Attentional blink is the brief period after you notice one visual target when a second target is likely to be missed, usually within 200 to 500 milliseconds. In Cognitive Psychology, it shows the limits of attention during fast visual tasks.
Attentional blink is a short failure to notice a second visual target because your attention is still busy processing the first one. In Cognitive Psychology, this is one of the clearest examples of how attention is limited, even when you feel like you are tracking everything in front of you.
The classic setup uses rapid serial visual presentation, or RSVP. You see a fast stream of letters, words, or pictures, and you have to report two target items that appear close together. If the second target shows up too soon after the first, often around 200 to 500 milliseconds later, people are more likely to miss it. That gap is the attentional blink.
This does not mean your eyes failed to receive the second stimulus. The sensory input may still reach you, but attention has not fully reset yet. The first target is taking up processing resources, so the second one gets less priority and may never become conscious. That is why attentional blink is often discussed alongside selective attention and limited-capacity processing.
The effect is not the same as simply being distracted all the time. It is time-locked and highly specific. If the second target appears later, or if the two targets are separated by enough time, detection improves again. Researchers use that timing pattern to show that attention is not a perfect stream, but a system with temporary bottlenecks.
Some targets are less likely to disappear in the blink period. Emotionally charged or highly noticeable items can stand out enough to break through. Practice can also reduce the effect, because you get better at handling the RSVP task and distributing attention across rapid input. That makes attentional blink a useful case for studying both the limits of attention and how experience can change performance.
Attentional blink matters because it gives you a clean way to talk about limited attention in Cognitive Psychology without guessing. It shows that perception is not the same as awareness, and that noticing one thing can temporarily suppress the next thing in a fast stream.
That idea connects directly to topics like selective attention, inattentional blindness, and the bottleneck model. If a scenario describes someone missing a second message, a second visual cue, or a second target in a rapid sequence, attentional blink is often the right explanation. It also helps you separate attention problems from memory problems, since the miss happens before the second item is fully processed.
The concept also matters in real tasks where information arrives quickly, like monitoring screens, driving, sports, or medical scanning. In those settings, the issue is not just seeing less. It is that the mind has a brief recovery period after one item gets priority, and that can affect what you notice next.

Selective attention is the broader system that lets you prioritize one stimulus over others. Attentional blink is one specific limit within that system, because the second target gets filtered out while the first target is still being processed. If you are asked why someone notices one item but misses the next one in a fast sequence, selective attention explains the general process and attentional blink explains the timing pattern.
Inattentional Blindness
Inattentional blindness happens when you miss an unexpected stimulus because attention is focused elsewhere. Attentional blink is different because the missed item appears right after a first target in a rapid stream, not just anywhere in the scene. Both show that seeing something does not guarantee awareness, but attentional blink is more about brief processing limits than about unexpected events.
Bottleneck Model
The bottleneck model says that some stages of attention can only handle a limited amount of information at once. Attentional blink gives evidence for that idea, because the first target seems to occupy processing space and slows access for the second target. In an essay or short answer, this is a good way to explain why the second stimulus is missed even though it was presented.
Cognitive Load
Cognitive load refers to how much mental effort a task demands at a given moment. During attentional blink, the first target increases the load on your attention, so the system has less capacity to process the second target. This connection is useful when a question asks why performance gets worse during rapid, information-heavy tasks.
A quiz item or short-answer question may show a fast series of letters, words, or images and ask why the second target was missed. Your job is to identify attentional blink, not just say the person was distracted. If the prompt includes a rapid sequence with two targets, mention the timing window, usually about 200 to 500 milliseconds, and explain that the first target is still being processed.
In an essay or case analysis, use the term to explain why attention has a short recovery period. If the scenario involves screen monitoring, driving, sports, or any RSVP-style task, connect the missed item to limited attentional capacity. You can also compare it to inattentional blindness if the question is testing whether the miss came from a fast sequence or from focusing on something else.
These get mixed up because both involve missing something that was actually presented. Attentional blink is about missing a second target in a rapid sequence after the first one grabs attention. Inattentional blindness is about failing to notice an unexpected stimulus because attention is focused on another task or object.
Attentional blink is the brief period after noticing one target when a second target is harder to detect.
The effect usually shows up in rapid serial visual presentation tasks, where items appear in a fast stream.
The second stimulus is missed because attention is still processing the first one, not because the eyes failed to receive it.
The phenomenon supports the idea that attention has limits and can hit a temporary bottleneck.
Practice and emotionally salient stimuli can reduce the blink effect, but they do not erase the basic limit.
Attentional blink is the brief period after one visual target is noticed when a second target is likely to be missed. It usually happens in very fast sequences, so it is used to show that attention cannot fully process two close-together items at the same time.
Researchers often use rapid serial visual presentation, or RSVP, where letters, words, or images flash by quickly and you report target items. If the second target appears too soon after the first, people often miss it, which reveals the temporary limit in attention.
No. Attentional blink happens when a second target follows closely after a first target in a rapid stream. Inattentional blindness happens when you miss something unexpected because your attention is focused elsewhere. They both involve missed awareness, but the cause is different.
It shows up in situations where information arrives fast, like driving, monitoring a display, or watching quick sports action. If your attention is tied up with one event, you can briefly miss the next one, which is why the effect matters outside the lab.
