A lot of people show a decline in performance when they haveto report a second target stimulus in a stream of distractorstimuli. Curiously, this decline only happens when the secondtarget appears approximately 200-500ms after the first target.Recently, Choi, Chang, Shibata, Sasaki, and Watanabe (2012)have shown that a short, one-hour training can eliminate this“attentional blink”. Up to now, it is still unclear why thistraining works. In this paper, we have evaluated a range ofdifferent training paradigms to test several hypotheses aboutthe mechanism behind the reduction of the attentional blink.Our results show that none of these training paradigms havea large training effect when administered in isolation. Thetraining by Choi et al. (2012) outperforms them all. The mostlikely explanation for this effect are temporal expectationsrelative to the first target.
