Resumen
The first aim of this research was to determine whether response inhibition shows the same or different effectiveness as a function of motor complexity. The second aim was to establish how response inhibition works when movements are performed alternately rather than separately. The Simon effect was used as a measure of response inhibition. Sixteen subjects participated in the study and performed the Simon task. Subjects responded with actions of lifting and reaching both separately and alternately. Reaction time, Movement time, Kinematic errors and Movement errors were measured and submitted to repeated measures ANOVAs. Distributional analyses of Simon effect and accuracy rate were performed using delta-plots. We found that the effectiveness of response inhibition differed between actions when they were performed alternately but not in isolation, being stronger on the simpler lifting movement. It can be argued that these results occurred because of a limitation of the available resources and a subsequent control strategy to minimize errors.
Key words: Response inhibition; Motor complexity; Simon effect
