Most studies that examined the precuing of motor responses have been interpreted as indicating that response specification is a variable-order process. An apparent exception to this conclusion was obtained by Miller (1982) for the preparation of discrete finger responses. Precuing was beneficial only when the precued responses were on the same hand, suggesting that response specification occurs in a fixed order, with hand specified before other aspects of the response. Three experiments examined this discrepant finding for discrete finger responses. Experiment 1 demonstrated that with sufficient time (3 s), all combinations of responses can be equally well prepared. Experiments 2 and 3 showed that the precuing advantage for same-hand responses at shorter precuing intervals is due to strategic and decision factors, not to an ability to prepare these responses more efficiently. Preparation of finger responses, thus, also appears to be variable. This conclusion poses problems for Miller's extension of the precuing procedure to the evaluation of discrete versus continuous models of information processing.
大多数研究运动反应预线索化的实验都被解释为表明反应指定是一个可变顺序的过程。米勒（1982年）在准备离散手指反应时得出了一个明显与这一结论相悖的结果。只有当预线索化的反应是在同一只手上时，预线索化才是有益的，这表明反应指定是以固定顺序发生的，手在反应的其他方面之前就已指定。三个实验检验了这一关于离散手指反应的矛盾发现。实验1表明，有足够的时间（3秒）时，所有反应组合都能得到同样好的准备。实验2和实验3表明，在较短的预线索化间隔下，同手反应的预线索化优势是由于策略和决策因素，而非更有效地准备这些反应的能力。因此，手指反应的准备似乎也是可变的。这一结论给米勒将预线索化程序扩展到评估离散与连续信息处理模型的做法带来了问题。
