[koglist] Meghívó - BME Kognitív Szemináriumsorozat / Invitation - BME Cognitive Seminar Series

by Attila Keresztes

We cordially invite you to the next lecture of the BME Cognitive Seminar Series: Date & Time: October 29, Monday, 12:00-13:00 Location: BME, XI., Egry József utca 1., T. ép 515. *Sensory noise processing in the human brain: insights from object recognition studies on healthy and amblyopic subjects* *Bankó Éva* Information Technology Department, Pázmány Péter Catholic University Neurobionics Research Lab http://vision.itk.ppke.hu/ Personal webpage: http://digitus.itk.ppke.hu/~banko/ <http://digitus.itk.ppke.hu/%7Ebanko/> Abstract Human visual object recognition is fast and efficient when viewing conditions are good. However, under low visibility conditions the visual system must recruit additional processing resources to handle the noisy and deteriorated visual images, thus object recognition becomes more effortful. Even though this is often the case, little is known about the neural mechanisms engaged in processing of noisy images. This is even more important since adding noise to images is widely used in decision-making studies to modulate task difficulty while not taking into account the confound introduced by the increased sensory processing demands. In a series of experiments on healthy and amblyopic subjects we have pinned down both in time and space the active processes associated with sensory noise processing using faces with decreased phase-coherence. Namely, phase noise affects the electrophysiological responses in the first 300 ms following stimulus onset that is unrelated to changes in task-difficulty; most importantly, there is an increase in the ERP single-trial (i.e. true) response amplitudes between 200 - 300 ms after stimulus onset -- involving the P2 component -- the noise-modulation of which is diminished in amblyopia. This amblyopic deficit measured on the P2 component predicted the severity of the noise-related behavioral impairments and could not be explained by an overall increase in stimulus uncertainty or task difficulty in the case of noisy stimuli, which have been also proposed previously as explanations of the noise-related ERP changes. On the other hand, the noise-modulation of the N170 component of the ERP responses -- reflecting structural processing of face images -- was similarly affected by the presence of noise in the amblyopic and the fellow eye of amblyopes, suggesting that the noise-induced decrease of the N170 could simply be due to the decrease in the face content of the images. Furthermore, we also showed that processing of phase randomized as compared to intact faces is associated with increased fMRI responses in specific areas of the lateral occipital cortex. These results suggest that efficient processing of noisy images depends on the engagement of visual cortical mechanisms that take place after the early structural processing of visual objects has been completed and is reflected in the P2 component of the ERP response sand most likely localized to a retinotopic part of the lateral occipital cortex that has been implicated in grouping and image segmentation. -- Attila Keresztes Junior Research Fellow Budapest University of Technology and Economics Dept. of Cognitive Science, Egry József u. 1, Budapest 1111, Hungary Tel: +36 1 4633525

[koglist] [CDC Seminars] ANNOUNCEMENT: CDC Seminar, Liz Robinson, Wednesday, October 17, 5 PM

by Mikolaj Hernik

PLEASE NOTE: Our seminar room has a limited capacity. Please arrive early to ensure you get a seat. The talk will begin promptly at 5. The next talk in the CDC Seminar series will be given by: Liz Robinson, The University of Warwick Date: Wednesday, October 17, 2012, 5 PM Location: Cognitive Development Center, Hattyú u. 14, 3rd floor To Believe or Disbelieve what we’re Told? Understanding about Transfer of Knowledge Abstract: I shall contrast two different bases for judging whether or not an apparently well-intentioned informant’s testimony is likely to be reliable. In the first, the informant serves as a proxy for the self, gaining the knowledge that we would gain if we had that same experience. For example, our informant looks out the window and tells us that the taxi has arrived. Assuming the informant is well-intentioned, it is reasonable to believe that the taxi has indeed arrived. Under circumstances such as these we can make an accurate evaluation of the truth of what we are told, but we gain only specific knowledge. For gaining generalizable and culture-specific knowledge such as names or function of objects, we need to determine whether our informant has characteristics indicative of being generally knowledgeable, such as having a history of accuracy. Our prediction of trustworthiness will be rough and ready, and could just be based on rules of thumb rather than understanding of knowledge transfer. I shall summarize experiments examining children’s understanding that a person with a history of inaccuracy will not necessarily be unreliable in the future (their errors might be due to circumstances that no longer hold), while a person with a history of accuracy will not necessarily be reliable (they might have had external help that is no longer available). Taking such circumstances into account demands understanding of knowledge transfer.

[koglist] reminder: invitation to a talk on`Caring for Autonomy: Becoming Self-Governing With Others` Help` by John Christman - 16 October 5.30 PM

by Krisztina Biber

The CEU Department of Philosophy cordially invites you to a talk (as part of its Departmental Colloquium series) by John Christman (Penn State University) on `Caring for Autonomy: Becoming Self-Governing With Others` Help` Tuesday, 16 October, 2012, 5.30 PM, Zrinyi 14, Room 412 Working Abstract Respecting the autonomy of agents grounds various obligations to others such as non-interference, deference to her authority over self-regarding decisions, limitations on paternalism, and so on. According to a broadly liberal moral sensibility, respecting others? in this way implies accepting (in some sense) the values they autonomously hold even if they are judged problematic, immoral, self-destructive, or otherwise non-ideal. However, in discussions of such respect, it is generally assumed that persons expressing that respect (or not) have no direct bearing on whether the subject of that respect is herself autonomous. But in many situations, persons interact in a way that helps establish or re-establish the autonomy of one or both of these agents themselves. For example, the would-be paternalist may be a committed aid worker whose professional obligation is to facilitate the process of re-establishing autonomy for vulnerable victims of trauma. In such scenarios, the usual lines between hard and soft paternalism, as well as the standard liberal rejection of the former, do not apply. Still, it would be wrong for the aid worker to simply impose her views of a decent life on the struggling person. How, then, do we reformulate restrictions on paternalism and other such normative strictures grounded in respect for autonomy in scenarios where the relationship between client and aid worker is itself a crucial part of the process that results in the self-governing agency of the client? This paper explores these issues and argues that such (very typical) scenarios indicate that conceptions of autonomy must view the self as diachronic as well as socially constituted but also must be sensitive to the ways autonomy can be (re-)established only with others? help. In particular, the obligation to remain relatively neutral toward the content of others? values in showing respect for their autonomy (the broad liberal sensibility) must be reformulated to take into account the way interpersonal dynamics themselves help establish the autonomy with which persons hold the values that they hold. These observations are applied to cases of aid and care where such questions are central.

[koglist] reminder: invitation to a talk on"Belief and its bedfellows" by Tim Bayne - 9 October, 5.30 PM

by Krisztina Biber

The CEU Department of Philosophy cordially invites you to a talk (as part of its Departmental Colloquium series) by Tim Bayne (University of Oxford) on "Belief and its bedfellows" Tuesday, 9 October, 2012, 5.30 PM, Zrinyi 14, Room 412 ABSTRACT This paper attempts to draw some lessons about the nature of belief from considerations concerning beliefs’ ‘bedfellows’: states that are not paradigmatic beliefs but are belief-like in certain important respects. I examine the merits of various proposals about how to categorize such states, before turning to the question of what such states might be able to teach us concerning the nature of belief, the propositional attitudes, and mental states more generally.
