Visual Search Processes and Cognitive Efficiency of Statistical Maps

In this paper, four statistical maps are designed according to a set of the same data and a related atlas, and the targets searching on these statistical maps are tested with the support of the cognitive test software compiled by ourselves.The results show that when we search the target in the statistical maps, the visual system might use parallel process model and serial process model, and the mean reaction time and the correctness of the target searching are affected by the two search models. The cognitive efficiency of the designs of the four statistical maps are discussed and analyzed.
