Although the frequency and implications of disorders of attention in head-injured subjects have been recognised in recent years, there have been few carefully controlled attempts to evaluate remedial interventions. The present study employed a multiple baseline across subjects design to evaluate a computer-mediated programme for the remediation of deficits in speed of information processing in 10 severely head-injured subjects, aged 17-38 years. Following a baseline period, the effectiveness of computer training alone was compared with that combined with therapist feedback and reinforcement in separate training phases, each lasting 3 weeks. The final phase involved a return to baseline conditions. Dependent measures of attention, taken across all phases, included psychometric measures of processing speed, a rating scale completed by the patient's Occupational Therapist, and a video of the patient working in therapy. Results suggested that, once spontaneous recovery and practice effect were controlled, the patients showed little response to the interventions in terms of the dependent measures used.
尽管近年来人们已经认识到头部受伤患者注意力障碍的频率及其影响，但很少有经过严格控制的尝试来评估补救干预措施。本研究采用跨受试者多基线设计，以评估一个计算机介导的程序，用于改善10名年龄在17 - 38岁之间的重度头部受伤患者的信息处理速度缺陷。在基线期之后，在单独的为期3周的训练阶段，将单纯计算机训练的效果与结合治疗师反馈和强化的训练效果进行了比较。最后一个阶段恢复到基线条件。在所有阶段进行的注意力相关测量指标包括处理速度的心理测量指标、由患者的职业治疗师完成的评定量表，以及患者在治疗中工作的视频。结果表明，一旦控制了自发恢复和练习效应，就所使用的测量指标而言，患者对干预措施几乎没有反应。
