Abstract
The attentional blink (AB) is a phenomenon where individuals fail to detect a second target in a rapid stream of visual items if it appears within 200-500ms of the first. This study investigated the neural mechanisms underlying the AB using multivariate encoding analyses of EEG data during a rapid serial visual presentation (RSVP) task. The results showed that feature selectivity is enhanced for correctly reported targets and suppressed when targets are missed, suggesting that the AB involves both short- and long-range neural interactions between competing visual representations for conscious access.
