor information either (egocentrically) to their body or (allocentrically) to geographical landmarks in the environment. Here we investigate whether the use of such egocentric versus allocentric frames of reference in co-speech gesture indeed depends on both bodily and environmental axes. In a real-world experiment, members from the traditionally allocentric Balinese community were shown small-scale motion events and asked to retell them. To evaluate the potential influence of both types of axes on gestural frame of reference use, in a 2x2 between-participant design they were assigned to conditions that contrasted the body-anchored axis the motion events unfolded on with the underlying geographical environment-anchored axis. It was observed that the type of body-anchored axis significantly predicted frame of reference representation in participants’ gestures, consistent with previous research. The type of environment-anchored axes, however, did not affect characteristics of participants’ gestures. These findings advance our understanding of the intricate interplay between language, space, culture, and environment.

Use of spatial reference frames for motion events in Balinese co-speech gesture

Children’s spatial and numerical skills are highly related, and predictive of concurrent and future mathematical ability (Lourenco et al., 2018). The number line estimation (NLE) task, in which children indicate the spatial positions of numbers on a line, is a commonly used index of spatial-numerical ability. Critically, training studies have demonstrated a causal link between NLE and math ability (Ramani & Siegler, 2008). Nonetheless, there is extensive debate about the role of numerical and domain-general abilities in the NLE task. Here, we used fMRI with young children to assess the neural mechanisms supporting NLE performance. Whole-brain and ROI analyses yielded significant activation in bilateral intraparietal sulcus (IPS) during the NLE task, relative to matched control conditions. Moreover, we found a positive association between neural maturity in bilateral IPS during the NLE task and behavioral measures of math ability (Cantlon & Li, 2013), controlling for analogical reasoning and spatial working memory.

Converging neural evidence for number-specific mechanisms supporting number line estimation

Success in competitive matches hinges on psychological and mental preparations, such as strategic decision and emotional control. Although relevant cognitive functions and corresponding neural activity have been reported in a simple short-term laboratory task, the contribution of neural activity to the outcome of a more complex and prolonged match-format task has not been examined. Therefore, we focused on esports players engaged in a fighting video game (FVG). We examined the association between electroencephalography results in the pre-round of FVGs and consequences of the rounds. The results showed that parietal beta and frontal alpha/gamma activities are associated with winning and losing, respectively, depending on the match’s situation. Furthermore, parietal beta activity exhibited approximately 80% accuracy in win-loss predictions using machine learning. Our findings suggest that the performance of skilled video game players is influenced by psychological and mental preparations with fluctuations in neural oscillations.

Best brain conditions for winning an esports competition: Electroencephalography amplitude in the frontal and parietal cortices associated with esports competition results

This study investigated what movements of skilled Latin American dancers make a good impression on audiences. Although there have been studies of skill development in dance movements and evaluations of the aesthetics of dance, there are no studies that have directly examined the relationship between dance movements and evaluations of those movements. We compared the Cuban Motion movements and their evaluations at different skill levels. The results show that: 1) heels and other body parts were coordinated in the R-L direction, 2) experts’ Cuban Motion’s hip trajectories were divided into symmetrical and asymmetrical groups, and 3) the symmetrical group was found to have higher Aesthetics and Dynamism factors, while the asymmetrical group had lower scores. These findings suggest that an experts Cuban Motion had the same body use in whole-body coordination, but the hip trajectory related to evaluation of Latin American dance divided into two directions for skill development.

Cognitive science has historically been introduced as a multidisciplinary field. Recent findings, however, suggest that psychology has come to disproportionately dominate cognitive science research publications. This study examines the degree of overlap between cognitive science and psychological science by comparing article keywords and author departmental affiliations extracted from flagship journals from each field over the past decade (2012-2022). The results reveal significant and consistent convergence, with over 50% of published authors stemming from psychology departments. The topics of study between the two remain similar as well. However, network analyses found fragmentation and a considerable focus by the community of cognitive scientists on modeling approaches that are absent in psychology at present. Based on the topics and socio-institutional analysis, we suggest that cognitive science is largely psychological science.

Sentence completion studies have shown that L1 English readers use verbal aspect (VA) as a cue to disambiguate pronouns in the context of sentences with transfer of possession verbs. Specifically, in the context of a sentence like “Mary gave/was giving a book to Bill”, a subsequent pronoun is more likely to refer to the source referent (“Mary”) when the aspect is imperfective (“was giving”) than when it is perfective (“gave”). L2 studies have shown mixed results on whether L2 speakers, living within an L2 country or outside, can utilise VA as a discourse cue. The current study tested L2 English speakers using an online Maze task, where a pronoun (“He” or “She”) referring to either the source or goal referent had to be chosen at the critical point in the sentence. The results showed that both L1 speakers and L2 speakers, regardless of location, used VA as a disambiguation cue.

The research focus on adaptivity in complex systems has propelled an exploration of diverse interactions characterized by state transition processes. However, the investigation of functional variances among processes, rooted in fundamental operands, remains insufficient. Recognizing this gap is crucial for unveiling the constituents of state transitions and their functional boundaries during ongoing adaptivity. To address this, our central focus is on quantifying the functional variance in the interactions of fundamental operands. This approach enables a systematic study of complex adaptive networks grounded in the dynamics of cognitive abilities, where elements adapt and evolve based on cognitive processes. To underscore this point, we emphasize translating ontologically irreducible networks into functionally representable ones at the meso-level, which is essential for assessing their effectiveness. Our active investigation during state transitions explores external interventions, aiming to shed light on mutual influences.
