The present experiment was carried out to investigate whether the effects of practicing a spatially incompatible task on performance of a subsequent Simon task are related to some episodic/contextual characteristics of the task or are the result of a higher-order remapping of spatial stimulus-response associations. Results show that an acoustic spatially incompatible task yields a reversal of the Simon effect, even when the Simon task is carried out in the visual modality after an interval of one week, thus supporting the latter hypothesis.
