Relationships between psychological functions and waking dominant posterior rhythm frequency (DPRF) of the EEG were evaluated with and without simultaneous evaluation of epileptiform discharges. Ninety adult epileptics with uncontrolled seizure disorders treated solely by diphenylhydantoin underwent EEGs during wakefulness and administrations of an extensive battery of neuropsychological tests. The DPRF was particularly related to abilities simultaneously requiring attention an complex mental manipulations. Rhythms slower than 7.5-8.0 Hz were accompanied by relatively poorer performance than rhythms which were faster. When epileptiform discharges were considered in combination with the DPRF, larger differences in abilities were demonstrated, and the psycholoigcal correlates tended to be more substantial for the epileptiform discharge variable than for the DPRF variable. The selection of tests employed and the range of rhythms assessed are critical to these findings, and the substantial construction of these variables by many previous investigators is believed to be related to the negative findings often reported.
在有或没有同时评估癫痫样放电的情况下，对脑电图（EEG）的心理功能与清醒时主要后部节律频率（DPRF）之间的关系进行了评估。90名仅接受二苯乙内酰脲治疗且癫痫发作未得到控制的成年癫痫患者在清醒状态下接受了脑电图检查，并进行了一系列广泛的神经心理学测试。DPRF尤其与同时需要注意力和复杂心理操作的能力相关。频率低于7.5 - 8.0赫兹的节律伴随着比频率较快的节律相对较差的表现。当将癫痫样放电与DPRF结合考虑时，能力上的差异更大，并且癫痫样放电变量的心理相关性往往比DPRF变量更显著。所采用测试的选择以及评估的节律范围对这些发现至关重要，并且许多先前研究者对这些变量的大量构建被认为与经常报道的阴性结果有关。
