Many know the feeling of being too groggy to take an 8AM exam-we need to be more alert and aroused to do our best. Some of us also know the feeling of being too aroused by the prospect of an exam to do our best. Thus, the best level of performance occurs when we are in the Goldilocks zone-not too aroused and not too groggy. Simon and Moghaddam (2016) recently replicated this observation in rats. Subjects were randomly assigned to one of three groups. Each group received a different dose (none, a medium dose, or a high dose) of Ritalin, which is a stimulant. Researchers measured the rats' learning and cognitive performance and observed the highest level of performance in the group that received a medium dose of Ritalin. Suppose that the following data were obtained from a similar independent-measures research study comparing three different treatment conditions. Treatment I - No Drug II - Medium Dose III - High Dose 17 29 16 14 21 24 22 27 20 19 23 21 18 25 19 Score on cog perf Sum of Squares df Mean Square F Sig.
