What is Attentional Blink
Understanding Attentional Blink
Attentional blink is a phenomenon in which an individual's ability to recognize or identify a second target is impaired or delayed when it appears shortly after the first target. It is simply a period of reduced visual processing capacity following the detection of a first target stimulus. In other words, attentional blink is a delay in the processing of the second stimulus when it is presented in a short time window immediately after the first stimulus.
The attentional blink phenomenon has been extensively studied in cognitive psychology and neuroscience as it is believed to shed light on the way in which attention is allocated and distributed in the human brain. Researchers have found that attentional blink occurs when the first target stimulus is followed by a distractor stimulus within 200-500ms, depending on task demands and the individual's level of attention.
The Mechanism behind Attentional Blink
The mechanism that underlies the attentional blink phenomenon is complex and multifaceted. Studies have shown that it involves the interaction of different cognitive processes such as attention, consciousness, perception, and working memory.
When we process visual information, we use two types of attentional resources - early selection and late selection. Early selection occurs when the brain selectively attends to a specific stimulus before it is fully processed, while late selection occurs when the brain selectively attends to a specific stimulus after it has been fully processed.
The attentional blink phenomenon is thought to occur because of the processing limitations in our working memory. When we are presented with two visual stimuli within a short time frame, our working memory has difficulty processing both stimuli in parallel. As a result, the processing of the second stimulus is delayed or inhibited.
Studies have linked the attentional blink phenomenon to the posterior parietal cortex (PPC) and the prefrontal cortex (PFC). The PPC is involved in the control of attention and plays an important role in the detection of visual targets, while the PFC is responsible for working memory and inhibitory control.
Applications of Attentional Blink
Attentional blink has important implications in many fields, including cognitive psychology, neuroscience, and computer science.
In cognitive psychology, attentional blink is used to understand the role of attention and working memory in human perception. In neuroscience, it is used to study the neural correlates of attention and consciousness. In computer science, it is used to develop algorithms that can simulate human perception and attentional processes.
Attentional Blink and Advertising
Attentional blink has a significant impact on advertising, particularly in the online space where consumers are constantly bombarded with advertising messages. Advertisers need to be aware of the attentional limitations of consumers and make conscious efforts to improve the effectiveness of their advertising message.
Studies have shown that advertisements placed in close proximity to each other are likely to suffer from attentional blink. As a result, advertisers need to ensure that their adverts are spaced out and that there is sufficient time between each ad for the consumer's visual processing capacity to recover.
In addition, advertisers need to ensure that their adverts stand out and capture the consumer's attention. A novel or attention-grabbing advert is less likely to suffer from attentional blink compared to a bland or mundane advert. Advertisers can also use emotional appeals and slogans to capture the consumer's attention and improve the effectiveness of their advertising message.
Conclusion
Attentional blink is a complex phenomenon that has important implications in many fields, including cognitive psychology, neuroscience, and computer science. It is a delay in the processing of the second stimulus when it is presented in a short time window immediately after the first stimulus.
The attentional blink phenomenon is thought to occur because of the processing limitations in our working memory.

Attentional blink has significant implications in advertising and marketers need to be aware of the attentional limitations of consumers and make conscious efforts to improve the effectiveness of their advertising messages.
