The present study investigated the effect of time pressure on dynamic visual search performance in low and high velocity conditions. When the velocity was low in low time pressure condition, the performance had a slight increase but it was not statistical significant. But when the velocity was low and the time pressure was high, there was a significant improvement of search performance. If the velocity was high, performance decreased in high time pressure condition but no significant effect of time pressure on performance was found in both low and high time pressure conditions. The results implied that for dynamic visual search with low velocity, performance can be improved by providing time pressure. When the velocity was low, time pressure is not a factor that leads to performance change. The obtained results could be a reference for deciding the time limit (i.e., the permitted longest search time) for a specific visual search task.
