Abstract

Grouping by configuration was studied in two experiments using a visual search paradigm(conjunction and preview search). We used two kinds of grouping: orientation (Exp 1) andtexture grouping (Exp 2) and there were two kinds of configuration (regular and irregular).Regular configurations facilitated search compared to irregular configurations (Exp 1 and2). Grouping by orientation was influential in preview search (Exp 1) and grouping bytexture had an effect on conjunction search (Exp 2). The role of configuration based ondifferent dimensions in search is discussed.
