60 subjects estimated the duration of the stimulus consisting of 1, 3, or 5 dark dots, following the auditory warning signal. The duration of the warning signal constituted duration of foreperiod which was either 1 or 5 sec. For the correlated groups, pitch of the warning signal weas perfectly correlated with numerosity of dots. For the uncorrelated group, there was no such correlation. For the constant group, pitch of the warning signal was constant. The increasing effect of numerosity of stimulus elements was reduced for the 5-sec foreperiod but not for the 1-sec. foreperiod in the correlated group. Such effect was present for both durations for foreperiod in the uncorrelated group and was absent for both durations of foreperiod in the constant group.
60名受试者在听到听觉警告信号后，估计由1、3或5个黑点组成的刺激的持续时间。警告信号的持续时间构成了1秒或5秒的前周期持续时间。对于相关组，警告信号的音高与点的数量完全相关。对于不相关组，不存在这种相关性。对于恒定组，警告信号的音高是恒定的。在相关组中，刺激元素数量的增加效应在5秒前周期时减小，但在1秒前周期时没有减小。在不相关组中，两种前周期持续时间都存在这种效应，而在恒定组中，两种前周期持续时间都不存在这种效应。
