Abstract: | Reports an error in the original article by Rotton et al (Journal of Applied Psychology. Vol 67(2) Apr 1982, 230-238). It was erroneously stated that stock solutions contained 45 g/l and 225 g/l of sodium nitrate in Experiments 1 and 2, respectively. Actual levels were 10 times less (i.e , 4.5 and 22 5 g/l). (The following abstract of this article originally appeared in record 1982-20688-001.) In Exp I, 42 Ss (mean age 30.4 yrs) tracked a moving target and monitored lights after receiving sublingual drops that contained either water, sodium nitrate (4.5, 45, 450, or 4,500 ppm), or sodium fluoride (.1, 1, 10, or 100 ppm). Dosage levels equaled, exceeded, or fell below those of municipal waters. In Exp II, 20 females performed this task after receiving sublingual drops of the same test substances in a repeated measures design; dosage levels equaled or exceeded levels found in municipal waters by 100 or 500 times. Neither type nor amount of chemical affected primary task performance; however, after receiving sublingual drops in Exp I, Ss paid less attention to lights on their right. In Exp II, Ss made more errors and had longer response latencies after they received moderate and very high concentrations of test substances. It is concluded that challenge testing is a safe but effective technique for provoking and studying reactions to chemicals when combined with a sensitive measure of sensorimotor performance.
