[Koglist] [CEU Cogsci Talks] Pascal Mamassian (CNRS & Ecole Normale Supérieure, Paris), Wednesday February 14, 4 pm: ``Measurements of perceived time of visual events``

by Gyorgyne Finta

The CEU Department of Cognitive Science cordially invites you to the following talk by: Pascal Mamassian<https://lsp.dec.ens.fr/en/member/647/pascal-mamassian>, CNRS & Ecole Normale Supérieure, Paris, France Date: Wednesday, February 14, 2024 Time: 4 pm (to 5:30 pm) CET Venue: D001 (QS Vienna) and Zoom: https://ceu-edu.zoom.us/j/99828555100?pwd=S2Y4VnRMTEFHMitWeWk4bnB0SGdXQT09<https://www.google.com/url?q=https://ceu-edu.zoom.us/j/99828555100?pwd%3DS2…> Meeting ID: 998 2855 5100 Passcode: 393080 Chair: Jozsef Fiser Title: Measurements of perceived time of visual events Abstract: Visual perception is not instantaneous. It takes a few milliseconds for light to be transduced in photoreceptors and tens of milliseconds more for neuronal spikes to occur at successive levels of the visual hierarchy. These delays necessarily impact our abiity to perceive time. I will present examples of human time perception from two classes of tasks, duration estimation and perceived time of an event. In duration estimation, we have shown that observers are able to estimate the duration of an interval even when the onset of that interval is not explictly provided. In perceived time, we have shown that the perceived time of an event is influenced by other events in their temporal proximity, and that this perceived time varies across the visual field. A better understanding of our sensitivity to and biases in the perception of time is important to fully appreciate how well we understand our sensory environment. *Anyone not affiliated with CEU wishing to attend in-person in Vienna must reply here<https://forms.office.com/e/HjaP91n2ep> to get access to the lecture hall.

by Gyorgyne Finta

The CEU Department of Cognitive Science cordially invites you to the following talk by: Nikhil Chaudhary<https://www.nikhilchaudhary.co.uk/>, Evolutionary Anthropologist based at the University of Cambridge Date: Thursday, February 8, 2024 (mind the unusual day please) Time: 4 pm (to 5:30 pm) CET Venue: D318 (QS Vienna) and Zoom: https://ceu-edu.zoom.us/j/94486731045?pwd=VCt1WGZnd1F0MkZleGYvaDRpWEg3Zz09<https://www.google.com/url?q=https://ceu-edu.zoom.us/j/94486731045?pwd%3DVC…> Meeting ID: 944 8673 1045 Passcode: 328579 Chair: Christophe Heintz and Angarika Deb Title: Hunter-Gatherer Social Organisation and Behaviour: Implications for Mental Health Humans lived as hunter-gatherers for the vast majority of our species' history. Therefore, research with contemporary hunter-gatherer societies can offer insight into the evolution of our psychology and physiology. Drawing on my fieldwork with BaYaka hunter-gatherers from Congo, I will discuss the selection pressures that have shaped human social cognition and behaviour. I will focus on the communal living arrangements, egalitarian social organisation, and extensive cooperation, particularly in the domain of childrearing, which are normative across contemporary hunter-gatherer populations. I will also discuss how deviations from these features of sociality, which are commonplace in high-income industrialised societies, may increase our vulnerability to mental health disorders due to evolutionary mismatch-when an organism faces conditions that differ from those that some trait of the organism is adapted to, resulting in pathology or maladaptation. *Anyone not affiliated with CEU wishing to attend in-person in Vienna must RSVP here<https://forms.office.com/e/jbHch9J0Am> to get access to the lecture hall.

[Koglist] [CEU Cogsci Talks] Online CDC Seminar: Alon Hafri (University of Delaware), 4 pm on Wednesday March 27

by Salih Bartug Celik

Dear all, The CEU Department of Cognitive Science invites you to the following talk: Alon Hafri, University of Delaware Title: Where language and vision meet: Shared representational principles and content Abstract: There are few domains as central to cognitive science as language and visual perception. They are typically studied in isolation, yet at some level, they must connect. How? My talk will explore this connection. First, I reveal surprising parallels in how language and vision encode information: Vision, like language, can be compositional. I explore the psychophysics of visual scene composition, finding that the mind builds relational representations (e.g., a vase on a table) in a canonical order. Next, I show that language and vision tap into the same modality-neutral conceptual representations. Using symmetry as a case study, I find a striking correspondence between linguistic and perceptual judgments of the same visual displays. Lastly, I demonstrate how language can offer a window into non-linguistic visuospatial representations, leveraging the unique ways that certain languages encode such properties, particularly Mandarin Chinese. By examining how Mandarin speakers describe novel objects ("daxes") in different visual contexts, I uncover an unexplored influence of spatial relations (a dax in a bowl) on object shape computations. Taken together, my work highlights the representational principles and content shared by language and vision, with implications for how infants acquire language from visual observation. Date: Wednesday, May 9, 2024 Time: 4 pm (to 5:30 pm) CET Venue: Online, Zoom meeting 969 2496 5784<https://ceu-edu.zoom.us/j/96924965784?pwd=c2duZ0dDMFdEMUthK2Mwa2wzMllEUT09> (passcode: 471712) Chair: Gergely Csibra Best, Bartu ______________________________________________ Subscribe by sending an empty mail to talks-subscribe(a)cogsci.ceu.edu Unsubscribe by sending an empty mail to talks-unsubscribe(a)cogsci.ceu.edu

[Koglist] [CEU Cogsci Talks] CCC Colloquium (Budapest) Ádám Gosztolai, March 20, 5:00 PM

by Ildiko Zsoka Varga

Dear All, The CEU Department of Cognitive Science and the Center for Cognitive Computation (CCC) invites you to the following talk. *Please note that this event will be held at CEU Budapest site (N13. building), from 5 PM.* Speaker: Ádám Gosztolai (EPFL) Title: Interpretable representations of neural dynamics using geometric deep learning https://arxiv.org/abs/2304.03376 Abstract: It is increasingly recognised that computations in the brain and artificial neural networks can be understood as outputs of a high-dimensional dynamical system conformed by the activity of large neural populations. Yet revealing the structure of the underpinning latent dynamical processes from data and interpreting their relevance in computational tasks remains a fundamental challenge. A prominent line of research has observed that task-relevant neural activity often takes place on low-dimensional smooth subspaces of the state space called neural manifolds. However, there is a lack of theoretical frameworks for the unsupervised representation of neural dynamics that are interpretable based on behavioural variables, comparable across systems, and decodable to behaviour with high accuracy. To address these challenges, we introduce Manifold Representation Basis Learning (MARBLE), a fully unsupervised representation-learning framework for non-linear dynamical systems. Our approach combines empirical dynamical modelling and geometric deep learning to transform neural activations during a set of trials into statistical distributions of local flow fields (LFFs). Our central insight is that LFFs vary continuously over the neural manifold, allowing for unsupervised learning, and are preserved under different manifold embeddings, allowing the comparison of neural computations across networks and animals. We show that MARBLE offers a well-defined similarity metric between different neural systems that is expressive enough to compare computations and detect fine-grained changes in dynamics due to task variables, e.g., decision thresholds and gain modulation. Being unsupervised, MARBLE is uniquely suited to biological discovery. Indeed, we show that it discovers more interpretable neural representations in several motor, navigation and cognitive tasks than generative models such as LFADS or (semi-)supervised models such as CEBRA. Intriguingly, this interpretability implies significantly higher decoding performance than state-of-the-art. Our results suggest that using the manifold structure yields a new class of algorithms with higher performance and the ability to assimilate data across experiments.

[Koglist] [CEU Cogsci Talks] Budapest Computational Neuroscience Forum - March 13.

by Ildiko Zsoka Varga

Dear All, The CEU Department of Cognitive Science and the Center for Cognitive Computation (CCC) invites you to the upcoming event of the Budapest Computational Neuroscience Forum<https://ccc.ceu.edu/budapest-computational-neuroscience-forum>. Speaker: Nikola Milićević, Pennsylvania State University Title: Sensory systems and combinatorial neural codes Abstract: Neural activity in sensory areas of the brain is shaped both by the stimulus and by the internal neural dynamics. When the stimulus space is known we can compute receptive fields of neurons. Receptive fields of individual neurons are convex in a number of brain regions (such as the hippocampus, and the visual cortex). The combinatorial neural code are the subsets of co-active neurons for some input to the neural network. Not any combinatorial code is compatible with convex receptive fields. This raises a natural question: how do recurrent networks produce convex codes? Towards this end, we study a recurrent neural network with the Dale’s law architecture. We describe the combinatorics of equilibria and steady states of neurons in threshold-linear networks that satisfy Dale's law. The combinatorial code of a Dale network is characterized in terms of two conditions: (i) a condition on the network connectivity graph, and (ii) a spectral condition on the synaptic matrix. In the weak synaptic coupling regime, the combinatorial code depends only on the connectivity graph, and not on the synaptic strengths. Moreover, we prove that the combinatorial code of a weakly coupled network is a sublattice, and we provide a learning rule for encoding a sublattice in a weakly coupled excitatory network. Surprisingly, we find that the architecture of a Dale network “enforces” convex code output, in both strong and weak coupling regimes. Finally, we introduce a method inspired by game theory for inferring receptive fields, when the stimulus space is unknown or at least no consensus has been reached as in the case of olfactory systems. Time: 17:00, Wednesday, 13 March, 2024. Location: CEU Budapest (1051 Budapest, Nádor u. 15.) N15. room 104.

[Koglist] [CEU Cogsci Talks] CDC Seminar: Jean-Remy Hochmann (ISC Marc Jeannerod), Wednesday, March 13, 4pm

by Salih Bartug Celik

Dear all, The CEU Department of Cognitive Science invites you to the following talk: Jean-Remy Hochmann (ISC Marc Jeannerod) Title: Incomplete Language of Thought in infancy Abstract: The view that infants possess a full-fledged propositional Language of Thought (LoT) is appealing, providing a unifying account for infants’ precocious reasoning skills in several domains. In this talk, I'll present evidence that preverbal infants possess structured mental representations, with abstract generalizable content. However, I'll argue that careful appraisal of empirical evidence suggests that infants lack a crucial component of a propositional LoT: discrete representations of abstract relations. Date: Wednesday, March 13, 2024 Time: 4 pm (to 5:30 pm) CET Venue: D002* (QS Vienna) and Zoom (meeting ID: 969 2496 5784<https://ceu-edu.zoom.us/j/96924965784?pwd=c2duZ0dDMFdEMUthK2Mwa2wzMllEUT09>, passcode: 471712) Chair: Erno Teglas If you want to schedule a meeting with Jean-Remy, please indicate your availability here<https://doodle.com/meeting/participate/id/dN7vMApe>!

[Koglist] [CEU Cogsci Talks] CDC Seminar: Manuel Bohn (Max Plank Institute/Leuphana University Lüneburg), Wednesday March 6, 4 pm

by Salih Bartug Celik

Dear all, The CEU Department of Cognitive Science invites you to the following talk: Manuel Bohn (Max Plank Institute/Leuphana University Lüneburg) Grounding socio-communicative development in everyday experience: an individual differences perspective Social cognition and communication are defining aspects of what it means to be human. In this talk, I want to present our research program that studies the driving forces behind socio-communicative development. Our goal is to understand how everyday social interactions influence development. To get there, we will have to overcome numerous theoretical and methodological hurdles. I will present the steps we have taken in recent years towards this goal, which include computational models of the cognitive processes underlying aspects of socio-communicative development, tasks to measure cognitive abilities on an individual level, methods to capture and quantify everyday experiences and international collaborations to probe the generalisability of findings. Much of our work is still in the early phases, so I am very much looking forward to feedback.
