The purpose of this study is to explore the effects of both individual spatial cognitive styles and spatial stimulus-response （S-R） patterns on average choice reaction time. The experiment employed a 2 （individual spatial cognitive styles） ×2 （spatial S-R pairing patterns） split-plot design. The individual spatial cognitive styles used field-dependent-independent （FDI） cognitive styles that were tested with Riding's computer-administered Cognitive Styles Analysis （CSA）. The spatial S-R pairing patterns used correspondent spatial S-R pairing task and non-correspondent spatial S-R pairing task. Analysis of variance showed that both individual spatial cognitive styles and spatial S-R pairing patterns were significant. Further, it was found that the difference in the FD participants' performances between the two different spatial S-R pairing pattern tasks varied more significantly than the difference in the FI participants' performances （the FD participants performed significantly more slowly than the FI participants in the non-correspondent spatial S-R pairing task than in the correspondent spatial S-R pairing task）. This indicates that spatial-cognitive individuals performed differently in different spatial S-R pairing pattern tasks, and demonstrates the important role of selecting operator for spatial S-R pairing tasks, especially in the advanced control room.
