Abstract

When participants are asked to identify two targets embedded in a rapid serial visual presentation (RSVP), they hardly identify the second target that is presented within 200-500ms after the first target. This is called an attentional blink (AB). A recent study reported that AB can be removed by the color-salient training in which the second target within 200-500ms is presented in a salient color. The study suggested that the training effect is caused by an improvement of our attentional control mechanism, which is responsible for both target selection and distractor inhibition. Alternatively, however, the training effect might be understood as a result of visual perceptual learning evoked by repetitive exposure to stimuli during the training. The current study tested these two hypotheses through an experiment that consisted of four sessions: a pre-test session, two color-salient training sessions, and a post-test session, in that order. All sessions employed number targets and alphabet letter distractors in RSVP. During the training, only half of eight numbers (from 2 to 9) were randomly selected as targets. Our results showed that even when untrained numbers, which were not used in the training, were employed as targets in the post-test, the training effects occurred, resulting in removal of AB. It supported the hypothesis that the color-salient training effect occurs not as a result of the visual perceptual learning but as a result of improvement in our attentional capacity.
