Claim:
1. A method of measuring user reaction times to a visual stimulus on a portable touch screen device having a capacitive touch-sensitive surface with a touch reporting mechanism, and one or more modules at least partially implemented in software, said one or more modules being responsive to a user start command to a) open a time log file on receipt of said start command, b) generate a visual stimulus at a first location on the touch screen surface for touch by a user, c) generate at least one second visual stimulus at a second location on the touch screen surface spaced from said first location and write time of generation of the second visual stimulus to a log file signifying such time of generation (Tv), d) receive notification of capacitance sensed touch and coordinates of such sensed touch and write timer time to a log file (Tc) signifying time of such sensed touch and also write the sensed touch coordinates location to a file, e) remove the second visual stimulus from the touch screen surface, steps b)-e) comprising a single trial, f) repeat steps b)-e) until a set of trials signified by a predetermined number of capacitance sensed touches (Tc) of said second location attains a preset number, then cease repeating steps b)-e), and close the log file onto a computer readable medium which may be in said device or in communication with said device, and g) in a computing device which may be the same as said portable device or another computing device having one or more modules implemented at least partially in software and to which the data from said portable device is transmitted, determine a user reaction time (RT) by
