Abstract:Both reader training and improved map design can be used to increase the communicative effectiveness of maps. Tests with dot densities and circles indicate that either rescaling of symbols (design) or the allowance of some feedback (reader training) will result in more accurate median estimates. The feedback approach, however, is associated with a greater dispersion in estimates, i.e. estimates are less clustered about the median. When both the rescaling and feedback approaches are used, both the medians and dispersion are improved. A different experiment, involving map comparisons, shows that a small amount of reader training can clarify the concept involved in that task and such clarification increases accuracy. While both design modification and reader training induce improvements in map communication, these improvements are different in nature; the two approaches are not substitutes for one another but are complementary.
