W判断是一种广泛使用的意图时间感知估计。这些判断通常是通过使用经典的利贝特式范式来获得的,即要求参与者通过使用钟面上旋转物体的位置来估计他们意识到自己的行为意图的时间。在以前的研究中使用的Libet时钟参数存在不一致性,目前还不清楚这种变异性是否会影响W判断和其他结局指标,并影响该指标的结构效度和研究结果的普遍性。在这里,我们提出了一个四个实验研究,系统地操纵利贝特时钟速度,时钟标记的数量,时钟指针的长度和类型的时钟半径,以检查这些参数的操作是否影响意图定时意识的估计。我们的研究结果表明,W判断可以显着影响的时钟速度和时钟标记的数量。这些结果的意义和影响进行了讨论。
W judgments are a widely used intention timing awareness estimate. These judgments are typically obtained by using the classic Libet-style paradigm whereby participants are asked to estimate the time they become aware of their intention to act by using the location of a rotating object on a clock face. There is an inconsistency in the Libet clock parameters used in previous studies, and it is unclear whether this variability impacts W judgments and other outcome measures, with implications for the construct validity of this measure and the generalisability of results across studies. Here, we present a four-experiment study that systematically manipulated the Libet clock speed, number of clock markings, length of the clock hand and type of clock radius in order to examine whether these parameter manipulations affect intention timing awareness estimates. Our results demonstrate W judgments can be significantly influenced by the clock speed and number of clock markings. The meaning and implications of these results are discussed.
