This experiment investigated the effects of attentional shift by central spatial cueing on the target identification process. The target was defined by a combination of color and shape of an alphabet. Reaction times (RTs) and event-related potentials (ERPs) to stimuli that were preceded by a valid or by an invalid positional cue were recorded. RTs to the target were shorter in valid trial than in invalid trial. In contrast, negative responses to irrelevant color stimuli were faster in invalid trial than in valid trial. Attentional shift did not affect the occipital P1 and N1 components of ERPs. However, midline and contralateral ERPs in valid trial were more negative than those in invalid trial in the latency range of 210 - 260 ms, irrespective of type of stimulus. These results suggest that the activated processes in the transient attentional shift are different from those in the sustained attention situation. Furthermore, the facilitation of the perceptual processing of validly cued stimuli does not necessarily result in the advantage of performance.
