Detecting Words in Two Streams at High Rates

We have also done work with word targets presented among number and symbol strings, extending the attentional blink procedure described above to rates of 19 items/s and using two simultaneously presented sequences of stimuli. Interestingly, at very short intervals between targets (such as 53 ms), the second target is actually more likely to be seen than the first target. At longer intervals, we obtain the familiar attentional blink pattern in which the first target is more likely to be seen. In further studies with this task we have found substantial effects of semantic priming.
