3 studies investigated whether young children understand that the acquisition of certain types of knowledge depends on the modality of the sensory experience involved. 3-, 4-, and 5-year-old children were exposed to pairs of objects that either looked the same but felt different, or that felt the same but looked different. In Study 1, 36 children were asked to state, when one of these objects w...

We study the effects of allocative and informational externalities in (multi-object) auctions and related mechanisms. Such externalities naturally arise in models that embed auctions in larger economic contexts. In particular, they appear when there is downstream interaction among bidders after the auction has closed. The endogeneity of valuations is the main driving force behind many new, spec...

In sensory substitution, the user may be directly aware of distal objects, as in everyday perception, or make explicit cognitive inferences based on an awareness of the proximal stimulation. Anecdotal evidence supports the experience of distal attribution, but so far there have been few rigorous experimental tests of the claim. In this study, blindfolded participants observed a target light usi...

John Dilworth Western Michigan University The outlines of a novel, fully naturalistic theory of perception are provided, that can explain perception of an object X by organism Z in terms of reflexive causality. On the reflexive view proposed, organism Z perceives object or property X just in case X causes Z to acquire causal dispositions reflexively directed back upon X itself. This broadly fun...

Dynamic vision requires both stability of the current perceptual representation and sensitivity to the accumulation of sensory evidence over time. Here we study the electrophysiological signatures of this intricate balance between temporal segregation and integration in vision. Within a forward masking paradigm with short and long stimulus onset asynchronies (SOA), we manipulated the temporal o...

A recent study (Van Gelder et al., 2011) scrutinized the effects of providing people with information about suspended sentences on their opinions of these sentences, and concluded that the impact is modest or even absent. Re-analyzing the original data, we demonstrate that this conclusion greatly underestimates the relevance of informational provision. Recognizing that information is framed dif...

Object topicalization shares two functional properties with the passive: foregrounding of the patient and de-topicalization of the agent. This fact makes one wonder why the former occurs far less frequently in written text. The present paper is an attempt to illuminate some properties of object topicalization not shared by the passive. It is argued that while object topicalization may de-topica...

In this context, the French research program “GEOBS: Spatial Data Infrastructure in the informational governance for environment” (2015-2018) led by the French National Centre for Scientific Research (CNRS) considers SDI as a real object of study for a better understanding of the flows of environmental information. For this purpose, we are developing a prototype observatory based on content and...

Existence of ex post incentive compatible mechanisms in models with multi-dimensional signals and interdependent values is possible when there are no consumption externalities. An ex post incentive compatible mechanism is constructed in a model where a single indivisible object is allocated among several buyers with multi-dimensional information and interdependent values. It is the combination ...

In order to achieve the virtual machines live migration, the two "pre-copy" and "post-copy" strategies are presented. Each of these strategies, depending on the operating conditions of the machine, may perform better than the other. In this article, a new algorithm is presented that automatically decides how the virtual machine live migration takes place. In this approach, the virtual machine m...
