The 'shrinking circle illusion' is a shrinking ellipse.

abstract：:Our aim has been to study visual search in hierarchical patterns through a computational neuroscience perspective. In this way we were able to analyse the relationship between the global precedence effect and attention. The theoretical part of our investigations extended a model built upon the biased-competition hypot...
