Coincident timing by 15 nondisabled individuals, 15 mentally retarded and 15 traumatically brain injured was measured under varying target-exposure conditions. Absolute constant error, constant error, and variable error were analyzed in separate repeated-measures analyses of variance for early performance (first block of practice), late performance (last block of practice), and retention (last block of retention). Subjects with mental retardation displayed the least accurate and most variable coincident-timing responses. Nondisabled subjects were most influenced by target-exposure time; subjects with traumatic brain injury were most influenced by target-viewing distance; and subjects with mental retardation were most influenced by a combination of target velocity and target-viewing distance. Subjects with mental retardation displayed a too-early response bias, while nondisabled subjects tended to have a too-late response bias. Individuals with traumatic brain injury had a variable response bias.
在不同的目标暴露条件下，对15名非残疾个体、15名智力迟钝者和15名脑外伤患者的同步计时进行了测量。在针对早期表现（练习的第一组）、晚期表现（练习的最后一组）和保持（保持的最后一组）的单独重复测量方差分析中，分析了绝对恒定误差、恒定误差和可变误差。智力迟钝的受试者表现出最不准确且最具变化性的同步计时反应。非残疾受试者受目标暴露时间的影响最大；脑外伤患者受目标观察距离的影响最大；智力迟钝的受试者受目标速度和目标观察距离组合的影响最大。智力迟钝的受试者表现出反应偏早的倾向，而非残疾受试者往往有反应偏晚的倾向。脑外伤患者有可变的反应偏差。
