Simple reaction speed
To assess simple reaction speed, the S1 version of the Reaction Time test was administered. Participants were required to respond to randomly generated light stimuli in the form of a yellow circle appearing at different time intervals (ranging from 2.5 to 6.0 s) at the bottom center of the screen. A total of 28 stimuli were presented during the test. To begin the test, participants placed their index finger on the ‘waiting key’ and in response to the stimulus, the finger was moved from the ‘waiting key’ to the ‘response key’. After the response was made, the finger returned to its initial position. Participants were instructed to respond to the visual stimuli as quickly as possible. Two variables were calculated: simple reaction time (ms), defined as the interval of time between the appearance of the stimulus and lifting the finger from the ‘waiting key’, and simple motor time (ms), which characterizes the interval of time from lifting the ‘waiting key’ to pressing the ‘response key’.
