Attentional blink (AB) is a phenomenon that makes it difficult to detect the second target (T2) when it is presented within a short time interval of the first target (T1). It has been reported that by experiencing the rapid serial visual presentation (RSVP) task using T2 with enhanced perceptual salience for about an hour, AB is reduced, and this training effect lasts for several months. Previous studies suggest that this training improves the temporal aspect of attention control, the lack of which causes AB. In this study, we examined whether training in the RSVP task improved not only the temporal aspect of attention, but also the spatial orientation of attention. Specifically, by presenting the RSVP streams in the left and right visual fields at the same time, a two-stream RSVP task that adds spatial factors to the conventional RSVP task was performed, where T1 was presented in the left visual field and T2 in the right visual field. It was investigated whether there was a change in the amount of AB before and after the training. As a result, it was found that the training reduced AB to the same extent under all conditions of the presentation fields of T1 and T2. This result suggests that training with increased perceptual salience of T2 improves the ability to localize attention across visual fields.
