Abstract

A series of experiments were conducted to explore how the attention mechanism controls the stimulus probability effects and also global vs local precedence phenomena. We varied the nature of hierarchical stimulus sets based on Garnet's (1978) approach and the probability of the level that should be filtered in the stimulus pattern. Stimulus sets significantly altered precedence phenomena. Stimulus probability also modulated the magnitudes of interference in regard to either global or local precedence. The pattern of results indicates that attention to a given level influences a mode of precedence via changing the activation level of the name codes in a hierarchical pattern. Implications of our results were discussed in view of several precedence models.
