An attempt was made to examine one specific aspect of response complexity - accuracy demand. Three groups, each of 12 subjects, were presented with two parallel lines of dots on a moving paper strip. Dots were in pairs at random intervals, and subjects were required to cross over the dots with a pen when a tone sounded. Subjects were required to cross over either zero, one, or two dots sequentially. From zero dots to one dot, there was an increase in reaction time (RT), presumably due to the more stringest error limits required in the latter. RT did not increase from one dot to two dots, but increased movement time (MT) was found. Results suggest that RT involves programming of movement initiation, and that MT includes some programming of the ongoing response. Accuracy demand differentially influenced RT and MT.
研究人员试图考察反应复杂性的一个特定方面——准确性要求。三组，每组12名受试者，在一条移动的纸条上呈现两条平行的点线。点以随机间隔成对出现，当听到音调时，受试者需要用笔画过这些点。受试者需要依次划过零个、一个或两个点。从划过零个点到划过一个点，反应时间（RT）增加，这可能是因为后者要求更严格的误差限制。从划过一个点到划过两个点，反应时间没有增加，但发现运动时间（MT）增加了。结果表明，反应时间涉及运动启动的编程，而运动时间包括一些对正在进行的反应的编程。准确性要求对反应时间和运动时间有不同的影响。
