Time and Error Measures of Human Performance: A Note on Bradley's Optimal-Pessimal Paradox
本文引入人类绩效数据和理论，论证布拉德利的最优-最劣悖论在理论上成立但基于的假设在经验上不可靠，并提出了替代建议。
Human performance data and theory are introduced relative to Bradley's (1975) optimalpessimal paradox. An attempt is made to demonstrate that the paradox, although theoretically sound, is grounded upon assumptions that are empirically untenable. Alternatives to Bradley's recommendations when optimal-pessimal conditions obtain are presented.
