Abstract

Identifying Amyotrophic Lateral Sclerosis (ALS) in its early stages is essential for establishing the beginning of treatment, enriching the outlook, and enhancing the overall well-being of those affected individuals. However, early diagnosis and detecting the disease's signs is not straightforward. A simpler and cheaper way arises by analyzing the patient's facial expressions through computational methods. When a patient with ALS engages in specific actions, e.g., opening their mouth, the movement of specific facial muscles differs from that observed in a healthy individual. This paper proposes Facial Point Graphs to learn information from the geometry of facial images to identify ALS automatically. The experimental outcomes in the Toronto Neuroface dataset show the proposed approach outperformed state-of-the-art results, fostering promising developments in the area., Comment: 7 pages and 7 figures

17. Perception-Action Coupling and the Dynamicist/Computationalist Divide

Author

Abstract

A common claim by advocates of embodied, dynamical approaches is that action and perception are “coupled.” On the face of it, this claim may not seem controversial, after all many researchers working in mainstream computationalist neuroscientific approaches also talk about the “coupling” of perception and action. Our goal here is to clarify the relation between these claims of perception-action coupling stemming from dynamical and from computational perspectives. Examining the empirical evidence that computationalists and dynamicists invoke to support their claims we conclude that, despite using similar terminology, they mean entirely different and incompatible things. Still, we propose that both approaches can, at least to some extent, accommodate the evidence invoked by the other. This suggests that the evidence should not, on its own, be used to argue in favor of one approach against the other, and that the disagreement is of a philosophical nature rather than an empirical one.

18. Reading Comprehension as Embodied Action: Exploratory Findings on Nonlinear Eye Movement Dynamics and Comprehension of Scientific Texts

Abstract

Reading comprehension is often conceptualized in terms of the internal processing of linguistic information and construction of accurate mental representations. In contrast, an ecological-enactive approach rejects this internalist focus and instead emphasizes the dynamic process of reader-text coupling in which eye movements play a constitutive role. In this study, we employed recurrence quantification analysis (RQA) to examine the relationship between reading comprehension and eye movement dynamics, based on eye-tracking data from the Potsdam Textbook Corpus recorded from beginners and experts reading scientific texts, followed by comprehension questionnaires. Moreover, we compared the findings from RQA to classical eye movement measures (number of fixations, mean fixation duration, regression fixation proportion). The results indicated that classical eye movement measures did not predict reading comprehension reliably, whereas recurrences in gaze steps were reliably associated with reading comprehension proficiency. Contrary to our original hypothesis, experts showed more irregular, rather than more regular, eye movement dynamics, and these were linked to more proficient reading comprehension. In line with previous research on naturalistic reading using nonlinear methods, the present findings suggest that reading comprehension is best understood as emerging from interaction-dominant coordination processes.

19. How WEIRD is Cognitive Science?

Abstract

Over the last decade, cognitive science and allied fields have been criticized for being excessively “WEIRD,” i.e., overly reliant on participants from Western, Educated, Industrialized, Rich, and Democratic societies. The lack of diversity among research participants is now widely acknowledged, but it’s a rather superficial problem, symptomatic of other more fundamental ones. This poster outlines what we see as four overlapping problems. Cognitive science is WEIRD not only in terms of who makes up its participant pool, but also in terms of its theoretical commitments (e.g., individualism and universalism), methodological assumptions (e.g., measurement and analysis methods), and institutional structures (e.g., funding and publishing). Merely solving the problem of WEIRD participants by sampling more widely is insufficient to address cognitive science’s more fundamental WEIRD theoretical, methodological and institutional problems. Coming to terms with this is necessary if we wish to make cognitive science relevant for all humanity.

Abstract

That cognition is embodied is a claim that virtually no cognitive scientist today will deny: after all, even the researcher who models cognition in terms of entirely abstract, “medium-independent” states and processes will concede that particular instances are always necessarily realized in some body (of some kind) or other. The same is true for the theme of this year’s CogSci meeting, “Cognition in Context”: even if you think that there are cases in which the context plays merely a peripheral role in cognitive processing, you cannot deny that cognition always occurs in some context or other. This symposium is motivated by the realization, on the one hand, that the concept of embodiment means different things to different researchers in different contexts (see, e.g., Wilson 2002; Wilson and Golonka 2013; Crippen and Schulkin 2020), just as, on the other hand, the concept of context means different things to different researchers with different views on body and mind (see, e.g., Clancey 1997; Mesquita, Barrett and Smith 2010; Ibáñez and García 2018).

Abstract

We collected individualized (unidentifiable) and aggregated openly available data from various sources related to suspected/confirmed SARS-CoV-2 infections, vaccinations, non-pharmaceutical government interventions, human mobility, and levels of population inequality in Brazil. In addition, a data structure allowing real-time data collection, curation, integration, and extract-transform-load processes for different objectives was developed. The granularity of this dataset (state- and municipality-wide) enables its application to individualized and ecological epidemiological studies, statistical, mathematical, and computational modeling, data visualization as well as the scientific dissemination of information on the COVID-19 pandemic in Brazil., Comment: 12 pages, 6 figures, 2 tables

37. Bayesian Dynamic Estimation of Mortality Schedules in Small Areas

Author

Subjects
Statistics - Methodology
Abstract

The determination of the shapes of mortality curves, the estimation and projection of mortality patterns over time, and the investigation of differences in mortality patterns across different small underdeveloped populations have received special attention in recent years. The challenges involved in this type of problems are the common sparsity and the unstable behavior of observed death counts in small areas (populations). These features impose many dificulties in the estimation of reasonable mortality schedules. In this chapter, we present a discussion about this problem and we introduce the use of relational Bayesian dynamic models for estimating and smoothing mortality schedules by age and sex. Preliminary results are presented, including a comparison with a methodology recently proposed in the literature. The analyzes are based on simulated data as well as mortality data observed in some Brazilian municipalities., Comment: 25 pages, 6 figures, 1 table
