The Walter Reed palm-held psychomotor vigilance test

Behav Res Methods. 2005 Feb;37(1):111-8. doi: 10.3758/bf03206404.


This field-portable reaction time test and analysis software run on devices using the Palm operating system. It is designed to emulate a test and commercial device widely used in sleep deprivation, shift work, fatigue, and stimulant drug research but provides additional capabilities. Experimental comparisons with the standard commercial device in a 40-hour total sleep deprivation study show it to be comparably sensitive to selected experimental variables. A Pocket PC-compatible version is under developement.
