The core argument examined posits that if the PCTT holds, there are physical processes whose outcomes cannot be predicted due to the uncomputability of the halting problem.The inability to predict certain computational processes, as claimed in the core argument, would make it impossible to consistently forecast or evaluate physical events, undermining the principles of empirical knowledge and the validity of scientific models. I critically analyze this core argument, which is based on three key suppositions: physicalism, the PCTT, and the uncomputability of the halting problem. It is shown through a counter-argument that these suppositions cannot hold simultaneously. We can demonstrate that when taking into account physical constraints and the meaningfulness of computations, the unpredictability posited by the core argument can be shown to be flawed and the claim of uncomputable physical decisions does not hold under closer empirical scrutiny. Nevertheless, it is also possible to show that a bounded, empirically constrained version of the core argument still holds, preserving some of the unpredictability under specific physical limitations. This offers a refined understanding of the limits of computability and prediction in physical systems. ______________________________ Seminar website (currently under construction): http://lps.elte.hu/lps The seminar is open to everyone, including students, visitors, and faculty members from all departments and institutes!

[Koglist] [CEU Cogsci Talks] CCC Colloquium: Dominik Straub, Tuesday, 8 October, 5 PM

by Ildiko Zsoka Varga

Dear All, The CEU Department of Cognitive Science and the Center for Cognitive Computation invites you to the following talk: Speaker: Dominik Straub<https://dominikstrb.github.io/> (TU Darmstadt) Title: Inverse optimal control for modeling continuous perception and action Abstract: Normative models of behavior strive to explain why behavior unfolds the way it does. These models have been highly successful in explaining many phenomena in neuroscience, cognitive science, and related fields. The power of these approaches derives from the combination of controlled experimental designs with their associated normative models, e.g. forced-choice psychophysics with Bayesian observer models. Unfortunately, these tasks do not have much in common with naturalistic behavior and require many trials with binary responses, often by highly trained participants. Continuous psychophysics is a recently developed experimental approach that abandons the rigid trial structure and replaces it with a more naturalistic and intuitive continuous tracking task. It produces more temporally fine-grained measurements and allow efficient data collection even with untrained participants. However, while highly controlled classical psychophysics tasks allow using normative models to estimate perceptual uncertainty, continuous tasks introduce additional cognitive and motor factors such as action variability, internal behavioral costs, and subjective internal models. In this talk, I will introduce a normative analysis framework based on Bayesian inverse optimal control that accounts for these factors. This approach enables estimating perceptual uncertainty, action variability, behavioral costs, and subjective beliefs about the task dynamics from behavior in a tracking task. I will then discuss the limitations of the method and show recent methodological extensions that address these limitations and allow applying inverse optimal control to a wider range of tasks including information-seeking behavior. In summary, these methods open up the possibility of fitting normative models to more naturalistic continuous behavior.

[Koglist] HUN-REN TTK KPI tudományos előadás, Claude Alain, Rotman Research Institute at Baycrest (Toronto,Canada), 2024. október 18. (péntek) 13:10, Speech-in-Noise Perception: The Interplay between Production and,Perception

by Gábor Háden

Kedves Kollégák! A következő HUN-REN TTK KPI tudományos előadást Professor Claude Alain, a Rotman Research Institute Baycrest (Toronto, Ontario) kutatója tartja. Előadásának címe és rövid leírása: Speech-in-Noise Perception: The Interplay between Production and Perception Speech perception and production are fundamental to human communication. Evidence suggests that speech perception and production systems interact, especially in challenging listening situations. In this presentation, I will summarize findings from several behavioural and neuroimaging studies suggesting that motor representations support speech perception under challenging listening conditions as a compensatory mechanism for resolving the signal. We showed: The engagement of the speech motor system during speech perception is context-dependent and context-independent.The observed brain activation occurred outside the core regions of the speech-motor system in sensorimotor and higher-level cognitive executive networks. The engagement of the speech motor system through syllable repetition facilitates speech-in-noise perception. The implications of these results are discussed in the context of current models of speech, and a new model is proposed that incorporates the auditory, cognitive and motor processes shared between perception and production.

[Koglist] Doctoral Candidate position in the alignAI project, iSearch lab at TU Munich

by Georgina Török

Dear all, The iSearch lab at the Technical University of Munich (TUM) is advertising an EU-funded doctoral position in the Marie Skłodowska-Curie Actions Doctoral Network project "alignAI". We are looking for a Doctoral Candidate to join our research group to work on a project tackling children's and adolescents’ preferences in the use of LLMs under the supervision of Prof. Azzurra Ruggeri. In addition to the primary focus of this doctoral project, we are open to exploring other relevant projects that align with our broader research interests, particularly in the areas of ecological active learning. The iSearch lab's research is dedicated to various facets of cognitive development and learning processes in children. We employ a multidisciplinary approach that integrates methods from psychology, education, and technology to understand and enhance children's learning experiences, in particular the active learning strategies that they employ in dynamically changing environments. The advertised doctoral position will be based in Munich, Germany, and will be funded for a duration of 36 months. The deadline for application is 4 November 2024. The position can be filled from early 2025. Please see the advertisement below for more details, and please share it with potentially interested parties. https://syncandshare.lrz.de/getlink/fiTygH9qCQQBYeuZv8Gc1m/Job%20Advertisem… Kind regards, Georgina Török Postdoctoral Researcher iSearch lab, Technical University of Munich

[Koglist] [CEU Cogsci Talks] REMINDER CDC Seminar: Moritz Köster (University of Regensburg), Wednesday, September 18, 4pm

by Anna Kispal

Dear all, The CEU Department of Cognitive Science invites you to the following talk: Moritz Köster<https://www.uni-regensburg.de/humanwissenschaften/entwicklungs-und-kognitio…> (University of Regensburg) Title: How infants learn about their physical and social world - a dynamic developmental systems approach Abstract: Human flexible adaptation relies on both individual learning mechanisms and the (culture-)specific learning environments we grow up in. With my research I aim to illuminate the ontogenetic foundations of this adaptation process in the infant years. I will report about infants’ neural mechanisms for the acquisition of basic physical concepts (such as object categories and physical events), focusing on the theta rhythm and predictive processing, and how these early developing concepts are shaped by social and cultural learning experiences, beginning in the first year of life. I will then further illustrate the interplay between infants’ cognitive capacities, and cultural influences in the development of early prosocial behavior and cultural learning. In summary, with a dynamic developmental systems approach, I aim to convey the origins of human flexible adaptation in early infancy, laying the ground for human cultural learning and the diversity of human development. Date: Wednesday, September 18, 2024 Time: 4 pm (to 5:30 pm) CET Venue: D001-Tiered* (QS Vienna) and Zoom (meeting ID: 969 2496 5784<https://ceu-edu.zoom.us/j/96924965784?pwd=c2duZ0dDMFdEMUthK2Mwa2wzMllEUT09>, passcode: 471712) Chair: Gergely Csibra *Anyone not affiliated with CEU wishing to attend in-person in Vienna must RSVP here<https://forms.office.com/e/UmqahBYTHg> to get access to the lecture hall.
