On the perception of symmetrical and repeated patterns. Corballis, M. C. & Roldan, C. E. Percept Psychophys, 16(1):136–142, Psychonomic Society, 1974. abstract bibtex 4 experiments with a total of 116 university students investigated rapid perceptual judgments about tachistoscopically presented patterns that were either symmetrical about or repeated across a vertical axis. The same patterns were presented under 2 different instructional conditions: some Ss were to judge the 2 halves of each pattern "same" or "mirror"; others were to judge each pattern as a whole "symmetrical" or "asymmetrical." With dot patterns, reaction times (RTs) were faster for symmetrical than for repeated patterns when the 2 halves were close together, but not when they were separated, regardless of instructions. With simpler patterns made up of arrowheads and C-shapes, however, same RTs were faster than mirror, but asymmetrical RTs were marginally slower than symmetrical, regardless of spatial separation. The advantage of same over mirror did not seem to be simply a labeling effect. Results suggest that left-right symmetry was perceptually more salient than left-right repetition when the patterns were perceived holistically. By contrast, distinct patterns could be matched more rapidly when they were the same than when they were left-right mirror images. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
