[Koglist] [CEU Cogsci Talks] REMINDER: Invitation to the Doctoral Defense of Jozsef Arato, Department of Cognitive Science, January 9, 10 am, October Hall

by Gyorgyne Finta

The Department of Cognitive Science cordially invites you to the public defense of the PhD thesis Active learning as a link between environmental statistics and the development of internal representations by József Arató PRIMARY SUPERVISOR: József Fiser SECONDARY SUPERVISOR: Gergely Csibra External Advisor: Constantin Rothkopf Members of the Dissertation Committee: Ernő Téglás, Chair, CEU Christopher Summerfield, external examiner, University of Oxford Richard Aslin, external examiner, Haskins Laboratories abstract | Although it is known that facing a dynamically changing sensory stream, people's perceptual decisions could be influenced not only by individual past stimuli, but also by extracted summary statistics of the stimuli, the effects of these long-term influences are underexplored. In the present thesis, I explored the impact of past stimulus statistics on two distinct types of visual decisions. In the first line of research, in Chapters 2-3, I focused on visual explorative decisions via eye-movements and investigated whether hidden statistical structures of complex scenes could influence visual exploration. I found that spatial regularities of visual stimuli influenced explorative eye-movement patterns, that this effect emerged over time, and it could predict the success in learning the underlying structure of the input. These findings suggest a strong relationship between visual exploration and learning, during which the two processes continuously influence each other. I also showed how this relationship depended on the explicit vs. implicit nature of the task. In the second line of research, in Chapters 4-5, I explored long-term statistical influences in perceptual decision making. To this end, I tested the influence of past probabilities of appearance on discrimination judgments about ambiguous stimuli. I found that statistics of past stimulus strongly influenced perceptual decisions independently of the well-documented short-term sequential effects. This past influence depended on the change-dynamics between long-term and recent stimulus probabilities, sometimes resulting in locally irrational biases. Taken together, the results in these two research domains are consistent with a framework, in which past stimulus statistics are perpetually and automatically built into complex internal representations, which in turn, depending on the task and type of regularity, can dramatically influence visual decisions. The defense will take place at October Hall, V. Budapest, Október 6 street 7, ground floor on Wednesday, January 9, at 10 am organized by the Department of Cognitive Science Györgyné Finta (Réka) Department Coordinator ~~~~~~~~~~~~~~~~~~~~~~~~ Central European University Department of Cognitive Science H-1051 Budapest Oktober 6 utca 7. tel: (36-1) 887-5138 fax: (36-1) 887-5010 http://www.ceu.edu http://cognitivescience.ceu.edu ______________________________________________ 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] CEU Departmental Colloquium, January 9: Ben Kenward (Oxford Brookes University) - Children's conceptions of norms and their attitudes to norm violations

by Denis Tatone

The CEU Department of Cognitive Science cordially invites you to its talk by: Dr. *Ben Kenward* (Oxford Brookes University) [web <https://www.brookes.ac.uk/templates/pages/staff.aspx?uid=p0078109>] Title: *Children's conceptions of norms and their attitudes to norm violations* Date: Wednesday, 09 January 2019 Time: 17:00-18:30 Location: Department of Cognitive Science, CEU, Oktober 6 st. 7, room 10 Abstract: This presentation will combine two approaches to understanding young children’s conceptions of normativity. Firstly, a theoretical argument integrating a large body of literature (including the well-established protest paradigm) will be advanced, suggesting that the earliest conceptions of what is right (normative) is not well-differentiated from what is intended. For philosophers, an almost insurmountable challenge has been to explain how what should be can be inferred from what is. For psychologists, the challenge is instead to explain why humans in fact routinely make that inference. This theory posits that the normativity concept arises from the interaction between phylogenetically ancient valence-based approach/avoid systems and more recent linguistic systems supporting talk about good and bad. The conflation between what is and what ought to be arises because of automatic connections between valence judgement and intention generation systems. Secondly this talk will focus on the presenter’s own program of empirical work examining children’s responses to moral norm violations, with the ultimate aim of discovering the proximate causes of children’s punishment motivation. Cross-cultural similarities will be demonstrated in young children’s tendencies to inflict punishment for norm violations. Unexpectedly, however, the most recent findings suggest that children punish without enjoying it, and their primary motivation is to deter norm violations, in contrast to the conclusions from much adult work suggesting that adults are primarily motivated by retribution. We are looking forward to see you.
