Participants performed an exogenous cueing discrimination task in three situations: at rest, while exercising, and immediately after exercising. The stimulus–response compatibility effect was also measured at each exercise condition.
The results in the rest session showed the typical facilitation effect at the 100 ms Stimulus Onset Asynchrony (SOA) and the inhibition of return (IOR) effect at the 1000 SOA. While the facilitation effect was present in the three exercise conditions and there was not any significant difference in the magnitude of the effect between them, the IOR effect was significant only in the rest session. The stimulus–response compatibility effect was of a similar magnitude in the three exercise conditions.
This study demonstrates that, compared to a rest condition, an acute bout of aerobic exercise performed during or even immediately before the spatial task, modulates the deployment of exogenous spatial attention.
