平衡设计在认知心理学中无处不在。然而，研究人员很少对这些设计进行最佳分析，因此降低了实验的功效。在一个简单的启动实验的背景下，几个理想化的数据集被用来说明忽略平衡的可能成本，并建议更适当的分析。这些建议适用于对受试者的影响和刺激项目的影响的可靠性的评估。
Counterbalanced designs are ubiquitous in cognitive psychology. Researchers, however, rarely perform optimal analyses of these designs and, as a result, reduce the power of their experiments. In the context of a simple priming experiment, several idealized data sets are used to illustrate the possible costs of ignoring counterbalancing, and recommendations are made for more appropriate analyses. These recommendations apply to assessment of both reliability of effects over subjects and reliability of effects over stimulus items.
