[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.

[Koglist] [CEU Cogsci Talks] Nikhil Chaudhary (University of Cambridge), Thursday February 8, 4 pm: ``Hunter-Gatherer Social Organisation and Behaviour: Implications for Mental Health``

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] CCC Colloquium Monday, July 1, Fahd Yazin and Gargi Majumdar

by Ildiko Zsoka Varga

Dear All, The CEU Department of Cognitive Science and the Center for Cognitive Computation (CCC) invites you to the following two talks, both held on Monday, July 1. 1. Time: Monday, July 1, 10.00 Speaker: Fahd Yazin, University of Edinburgh Location: CEU Budapest site (1051 Budapest, Nádor u. 15.) N15. building, room 104. Zoom: Meeting ID: 941 3729 1638<https://ceu-edu.zoom.us/j/94137291638?pwd=FXMAybMTbPTewr4ZZHhvrAauvGz32l.1> Passcode: 337577 Title: Will to Predict: How models are created which create our world Abstract : Where do predictions come from in the brain? How do these predictions form and shape the models of the world we construct in our mind, driving our subjective experience? Known by various names across fields—mental models, situation models, cognitive maps— I explore the nature of these world models and predictions in sculpting our subjective experience using naturalistic stimuli. Next, I uncover the mechanisms by which these models are formed and deployed for inference using an unsupervised learning task of a probabilistic virtual world. I show how the Default-Mode Network (DMN) and specifically its Prefrontal sectors segment our environment into abstract, specialized domains - Spatial, Referential and Temporal - through a tripartite architecture, assembling top-down predictions tailored for each domain. This fragments subjective experience, which is unified globally through a multithreaded integration between its prefrontal and parietal core nodes. Computationally, the prefrontal cortex constructs these models by simulating internal data, adaptively adjusting it to match the external reality. Once built, humans compare low-dimensional summaries of these internal replicas to the external sensory information, amounting to rapid model selection. Formalizing the origin of top-down predictions as being computationally equivalent to predictive inference through Bayesian sampling, I discuss specifically how the prefrontal cortex discovers models and model parameters jointly from the data using internally synthesized data, and generally how the DMN utilizes these to form our subjective experience. ************************************************************************************* 2. Time: Monday, July 1., 15.00 Speaker: Gargi Majumdar, University of Hamburg Location: CEU Budapest site (1051 Budapest, Nádor u. 15.) N15. building, room 104. Zoom: Meeting ID: 958 1739 2309<https://ceu-edu.zoom.us/j/95817392309?pwd=mRqp5ZpV4vTJlXLLN8a8M9Os3U1BY2.1> Passcode: 454588 Title: Navigating the unknown in emotion dynamics Abstract: An enigmatic phenomenon of the mind that drives almost all our actions and has attracted scientists and sages in its quest for centuries is emotion. Divergent views on the definition of emotion combined with various psychological and computational models have populated the field of emotion research for a long time. Most of the proposed theoretical models are yet to be exploited empirically to robustly explain our affective experiences. Combining the theoretical tenets of the Bayesian Brain hypothesis and predictive coding, I aimed to investigate whether prediction uncertainty can robustly track the temporal dynamics of complex emotions, along with formulating insights into deviations or disruptions of the process. Accordingly, using behavioral and large-scale neuroimaging data, I show how optimal representation of uncertainty can drive the temporal dynamics of our emotions. Crucially, this uncertainty naturally emerges as a continuous, hierarchical inference from the fluctuating valence while watching a movie. Extending this framework further, I explored whether age-associated idiosyncratic changes in emotional processing can stem from misrepresentation and miscomputation uncertainty. Finally, I investigated the dynamic interplay between rest and emotion and how intermittent anticipatory or ruminative resting periods change our emotional experiences.

[Koglist] [CEU Cogsci Talks] Tobias Donner (Dept. of Neurophysiology & Pathophysiology, University Medical Center Hamburg-Eppendorf): Flexible Behavior through Adaptive Brain Network Dynamics. June 12, 2024, 4 pm, D001

by Gyorgyne Finta

The CEU Department of Cognitive Science and the Center for Cognitive Computation cordially invites you to the following talk by: Tobias H. Donner, Dept. of Neurophysiology & Pathophysiology, University Medical Center Hamburg-Eppendorf Date: Wednesday, June 12, 2024 Time: 4 pm (to 5:30 pm) CET Venue: D001 (QS Vienna) Chair: Jozsef Fiser Flexible Behavior through Adaptive Brain Network Dynamics Cognitive behavior rapidly adapts to changing environmental contexts. This flexibility distinguishes cognitive behavior from reflexes. I propose that this flexibility results from the rapid reconfiguration of distributed cortical networks that implement the transformations required by a given task and context. This reconfiguration is enabled by rapid plasticity mechanisms that are controlled by neuromodulators released from the brainstem. To support these claims, I will present human MEG and fMRI experiments, in which we systematically manipulate context variables, such as task rules or environmental volatility. We quantify the resulting changes in content-specific neural interactions (e.g., selective for sensory evidence or behavioral choice), across a large set of cortical regions. We relate these cortical interactions to the dynamics of (proxies of) brainstem modulatory activity. This approach reveals that the structure of cortical interactions changes in a context-dependent manner. These changes are predicted by brainstem modulatory activity, which, in turn, tracks hidden changes in the environment. Preliminary results indicate that the cognitive recruitment of modulatory brainstem systems is impaired in individuals with a high risk of developing psychosis. Our results open a new window on the dynamic brainstem sculpting of large-scale cortical networks for flexible cognitive behavior. I speculate that this sculpting goes awry in many mental disorders. *Anyone not affiliated with CEU wishing to attend in-person in Vienna must reply here<https://forms.office.com/e/0QfsXE7WHf> to get access to the lecture hall.

[Koglist] [CEU Cogsci Talks] CCC Colloquium - Mark Ho - Monday, June 10

by Ildiko Zsoka Varga

Dear All, The CEU Department of Cognitive Science and the Center for Cognitive Computation (CCC) invites you to the following online talk. *Please note that this is an online event only, next Monday, starting from 3 PM.* Speaker: Mark Ho (New York University) Title: How do people see, simplify, and solve problems? Abstract: Everyday life often gives us new problems to solve. For example, imagine flying back from a relaxing vacation and your return trip includes a layover in a new city. You’ve just landed at your connecting destination but learn that the next flight has been canceled. Suddenly, you need to start considering a whole new set of possibilities, constraints, and goals: When is the next flight? Would it be nice to stay a few days and explore? When do I have to be back at work? Could I take a car or train home instead? How long would that take? How much would it cost? Then, you would actually need to do something based on these considerations. Put another way, you need to come up with and then execute a novel plan. Our capacity to flexibly plan and act in new situations (such as deciding what to do when a connecting flight gets canceled) is both quotidian and remarkable. This is because planning is an exceptionally cognitively demanding process, and yet we are able to plan successfully despite having limited attention, memory, and time. No other species and no existing artificial intelligence system can plan as flexibly, generally, and efficiently as we do on a routine basis. What explains our ability to plan? To understand processes like planning, cognitive scientists often develop formal, mathematical models that capture general principles underlying how people think and act (similar to how Newton’s laws capture general principles underlying how physical objects interact). One of the earliest and most influential models of planning, proposed by Newell and Simon (1972), is based on the idea that people have a representation of a task (e.g., for chess, an understanding of how the pieces move and how to win) and then search for good actions to take using that representation (e.g., by simulating and evaluating different sequences of chess moves). Recently, we built on this original distinction between representing tasks and searching for actions by formulating a new theory of planning. Specifically, we propose that people not only search for good actions, but also search for good task representations via a process that we refer to as value-guided construal. Our account of value-guided construal allows us to pose two broad questions—one conceptual and one empirical. First, the conceptual question: What makes a task representation good? We propose that a task representation is good if it is simple and planning with it leads to a successful solution. Put another way, good task representations balance utility and complexity. Our computational model allows us to quantify this tradeoff for a given task. The second question is empirical: Do people form task representations that balance utility and complexity? Answering this question requires data, so we designed a task in which participants needed to plan how to navigate around obstacles in 2D mazes to reach a goal. We wanted to understand how they represented the mazes to plan, and so in a series of experiments, we assessed their memory of task elements after planning using post-trial questions as well as their thought process during planning using mouse tracking. Across these experiments, we found robust support for the idea that people trade off the utility and complexity of a task representation, as predicted by our account of value-guided construal. Our results tell us whether people flexibly form task representations that trade-off utility and complexity, but they also raise intriguing questions about how people might do so. The current work does not provide a definitive answer to such questions, but we explore how it might be done in principle. For example, one could start by solving the simplest construal and only add in new details (such as obstacles) as needed. Background knowledge about a domain could also guide which details to include in a construal—for instance, in chess, knowing that the queen is the strongest piece on the board might bias one to consider construals that include it. The human capacity to plan in novel situations is both familiar and puzzling, and understanding what makes it possible remains an important scientific challenge. The framework of value-guided construal provides a new perspective on this old question by drawing attention to the role that actively simplifying tasks plays in allowing people to more efficiently use limited cognitive resources. Our hope is that this work can serve as a starting point for further examination of the construal process itself, as well as other cognitive mechanisms that interface with planning.
