Noise, S-R compatibility and hand dominance

The present study investigated the importance of task parameters in determining the effects of noise on performance, with interest focusing on variables which influence response selection and execution. The results of the first experiment showed that noise had an effect on response selection, slowing reaction times when an incompatible response had to be made. In contrast to this, the second experiment showed that noise had no effect on the speed of controlled movements and did not change the difference between movements made with the preferred and non-preferred hands.
