Two successive, spatially overlapping human faces were exposed for recognition with SOAs ranging from 20 to 160 msec. The subjects effectively perceived one face, which at short SOAs mostly resembled the first stimulus and with increasing SOAs gradually shifted towards the appearance of the second, dimmer stimulus. These results replicated those from the study by Calis, et al, and extended them to the experimental conditions of controlled simultaneity of each of the two temporally separate, extremely brief stimuli and to the conditions of personally unfamiliar stimulus-subjects. In the second experiment we employed a direct measurement of the microgenetic focus in real time by using a procedure by which the subjects' judgments about the relative temporal order of the critical visual stimulus and an auditory click were recorded. Via this procedure it was shown that one of the effects of the first visual stimulus is to speed up the microgenetic process for the second stimulus which then appears subjectively earlier as compared to the single-stimulus control.
呈现两张连续且空间上重叠的人脸以供识别，刺激呈现间隔（SOA）范围为20至160毫秒。受试者有效地感知到一张脸，在短SOA时，这张脸大多类似于第一个刺激，随着SOA增加，逐渐向第二个较暗刺激的外观转变。这些结果重复了卡利斯等人研究的结果，并将其扩展到两个时间上分开的极短刺激中每个刺激的同时性得到控制的实验条件，以及刺激对象为个人不熟悉的条件。在第二个实验中，我们通过一种程序实时直接测量微观发生焦点，该程序记录了受试者对关键视觉刺激和听觉咔哒声相对时间顺序的判断。通过这个程序表明，第一个视觉刺激的作用之一是加速第二个刺激的微观发生过程，与单刺激对照相比，第二个刺激随后主观上出现得更早。
