Abstract:In this study a visual Simon task (standard and crossed- hands subtasks) was used to compare the performance and the size of a Simon effect between deaf (n=15) and hearing (n=15) individuals. Due to auditory sensory deprivation and consequently enhancements of visual perception in deaf participants, faster reactions to peripherally presented stimuli and an increased Simon effect were expected. Reaction times and the amount of errors showed comparable results for the two groups, not confirming earlier findings that postulate an enhancement of peripheral attention and thus better performance of deaf participants (e.g. Reynolds, 1993). An interaction between compatibility and group in the crossed-hands subtask indicated an enhanced Simon effect of deaf participants. Some developmental modulations of the visual system could be detected in this study.
