On Mathematicians' Eccentricity

The eccentricity effect: target eccentricity affects performance on conjunction searches.

The serial pattern found for conjunction visual-search tasks has been attributed to covert attentional shifts, even though the possible contributions of target location have not been considered. To investigate the effect of target location on orientation x color conjunction searches, the target's duration and its position in the display were manipulated. The display was present either until obs...

Multifaceted Mathematicians

Murderers , Mathematicians ∗

This article outlines the history of our visualization of the interior of the human body. It throws some light on the emotional context and the underlying idea of man. In order of appearance on the historical stage, the leading characters are: painters, murderers (more precisely: executed persons including thieves driven merely by need, women with illegitimate children, etc.), and mathematician...

Eccentricity effects on lateral interactions

We attempted to resolve an apparent conflict between the lack of psychophysical evidence of collinear facilitation at the near-periphery and physiological evidence from the monkey showing collinear effects extra-fovealy. We compared collinear and orthogonal configurations to discount facilitation due to reduced positional uncertainty. Detection thresholds were measured for Gabor targets at ecce...

On multiplicative Zagreb eccentricity indices

Abstract Analogues to multiplicative Zagreb indices in this paper two new type of eccentricity related topological index are introduced called the first and second multiplicative Zagreb eccentricity indices and is defined as product of squares of the eccentricities of the vertices and product of product of the eccentricities of the adjacent vertices. In this paper we give some upper and lower b...
