This experimental procedure is designed to control for placebo effects, as neither the children nor their observers knew which kind of drink each consumed. This means that any observed differences in behavior between the two groups can be attributed to the additives, rather than the children's expectations or beliefs about the drink. Tolerance and withdrawal are not relevant to this experimental design, and the presence of ADHD would need to be controlled for through other means, such as randomization or statistical analysis.
