Mean response times (RTs) from a sample of 13 simple- and choice-reaction time studies (which included 353 Closed-Head Injury (CHI) subjects at various stages of injury and 329 Control, non-CHI, subjects; mean age of both groups, approximately 28 years) were analyzed using Brinley Plot/multiple regression analysis techniques to provide support for the observation that CHI results in a slowing of basic cognitive information processing. Across 101 experimental conditions, the best-fit equation that resulted from regressing the CHI data onto the Control data for matched conditions was Y(CHI)=1.54X(control)-59, and this specific regression equation accounted for approximately 89% of the variance (based on R2). These results suggest that the basic cognition processes involved in simple- and choice-reaction time performance were approximately 1.54 times slower in CHI individuals in this sample as compared to non-CHI individuals. This pattern of performance substantiates the observation the CHI results in a slowing of even very basic cognition information processes.
对来自13项简单反应时间和选择反应时间研究样本的平均反应时间（RTs）进行了分析（该样本包括353名处于不同损伤阶段的闭合性颅脑损伤（CHI）受试者和329名对照非CHI受试者；两组的平均年龄约为28岁），采用布林利图/多元回归分析技术，以支持闭合性颅脑损伤会导致基本认知信息处理速度减慢这一观察结果。在101种实验条件下，将闭合性颅脑损伤数据与对照数据在匹配条件下进行回归分析得出的最佳拟合方程为Y(CHI)=1.54X(对照)-59，该特定回归方程解释了约89%的方差（基于R2）。这些结果表明，与非闭合性颅脑损伤个体相比，该样本中闭合性颅脑损伤个体在简单反应时间和选择反应时间表现中所涉及的基本认知过程大约慢1.54倍。这种表现模式证实了闭合性颅脑损伤会导致甚至非常基本的认知信息过程减慢这一观察结果。
