invitation to a philosophy talk - reminder

by Krisztina Biber

The CEU Department of Philosophy cordially invites you to a talk by Aldo Frigerio (Catholic University, Milan) on 'Conditions of Reference' 5.30 PM, Tuesday, 2 October 2007, Zrinyi 14 building, Room 412 ABSTRACT According to Frege, in order to refer to an object we must grasp a conceptual content which uniquely identifies that object. Frege called it sense. Russell did not agree with Frege about this matter: he thought that grasping a conceptual content is not a sufficient condition in order to refer to an object. We can grasp a conceptual content that identifies an object and nonetheless not know which object that object is and not be able to recognize it among others. Referring requires a much stronger connection between the speaker and the object. This connection is acquaintance. Only if we know an object by acquaintance can we refer to it, because only in that case we know which object that object is and are able to recognize it among others. If we only know an object by description, the link between our words and the object is not reference but a weaker connection, which Russell called denotation. In this talk I would like to give some arguments in favor of Freges view. Particularly, I will show that Russells theory of reference produces too many ambiguities: every device of singular reference (proper names, indexicals and definite descriptions) can refer both to objects we are and to objects we are not acquainted with. If these devices had different meaning depending on the relation the speaker maintains with the referent, they would be systematically ambiguous. Another weakness of Russells view is the fact that according to it, in order to understand other people who refer to an object, we should be able to know if they are acquainted with their referent or not. But we often fail to have that information and this fact does not jeopardize our comprehension.

TITLE: Visual Prediction: Psychophysics and neurophysiology of compensation for time delays AUTHOR: Romi Nijhawan ABSTRACT: A necessary consequence of the nature of neural transmission systems is that as change in the physical state of a time-varying event takes place, delays produce error between the instantaneous registered state and the external state. Another source of delay is the transmission of internal motor commands to muscles and the inertia of the musculoskeletal system. How does the central nervous system compensate for these pervasive delays? Although it has been argued that delay compensation occurs late in the motor planning stages, even the earliest visual processes, like phototransduction contribute significantly to delays. I argue here that compensation is not an exclusive property of the motor system, but a pervasive feature of CNS organization. Although, the motor planning system may contain a highly flexible compensation mechanism, accounting not just for delays but also variability in delays (e.g. due to variations is luminance contrast, internal body temperature, muscle fatigue etc.), visual mechanisms also contribute to compensation. Previous suggestions of this notion of visual prediction led to a lively debate producing re-examination of previous arguments, new analyses, and review of experiments presented here. Understanding visual prediction will inform our theories of sensory processes, visual perception, and impact our notion of visual awareness.

TITLE: A study of the science of taste: On the origins and influence of core ideas AUTHOR: Robert P. Erickson ABSTRACT: Our understanding of the sense of taste is largely based on research designed and interpreted in terms of the traditional four basic tastes: sweet, sour, salty and bitter, and now a few more. This concept of basic tastes has no rational definition to test, and thus it has not been tested. As a demonstration, a preliminary attempt to test one common but arbitrary psychophysical definition of basic tastes is included in this paper; that the basic tastes are unique in being able to account for other tastes. This definition was falsified in that other stimuli do about as well as the basic words and stimuli. To the extent that this finding might show analogies with other studies of receptor, neural, and psychophysical phenomena, the validity of the century-long literature of the science of taste based on a few basics is called into question. The possible origins, meaning and influence of this concept are discussed. Tests of the model with control studies are suggested in all areas of taste related to basic tastes. As a stronger alternative to the basic tradition, the advantages of the across-fiber pattern model are discussed; it is based on a rational data-based hypothesis, and has survived attempts at falsification. Such population coding has found broad acceptance in many neural systems.

Erickson/A study of the science of taste: BBS Call for Commentaries

by Behavioral & Brain Sciences

Below is a link to the forthcoming BBS target article, "A study of the science of taste: On the origins and influence of core ideas" by Robert P.

To help us put together a balanced list of commentators, you must send us an indication of: 1) the relevant expertise you would bring to bear on the paper 2) which aspect of the paper you would anticipate commenting upon Please note that we only request expertise information in order to simplify the selection process. Commentators must be BBS Associates or suggested by a BBS Associate. To be considered as a commentator for this article, to suggest other appropriate commentators, or for information about how to become a BBS Associate, please reply by EMAIL as soon as possible: calls(a)bbsonline.org * Please respond to this Call no later than October 2, 2007 ===================================================================================== ===================================================================================== To help you decide whether you would be an appropriate commentator for this article, an unedited, uncorrected target article is retrievable at the URL that follows the abstract and keywords below.

Hence there is no need to reply except if you wish to comment, or to suggest someone to comment. If you are not a BBS Associate, please approach a current BBS Associate (there are currently over 10,000 worldwide) who is familiar with your work to nominate you. All past BBS authors, referees and commentators are eligible to become BBS Associates.
