本研究检测了3组创伤性脑损伤（TBI）儿童伤后24个月的持续注意能力：（a）轻度TBI（n = 24），（B）中度TBI（n = 31），（c）重度TBI（n = 14）。本研究采用三种传统的连续操作测试范式（CPT），探讨影响CPT操作的因素，包括加工速度、注意失误和刺激复杂度。TBI组之间在简单反应时间的测量上没有明显差异，也没有在刺激间隔延长的CPT版本上。然而，在最复杂的任务上，轻度和重度TBI组之间存在显着差异，这些任务需要速度，准确性和决策，这表明这些因素是先前在重度TBI儿童CPT上确定的受损表现的基础。这些发现对这些儿童的干预计划的发展具有启示意义。
This study examined sustained attention abilities 24 months postinjury, in 3 groups of children who had suffered a traumatic brain injury (TBI): (a) mild TBI (n = 24), (b) moderate TBI (n = 3 1), and (c) severe TBI (n = 14). Three manipulations of the traditional Continuous Performance Test paradigm (CPT) were employed in the study, to delineate factors that might influence CPT performance, including speed of processing, attentional lapses, and stimulus complexity. No significant differences were evident among the TBI groups on a measure of simple reaction time, nor on a CPT version where the interstimulus interval was lengthened. However, there was a significant difference between the mild and severe TBI groups on the most complex task, which required speed, accuracy, and decision making, suggesting that these factors underlie impaired performances previously identified on the CPT in children with severe TBI. These findings have implications for the development of intervention programs for these children.
