三组头部受伤的患者与匹配的对照组进行了反应时间（RT）任务的比较。第一组包括以前住院的头部损伤的严重程度，在不同的时间间隔受伤后进行评估的门诊病人。第二组由未住院的轻度脑震荡患者组成。第三组由不同严重程度的头部受伤患者组成，这些患者在首次住院后7-10个月进行评估。 反应时间测试按难度分级，从简单的RT反应到复杂的选择RT测试。此外，受试者在他们的能力，忽略冗余信息在一个选择RT测试。研究结果表明，创伤性脑损伤导致信息处理速度减慢，注意力分散，注意力集中障碍和表现不一致。
Three groups of patients who had suffered head injury were compared with matched control subjects on reaction time (RT) tasks. Group I consisted of outpatients previously hospitalised for head injury of wide ranging degrees of severity, assessed at varying intervals after injury. Group II was composed of non-hospitalised mildly concussed patients. Group III was made up of head injured patients of varying degrees of severity assessed 7-10 months after initial hospitalisation for their injury. The reaction time tests were graded in difficulty, from a simple RT response to a complex choice RT test. In addition, subjects were compared in their ability to ignore redundant information during one of the choice RT tests. The findings indicate that traumatic brain injury causes slower information processing, deficits in divided attention, an impairment of focused attention, and inconsistency of performance.
