The ability of human subjects to judge the duration of short empty time intervals was studied in relation to the modality composition of the marker signals. At each trial, a pair of empty intervals was presented by a series of three successive stimuli, and the subject was asked to point out the longer interval of the two. Tone pips and flashes of light were used as the bounding signals. All the possible combinations of auditory and visual stimuli were used, in random order, to delimit pairs of intervals. Performance was found modality-independent when the first two stimuli were of the same modality. Strong response biases were introduced by varying the modality of the first or the second stimulus. Analysis of these biases indicates that memorization of the empty time intervals is affected by the modality of the binding signals.
研究了人类受试者判断短时空时间间隔持续时间的能力与标记信号的模态组成之间的关系。在每次试验中，通过一系列三个连续的刺激呈现一对空时间间隔，并且要求受试者指出两者中较长的间隔。音调和闪光被用作边界信号。随机使用听觉和视觉刺激的所有可能组合来界定时间间隔对。当前两个刺激属于相同模态时，发现表现与模态无关。通过改变第一个或第二个刺激的模态引入了强烈的反应偏差。对这些偏差的分析表明，空时间间隔的记忆受到边界信号模态的影响。
