Left handed simple, recognition and choice reaction times

الملخص

In this study, 27 left handed healthy volunteers (12 male and 15 female) aged between 18 and 23 yrs were included in reaction time (RT) test that include simple reaction time (SRT), Recognition reaction time (RRT) and Choice reaction time (CRT). It’s appeared from the results that, SRT for the central target colors was less than for the peripheral on white and black background. The individual ability in recognizing the colored targets depends on the contrast of these colors with the background, when the contrast increased the individual ability to response increase. Two back targets RRT for individuals were longer than one back targets. Using the two hands together for individuals produces a faster CRT than using one hand only.
