Forest before trees: The precedence of global features in visual perception
a letter while looking at a visual stimulus that consisted of a large character (the global level) made out of small characters (the local level). The subjects' auditory discrimination re- sponses were subject to interference only by the global level and not by the local one. In Experiment 3 subjects were presented with large characters made out of small ones, and they had to recognize either just the large characters or just the small ones. Whereas the identity of the small characters had no effect on recognition of the large ones, global cues which conflicted with the local ones did inhibit the responses to the local level. In Experiment 4 subjects were asked to judge whether pairs of simple patterns of geometrical forms which were pre- sented for a brief duration were the same or different. The patterns within a pair could differ either at the global or at the local level. It was found that global dif- ferences were detected more often than local differences. /'/if Principle of Global Precedence
