Abstract

Studies have established that left and right actions are carried out faster when they spatially correspond to the stimulus signalling them, demonstrating the Simon effect. While the focus has been primarily on investigating this effect with a wide range of stimulus variations and cognitive abilities, limited research is available on investigating the influence of handedness on performance in the Simon task. The present study hypothesised that reaction times in the Simon task would differ across three groups (left-handed: n = 29, right-handed: n = 30, and ambidextrous: n = 26). Participants completed an online-based Simon task, in which they responded to the direction of left or right-pointing arrow appearing left or right from a fixation point. The Simon effect was larger in right-handed participants when the position of the arrow and the direction of the arrow were similar. Right-handed participants were also slowest in all conditions, irrespective of the position of the stimuli. However, the average speed of correct responses and percentage errors did not significantly differ when compared between the handedness groups. Further analyses showed that reaction times were fastest in the congruent condition and slowest in the incongruent condition. The results are discussed in light of the implications that they pose for ergonomics research and practice. Recommendations for future work are also presented.
