[koglist] [CDC Seminars] CogSci CEU Departmental Colloquium: March 14. Can the comprehension of abstract language be rooted in sensory experiences?

by Gyorgyne Finta

The CEU Department of Cognitive Science cordially invites you to a talk (as part of its Departmental Colloquium series) by Anna Babarczy, Budapest University of Technology and Economics on Can the comprehension of abstract language be rooted in sensory experiences? Date: Wed, March 14, 2012 - 17:00 - 18:30 Location: Department of Cognitive Science, CEU, Frankel Leó út 30-34., Room G15 Can the comprehension of abstract language be rooted in sensory experiences? ABSTRACT: The question of learning the meaning of abstract language (roughly, expressions with no perceptible referents) has been bugging philosophers for thousands of years. More recently, a number of experimental paradigms have emerged trying to shed light on this issue. The basic idea explored in the talk is that people understand abstract (metaphorical) expressions by linking them to sensory or bodily experiences. If this is the case, we should be able to show that these experiences affect people’s interpretation of abstract utterances. The talk looks at the evidence we have so far (pro and contra).We're looking forward to see you there (Frankel Leo u. 30-34) ! _______________________________________________ Subscribe by sending an empty mail to seminars-subscribe(a)cdc.ceu.hu Unsubscribe by sending an empty mail to seminars-unsubscribe(a)cdc.ceu.hu

[koglist] elo"adás: Ladányi Eniko" (2013.06.27.) -- absztrakt (fwd)

by Kenesei Istvan

Ladányi Eniko" Konfliktusfeloldó mu"ködések a lexikai elo"hívás során 2013. június 27. 11:00 MTA Nyelvtudományi Intézet, Budapest VI., Benczur u. 33. www.nytud.mta.hu földszinti elo"adóterem Absztrakt Miközben szavakat hívunk elo" mentális lexikonunkból, az elo"hívandó szó reprezentációján kívül számos más szó reprezentációja is aktiválódik. Ha ilyenkor a célszó és a versengo" reprezentációk aktivációkülönbsége nem elég nagy, konfliktus jelentkezik e reprezentációk között, amit fel kell oldanunk ahhoz, hogy végül a megfelelo" szót produkáljuk. Egy újabb nézet szerint a nyelvi folyamatok során megjeleno" konfliktusok feloldásáért egy általános konfliktusfeloldó mu"ködés, a kognitív kontroll felelo"s. Ebbo"l a feltevésbo"l az is következik, hogy lehetséges, hogy specifikusan nyelvinek tartott tünetek megjelenéséhez valójában kognitív kontroll sérülések is vezethetnek. Elo"adásomban az elmélet felvázolása után egy olyan kutatásunkat fogom bemutatni, ahol specifikus nyelvfejlo"dési zavart mutató gyerekek kognitív kontroll és lexikai elo"hívási képességeit vizsgáltuk. Eredményeink szerint mind a lexikai elo"hívás, mind a kognitív kontroll sérült ezeknél a gyerekeknél, és a két tartományban nyújtott teljesítmény együttjárást mutat. Ez egyrészt arra utal, hogy specifikus nyelvfejlo"dési zavarban a nyelv kizárólagos sérülését hirdeto" korábbi elméletekkel szemben általánosabb képességek sérülése is feltételezheto", és részben ezek vezethetnek a nyelvi problémák megjelenéséhez is. Ezen túl eredményeink támogatják azt a nézetet, amely szerint a nyelvi folyamatok során megjeleno" konfliktusok feloldáshoz egy nem specifikusan nyelvi kognitív kontroll mu"ködés szükséges.

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 by given this week by: Juan-Carlos Gomez University of St Andrews Date: Wednesday, June 26, 2013, 5 PM Location: Cognitive Development Center, Hattyú u. 14, 3rd floor Title: Evolving joint attention: reference, expression, and intentionality Abstract: I will present a comparative approach to understanding Joint Attention skills in evolution and development as a key turning point in the emergence of communicative and mentalising skills in evolution. I will discuss examples of pointing, gaze following, and eye contact in apes, human infants, and persons with autism. I will argue that Joint Attention behaviours instantiate a type of mentalism (or intersubjectivity) characterized by the display and coding of referential expression. Referential expression is built on the coordination of intentional relations of two types: third-order (coding relation of other agents to objects), and second-order (coding relations of other agents to oneself). I will contrast these notions with the reductionist notions of behavioural rules and behavioral abstractions.

Theoretically, goal‑directed decisions have been characterized as involving computationally costly model inversion, for instance a tree search. Habits, on the other hand, have been thought to result from experience accumulated in lookup tables, summarizing past experience about state‑action pairs for efficient future re‑deployment without incurring further computational cost. While the former structure allows for fast adaptation, the latter relies on sampling the new consequences of behaviours in the world before it can change. However, theoretical work always suggested a softer distinction in a number of ways. First, efficient game playing algorithms replace subtrees with lookup table values to cut down on computational costs. Second, direct transfer of internal samples might shape habits without the need to rely on the costly experiential samples from the world. Finally, habits are typically characterised as one‑step state‑action pairs. But there is no strong theoretical reason to limit lookup tables to such simple structures. This opens up the possibility of directly transferring entire solutions to actor‑like habits. Here, we re‑analyse data from an explicitly goal‑directed tree‑search task and find evidence for generalization and re‑use of complex action sequences. We use this to analyse the process by which complex behaviours are stored for future re‑use, either arising through experience or as memorized solutions. This reveals richer habits and less sharp distinction between habits and goal‑directed choices.

Kedves Kollégák! Minden érdeklődőt szeretettel meghívunk az alábbi előadásra, amelyet a látórendszer élettanának és anatómiájának egyik világszerte elismert szakértője tart: Prof. Dr. Paul R. MARTIN, Save Sight Institute, University of Sydney, Sydney, Australia "Introduction to the non-standard visual system: results of anatomical and physiological studies in primates" Textbooks describe the visual process as a step-by-step re-construction of the visual world by the brain. The lecture describes experiments on subcortical visual pathways in primates which call this view into question. The data show that early stages of visual processing can inform the brain of complex features in the visual image. Időpont: 2013. július 9. (kedd), 13:00.

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 by given this week by: Giorgio Vallortigara Centre for Mind-Brain Sciences, University of Trento Date: TODAY, June 12, 2013, 5 PM Location: Cognitive Development Center, Hattyú u. 14, 3rd floor Title: Core knowledge of object, number and space: A comparative approach Abstract: Studies on the ontogenetic origins of human knowledge provide evidence for a small set of separable systems of core knowledge dealing with the representation of inanimate and animate objects, number and geometry. Because core knowledge systems are evolutionarily ancient, they can be investigated from a comparative perspective, making use of various animal models. In this review, I discuss evidence showing precocious abilities in non-human species to represent (i) objects that move partly or fully out of view, and their basic mechanical properties such as solidity, (ii) the cardinal and ordinal/sequential aspects of numerical cognition and rudimentary arithmetic with small numerousness, and (iii) the geometrical relationships among extended surfaces in the surrounding layout. Controlled rearing studies suggest that the abilities associated with core knowledge systems of objects, number and geometry are observed in animals in the absence (or with very reduced) experience, supporting a nativistic foundation of such cognitive mechanisms. Animal models also promise a fresh approach to the issue of the neurobiological and genetic mechanisms underlying the expression of core knowledge systems.
