To understand how the brain shields a planned action against irrelevant attentional capture, we conducted a series of five accessory signal (AS) Simon tasks, where an irrelevant peripheral stimulus is presented on different points in time, relative to the response signal. Response information (colour) was presented centrally, either 600 ms prior to or together with a go/nogo signal (shape). When presented just before or simultaneously with the go signal, the AS elicited a Simon effect. When presented 150 ms after the go signal and colour was presented prior to the go signal, the Simon effect reversed. When colour and go/nogo information were presented together, the reversal disappeared. If only one stimulus dimension (colour) was used for both decisions, the reversed Simon effect reappeared when the AS was presented 300 ms after the go signal. The results are interpreted in terms of event-file binding and inhibition of the exogenous AS activation.
