Computerized and fingertip measures of reaction time compared in individuals

The results of demonstrated that the vast majority of participants, 95.2% of males and 85.0% of females for the right hand and 95.2% of males and 95.0% of females for the left hand had a high level of point biserial coefficient of correlation between the two methods. A small number of participants, 3 females and 1 male, did not demonstrate a high level of correlation. We speculate that this fact may be due to differential expression of muscle fibre types between males and females. The portability and ease of use of the field fingertip method are advantageous in the field research and provide a reliable measure of reaction time. It is important to control the initial gap between the thumb and index finger of the person being tested. A metallic metric ruler is adequate experimental instrumentation. The mass of the dropped item does not influence the measurement.
