Abstract

Two experiments examined the effect of stimulus set, feature or dimension (Garner, 1978), on modes of attention shift to global and local level of a compound stimulus. In Experiment 1, an analysis of inter-trial transitions of attended levels showed a level shift effect in the feature set compared to no such effect in the dimension set. In Experiment 2, attention shift between levels of the compound stimulus was forced by presenting identities of the two levels in sequence. Attention shift to the local was easier in the feature set than that to the global. In the dimension set, however, shift to the global was easier than shift to the local, and giving attention to either level appeared to be fast and stable. These results imply global precedence (Navon, 1977) is not a general rule and stimulus structure should be considered as an important factor in the study of precedence. The level‐readiness effect (Ward, 1982) and the stages of spatial attention shift (Posner, 1988) were considered in the general discussion.
