Based on two previous papers, the physical meaning of synchronization and simultaneity as is presented in Einstein's Special Relativity paper of 1905 is reconsidered. We follow Einstein's argumentation to introduce a criterium of synchronization and for the same arguments we arrive at a different criterium for synchronization. From that we conclude that simultaneity is absolute. Introduction On...

In unisensory contexts, spatially-focused attention tends to enhance perceptual processing. How attention influences the processing of multisensory stimuli, however, has been of much debate. In some cases, attention has been shown to be important for processes related to the integration of audio-visual stimuli, but in other cases such processes have been reported to occur independently of atten...

An evenly convex credal set is a set of probability measures that is evenly convex; that is, a set that is an intersection of open halfspaces. An evenly convex credal set can for instance encode preference judgments through strict and non-strict inequalities such as P (A) > 1/2 and P (A) ≤ 2/3. This paper presents an axiomatization of evenly convex sets from preferences, where we introduce a ne...

Students of the literature on entailment [7], [1] are familiar with the von Wright-Geach definition of entailment [6], [2]: p entails q if, and only if, by means of logic, it is possible to come to know the truth of •"/> D cp without coming to know the falsehood of p or the truth of q. A competitor of the Lewis account of entailment as strict implication, the von Wright-Geach definition has enj...

BACKGROUND When one watches a sports game, one may feel her/his own muscles moving in synchrony with the player's. Such parallels between observed actions of others and one's own has been well supported in the latest progress in neuroscience, and coined "mirror system." It is likely that due to such phenomena, we are able to learn motor skills just by observing an expert's performance. Yet it i...

When moving figures are occluded and revealed piecemeal as they move across a narrow slit, observers may perceive them as integrated but distorted. They may also perceive much more of the figure as simultaneously visible than is actually presented at any moment. We obtained quantitative measures of both the perceived distortion and perceived simultaneity under free viewing conditions and relate...

In this paper, I replicate Erikson and Palfrey (2000) who propose that the simultaneity problem in measuring the effects of candidate spending can be resolved by restricting the sample to close elections. Vote-on-spending effects, which vary with the expected closeness of the election outcome in a systematic way, determine the extent of simultaneity bias. The simultaneity bias becomes progressi...
