Maisto and Jerome (1977) reported differences in reaction-time (RT) performance between retarded and nonretarded adolescents. They used the additive factor method, and their results showed differences in the speed of active memory scanning between the two populations; however, they violated a critical assumption underlying interpretation of the results, as there was nonindependence of the slope and intercept values of the function relating memory load to RT of retarded subjects. This departure from theoretically acceptable conditions makes the Maisto and Jerome data difficult to interpret.
迈斯托和杰罗姆（1977年）报告了智障青少年与非智障青少年在反应时（RT）表现上的差异。他们采用了加法因素法，结果显示这两类人群在主动记忆扫描速度上存在差异；然而，他们违背了结果解释所依据的一个关键假设，因为智障受试者的记忆负荷与反应时之间关系函数的斜率和截距值并非相互独立。这种偏离理论上可接受条件的情况使得迈斯托和杰罗姆的数据难以解释。
