The problem
Imagine watching letters flash rapidly in one place, looking for B and then K among other letters. You may identify B but miss K when it follows soon afterward, although K is easy to identify alone. What makes the first target interfere with reporting the second? This attentional blink is a laboratory measure of rapid target processing, not an eyelid blink.[1] [2]
A second target in a rapid image sequence can be harder to report shortly after the first than at a longer interval. How do identity representation and later response competition combine to create this attentional blink? Scalp electrical recordings, or EEG, let researchers compare patterns associated with different target images. A natural-image study found reduced late representational markers at short intervals. A separate 2026 manipulation found less blink when the targets required compatible responses. These results constrain different stages rather than establishing one complete causal sequence.[1] [2]
Scope
Causal integration of target representation and late-stage competition in the human attentional blink during rapid visual streams.
What remains open
EEG decoding identifies altered target representations. The 2026 response-congruence manipulation supports late competition, but does not settle their full causal relationship or generality across paradigms.[1] [2]
Why it matters
A person’s failure to report the second target can be mistaken for evidence that its image was never processed. The representation and response results make that inference unsafe: the task asks about both what the brain encodes and what the participant can use to answer. Separating these contributions matters when laboratory performance is used to infer the timing and capacity of perception.[1] [2]

EEG
Electroencephalography records electrical activity at the scalp. Patterns can carry information about target processing without directly revealing every underlying causal neural interaction.[1] [2]
response congruence
Compatibility between the responses a task assigns to two targets. In the cited experiment, changing it affected the blink; it is not simply how similar the target images look.[2]

Natural-image EEG study identifies reduced late target-representation markers during the blink, not an exhaustive causal processing sequence.

Notes on Direct evidence of inter-target response competition for limited resources in attentional blink
Compatibility manipulation supports late inter-target response competition in a restricted paradigm. This changes interpretation of report failure without explaining every representation process or establishing one mechanism across all blink tasks.
