In location-precuing experiments, accuracy in discrimination of T-like characters improves with increasing time between the precue and the target. In this experiment, two central and two peripheral cue locations were examined using 13 different cue-target intervals from 0 to 234 msec. Accuracy was the same when trials were cued from the two peripheral locations (two thirds distance between fixation and target or distal to the target location). Centrally cued trials (cues at fixation or next to fixation) resulted in slower onset of attentional effects than peripherally cued trials, but there was greater accuracy at long cue-target intervals for central than for peripheral cues. Data are compared to previously published research.
在位置提示实验中，对类T字符的辨别准确性会随着提示与目标之间时间间隔的增加而提高。在本实验中，使用了从0到234毫秒的13种不同提示-目标间隔，对两个中央提示位置和两个外周提示位置进行了研究。当从两个外周位置进行提示时（位于注视点与目标之间三分之二距离处或目标位置远端），试验的准确性相同。中央提示试验（提示位于注视点或紧邻注视点）比外周提示试验产生的注意力效应起始更慢，但在长提示-目标间隔时，中央提示比外周提示具有更高的准确性。将数据与先前发表的研究进行了比较。
