The visual characteristics of common geographical map forms are studied by instructing subjects to rank-order sets of maps in terms of their degree of correlation with referent displays. Experimental variables include subject experience 6 levels, map complexity 5 levels, and cartographic technique 5 types. The experience and complexity main effects were highly significant, as was graphiccomplexity interaction. As the comparison task became more difficult subjects tended to overemphasize spatial auto-correlation at the expense of spatial cross-correlation, and the results support prior evidence suggesting that the human eye functions as a high pass filter i.e., focuses on pattern detail.
