起搏听觉系列加法测验(PASAT；Gronwall，1977；Gronwall&Sampson，1974)是一种对轻度创伤性脑损伤(MTBI)敏感的注意力和信息处理速度的测量方法，但它对许多其他神经损伤患者是厌恶和不合适的。本研究在74名大学生(26名有脑外伤病史)的样本中考察了PASAT的一种更简单、更不令人反感的视觉模拟测验(有节奏的视觉序列加法测试；PVSAT)。结果表明，PVSAT与PASAT呈中度相关，难度低于PASAT。这两项测试与其他注意力指标有着相同的关系。在大学人群中，PVSAT、PASAT或其他注意测量都没有将MTBI参与者与正常对照组区分开来。因此，这项初步研究证明了这两项测试的可比性，并提出了PVSAT作为PASAT的可行替代方案。讨论了这些研究成果的未来研究和应用方向。
The Paced Auditory Serial Addition Test (PASAT; Gronwall, 1977; Gronwall & Sampson, 1974) is a measure of attention and information processing speed sensitive to mild traumatic brain injury (MTBI), but it is aversive and inappropriate for many other neurologically impaired patients. This study examines a simpler, less aversive visual analog of the PASAT (the Paced Visual Serial Addition Test; PVSAT) in a sample of 74 college students (26 with a history of TBI). Results indicated that the PVSAT is moderately correlated with and less difficult than the PASAT. Both tests had identical relations to other measures of attention. Neither the PVSAT, PASAT, nor the other attentional measures differentiated participants with MTBI from normal controls in a college population. This preliminary study thus demonstrates the comparability of the two tests and presents the PVSAT as a viable alternative to the PASAT. Directions for future research and applications of these findings are discussed.
