Factors influence the global dominance with hierarchical stimuli.

Navon (1977), on the basis of hierarchical network model, suggested the processing of a visual pattern proceeds from global level towards analysis of more local details which he termed,global precedence hypothesis. His experiments formed the basis for a line of research directed towards setting limits or generalization of global precedence. The aim of this paper is to realize a theoretical review of the concept of global precedence, empirical measures and task used in experimentation. In addition to this, a review of results obtained in subsequent studies is presented. This includes investigations with experimental manipulation of stimuli variables, studies with neuropsychological approach and studies exploring individual differences.
