Participants are shown a rapid series of letters, which includes a target letter which they must remember. There may or may not be a non-target letter appearing after the target in the list, and they are asked to note whether or not it appears.
The attentional blink occurs after a stimulus is responded to, when other stimuli are not perceived as quickly or accurately.
In this experiment a series of black letters and one white target letter appear on a grey background. A black, non-target letter may appear after the target letter. After each series of letters, participants respond and press the same key as the target letter: Press "A" if "A" appears, etc. Also, respond "1" for yes and "2" for no to answer if the non-target letter appeared or not. This experiment has 160 trials.

Cited Experiment Abstract
To investigate the temporal allocation of attention, a series of 7 experiments using rapid serial visual presentation (RSVP) was designed to examine the relationship of the attentional deficit, or "attentional blink" (AB), recently reported by J.E. Raymond, K.L Shapiro, and K.M. Arnell (1992). The principal finding is that AB occurs only when a target is an object and does not occur when the target is defined by a temporal interval. Target detection difficulty as estimated by d' analysis reveals no relationship between the attentional demands of the target and the production of the AB. A late-selection account of this phenomenon is offered in place of the early-selection account advanced in Raymond et al.'s previous report.
