The influences of the measurement scale on interpretations of age-related slowing are discussed. Although the customary practice is to describe performances as response latencies (sec/response), a plausible alternative is to describe performances as response speeds (responses/sec). Different scales may lead to contradictory conclusions because nonlinear transformations of time (such as speed) reduce or remove age x complexity interactions. Reconciliation is difficult because choice of measure appears more dependent on theoretical than psychometric considerations. Certain assumptions of cognitive theory require that untransformed response latencies serve as the dependent measure, whereas those of behavioral-learning approaches suggest scales that give increasing weight to latency reductions.
讨论了测量尺度对与年龄相关的反应迟缓解释的影响。虽然习惯做法是将表现描述为反应潜伏期（秒/反应），但一种合理的替代方法是将表现描述为反应速度（反应数/秒）。不同的尺度可能会导致相互矛盾的结论，因为时间的非线性转换（如速度）会减少或消除年龄×复杂性的相互作用。调和很困难，因为测量方法的选择似乎更多地取决于理论考虑而非心理测量学考虑。认知理论的某些假设要求未转换的反应潜伏期作为因变量指标，而行为学习方法的假设则建议采用能增加对潜伏期缩短权重的尺度。
