Abstract : The performance effects of excesses of unipolar atmospheric ions were investigated. Seventy subjects were tested on a complex mental task and an additional 70 were tested on a complex vigilance task. Seven ion concentrations were investigated with each task: high positive, high negative, medium positive, and medium negative; three control conditions were also used: high positive and negative combined, medium positive and negative combined, and a low ion condition. Although two of the three me sure analyzed for the vigilance task showed significant ion effects, in both instances the unipolar ion groups were homogeneous, and the differences in question were entirely attributable to the difference between these groups and the low ion group. The most parsimonious interpretation of this finding is that it resulted from some uncontrolled factor in the selection and assignment of subjects or in the conduct of the experiment. (Author)
